Image rebuild (skip scrape) / build (push) Failing after 1h37m12s
Dockerfile: self-contained image with corpus + Chroma + BM25 baked in. Drawbar's compose pulls + runs without volume mounts. Built from sources.json (labels schema), PRODUCT_NAME=crop_chem by default, HYBRID_SEARCH=true (always-on for production quality). RERANK_URL + OLLAMA_URL get set at compose time. .gitea/workflows/refresh.yml: monthly cron (1st @ 06:00 UTC) does full scrape → reindex → image push. Scrapes Bayer (~30 min) + EPA PPLS row-crop filtered (~7h). Skips reindex+push if no corpus diff. Tags pushed: :latest, :<sha12>, :corpus-<YYYY.MM.DD>. .gitea/workflows/image-only.yml: on-demand or auto on code-only pushes to main (paths: docs_mcp/, rag/, scrape/, requirements.txt, Dockerfile, sources.json). Reindexes from committed corpus, builds image, pushes. ~10 min vs ~9h full refresh. .gitignore: corpus/ now COMMITTED (4,159 labels, 265 MB of .md + sidecars). Lets image-only.yml rebuild indexes without re-scraping. chroma/ + bm25/ still gitignored (regenerable binary indexes). .dockerignore: drops venv, eval results, PLAN/README/CLAUDE.md, deploy/, .git/ — keeps the image lean. corpus + chroma + bm25 explicitly NOT in dockerignore (those go INTO the image).

|
||
|
||
Dear Christa Ellers-Kirk:
|
||
|
||
The application referred to above, submitted under the Federal Insecticide, Fungicide, and
|
||
Rodenticide Act (FIFRA), as amended, is acceptable under FIFRA section 3(c)(5).
|
||
|
||
You must submit and/or cite all data required for registration/reregistration/registration review
|
||
of your product when the Agency requires all registrants of similar products to submit such
|
||
data.
|
||
|
||
A stamped copy of your labeling is enclosed for your records. This labeling supersedes all
|
||
previously accepted labeling. You must submit one (1) copy of the final printed labeling before
|
||
you release the product for shipment with the new labeling. In accordance with 40 CFR
|
||
152.130(c), you may distribute or sell this product under the previously approved labeling for
|
||
18 months from the date of this letter. After 18 months, you may only distribute or sell this
|
||
product if it bears this new revised labeling or subsequently approved labeling. “To distribute or
|
||
sell” is defined under FIFRA section 2(gg) and its implementing regulation at 40 CFR 152.3.
|
||
|
||
Should you wish to add/retain a reference to the company’s website on your label, then please
|
||
be aware that the website becomes labeling under FIFRA and is subject to review by the
|
||
Agency. If the website is false or misleading, the product would be misbranded and unlawful to
|
||
sell or distribute under FIFRA section 12(a)(1)(E). 40 CFR 156.10(a)(5) lists examples of
|
||
statements EPA may consider false or misleading. In addition, regardless of whether a website
|
||
is referenced on your product’s label, claims made on the website may not substantially differ

||
|
||

|
||
EPA Reg. No. 241-418
|
||
Case No. 477972
|
||
|
||
from those claims approved through the registration process. Therefore, should the Agency find
|
||
or if it is brought to our attention that a website contains false or misleading statements or
|
||
claims substantially differing from the EPA approved registration, the website will be referred
|
||
to the EPA’s Office of Enforcement and Compliance.
|
||
|
||
Your release for shipment of the product constitutes acceptance of these conditions. If these
|
||
conditions are not complied with, the registration will be subject to cancellation in accordance
|
||
with FIFRA section 6.

||
Mode of Action
|
||
Pendimethalin, the active ingredient in Prowl H2O , is a
|
||
Group 3 (WSSA) /Group K1 (HRAC) herbicide belonging
|
||
to the dinitroaniline chemistry class. Prowl H2O is a
|
||
meristematic inhibitor that interferes with meristematic
|
||
plant cell division or mitosis inhibiting germinating seedling
|
||
growth.
|
||
Herbicide Resistance Management
|
||
Prowl H2O is a Group 3 herbicide. Any weed population
|
||
may contain or develop plants naturally resistant to
|
||
Prowl H2O and other Group 3 herbicides. Weed species
|
||
with resistance to Group 3 may eventually dominate the
|
||
weed population if Group 3 herbicides are used repeated -
|
||
ly in the same field or in successive years as the primary
|
||
method of control for targeted species. This may result in
|
||
partial or total loss of control of those species by
|
||
Prowl H2O or other Group 3 herbicides.
|
||
To delay herbicide resistance consider:
|
||
• Avoiding the consecutive use of Prowl H2O or other tar-
|
||
get site-of-action Group 3 herbicides that have a similar
|
||
target site of action on the same weed species.
|
||
• Using tank mixes or premixes with herbicides from differ -
|
||
ent target-site-of-action groups as long as the involved
|
||
products are all registered for the same use, have differ-
|
||
ent sites of action, and are both effective at the tank mix
|
||
or prepack rate on the weed(s) of concern.
|
||
• Basing herbicide use on a comprehensive IPM (Integrat-
|
||
ed Pest Management) program including cultural and
|
||
mechanical methods.
|
||
• Monitoring treated weed populations for loss of field effi -
|
||
cacy, and control of escapes with effective alternative
|
||
herbicides or mechanical methods.
|
||
• Identify weeds present in the field through scouting and
|
||
field history and understand their biology. The weed-
|
||
control program needs to consider all of the weeds
|
||
present.
|
||
• Scout fields prior to application to identify the weed spe -
|
||
cies present and their growth stage to determine if the
|
||
intended application will be effective.
|
||
|
||
7
|
||
• Scout fields after application to verify the treatment was
|
||
effective.
|
||
• Suspected herbicide-resistance weeds may be identified
|
||
by these indicators:
|
||
1. Failure to control a weed species normally controlled
|
||
by the herbicide at the dose applied, especially if con -
|
||
trol is achieved on adjacent weeds;
|
||
2. A spreading patch of non-controlled plants of a par-
|
||
ticular weed species; and
|
||
3. Surviving plants mixed with controlled individuals of
|
||
the same species.
|
||
• If resistance is suspected, treat weed escapes with an
|
||
herbicide with a different MOA and/or use non-chemical
|
||
methods to remove escapes, as practical, with the goal
|
||
of preventing further seed production.
|
||
• Report any incidence of non-performance of this product
|
||
against a particular weed species to your local BASF
|
||
representative.
|
||
• Contacting your local extension specialist, certified crop
|
||
advisors, and/or manufacturer for herbicide resistance
|
||
management and/or integrated weed management
|
||
directions for specific crops and resistant weed biotypes.

Application Rate
|
||
Use rates for Prowl® H2O herbicide when used alone, in
|
||
tank mix, or for sequential applications are given in
|
||
Crop-specific Information . Use rates of this product
|
||
vary by soil texture and organic matter. See Table 5 for
|
||
soil texture groupings used in this label.
|
||
DO NOT apply more than the maximum labeled rate of
|
||
Prowl H2O for any soil type.

peat and muck soils, but weed control may be inconsis -
|
||
tent and/or reduced. Use maximum labeled use rate
|
||
allowed in the specific crop.
|
||
Application Timings
|
||
Prowl H2O will provide most effective weed control when
|
||
applied by ground or aerial equipment and subsequently
|
||
incorporated into soil by rainfall, sprinkler irrigation, or
|
||
mechanical tillage before weed seedling germination.
|
||
Prowl H2O can also be applied through chemigation,
|
||
including flooded basin irrigation systems. Prowl H2O
|
||
may be applied preplant surface, preplant incorporated,
|
||
surface incorporated, preemergence, early postemer -
|
||
gence, postemergence incorporated (CULTI-SPRAY), or by
|
||
layby treatment. See Crop-specific Information for spe-
|
||
cific application directions and restrictions by crop.
|
||
Preplant Surface Application. For use in minimum-
|
||
tillage or no-tillage production systems, apply Prowl H2O
|
||
alone or in tank mixes within 45 days of planting. When
|
||
making early preplant surface application (15 to 45 days
|
||
before planting), Prowl H2O should be tank mixed or fol-
|
||
lowed by a postemergence herbicide application. Rainfall
|
||
or sprinkler irrigation after application is required to move
|
||
this product into the upper soil surface where weed seeds
|
||
germinate.
|
||
Preplant Incorporated Application. Apply Prowl H2O
|
||
and incorporate into the upper (1 inch to 2 inches) soil
|
||
surface within 60 days of planting. Use an implement
|
||
capable of giving uniform incorporation; two-pass incorpo -
|
||
ration usually results in a more consistent result.
|
||
Surface Incorporated Application. Uniformly apply
|
||
Prowl H2O as broadcast or banded treatment to soil sur-
|
||
face underneath established trees and/or in ground areas
|
||
between trees rows. Incorporate into upper (1 inch to
|
||
2 inches) soil surface using rainfall, sprinkler irrigation, or
|
||
shallow mechanical incorporation using an implement
|
||
capable of giving uniform incorporation; two-pass
|
||
mechanical incorporation usually results in a more consis -
|
||
tent result.
|
||
Preemergence Surface Application. Broadcast treat-
|
||
ment uniformly to the soil surface at planting and up to
|
||
2 days after planting (refer to Crop-specific Information
|
||
section for exceptions). Rainfall, sprinkler irrigation, or shal-
|
||
low mechanical incorporation after application is required
|
||
to move this product into the upper soil surface where
|
||
weed seeds germinate. If adequate rainfall or irrigation
|
||
does not occur, or soil crusting or soil compaction has
|
||
occurred, and weed seedling emergence begins, a shal -
|
||
low cultivation or rotary hoeing or light harrow will improve
|
||
performance. Make sure that crop seeds are below the
|
||
tilled soil surface area.
|
||
Early Postemergence Application. Prowl H2O must
|
||
be applied before weed seedling emergence or in a tank
|
||
mix with products that control the emerged weeds. Refer
|
||
to Crop-specific Information for specific postemer-
|
||
gence application instructions by crop.
|
||
Postemergence Incorporated Application (CULTI-
|
||
SPRAY). Before application, crop must be cultivated in
|
||
such a manner as to throw at least 1 inch of soil over the
|
||
base of the crop plants. This will prevent direct contact of
|
||
Prowl H2O and the zone of brace root formation.
|
||
Prowl H2O must be applied broadcast with a ground
|
||
sprayer when crop is at least 4 inches tall up to layby. Use
|
||
drop nozzles if crop foliage will prevent uniform coverage
|
||
of the soil surface within the rows. Thoroughly and uni -
|
||
formly incorporate Prowl H2O treatments into the soil:
|
||
1. With a sweep-type or rolling cultivator set to provide
|
||
thorough incorporation in the top 1 inch of soil, or
|
||
2. With adequate overhead irrigation water or rainfall. See
|
||
Crop-specific Information (Corn and Grain
|
||
Sorghum) for more details on (CULTI-SPRAY)
|
||
application.
|
||
|
||
8
|
||
Layby Application. Apply Prowl® H2O herbicide
|
||
directly to the soil between rows as a directed spray after
|
||
the last normal cultivation (layby). See Crop-specific
|
||
Information for more details on layby application.
|
||
Split Application. Prowl H2O may be applied preplant
|
||
incorporated within 60 days of planting and followed by a
|
||
preemergence application at planting or up to 2 days after
|
||
planting (refer to Crop-specific Information section for
|
||
exceptions). The total amount of Prowl H2O applied per
|
||
acre per year cannot exceed the highest labeled rate for
|
||
any given soil type. See Crop-specific Information for
|
||
more details on split applications.
|
||
Fall Application. Prowl H2O may be used in fall applica-
|
||
tion programs in certain crops. See Crop- specific
|
||
Information for details on fall application timing.
|
||
Application Instructions
|
||
Prowl H2O may be applied using water or sprayable fluid
|
||
fertilizer (including straight 32-0-0 or 28-0-0) as the spray
|
||
carrier. DO NOT apply Prowl H2O after crop emergence
|
||
(postemergence) in sprayable liquid fertilizers. Additionally,
|
||
Prowl H2O may be impregnated on dry bulk fertilizer. For
|
||
all applications, avoid overlapping that could result in pos -
|
||
sible crop injury.
|
||
Spray Mix Compatibility Test
|
||
If liquid fertilizer and/or herbicide(s) mixture separates in
|
||
the spray tank, clogged equipment and uneven application
|
||
can result. Always predetermine the compatibility of
|
||
Prowl H2O alone or with other herbicides based on the
|
||
following compatibility jar test:
|
||
1. Add 1 pint of fertilizer to a quart jar.
|
||
2. Add 1 to 4 teaspoon(s) of the dry flowable (DF), wettable
|
||
powder (WP), aqueous solution (AS), flowable (F), or liq-
|
||
uid (L) formulation (depending on mixing ratio required)
|
||
to the liquid fertilizer. To calculate teaspoons of the for-
|
||
mulation to add:
|
||
lbs or pts of product/acre x 11.4 =
|
||
teaspoons of
|
||
herbicide to add to
|
||
1 pint of fertilizergallons of fertilizer/acre
|
||
3. Close the jar and agitate until the herbicide(s) are evenly
|
||
dispersed in the liquid fertilizer. If the materials do not
|
||
disperse well, it may be necessary to slurry the chemi -
|
||
cals in water before adding to the fertilizer.
|
||
4. After dispersing the materials, add appropriate number
|
||
of teaspoons of Prowl H2O to the jar and shake well.
|
||
Add water soluble concentrate herbicides to the mixture
|
||
last and agitate. Let the mixture stand for 30 minutes;
|
||
then observe the results. Look for signs of separation:
|
||
an oily layer or globules, sludge, flakes or other
|
||
precipitates.
|
||
5. Evaluate compatibility.
|
||
a. If the herbicide(s) and liquid fertilizer mixture does not
|
||
separate, use this mixture in your spray tank.
|
||
b. If the mixture separates but mixes readily with shak-
|
||
ing, the mixture can be used if good agitation is
|
||
maintained in the spray tank.
|
||
c. If separation of the mixture occurs and agitation does
|
||
not correct this problem, a compatibility agent is
|
||
needed.
|
||
6. If the need for a compatibility agent is demonstrated,
|
||
BASF recommends the following procedure: Using a
|
||
clean quart jar, repeat step 1 above and add 1/2 tea-
|
||
spoon of the compatibility agent to the liquid fertilizer.
|
||
Mix well and repeat steps 2, 3, and 4. If separation or
|
||
precipitation occurs with the compatibility agent,
|
||
DO NOT use Prowl H2O with that specific liquid
|
||
fertilizer.
|
||
Aerial Application
|
||
Uniformly apply in 5 or more gallons of water per acre.
|
||
Spray Drift Management for Aerial
|
||
Applications
|
||
• DO NOT release spray at a height greater than 10 ft
|
||
above the crop canopy, unless a greater application
|
||
height is necessary for pilot safety.
|
||
• Applicators are required to use a medium or coarser
|
||
droplet size (ASABE S572.1).
|
||
• DO NOT apply when wind speeds exceed 15 mph at the
|
||
application site. If the wind speed is greater than 10 mph,
|
||
the boom length must not exceed 65% of the wingspan
|
||
for fixed wing aircraft or 75% of the rotor diameter for
|
||
helicopters. Otherwise, the boom length must not
|
||
exceed 75% of the wingspan for fixed wing aircraft or
|
||
90% of the rotor diameter for helicopters.
|
||
• Applicators must use 1/2 swath displacement upwind at
|
||
the downwind edge of the field.
|
||
• Nozzles must be oriented so the spray is directed toward
|
||
the back of the aircraft.
|
||
• DO NOT apply during temperature inversions.
|
||
Ground Application (Broadcast)
|
||
Uniformly apply in 10 or more gallons of water per acre or
|
||
20 or more gallons of liquid fertilizer per acre. Keep the
|
||
bypass line on or near the bottom of the tank to minimize
|
||
foaming. Nozzle and in-line screens must be no finer than
|
||
50 mesh.
|
||
Ground Application (Band)
|
||
Uniformly apply the broadcast equivalent rate and volume
|
||
per acre. Calculate:
|
||
band width in inches x broadcast rate
|
||
per acre = band rate
|
||
per acrerow width in inches
|
||
band width in inches x broadcast
|
||
volume per acre = band volume
|
||
per acrerow width in inches
|
||
Spray Drift Management for Ground
|
||
Applications:
|
||
• Applicators must only apply with the nozzle height rec -
|
||
ommended by the manufacturer, but no more than 3 feet
|
||
above the ground or crop canopy.
|
||
• Applicators are required to use a medium or coarser
|
||
droplet size (ASABE S572.1).
|
||
|
||

hour at the application site.
|
||
• DO NOT apply during temperature inversions.
|
||
Ground Application (Dry Bulk Fertilizer)
|
||
Apply Prowl® H2O herbicide/dry bulk fertilizer mixtures
|
||
only with ground equipment. See Crop-specific
|
||
Information for crops suitable for dry bulk fertilizer appli -
|
||
cations. DO NOT impregnate Prowl H2O onto coated
|
||
ammonium nitrate or limestone because these materials
|
||
will not absorb the herbicide. Dry fertilizer blends contain -
|
||
ing mixtures of ammonium nitrate or limestone may be
|
||
impregnated with Prowl H2O . A minimum of 200 pounds
|
||
of impregnated dry bulk fertili zer, excluding the weight of
|
||
ammonium nitrate or limestone, must be applied per acre.
|
||
Calculate the amount of Prowl H2O impregnated on a ton
|
||
of dry bulk fertili zer based on the rate of fertili zer to be
|
||
applied per acre:
|
||
2000
|
||
x Prowl H2O
|
||
(rate per acre) = Prowl H2O per
|
||
ton of fertilizerpounds of dry
|
||
fertilizer per acre
|
||
To impregnate Prowl H2O on bulk fertilizer, use a closed
|
||
rotary-drum mixer or other commonly used dry bulk fertili -
|
||
zer blender equipped with suitable spray equipment. Spray
|
||
nozzles must be placed to provide uniform coverage of
|
||
Prowl H2O onto the fertilizer during mixing.
|
||
Apply the Prowl H2O /dry bulk fertilizer mixture with a cali -
|
||
brated dry fertilizer spreader. The Prowl H2O /dry bulk
|
||
fertilizer mixture must be spread uniformly on the soil
|
||
surface.
|
||
Chemigation Application via Sprinkler
|
||
Irrigation and Drip Irrigation Systems
|
||
Prowl H2O may be applied as a chemigation treatment
|
||
through sprinkler irrigation and drip irrigation systems.
|
||
Refer to Crop-specific Information sections for
|
||
individual crops. DO NOT apply Prowl H2O via chemiga-
|
||
tion to crops unless specified in Crop-specific
|
||
Information section.
|
||
Apply this product ONLY through a sprinkler irrigation sys-
|
||
tem of the following type: center pivot, lateral move, end
|
||
tow, side (wheel) roll, traveler, big gun, solid set, or hand
|
||
move.
|
||
Apply this product ONLY through a drip irrigation system
|
||
that has emitters above the soil surface.
|
||
DO NOT apply this product through any other type
|
||
of sprinkler irrigation or drip irrigation system.
|
||
Uniform distribution of Prowl H2O -treated irrigation water
|
||
is the sole responsibility of the applicator and is required to
|
||
avoid crop injury, lack of herbicide effectiveness, or illegal
|
||
pesticide residues in the crop. If you have any questions
|
||
about calibration, contact State Extension Service special -
|
||
ists, equipment manufacturers, or other experts.
|
||
The system must be calibrated (with water only) to ensure
|
||
the amount of Prowl H2O applied corresponds to the
|
||
specified rate. Apply Prowl H2O in 1/2 to 3/4 inch of water
|
||
during the first sprinkler set (use at least 1 inch of water in
|
||
the states of New Mexico, Oklahoma, and Texas). BASF
|
||
recommends mixing Prowl H2O with water at a 1:1 ratio
|
||
in the injection nurse tank to assist with product flowability.
|
||
Maintain agitation in the injection nurse tank to keep a uni -
|
||
form herbicide suspension during application. When
|
||
application is complete, flush the system with water.
|
||
Chemigation Instructions
|
||
(for low-volume micro sprinklers)
|
||
Output of low-volume sprinkler equals 4 to 50 gallons per
|
||
hour (gph) per emitter. Point of application MUST be
|
||
above ground.
|
||
Irrigation system must run a sufficient amount of time
|
||
before Prowl H2O injection to have all emitters functioning
|
||
properly. After system is operating properly, length of injec-
|
||
tion must be such that at one period of time during the
|
||
injection, the first and last emitters in the system contain
|
||
Prowl H2O -treated water. Add Prowl H2O to the supply
|
||
tank already filled with the volume of water required for the
|
||
injection period. Maintain agitation in Prowl H2O injection
|
||
tank. Mix Prowl H2O in clean water and inject down-line
|
||
from filters. After Prowl H2O injection, flush system for a
|
||
period of time sufficient to clear the line of Prowl H2O . (If
|
||
Prowl H2O is applied during a normal irrigation cycle,
|
||
make injection during the last stage.)
|
||
Chemigation Calibration
|
||
(for low-volume micro sprinklers)
|
||
Calculation of use rate is based on wetted area around
|
||
emitters - NOT on tree acres. To calculate amount of
|
||
Prowl H2O :
|
||
1. Treated area per each emitter = A
|
||
A = 3.14 x (radius x radius)
|
||
2. The area in square feet
|
||
wet in each acre = B B = A x emitters/acre
|
||
144
|
||
3. The total area (in square feet) wet by your system = C
|
||
C = B x acres covered by system
|
||
4. Rate per treated acre of Prowl H2O
|
||
(based on length of control desired) = R
|
||
Amount of
|
||
Prowl H2O
|
||
to inject = S
|
||
S =
|
||
C
|
||
x R = qts of Prowl H2O
|
||
43,560
|
||
|
||

|
||
Example:
|
||
If the average distance from emitter to perimeter of wetted
|
||
area measured 1 inch below soil surface is 13 inches, then
|
||
A = 3.14 x (13 inches x 13 inches)
|
||
and A = 530.7 square inches
|
||
If there are 300 emitters per acre, then
|
||
B =

Special Instructions for Chemigation
|
||
1. DO NOT apply when wind speed favors drift beyond
|
||
the area intended for treatment.
|
||
2. DO NOT connect an irrigation system used for pesticide
|
||
application to a public water system unless the pesticide
|
||
label prescribed safety devices for public water systems
|
||
are in place.
|
||
3. A person knowledgeable of the chemigation system and
|
||
responsible for its operation, or under the supervision of
|
||
the responsible person, shall shut the system down and
|
||
make necessary adjustments should the need arise.
|
||
4. Recirculate and/or contain tail water (runoff water) from
|
||
chemigation that contains Prowl H2O in the field in a
|
||
cistern or holding reservoir from the initial application
|
||
and/or use only on adjacent, approved crops for which
|
||
Prowl H2O is registered for this type of application.
|
||
5. The pesticide injection pipeline must contain a function -
|
||
al, automatic, quick-closing check valve to prevent the
|
||
flow of fluid back toward the injection pump. It must also
|
||
contain a functional, normally closed, solenoid-operated
|
||
valve located on the intake side of the injection pump
|
||
and connected to the system interlock to prevent fluid
|
||
from being withdrawn from the supply tank when the
|
||
irrigation system is automatically or manually shut down.
|
||
6. The sprinkler chemigation system must contain a func -
|
||
tional check valve, vacuum relief valve, and low- pressure
|
||
drain appropriately located on the irrigation pipeline to
|
||
prevent water source contamination from backflow. In
|
||
addition, systems must use a metering pump, including
|
||
a positive displacement injection pump (e.g. diaphragm
|
||
pump) effectively designed and constructed of materials
|
||
that are compatible with pesticides and capable of
|
||
being fitted with a system interlock.
|
||
7 . The sprinkler chemigation system must contain function -
|
||
al interlocking controls to automatically shut off the
|
||
pesticide injection pump when the water pump motor
|
||
stops, or in cases where there is no water pump, when
|
||
the water pressure decreases to the point where pesti-
|
||
cide distribution is adversely affected.
|
||
8. The irrigation line or water pump must include a func -
|
||
tional pressure switch that will stop the water pump
|
||
motor when the water pressure decreases to the point
|
||
where pesticide distribution is adversely affected.
|
||
Chemigation Systems Connected to Public
|
||
Water Systems
|
||
1. Public water system means a system for the provision to
|
||
the public of piped water for human consumption if such
|
||
system has at least 15 service connections or regularly
|
||
serves an average of at least 25 individuals daily at least
|
||
60 days out of the year.
|
||
2. Chemigation systems connected to public water sys-
|
||
tems must contain a functional, reduced-pressure zone
|
||
backflow preventer (RPZ) or the functional equivalent in
|
||
the water supply line upstream from the point of pesti-
|
||
cide introduction. As an option to the RPZ, discharge
|
||
the water from the public water system into a reservoir
|
||
tank prior to pesticide introduction. There shall be a
|
||
complete physical break (air gap) between the outlet
|
||
end of the fill pipe and the top or overflow rim of the res-
|
||
ervoir tank of at least twice the inside diameter of the fill
|
||
pipe.
|
||
3. All chemigation systems connected to public water sys-
|
||
tems must also follow restrictions listed in the preceding
|
||
sections involving Chemigation.
|
||
Application via Flood, Flooded Basin, or
|
||
Gravity Flow Irrigation Systems
|
||
Prowl H2O may be applied via flood, flooded basin, or
|
||
gravity flow irrigation systems, but only to the following
|
||
crops: alfalfa, bearing and nonbearing fruit and nut trees,
|
||
bearing and nonbearing bushberries and caneberries,
|
||
bearing and nonbearing olive trees, bearing and nonbear -
|
||
ing vineyards, bearing and nonbearing small fruit climbing
|
||
vines, and nonbearing date palm.
|
||
Use Instructions and Restrictions for Flood,
|
||
Flooded Basin, and Gravity Flow Irrigation
|
||
1. Prowl H2O may be applied through flood, flooded
|
||
basin, or gravity flow irrigation systems designed to
|
||
uniformly distribute irrigation water along the soil sur-
|
||
face. Solid set systems using tall riser for overhead
|
||
application are excluded.
|
||
2. Follow all label directions for Prowl H2O regarding
|
||
rates per acre, timing of application, and crop-specific
|
||
restrictions and precautions.
|
||
3. DO NOT connect an irrigation system used for pesti -
|
||
cide application to a public water system unless the
|
||
pesticide label prescribed safety devices for public
|
||
water systems are in place.
|
||
4. A person knowledgeable of the chemigation system
|
||
and responsible for its operation, or under the supervi -
|
||
sion of the responsible person, shall shut the system
|
||
down and make necessary adjustments should the
|
||
need arise.
|
||
5. BASF recommends that Prowl H2O is mixed with
|
||
water at a 1:1 ratio in the injection nurse tank to assist
|
||
with product flowability. Maintain agitation in the
|
||
injection nurse tank to keep a uniform herbicide
|
||
suspension during application. When application is
|
||
complete, flush the system with water.
|
||
|
||
11
|
||
6. Systems using a gravity-flow pesticide dispensing sys-
|
||
tem must meter the pesticide in the water at the head of
|
||
the field downstream of a hydraulic discontinuity, includ-
|
||
ing a drop structure or weir box, to decrease potential
|
||
for water source contamination from backflow water.
|
||
7. Tail water (runoff water) from flood, flooded basin, or
|
||
gravity flow irrigation that contains Prowl® H2O
|
||
herbicide must be recirculated and/or contained in the
|
||
field in a cistern or holding reservoir from the initial
|
||
application and/or used only on adjacent approved
|
||
crops for which Prowl H2O is registered for this type
|
||
of application.
|
||
8. Systems using a pressurized water and pesticide injec -
|
||
tion system must meet the following requirements:
|
||
• The system must contain a functional check valve,
|
||
vacuum relief valve, and low-pressure drain appropri-
|
||
ately located in the irrigation pipe to prevent water
|
||
source contamination from backflow.
|
||
• The pesticide injection pipeline must contain a func -
|
||
tional, automatic, quick-closing check valve to
|
||
prevent flow of fluids back toward the injection pump.
|
||
• The pesticide injection pipeline must also contain a
|
||
functional, normally closed solenoid-operated valve
|
||
located on the intake side of the injection pump and
|
||
connected to the system interlock to prevent fluid
|
||
from being withdrawn from the supply tank when the
|
||
irrigation system is automatically or manually shut
|
||
down.
|
||
• The system must contain a functional interlocking
|
||
control to automatically shut off the pesticide injec -
|
||
tion pump when the water pump stops.
|
||
• The irrigation pipe or water pump must include a
|
||
functional pressure switch, which will stop the pump
|
||
motor when the water pressure decreases to the
|
||
point where pesticide distribution is adversely
|
||
affected.
|
||
• Systems must use a metering pump, including a
|
||
positive displacement injection pump (e.g. diaphragm
|
||
pump) of effective design and constructed of materi-
|
||
als that are compatible with pesticides and capable
|
||
of being fitted with a system interlock.
|
||
• Any alternative to the above safety devices must con-
|
||
form to the list of EPA-approved alternative devices.
|
||
9. Regularly measure the flow in the field to ensure the
|
||
correct amount of Prowl H2O is metered into irrigation
|
||
water and also regularly monitor to ensure treated
|
||
water is uniformly distributed across the field. Flow
|
||
rates through metering devices and distribution of
|
||
Prowl H2O can vary with water temperature and
|
||
speed of water flow across the field.
|
||
10. Uniform distribution of Prowl H2O -treated irrigation
|
||
water is the sole responsibility of the applicator and is
|
||
required to avoid crop injury, lack of herbicide effective-
|
||
ness, or illegal pesticide residues in the crop.
|
||
11. For questions about calibration, contact State Exten -
|
||
sion Service specialists, equipment manufacturers or
|
||
other experts.
|
||
Spray Drift Advisories
|
||
The applicator is responsible for avoiding off-site spray
|
||
drift. Be aware of nearby nontarget sites and environmen -
|
||
tal conditions.
|
||
Importance of Droplet Size
|
||
An effective way to reduce spray drift is to apply large
|
||
droplets. Use the largest droplets that provide target pest
|
||
control. While applying larger droplets will reduce spray
|
||
drift, the potential for drift will be greater if applications are
|
||
made improperly or under unfavorable environmental
|
||
conditions.
|
||
Controlling Droplet Size – Ground Boom
|
||
• Volume - Increasing the spray volume so that larger
|
||
droplets are produced will reduce spray drift. Use the
|
||
highest practical spray volume for the application. If a
|
||
greater spray volume is needed, consider using a nozzle
|
||
with a higher flow rate.
|
||
• Pressure - Use the lowest spray pressure recommend-
|
||
ed for the nozzle to produce the target spray volume and
|
||
droplet size.
|
||
• Spray Nozzle - Use a spray nozzle that is designed for
|
||
the intended application. Consider using nozzles
|
||
designed to reduce drift.
|
||
Controlling Droplet Size – Aircraft
|
||
• Adjust Nozzles - Follow nozzle manufacturer’s recom-
|
||
mendations for setting up nozzles. Generally, to reduce
|
||
fine droplets, nozzles should be oriented parallel with the
|
||
airflow in flight.
|
||
Boom Height - Ground Boom
|
||
For ground equipment, the boom must remain level with
|
||
the crop and have minimal bounce.
|
||
Release Height - Aircraft
|
||
Higher release heights increase the potential for spray drift.
|
||
Shielded Sprayers
|
||
Shielding the boom or individual nozzles can reduce spray
|
||
drift. Consider using shielded sprayers. Verify that the
|
||
shields are not interfering with the uniform deposition of
|
||
the spray on the target area.
|
||
Temperature and Humidity
|
||
When making applications in hot and dry conditions, use
|
||
larger droplets to reduce effects of evaporation.
|
||
Temperature Inversion
|
||
Drift potential is high during a temperature inversion. Tem-
|
||
perature inversions are characterized by increasing
|
||
temperature with altitude and are common on nights with
|
||
limited cloud cover and light to no wind. The presence of
|
||
an inversion can be indicated by ground fog or by the
|
||
movement of smoke from a ground source or an aircraft
|
||
smoke generator. Smoke that layers and moves laterally in
|
||
a concentrated cloud (under low wind conditions) indicates
|
||
an inversion, while smoke that moves upward and rapidly
|
||
dissipates indicates good vertical air mixing. Avoid applica -
|
||
tions during temperature inversions.
|
||
|
||
12
|
||
Wind
|
||
Drift potential generally increases with wind speed. AVOID
|
||
APPLICATIONS DURING GUSTY WIND CONDITIONS.
|
||
Applicators need to be familiar with local wind patterns
|
||
and terrain that could affect spray drift.
|
||
Additives
|
||
Spray adjuvants have little or no influence on performance
|
||
of Prowl® H2O herbicide when applications are made
|
||
before weed emergence. However, several tank mixes with
|
||
Prowl H2O require adjuvants to improve burndown of
|
||
emerged weeds. Therefore, surfactants, liquid fertilizer
|
||
(28%, 30%, or 32% UAN [urea ammonium nitrate] or AMS
|
||
[ammonium sulfate]), or crop oil concentrate (COC) may be
|
||
used with Prowl H2O tank mixes applied preplant, pre-
|
||
emergence, or early postemergence to the crop. Follow
|
||
the adjuvant directions on the tank mix partner’s label. The
|
||
adjuvants must contain ingredients accepted by the Envi-
|
||
ronmental Protection Agency.
|
||
When an adjuvant is to be used with this product, BASF
|
||
recommends the use of a Chemical Producers and Dis -
|
||
tributors Association certified adjuvant.
|
||
Tank Mixing Information
|
||
It is the pesticide user’s responsibility to ensure that all
|
||
products in the listed mixtures are registered for the
|
||
intended use. Read and follow the applicable restrictions
|
||
and limitations and directions for use on all product labels
|
||
involved in tank mixing. Users must follow the most restric -
|
||
tive directions for use and precautionary statements of
|
||
each product in the tank mixture.
|
||
Prowl H2O may be tank mixed or applied sequentially
|
||
with other herbicide products registered for use in any
|
||
labeled crop found in this label for a broader spectrum of
|
||
residual weed control and/or control of emerged weeds.
|
||
Refer to the tank mix product labels to confirm that the
|
||
respective tank mix products are registered for use on the
|
||
labeled crop. Read and follow tank mix product labels for
|
||
application instructions, use restrictions and precautions,
|
||
and rotational cropping guidance. The most restrictive
|
||
labeling applies to tank mixes. Always perform a mixing
|
||
test to check the compatibility of Prowl H2O with all
|
||
potential tank mix partners.
|
||
Mixing Instructions
|
||
1. Fill tank 1/2 to 3/4 full with clean water or liquid fertilizer
|
||
and agitate. Before mixing Prowl H2O or Prowl H2O
|
||
tank mixes in liquid fertilizer, refer to appropriate label
|
||
sections for specified uses in liquid fertilizer, application
|
||
instructions, and compatibility determinations.
|
||
NOTE: Prowl H2O will NOT mix in high salt formulation
|
||
fertilizers, including 10-34-0. When using high salt for-
|
||
mulation fertilizers as the spray carrier, use one of the
|
||
following:
|
||
a. Pre-slurry Prowl H2O in water before adding to tank;
|
||
use 1:1 ratio of water to Prowl H2O .
|
||
b. Add water to fertilizer solution before adding
|
||
Prowl H2O . The amount of water must be equal to or
|
||
more than the amount of Prowl H2O to be used.
|
||
2. Prowl H2O Alone
|
||
When using Prowl H2O alone, add Prowl H2O to the
|
||
partially filled tank while agitating; then fill the remainder
|
||
of the tank with water or liquid fertilizer.
|
||
3. Prowl H2O Tank Mixes
|
||
Add the tank mix ingredients in the following order
|
||
before adding Prowl H2O :
|
||
a. Wettable Powder (WP) formulations. Make a slur-
|
||
ry of the WP in water (1:2 ratio). Add the slurry slowly
|
||
into the partially filled tank while agitating.
|
||
b. Dry Flowable (DF)/Water-dispersible Granule
|
||
(WDG) formulations. Add the granules to the par-
|
||
tially filled tank while agitating. Make a slurry of the
|
||
granules in water before adding to liquid fertilizer.
|
||
c. Flowable (F) formulations. Add the F formulation to
|
||
the partially filled tank while agitating.
|
||
d. Add Prowl H2O to the partially filled tank while
|
||
agitating.
|
||
e. Water-soluble Concentrate (WSC) formulations.
|
||
Add the WSC formulation to the partially filled tank
|
||
while agitating.
|
||
f. Emulsifiable Concentrate (EC) formulations. Add
|
||
the EC formulation to the partially filled tank while
|
||
agitating.
|
||
Fill the remainder of the tank with water or liquid fertilizer
|
||
while agitating.
|
||
4. Thorough and continuous sprayer-tank agitation MUST
|
||
be maintained during mixing and spraying of
|
||
Prowl H2O . If the spray mixture is allowed to settle for
|
||
any period of time, thorough agitation is essential to
|
||
resuspend the mixture before spraying is resumed.
|
||
Cleaning Spray Equipment
|
||
Clean application equipment thoroughly by using a strong
|
||
detergent or commercial spray cleaner according to the
|
||
manufacturer’s directions; then triple rinse the equipment
|
||
before and after applying this product.
|
||
Use Precautions
|
||
• Prowl H2O will not control established weeds. Destroy
|
||
emerged weeds before application.
|
||
• Prowl H2O is most effective in controlling weeds when
|
||
mechanically incorporated or when incorporated into the
|
||
weed germination zone by adequate rainfall or overhead
|
||
irrigation after application.
|
||
• In the event of a crop loss because of adverse weather
|
||
conditions or other reasons, any crop registered for a
|
||
preplant incorporated application of Prowl H2O can be
|
||
replanted without adverse effects the same year (see
|
||
Crop-specific Information for exceptions). If replanting
|
||
is necessary, DO NOT work the soil deeper than the
|
||
treated zone.
|
||
• Refer to Crop-specific Information for crop-specific
|
||
preharvest intervals and feeding and grazing restrictions.
|
||
|
||
13
|
||
Use Area
|
||
Rotational Crop Restrictions
|
||
• Use of Prowl® H2O herbicide in accordance with label
|
||
directions is expected to result in normal growth of rota-
|
||
tional crops in most situations; however, various
|
||
environmental and agronomic factors, including arid con -
|
||
ditions, make it impossible to eliminate all risks
|
||
associated with the use of this product and, therefore,
|
||
rotational crop injury is always possible. Soil characteris -
|
||
tics and environmental conditions which may contribute
|
||
to crop stress that may be accentuated by the use of
|
||
Prowl H2O include: coarse soils, compaction, high
|
||
salinity, eroded knolls/hilltops, cold and/or wet soils,
|
||
drought, and heavy rainfall soon after application.
|
||
• When Prowl H2O is used in tank mix or sequential com -
|
||
binations, refer to label of other herbicides for additional
|
||
rotational crop restrictions.
|
||
• After harvest of furrow-irrigated crops, thoroughly mix
|
||
the soil by plowing or deep disking to minimize the
|
||
potential for herbicide carryover to the following crop.
|
||
• Refer to Crop-specific Information for specific rota-
|
||
tional restrictions when Prowl H2O is applied to specific
|
||
crops.
|
||
• Restrictions for rotational cropping after the use
|
||
of Prowl H2O depend on the application use rate
|
||
of Prowl H2O in the primary crop. The user must
|
||
thoroughly read the following restrictions to deter -
|
||
mine the rotational crops for the specific situation,
|
||
according to application use rate. For field and
|
||
row crops, see the table following.
|
||
Orchard, Grove, and Vineyard Crops
|
||
In the growing season after application of Prowl H2O to
|
||
bearing fruit and nut trees, bushberries, caneberries, or
|
||
grapes, plant only those crops for which Prowl H2O is
|
||
labeled for preplant incorporated treatment or crop injury
|
||
may occur. DO NOT rotate to other crops (except for fruit
|
||
and nut trees, bushberries, caneberries, or grapes) for
|
||
24 months after Prowl H2O application.

Crop-specific Information
|
||
Crop Injury. Prowl ® H2O herbicide use may result in
|
||
crop injury, loss or damage to certain crops under a num -
|
||
ber of conditions, including but not limited to agronomic,
|
||
cultural, mechanical, and en vironmental. Numerous risks
|
||
of loss or damage to certain crops may be associated with
|
||
the use of Prowl H2O even when directions for use are
|
||
followed completely. The user or grower needs to take all
|
||
such risks into consideration before deciding to apply the
|
||
product. BASF recommends testing on a small por -
|
||
tion of the target crop to determine if damage is
|
||
likely to occur. Each grower who is considering the prod-
|
||
uct for such use should test Prowl H2O to determine its
|
||
suitability. A grower should use Prowl H2O only to the
|
||
extent that, in his sole opinion, the benefit of Prowl H2O
|
||
use outweighs the potential injury to the grower’s crop.
|
||
In addition, many factors can affect crop growth and/or
|
||
yield, including but not limited to insects, diseases, weed
|
||
competition, poor seed quality, improper planting depth,
|
||
mechanical cultivation, poor weather (including freezing or
|
||
excessive wind, rain, heat, or cold), lack of or excessive
|
||
moisture, crusting, fertility, or hardpans. Risk of loss or
|
||
damage to crops may be associated with the use of
|
||
Prowl H2O and contribute to poor stands because of
|
||
failure of crop to emerge, swelling of roots or other below-
|
||
ground plant parts, less vigorous plant growth and
|
||
development, and reduction in yield potential. Prowl H2O
|
||
may also cause injury to sensitive rotational crops.

African Marigold
|
||
Prowl H2O is only registered for use in African marigold
|
||
grown for the purpose of lutein and zeaxanthin extraction.
|
||
Prowl H2O may be applied by ground, chemigation, or on
|
||
dry bulk fertilizer.
|
||
Plant African marigold 1/4-inch to 3/4-inch deep and com-
|
||
pletely cover with soil. Make sure that crop seeds are
|
||
below the tilled soil surface area.
|
||
Use Method, Rate, and Timing
|
||
Prowl H2O may be applied in a single application or
|
||
sequentially with an interval of 30 days or more.
|
||
Uniformly apply Prowl H2O up to 4.2 pints per acre as a
|
||
broadcast treatment before target-weed germination.
|
||
Preplant Incorporated. Apply Prowl H2O within
|
||
60 days of planting and incorporate.
|
||
Preemergence. Apply Prowl H2O at planting or up to
|
||
2 days after planting, but before crop emerges. Apply to a
|
||
seedbed that is firm and free of clods.
|
||
Postemergence. Apply Prowl H2O over-the-top
|
||
postemergence after crop emergence for residual weed
|
||
control.
|
||
Postemergence-directed. Apply Prowl H2O as a
|
||
postemergence-directed spray on the soil at the base of
|
||
established plants, beneath plants, and between rows for
|
||
residual weed control. Avoid direct contact with foliage or
|
||
stems.
|
||
Postemergence and postemergence-directed treatments
|
||
are most effective in controlling weeds when adequate
|
||
rainfall or overhead irrigation is received after application. If
|
||
sufficient rainfall or irrigation does not occur to activate the
|
||
herbicide, mechanically incorporate. Apply Prowl H2O
|
||
before weeds germinate or after clean cultivation to
|
||
remove existing weeds because Prowl H2O will not con-
|
||
trol emerged weeds. Apply a postemergence herbicide to
|
||
control emerged weeds.
|
||
Crop-specific Restrictions
|
||
• DO NOT apply more than 4.2 pints of Prowl H2O per
|
||
acre in a single application.
|
||
• DO NOT apply more than a maximum cumulative total of
|
||
8.4 pints of Prowl H2O per acre per year.
|
||

|
||
plant materials to animals.
|
||
Crop-specific Precautions
|
||
• Avoid overlapping spray patterns because crop injury
|
||
can occur.
|
||
• Avoid heavy residue on soil surface from previous year’s
|
||
crops.
|
||
• Avoid applying Prowl H2O to open furrows with
|
||
exposed seed.

||
Alfalfa
|
||
(grown for Forage, Hay, or Seed)
|
||
Prowl H2O may be applied by ground; air; chemigation;
|
||
flood, flooded basin, and gravity flow irrigation systems; or
|
||
on dry bulk fertilizer.
|
||
Use Method, Rate, and Timing
|
||
Established Alfalfa for Forage/Hay and Seed
|
||
Production. Apply to estab lished alfalfa grown for forage
|
||
or hay or seed production (defined as alfalfa planted in the
|
||
fall or spring which has gone through a first cutting/
|
||
mowing). Apply in a single application or in sequential
|
||
applications. Uniformly apply Prowl H2O at a broadcast
|
||
rate of 1.1 to 4.2 quarts per acre before weed germination.
|
||
Application can be made in the fall after the last cutting/
|
||
mowing, during winter dormancy, in the spring, or between
|
||
cuttings. Apply before alfalfa reaches 6 inches in regrowth.
|
||
Seedling Alfalfa. Apply to seedling alfalfa grown for for-
|
||
age or hay or seed production (defined as alfalfa planted in
|
||
the fall or spring which has NOT gone through a cutting/
|
||
mowing/seed harvest). Uniformly apply Prowl H2O at a
|
||
broadcast rate of 1.1 to 2.1 pints per acre before weed ger-
|
||
mination. Application can be made when seedling alfalfa
|
||
has reached the second trifoliate growth stage. Apply
|
||
before alfalfa reaches 6 inches in growth.
|
||
Alfalfa Stand Establishment. Apply Prowl H2O at a
|
||
broadcast rate of 1.0 to 1.5 pints per acre as a preplant
|
||
incorporated or preemergence treatment in direct-seeded
|
||
alfalfa. Some crop stand reduction and stunting may occur
|
||
with this use of Prowl H2O ; however, reduced weed com-
|
||
petition will allow establishment of a quality stand. Use
|
||
|
||
16
|
||
lower rates on coarse-texture soil or in lower rainfall areas
|
||
(receiving less than 20 inches of rainfall and irrigation a
|
||
year).
|
||
• Preplant Incorporated. Uniformly incorporate
|
||
Prowl® H2O herbicide into the top 2 to 3 inches of the
|
||
final seedbed before planting.

|
||
Corn
|
||
(Field, Field Seed, Fresh Sweet,
|
||
Popcorn, and Popcorn Seed)
|
||
Prowl H2O may be applied by ground, air, chemigation,
|
||
or on dry bulk fertilizer. Prowl H2O may be applied in
|
||
conventional tillage, minimum tillage, or no-till as a
|
||
preemergence, postemergence, or postemergence incor-
|
||
porated ( CULTI-SPRAY) application in field corn.
|
||
Prowl H2O may be applied in conventional tillage as a
|
||
preemergence or postemergence application in field seed
|
||
corn, popcorn, popcorn seed corn, and fresh sweet corn.
|
||
Regardless of tillage system, plant corn at least
|
||
1-1/2 inches deep and completely cover with soil.
|
||
In conventional-tillage systems, plant into a seedbed that is
|
||
firm and free of clods and trash. Use only where tillage
|
||
provides good soil coverage of corn seed.
|
||
In no-till systems, use a no-till planter capable of planting
|
||
through crop residue. Use of no-till planters under condi-
|
||
tions that do not allow good soil coverage of the corn seed
|
||
can result in reduced crop stand or injury if Prowl H2O
|
||
contacts the germinating corn seed. Check equipment to
|
||
ensure good seed coverage.
|
||
Additional Weeds Controlled. In addition to weeds list-
|
||
ed in Table 2 , Prowl H2O controls the following weeds in
|
||
corn with CULTI-SPRAY application: wild proso millet and
|
||
shattercane.
|
||
Use Method, Rate, and Timing
|
||
Preemergence. Apply after planting but before weeds
|
||
germinate and crop emerges.
|
||
Postemergence. Apply postemergence until field corn is
|
||
30-inches tall (20-inches to 24-inches tall for popcorn,
|
||
popcorn seed, field seed, and fresh sweet corn) or in the
|
||
V8 growth stage, which ever is more restrictive. If the corn
|
||
canopy prevents applications from reaching the soil, use
|
||
drop nozzles and apply as a directed spray.
|
||
CULTI-SPRAY. Apply Prowl H2O alone or Prowl H2O
|
||
plus atrazine when field corn is at least 4-inches tall until
|
||
last cultivation (layby). Prowl H2O plus atrazine must be
|
||
applied before the field corn reaches 12 inches in height.
|
||
See specific directions for (CULTI-SPRAY) application
|
||
under Application Timings .
|
||
DO NOT apply more than 1.2 lbs ai per acre of
|
||
atrazine, as specified on the atrazine label. Under
|
||
situations of low rainfall or soil moisture, when deep germi -
|
||
nating weeds like shattercane or field sandbur are
|
||
anticipated, mechanical incorporation provides the best
|
||
results. If cultivation is needed after application and
|
||
incorporation of Prowl H2O , the depth of cut should be
|
||
no deeper than the depth of cut used to incorporate.
|
||
Chemigation Application
|
||
Prowl H2O may be applied through sprinkler irrigation
|
||
systems. Follow all directions, special instructions, and

||
as long as the total use rate applied in the year does not
|
||
exceed the highest rate per acre for any given soil type.
|
||
Cotton
|
||
Prowl H2O may be applied by ground, air, chemigation, or
|
||
on dry bulk fertilizer to cotton (including those varieties with
|
||
a herbicide-resistant trait) grown under conventional-
|
||
tillage, minimum-tillage, or no-till systems, or on stale
|
||
seedbeds.
|
||
|
||

|
||
Additional Weeds Suppressed. In addition to weeds
|
||
listed in Table 2 , Prowl® H2O herbicide will suppress
|
||
Russian thistle in the state of Arizona.
|
||
Use Method, Rate, and Timing
|
||
Fall Application. Prowl H2O may be applied for weed
|
||
control in cotton in the fall, after October 15 (up to
|
||
140 days before planting cotton) in Arizona, California,
|
||
Louisiana, Mississippi, New Mexico, Oklahoma, and Texas.
|
||
Apply Prowl H2O at the broadcast rate of 2.0 pints per
|
||
acre on coarse or medium soils and 3.0 pints per acre on
|
||
fine soils.
|
||
Preplant Surface. Apply Prowl H2O within 15 days of
|
||
planting.
|
||
Preplant Incorporated. Apply Prowl H2O within
|
||
60 days of planting and incorporate.
|
||
Preemergence. Apply Prowl H2O at planting or up to
|
||
2 days after planting. Apply to a seedbed that is firm and
|
||
free of clods.
|
||
Preplant Incorporated followed by Preemergence.
|
||
Apply Prowl H2O within 60 days of planting and incorpo-
|
||
rate. Apply overlay application of Prowl H2O at planting or
|
||
up to 2 days after planting. Total amount of Prowl H2O
|
||
applied per acre cannot exceed the highest labeled rate for
|
||
a given soil type. Preplant incorporated and preemergence
|
||
applications of Prowl H2O may be applied with the
|
||
labeled tank mix herbicide(s).
|
||
Layby Application (at last cultivation). Apply
|
||
Prowl H2O directly to the soil between rows as a directed
|
||
spray after the last normal cultivation (layby). Layby appli-
|
||
cations can be applied in cotton previously treated with
|
||
Prowl H2O or any herbicide(s) registered for use in cotton.
|
||
The total amount of Prowl H2O applied per acre per year
|
||
cannot exceed the highest labeled rate for a given soil
|
||
type. Prowl H2O may also be applied at layby in cotton
|
||
with herbicide-resistant traits.
|
||
Postemergence. Prowl H2O may be applied by ground
|
||
or air as a broadcast over-the-top postemergence applica-
|
||
tion in cotton, including those varieties with a
|
||
herbicide-resistant trait.
|
||
Postemergence treatments are most effective in controlling
|
||
weeds when adequate rainfall or overhead irrigation is
|
||
received after application. Apply Prowl H2O before weeds
|
||
germinate or after clean cultivation to remove existing
|
||
weeds because Prowl H2O will not control emerged
|
||
weeds. Apply a postemergence herbicide to control
|
||
emerged weeds.
|
||
Apply Prowl H2O broadcast postemergence (in water)
|
||
over the top of cotton after cotton reaches the 4-leaf
|
||
growth stage, but not after the 8-leaf growth stage. Over-
|
||
the-top applications made before the 4-leaf growth stage
|
||
or after the 8-leaf growth stage may result in crop injury
|
||
and/or yield loss.
|
||
Prowl H2O may also be tank mixed with herbicide prod-
|
||
ucts registered for use on cotton varieties with a
|
||
herbicide-resistant trait. When tank mixing Prowl H2O
|
||
with another herbicide product, always follow the most
|
||
restrictive labeling pertaining to application rates, methods,
|
||
timings and precautions. DO NOT tank mix and apply
|
||
over-the-top postemergence with fluometuron, gylphosate
|
||
plus s-metolachlor, prometryn, or pyrithiobac-sodium, or
|
||
s-metolachlor.
|
||
Dry ammonium sulfate (AMS) at 17 lbs/100 gallons of spray
|
||
solution must be used when tank mixing Prowl H2O with
|
||
glyphosate-containing products. Liquid AMS may also be
|
||
used, but must be used at an equivalent rate to 17 lbs of
|
||
dry weight AMS/100 gallons of spray solution. A nitrogen
|
||
replacement may not be used with this tank mix unless
|
||
specified as acceptable from BASF in writing. An appropri -
|
||
ate mixing order is as follows: fill tank to at least 1/2 full
|
||
with water; then add in order: AMS, Prowl H2O ,
|
||
glyphosate; then fill the tank to capacity with water.
|
||
Over-the-top postemergence application of Prowl H2O
|
||
can be applied in cotton previously treated with at-planting
|
||
soil applications of Prowl H2O or any other soil-applied
|
||
herbicide(s) registered for use in cotton. Consult the labels
|
||
of those herbicides for suggested treatments, rates,
|
||
precautions, or restrictions for use in cotton, and for rota-
|
||
tional crop restrictions. Follow the most restrictive label
|
||
instructions when using products in combination with
|
||
soil-applied Prowl H2O .
|
||
Precautions: Postemergence application of Prowl H2O
|
||
may cause temporary growth reduction and/or leaf dis -
|
||
coloration or malformation of cotton after application.
|
||
DO NOT apply over the top in fluid fertilizer.
|
||
DO NOT apply in tank mix with any adjuvant, surfactant,
|
||
oil, or other pesticide (except for cotton insecticides).
|
||
DO NOT apply in any manner except as described in this
|
||
label or crop injury and/or yield reduction may occur.
|
||
DO NOT apply if cotton is under stress (including stress
|
||
related to previous pesticide treatments, poor fertilization,
|
||
environmental conditions, and/or pest damage) at time of
|
||
application. If cotton is under stress (including stress relat -
|
||
ed to previous pesticide treatments, poor fertilization,
|
||
environmental conditions, and/or pest damage) at time of
|
||
application, Prowl H2O may retard cotton recovery and/or
|
||
adversely affect yield.
|
||
Chemigation Application
|
||
Prowl H2O may be applied through sprinkler irrigation
|
||
systems. Follow all directions, special instructions, and

State-specific Instructions
|
||
Idaho, Montana, North Dakota, Oregon, and
|
||
Washington
|
||
Prowl® H2O herbicide may be applied to chickpeas
|
||
grown in no- tillage and/or minimum tillage systems in
|
||
Idaho, Montana, North Dakota, Oregon, and Washington.
|
||
Preplant surface applications must be made within
|
||
30 days of planting. DO NOT apply more than 1.5, 2.0,
|
||
and 3.0 pts/A of Prowl H2O in coarse, medium, and fine
|
||
texture soils, respectively. When planting, ensure the seed
|
||
furrow is fully closed because conditions that allow the
|
||
seed furrow to inadequately close and/or allow
|
||
Prowl H2O to contact the seed may result in crop injury.
|
||
Certain unfavorable environmental conditions, including
|
||
cool temperatures, excessive moisture after application,
|
||
and wet and/or compacted soil conditions, may result in
|
||
delayed emergence and stunting with Prowl H2O use in
|
||
chickpea. Adequate rainfall or irrigation after application
|
||
before weed seedling germination provides the most effec -
|
||
tive weed control. Herbicide performance from surface
|
||
application may be decreased compared to soil incorpo -
|
||
rated application.
|
||
Idaho, Oregon, and Washington
|
||
Prowl H2O may be applied postplant preemergence only
|
||
to chickpea grown in conventional tillage systems in Idaho,
|
||
Oregon, and Washington. Application must be made with-
|
||
in 2 days of planting. Apply up to but not more than
|
||
1.5 pts/A. Apply to a firm seedbed free of clods. Soil con -
|
||
ditions that cause poor seed furrow closure and coverage
|
||
may result in delayed emergence and stunting of the crop.
|
||
Under certain environmental conditions, including cool
|
||
temperatures, excessive moisture after application and wet
|
||
soil conditions may result in delayed emergence and stunt -
|
||
ing with Prowl H2O use in chickpea. Adequate rainfall or
|
||
irrigation after application before weed seedling germina -
|
||
tion provides the most effective weed control.
|
||
Colorado, Idaho, Kansas, Montana, Nebraska, New
|
||
Mexico, Oregon, Washington, and Wyoming
|
||
Apply Prowl H2O by ground postplant preemergence to
|
||
dry beans grown under sprinkler irrigation in Colorado,
|
||
Idaho, Kansas, Montana, Nebraska, New Mexico, Oregon,
|
||
Washington, and Wyoming. Dry beans must have a
|
||
minimum planting depth of 2 inches. Before applying
|
||
Prowl H2O to dry beans, growers should check with their
|
||
local seed company or seed supplier for sensitive varieties
|
||
and to verify the selectivity of Prowl H2O on the grower’s
|
||
specific dry bean variety. Prowl H2O application made
|
||
postplant preemergence to dry beans must be immediate -
|
||
ly followed by 0.50 to 0.75 inch of water from overhead
|
||
irrigation/rainfall. Apply Prowl H2O within 1 to 4 days of
|
||
planting and up to but not more than 2.0 pts/A. Apply to a
|
||
firm seedbed free of clods. Soil conditions that cause poor
|
||
seed furrow closure and coverage may result in delayed
|
||
emergence and stunting of the crop. DO NOT apply as a
|
||
chemigation application. DO NOT apply Prowl H2O in
|
||
tank mix with halosulfuron or flumioxazin as a
|
||
preemergence application to dry beans because of unac -
|
||
ceptable crop response. Under certain environmental
|
||
conditions, including cool temperatures, excessive mois -
|
||
ture after application and wet soil conditions may result in
|
||
crop injury, delayed emergence, and/or stunting with
|
||
Prowl H2O use in dry beans. Adequate rainfall or irrigation
|
||
after application before weed seedling germination pro -
|
||
vides the most effective weed control.
|
||
Crop-specific Restrictions
|
||
• DO NOT feed lupin hay and forage or graze
|
||
livestock in treated lupin fields.
|
||
• DO NOT apply Prowl H2O more than once per year.
|
||
• DO NOT apply in any type of irrigation system.
|
||
Fallow
|
||
Prowl H2O may be applied to fallow ground following
|
||
crop harvest as a planned residual treatment to control
|
||
labeled broadleaf and grass weeds as they germinate.
|
||
Prowl H2O may be applied to fallow ground by ground,
|
||
air, or chemigation.
|
||
Use Method, Rate, and Timing
|
||
Apply as a broadcast spray at rates up to but not more
|
||
than 3.0 pts/A of Prowl H2O . Emerged weeds will not be
|
||
controlled by this treatment. Prowl H2O must be applied
|
||
with a tank mix partner (i.e. glyphosate) for control of
|
||
emerged weeds.
|
||
DO NOT make more than one application of Prowl H2O
|
||
during a single fallow period.
|
||
DO NOT apply Prowl H2O to fallow ground after July 1 if
|
||
treated fields are to be planted the following spring to
|
||
crops not labeled for preplant or preplant incorporated
|
||
applications of Prowl H2O .
|
||
There must be at least a 4-month interval between a
|
||
Prowl H2O fallow application and the rotational planting of
|
||
any fall-seeded cereal crop. Otherwise, specific rotational
|
||
crop intervals must be adhered to between a fallow appli -
|
||
cation of Prowl H2O and the planting of the following crop
|
||
(see Rotational Crop Restrictions section of this label).

|
||
Farmstead
|
||
Apply Prowl H2O as a broadcast spray at 2.1 qts/A for
|
||
short-term (2 to 4 months) or at 4.2 qts/A for long-term
|
||
(6 to 8 months) preemergence control of labeled broadleaf
|
||
and grass weeds as they germinate on farmstead nonagri -
|
||
cultural areas including barnyards, lanes, driveways,
|
||
machinery or implement yards, windbreaks, and nonagri -
|
||
cultural fencerows or ditchbanks.
|
||
Forage Grasses (Cool-season)
|
||
Prowl H2O may be applied by ground or chemigation, by
|
||
air, or on dry bulk fertilizer.
|
||
Use Method, Rate and Timing
|
||
Established Perennial Cool-season Forage Grasses.
|
||
Apply Prowl H2O to solid stands of perennial cool-season
|
||
forage grasses [including bentgrass, bluegrass (Kentucky),
|
||
bromegrass, fescue (fine, tall), orchardgrass, perennial rye -
|
||
grass, timothy, wheatgrass, and others] grown for forage,
|
||
green chop, silage, hay production, and/or grown in pas-
|
||
tures, rangeland, or Federal Conservation Reserve
|
||
Program (CRP) land for livestock grazing.
|
||
Apply Prowl H2O only to established (grass with 6 or
|
||
more tillers per plant) perennial cool-season forage
|
||
grasses.
|
||
Apply Prowl H2O before target-weed germination in fall
|
||
after the last cutting/mowing/grazing, in winter, in spring,
|
||
or in-season between cuttings.
|
||
Uniformly apply at a broadcast rate of 1.1 to 4.2 quarts of
|
||
Prowl H2O per acre in a single application or sequential
|
||
applications made 30 or more days apart.
|
||
DO NOT apply more than a maximum cumulative total of
|
||
4.2 quarts of Prowl H2O per acre per year.
|
||
Apply the higher rate of Prowl H2O when higher weed
|
||
pressure is anticipated or when a longer duration of resid -
|
||
ual weed control is desired.
|
||
Prowl H2O may cause temporary injury to cool-season
|
||
forage grass stands. Application made in periods of cold
|
||
temperatures that temporarily limit normal crop growth or
|
||
in extended cold temperature periods that initiate winter
|
||
dormancy in grass crops may result in crop injury. Disease,
|
||
extremely cold weather, drought, extensive frost heaving,
|
||
salinity, low pH, or high pH may weaken stands and make
|
||
the crop more susceptible to herbicide injury.
|
||
Mixed Stands of Established Cool-season Forage
|
||
Grasses and Alfalfa. Apply Prowl H2O to mixed stands
|
||
of established cool-season forage grasses and alfalfa
|
||
(established alfalfa is defined as alfalfa planted in fall or
|
||
spring which has gone through a first cutting/mowing).
|
||
Apply Prowl H2O in fall after the last cutting/mowing/
|
||
grazing, in winter, in spring before weed germination, or
|
||
in-season between cuttings.
|
||
Chemigation Application
|
||
Prowl H2O may be applied through sprinkler irrigation
|
||
systems. Follow all directions, special instructions, and
|
||
restrictions about chemigation in the Application
|
||
Instructions section of this label.
|
||
Tank Mixes
|
||
Prowl H2O may be applied in a sequential use program
|
||
with other herbicides labeled for use in cool-season forage
|
||
grasses or applied as a tank mix with other registered her-
|
||
bicides that control emerged weeds. Application of
|
||
postemergence herbicides may cause crop injury. BASF
|
||
recommends testing Prowl H2O tank mixes on a small
|
||
portion of the target crop to determine if damage is likely to

State-specific Instructions
|
||
Idaho, Montana, North Dakota, Oregon, and
|
||
Washington
|
||
Prowl H2O may be applied to lentil or peas (dry peas only)
|
||
grown in no-tillage and/or minimum-tillage systems in
|
||
Idaho, Montana, North Dakota, Oregon, and Washington.
|
||
Preplant surface application must be made within 30 days
|
||
of planting. When planting, ensure the seed furrow is fully
|
||
closed because conditions that allow the seed furrow to
|
||
inadequately close and/or allow Prowl H2O to contact the
|
||
seed may result in crop injury. Certain unfavorable environ -
|
||
mental conditions, including cool temperatures, excessive
|
||
moisture after application, and wet and/or compacted soil
|
||
conditions, may result in delayed emergence and stunting
|
||
with Prowl H2O use in lentil or peas. Adequate rainfall or
|
||
irrigation after application before weed seedling germina -
|
||
tion provides the most effective weed control. Herbicide
|
||
performance from surface application may be decreased
|
||
compared to soil incorporated application.
|
||
Idaho, Oregon, and Washington
|
||
Prowl H2O may be applied postplant preemergence only
|
||
to lentil or all peas grown in conventional-tillage systems in
|
||
Idaho, Oregon, and Washington. Application must be
|
||
made within 2 days of planting. Apply up to but not more
|
||
than 1.5 pts/A. Apply to a firm seedbed free of clods. Soil
|
||
conditions that cause poor seed furrow closure and cover-
|
||
age may result in delayed emergence and stunting of the
|
||
crop. Certain environmental conditions including cool tem -
|
||
peratures, excessive moisture after application, and wet
|
||
soil conditions may result in delayed emergence and stunt -
|
||
ing with Prowl H2O use in lentil or peas. Adequate rainfall
|
||
or irrigation after application before weed seedling germi -
|
||
nation provides the most effective weed control.
|
||

Make a single broadcast preemergence application of
|
||
Prowl H2O at 1.5 pints to 4.0 pints per acre, depending
|
||
on soil texture (see chart following), to dormant established
|
||
mint before weed germination. After Prowl H2O applica-
|
||
tion, temporary crop injury may be observed early in the
|
||
|

|
||
growing season as mint breaks dormancy and begins to
|
||
grow.
|
||
Prowl® H2O herbicide will not cause crop injury when
|
||
applied a ccording to the label under normal growing con -
|
||
ditions. Nonuniform application may result in injury to
|
||
crops, poor stands, or soil residues; conversely, uneven
|
||
application may reduce weed control. Diseases, cold
|
||
weather, excessive moisture, deep planting, low or high
|
||
pH, salinity, or drought may weaken seedlings and plants
|
||
and make them more susceptible to herbicide damage.

Crop-specific Restrictions
|
||
• DO NOT apply Prowl H2O to mint in the first year of
|
||
growth and establishment.
|
||
• DO NOT apply to mint that has broken dormancy or
|
||
crop injury may result. Application to mint near dormancy
|
||
break can result in crop injury. Risk of crop injury
|
||
increases the closer application is to mint dormancy
|
||
break.
|
||
• DO NOT apply to mint stands that have been weakened
|
||
by age, disease, cold weather, excessive moisture, or
|
||
other factors that reduce crop vigor. Mint growing under
|
||
stress is more susceptible to herbicide damage.
|
||
• DO NOT apply more than 4.0 pints per acre per year.
|
||
• Preharvest Interval (PHI) - 90 days
|
||
• DO NOT allow livestock to graze on treated spent hay or
|
||
feed treated spent hay to livestock.
|
||
• DO NOT apply this product on mint through any type of
|
||
irrigation system.
|

Monarda
|
||
Prowl H2O may be applied by ground, air, chemigation, or
|
||
on dry bulk fertilizer.
|
||
Use Method, Rate, and Timing
|
||
Before weed germination, make a broadcast application of
|
||
Prowl H2O at 1.5 pints to 4.0 pints per acre, depending
|
||
on soil texture (see chart following), to established monar-
|
||
da in dormancy, after emergence in the spring, or after the
|
||
first harvest. After Prowl H2O herbicide application, tem-
|
||
porary crop injury may be observed during the growing
|
||
season as monarda breaks dormancy and begins to grow,
|
||
or re-grows after harvest.
|
||
Prowl H2O will not cause crop injury when applied
|
||
according to the label under normal growing conditions.
|
||
Nonuniform application may result in injury to crops, poor
|
||
stands, or soil residues; conversely, uneven application
|
||
may reduce weed control. Diseases, cold weather, exces-
|
||
sive moisture, deep planting, low or high pH, salinity, or
|
||
drought may weaken seedlings and plants and make them
|
||
more susceptible to herbicide damage.

|
||
• DO NOT apply to monarda stand that have been weak-
|

Perennial Grasses
|
||
Grown for Seed Production
|
||
Prowl H2O may be applied to established (defined as
|
||
planted in the fall or spring which has gone through a first
|
||
cutting/mowing) warm-season perennial grasses (including
|
||
Bermudagrass, switchgrass, and others) and to estab-
|
||
lished (6 or more tillers per plant) cool-season perennial
|
||
grasses (including Kentucky bluegrass, tall fescue,
|
||
orchardgrass, perennial ryegrass, fine fescue, and others).
|
||
Prowl H2O may be applied by ground, chemigation, air, or
|
||
on dry bulk fertilizer.
|
||
Use Method, Rate, and Timing
|
||
In warm-season perennial grasses, apply Prowl H2O to
|
||
postharvest grass during the fall or during winter dorman -
|
||
cy or after the first seed harvest/cutting. DO NOT apply to
|
||
warm-season perennial grasses after greenup in the spring
|
||
before the first seed harvest/cutting. In cool-season peren -
|
||
nial grasses, apply Prowl H2O to postharvest grass
|
||
during regrowth at the beginning of significant fall rains or
|
||
in spring.
|
||
Apply Prowl H2O before target-weed germination. Uni-
|
||
formly apply at a broadcast rate of 2.1 to 4.2 quarts of
|
||
Prowl H2O per acre in a single application. Prowl H2O
|
||
may also be applied in two split applications, with 1/2 the
|
||
annual application rate applied in fall or winter followed by
|
||
the remaining 1/2 of the annual application rate applied in
|
||
spring. DO NOT apply more than a maximum cumulative
|
||
total of 4.2 quarts of Prowl H2O per acre in any one year.
|
||
In warm-season and cool-season perennial grasses, use
|
||
the high application rate of Prowl H2O where more dense
|
||
infestations of targeted annual grasses, annual broadleaf
|
||
weeds, or volunteer grass seedlings are anti cipated, or
|
||
when a longer duration of residual weed control is desired.
|
||
Excess grass straw and crop residue from the previous
|
||
harvest must be evenly spread or removed by such meth -
|
||
ods as crew cutting, propane flaming, or open field
|
||
burning (when local regulations allow) before Prowl H2O
|
||
application, or reduced weed control may result.
|
||
Prowl H2O may be applied in a sequential use program or
|
||
as a tank mix with other registered herbicides that control
|
||
emerged weeds.
|
||
Prowl H2O may cause temporary injury to perennial grass
|
||
stands. Application made in periods of cold temperatures
|
||
that temporarily limit normal crop growth or in extended
|
||
cold temperature periods that initiate winter dormancy in
|
||
grass crops may result in crop injury. Diseases, extremely
|
||
cold weather, drought, extensive frost heaving, low or high
|
||
pH, or salinity may weaken stands and make them more
|
||
susceptible to herbicide damage.
|
||
Chemigation Application
|
||
Prowl H2O may be applied through sprinkler irrigation
|
||
systems. Follow all directions, special instructions, and
|
||
restrictions about chemigation in Application
|
||
Instructions section of this label.
|
||
Additional Weeds Controlled
|
||
Prowl H2O applied before weed germination controls
|
||
annual bluegrass, volunteer fescue, and volunteer ryegrass
|
||
in addition to weeds listed in Table 2 .
|
||
Tank Mixes
|
||
Prowl H2O may be tank mixed with Outlook® herbicide
|
||
(dimethenamid-p) or with other herbicides labeled for use
|
||
in perennial grasses grown for seed. BASF recommends
|
||
testing Prowl H2O tank mixes on a small portion of the
|
||
target crop to determine if damage is likely to occur.
|
||
Physical incompatibility, reduced weed control, or
|
||
crop injury may result from mixing Prowl H2O with
|
||
other pesticides, additives, or ferti lizers.
|
||
Application of postemergence herbicides may cause crop
|
||
injury. Consult your local BASF dealer regarding local tank
|
||
mix options. Always perform a mixing test to check the
|
||
compatibility of Prowl H2O with all potential tank mix part-
|
||
ners. Follow all precautions and restrictions on the labels
|
||
of all products applied in combination with Prowl H2O .
|
||
Always follow the most restrictive label.
|
||
Crop-specific Restrictions
|
||
• DO NOT apply if surface water is present in the field.
|
||
• DO NOT apply more than a maximum cumulative total of
|
||
4.2 quarts of Prowl H2O per acre in any one year.
|
||
• There is no preharvest interval for grass forage or hay, or
|
||
for livestock grazing after application of Prowl H2O
|
||
• Preharvest Interval (PHI) for seed of warm-season and
|
||
cool-season perennial grasses - 90 days
|
||
• Not for use in California except as directed in supple-
|
||
mental labeling.
|
||
Crop-specific Precautions
|
||
• Some stunting and chlorosis of perennial grasses
|
||
may occur with postemergence application.
|
||
• Application made after perennial grasses exceed
|
||
6 inches in height may result in poor weed control
|
||
because of possible reduced spray coverage to
|
||
the soil.
|
||
• Grass straw remaining after seed harvest of
|
||
warm-season and cool-season perennial grasses may
|
||
be used as livestock bedding, and/or grazed by or fed to
|
||
livestock. The grower must notify the seed processor
|
||
that there is no pesticide tolerance on grass seed
|
||
screenings; therefore, it cannot be used in livestock feed.

|
||
potatoes and weeds emerge. Take care incorporation
|
||
equipment does not damage seed pieces or elongating
|

|
||
Rice
|
||
Prowl H2O may be applied by ground, air, or on dry bulk
|
||
fertilizer (delayed preemergence and early postemergence
|
||
applications only) to rice grown under conventional-tillage,
|
||
reduced-tillage, minimum-tillage, or no-till systems, or on
|
||
stale seedbeds.
|
||
Additional Weeds Controlled. In addition to weeds list-
|
||
ed in Table 2 , Prowl H2O controls the following weeds in
|
||
rice: junglerice and sprangletop.
|
||
Use Method, Rate, and Timing
|
||
Delayed Preemergence. Apply Prowl H2O alone or
|
||
with tank mix partner for delayed preemergence weed
|
||
control in grain-drilled, dry-seeded rice. Apply Prowl H2O
|
||
alone or in tank mix to levees after the levees are pulled
|
||
and planted. The seedbed needs to be firm and free of
|
||
clods and must be prepared to allow for good seed cover-
|
||
age. Use of a planter under conditions that do not allow
|
||
good soil coverage of the rice seed can result in reduced
|
||
stand or stunting if Prowl H2O contacts germinating rice
|
||
seed. Exposed seeds that come in contact with
|
||
Prowl H2O may be injured. Apply only when growing con-
|
||
ditions favor vigorous rice growth. The seedbed should
|
||
have adequate moisture for seed germination. Not for use
|
||
in grain-drilled, dry-seeded rice in California.
|
||
Uniformly apply the specified rate of Prowl H2O after rice
|
||
planting and before rice emergence (spiking) and weed
|
||
germination. Apply after rice seed has absorbed water and
|
||
germinated and after the soil has been previously sealed
|
||
over the seed by at least 1 inch of rainfall or by irrigation
|
||
(flush). If the soil has not been sealed by rain or flush, apply
|
||
when 80 percent of germinated seeds have a primary root
|
||
(radicle) or shoot at least 1/2-inch long. If there is insuffi-
|
||
cient moisture, BASF recommends flushing before
|
||
Prowl H2O application to supply moisture for root (radicle)
|
||
initiation and for vigorous rice and weed growth.
|
||
If applied to soil before these conditions, or to cracked soil,
|
||
stand reduction or stunting of rice may occur. Under some
|
||
conditions, use of gibberellic acid-treated seed, heavy rain -
|
||
fall after application, or flushing after application may result
|
||
in herbicide injury to rice. Rice can overcome moderate
|
||
injury with appropriate cultural practices.
|
||
Because of the residual activity of Prowl H2O , this treat-
|
||
ment may be applied if rice is too small to maintain a flood
|
||
on the field for weed control. However, proper water man-
|
||
agement practices must be followed for normal rice
|
||
growth and activity of Prowl H2O .
|
||
Early Postemergence. Apply Prowl H2O as a tank mix
|
||
partner in dry-seeded rice. Base applications on weed and
|
||
crop size guidelines of the tank mix partner. DO NOT
|
||
apply to fields with standing water. If necessary, fields may
|
||
be flushed before treatment to produce vigorous rice and
|
||
weed growth. Because soil and weeds must be complete -
|
||
ly exposed to spray coverage, no flood water should be on
|
||
the field at the time of application. Cloddy soil, standing
|
||
water (puddles) at the time of application, or cracks in the
|
||
soil that form after application may result in reduced weed
|
||
|
||
35
|
||
control. Because of residual activity of Prowl® H2O
|
||
herbicide, this treatment may be applied if rice is too
|
||
small to maintain a flood on the field for weed control.
|
||
However, proper water management practices must be
|
||
followed for normal rice growth and activity of Prowl H2O .
|
||
Postemergence (California water-seeded rice only).
|
||
As a component of a comprehensive weed management
|
||
program, apply Prowl H2O alone or tank mixed with a
|
||
postemergence herbicide after water-seeded rice has
|
||
reached the 4-leaf to 6-leaf stage (spike plus 3 to 5 true
|
||
leaves). Applications made before the 4-leaf rice stage may
|
||
result in crop injury.
|
||
Water-seeded rice must also be well-rooted/pegged
|
||
(i.e. standing erect after the flood is removed) before appli -
|
||
cation. DO NOT apply to rice that is leaning over and/or
|
||
laying flat to the ground after flood removal since this is
|
||
characteristic of a poorly established root system. Rice
|
||
roots must be below the Prowl H2O -treated soil zone.
|
||
Injury, stunting, and/or stand reduction can occur if
|
||
Prowl H2O contacts the rice roots.
|
||
Fields must be completely drained and free of standing
|
||
water (moist/saturated soil) before application. If soil is
|
||
saturated at the time of application, allow the soil surface
|
||
to dry before restoring the permanent flood. Prowl H2O
|
||
requires alternate wetting/drying cycles to be activated.
|
||
Weed control will be reduced if the soil surface is not
|
||
allowed to dry out before restoration of the permanent
|
||
flood. Resume normal water management practices after
|
||
permanent flood restoration.
|
||
Prowl H2O does not control weeds postemergence;
|
||
therefore, Prowl H2O must be tank mixed with a
|
||
postemergence herbicide to control emerged weeds at the
|
||
time of application.
|
||
Prowl H2O aids in control or suppression of the following
|
||
weeds when used as part of a comprehensive weed man -
|
||
agement program:
|
||
Barnyardgrass, early and late watergrass (including bio -
|
||
types resistant to other herbicide modes of action, e.g. rice
|
||
mimic), sprangletop, smallflower umbrella sedge*, redstem*
|
||
* Suppression only
|
||
In California water-seeded rice, Prowl H2O may be
|
||
applied with aerial or ground application equipment. For
|
||
aerial application, apply the specified rate of Prowl H2O in
|
||
5 gallons to 10 gallons of water per acre. If applied as a
|
||
tank mix with another herbicide, make sure proper gal -
|
||
lonage per acre per label directions (i.e. 10 to 15 with
|
||
propanil) is used to ensure thorough coverage. To minimize
|
||
drift, DO NOT apply during periods of wind more than
|
||
10 mph, or when wind conditions favor drifting, or if there
|
||
is a temperature inversion. BASF recommends that a flag-
|
||
man or an automatic mechanical flagging unit on the
|
||
aircraft be used to avoid overlapping and possible crop
|
||
injury.
|
||
For ground equipment, apply the specified rate of
|
||
Prowl H2O in 10 gallons to 20 gallons of water per acre. If
|
||
Prowl H2O is applied as a tank mix with another
|
||
herbicide, make sure proper gallonage per acre per label
|
||
directions (i.e. 20 to 30 for propanil) is used to ensure thor-
|
||
ough coverage. Use a calibrated low-pressure (20 PSI to
|
||
40 PSI) sprayer equipped with appropriate nozzles for uni -
|
||
form spray distribution and minimize drift. Keep the bypass
|
||
line on or near the bottom of the tank to minimize foaming.
|
||
Nozzle screens must be no finer than 50 mesh. DO NOT
|
||
apply Prowl H2O during periods of gusty winds or when
|
||
wind velocity is more than 20 mph.
|
||
Postemergence Tank Mixes: To control emerged
|
||
weeds at application, Prowl H2O may be tank mixed with
|
||
one of the following postemergence herbicides:
|
||
bispyribac-sodium
|
||
cyhalofop
|
||
orthosulfamuron
|
||
penoxsulam
|
||
propanil
|
||
triclopyr
|
||
When using tank mixes with Prowl H2O , always read the
|
||
companion product label(s) and follow all precautions and
|
||
restrictions. Always follow the most restrictive label.
|
||
Observe all restrictions regarding propanil-restricted
|
||
zones.
|
||
Crop-specific Restrictions (for water-seeded rice)
|
||
• DO NOT apply Prowl H2O before the 4-leaf rice stage
|
||
(spike plus 3 true leaves) or to rice that is not well-rooted/
|
||
pegged. The rice must be standing erect after the flood
|
||
is removed and before application.
|
||
• DO NOT apply to fields with standing water.
|
||
• DO NOT apply Prowl H2O through any type of irrigation
|
||
system.
|
||
• DO NOT apply in liquid fertilizer.
|
||
• DO NOT spray target crop within 60 feet of sensitive
|
||
crops (crops not listed on the Prowl H2O label).
|
||
• DO NOT spray target crop within 60 feet of crops
|
||
labeled for Prowl H2O application where the method of
|
||
application, rate, or timing of spray application is
|
||
prohibited.
|
||
• DO NOT apply more than the maximum rate for any soil
|
||
type in one year.
|
||
• DO NOT use water containing Prowl H2O residues
|
||
from rice cultivation to irrigate food or feed crops not reg-
|
||
istered for use with Prowl H2O .
|
||
In case of a crop failure because of weather conditions or
|
||
disease after treatment with Prowl H2O alone or in tank
|
||
mix, only drilled dry-seeded rice may be immediately
|
||
replanted; however, the grower assumes all risks and con-
|
||
sequences associated with replanting of rice because
|
||
there is the potential for stand reduction or stunting. BASF
|
||
recommends a 10% increase in seeding rate. Replant
|
||
seed below the herbicide layer because reduced stand or
|
||
stunting may occur if Prowl H2O contacts germinating
|
||
rice seed. DO NOT replant gibberellic acid-treated seed.
|
||
DO NOT reapply Prowl H2O alone or in tank mix.
|
||
DO NOT apply to stressed rice. Stress factors include cold
|
||
or hot temperature extremes, excessive moisture or
|
||
|
||
36
|
||
drought, problem soils, poor field drainage, or deep water

Crop-specific Restrictions
|
||
• DO NOT apply Prowl® H2O herbicide through any
|
||
type of irrigation system.
|
||
• DO NOT apply in liquid fertilizer.
|
||
• DO NOT use on water-seeded rice except as specified
|
||
in other BASF labeling.
|
||
• DO NOT apply to rice fields if fields are used for fish pro -
|
||
duction, especially catfish farming.
|
||
• Prowl H2O may be applied to rice fields used for cray-
|
||
fish production.
|
||
• DO NOT use water containing Prowl H2O residue from
|
||
rice cultivation to irrigate food or feed crops not regis-
|
||
tered for use with Prowl H2O .
|
||
• In case of crop failure because of weather conditions or
|
||
disease after treatment with Prowl H2O alone or in tank
|
||
mix, only drilled dry-seeded rice may be immediately
|
||
replanted; however, the grower assumes all risks and
|
||
consequences associated with replanting of rice
|
||
because there is the potential for stand reduction or
|
||
stunting. BASF recommends a 10% increase in seeding
|
||
rate. Replant seed below the herbicide layer because
|
||
reduced stand or stunting may occur if Prowl H2O con-
|
||
tacts germinating rice seed. DO NOT replant with
|
||
gibberellic acid-treated seed. DO NOT reapply
|
||
Prowl H2O alone or in tank mix.
|
||
• DO NOT apply Prowl H2O and then flush for
|
||
germination.
|
||
• DO NOT apply to stressed rice. Stress factors include
|
||
cold or hot temperature extremes, excessive moisture or
|
||
drought, problem soils, poor field drainage, or deep
|
||
water after application.
|
||
• DO NOT apply early preemergence or preplant incorpo -
|
||
rated because severe rice injury is possible.
|
||
Rosemary
|
||
Prowl H2O may be applied by ground, air, chemigation, or
|
||
on dry bulk fertilizer.
|
||
Use Method, Rate, and Timing
|
||
Before weed germination, make a broadcast application of
|
||
Prowl H2O at 1.5 pints to 4.0 pints per acre, depending
|
||
on soil texture (see chart following), to established rose-
|
||
mary prior to onset of rapid growth in early spring or after
|
||
the first harvest. After Prowl H2O herbicide application,
|
||
temporary crop injury may be observed during the growing
|
||
season as rosemary grows or re-grows after harvest.
|
||
Prowl H2O will not cause crop injury when applied
|
||
according to the label under normal growing conditions.
|
||
Nonuniform application may result in injury to crops, poor
|
||
stands, or soil residues; conversely, uneven application
|
||
may reduce weed control. Diseases, cold weather, exces-
|
||
sive moisture, deep planting, low or high pH, salinity, or
|
||
drought may weaken seedlings and plants and make them
|
||
more susceptible to herbicide damage.

Crop-specific Restrictions
|
||
• DO NOT apply Prowl H2O to rosemary in the first year
|
||
of growth and establishment.
|
||
• DO NOT apply to rosemary stand that have been weak-
|
||
ened by age, disease, cold weather, excessive moisture,
|
||
or other factors that reduce crop vigor, as rosemary
|
||
growing under stress is more susceptible to herbicide
|
||
damage.
|
||
• DO NOT apply more than 4.0 pts (1.9 lbs pendimethalin)
|
||
of Prowl H2O per acre per year.
|
||
• Preharvest Interval (PHI) – 60 days
|
||
• DO NOT allow livestock to graze on treated spent hay or
|
||
feed treated spent hay to livestock.
|
||
Crop-specific Precautions
|
||
• Avoid overlapping spray patterns because crop injury
|
||
can occur.
|
||
|
||
37
|
||
• Avoid heavy residue on soil surface from previous year’s
|
||
crops.
|
||
Safflower
|
||
Prowl® H2O herbicide may be applied to safflower by
|
||
ground, air, or on dry bulk fertilizer (only fall and preplant
|
||
incorporated applications).
|
||
Plant safflower 1-1/2 inches to 2-inches deep and
|
||
completely cover with soil. In California, plant
|
||
safflower deep enough to completely cover with
|
||
soil.
|
||
Use Method, Rate, and Timing
|
||
Preplant Incorporated. In all states, apply within 60 days
|
||
of planting and incorporate.
|
||
Preplant Incorporated
|
||
Fall Application in Minnesota, Montana, North
|
||
Dakota, and South Dakota. Apply Prowl H2O and
|
||
immediately incorporate in late fall before planting safflower
|
||
the following spring. Apply Prowl H2O in the late fall when
|
||
soil temperatures are 45° F or below but before the ground
|
||
freezes. DO NOT apply when air temperature is below
|
||
45º F. Before safflower planting in the spring, fields treated
|
||
with Prowl H2O must receive at least one shallow addi-
|
||
tional incorporation. Spring incorporation must be at an
|
||
angle to the last tillage operation.
|
||
Fall Application in California. Apply Prowl H2O and
|
||
immediately incorporate during tillage operations in the fall
|
||
to target winter annual weeds before planting safflower the
|
||
following spring. Before safflower planting in the spring,
|
||
fields treated with Prowl H2O must receive at least one
|
||
additional incorporation.
|
||
Preemergence. Apply Prowl H2O at planting or up to
|
||
2 days after planting.
|
||
Preemergence application of Prowl H2O to safflower may
|
||
increase the likelihood of crop injury, especially when
|
||
crops are grown in stress situations, including compacted
|
||
soils. Decreased herbicide performance compared to pre -
|
||
plant incorporated application may also result from a
|
||
preemergence application. If dry conditions with limited
|
||
precipitation exist or unseasonably cool temperatures after
|
||
planting are forecast, apply Prowl H2O before planting
|
||
and mechanically incorporate with tillage. Prowl H2O may
|
||
be applied preemergence in conventional- tillage safflower.
|
||
Preemergence application of Prowl H2O to safflower
|
||
grown in California must be followed with irrigation or rain -
|
||
fall to establish a crop stand.
|
||
No-till Safflower. Prowl H2O may be applied at

Use Method, Rate, and Timing
|
||
Stunting, reduced growth, or reduction in daughter
|
||
plants may occur with use of Prowl H2O in
|
||
strawberries and other low-growing berries.
|
||
Uniformly apply 1.5 to 3.0 pints per acre of Prowl H2O as
|
||
a broadcast spray to the soil surface at pretransplant time
|
||
or post-transplant time (must be within 7 days of trans-
|
||
planting of rootstock in the Pacific Northwest). However, in
|
||
areas where irrigation is used daily (frequently) after trans -
|
||
planting, apply Prowl H2O just before the end of the
|
||
watering regime to maximize weed control benefits of
|
||
Prowl H2O . Extended periods of irrigation may reduce
|
||
residual control provided by Prowl H2O .
|
||
However, Prowl H2O applications to row middles
|
||
between the beds are allowed. DO NOT apply post-
|
||
transplant if new foliage from rootstock is exposed to spray
|
||
area. A second application of 1.5 to 3.0 pints per acre of
|
||
Prowl H2O may be applied in a band to the soil between
|
||
crop rows (or between the plastic beds) 35 days before
|
||
harvest, but DO NOT CONCENTRATE THE RATE per
|
||
acre into the treated area, and DO NOT allow spray to
|
||
contact strawberry or other low-growing berry plants. The
|
||
second application rate is based on per unit of treated
|
||
area.
|
||
Prowl H2O may also be applied to strawberries or other
|
||
low-growing berries in fall or winter dormancy. Uniformly
|
||
apply 1.5 to 3.0 pints per acre of Prowl H2O as a broad-
|
||
cast spray to the soil surface before onset of new seasonal
|
||
growth from strawberry or other low-growing berry
|
||
crowns. DO NOT apply if new seasonal growth (leaves)
|
||
has emerged or is exposed.
|
||
Prowl H2O may also be applied to perennial strawberries
|
||
or other low-growing berries after renovation. Uniformly
|
||
apply 1.5 to 3.0 pints per acre of Prowl H2O as a broad-
|
||
cast spray to the soil surface after renovation (mowing or
|
||
other defoliation operation) when no foliage is exposed but
|
||
before onset of new seasonal growth from strawberry or
|
||
other low-growing berry crowns. DO NOT apply if new
|
||
seasonal growth (leaves) has emerged or leaves are
|
||
exposed.
|
||
Chemigation Application

|
||
or 3-inches deep. A minimum interval of 60 days between
|
||
Prowl H2O application and planting of sugarcane is
|
||
required or crop injury may occur. After planting, apply
|
||
Prowl H2O to sugarcane preemergence through layby,
|
||
but DO NOT apply more than 12.5 pts/A of Prowl H2O
|
||
during one year.

with postemergence herbicides and/or mechanical
|
||
cultivation.
|
||
Apply Prowl H2O at 2.6 to 3.5 qts/A using ground equip-
|
||
ment. DO NOT apply Prowl H2O below the high water
|
||
mark or when water is present in the drainage area (ditch-
|
||
bank). DO NOT apply more than 12.5 pts/A of Prowl H2O
|
||
during one year.
|
||
Areas in Hawaii Subject to High Winds. For wind
|
||
speeds between 10 to 20 mph, DO NOT apply in a man-
|
||
ner that allows spray to drift from the application target
|
||
site. Use drift-mitigating measures, including lowering the
|
||
spray boom; use coarse spray according to ASAE 572
|
||
definition for standard nozzles; use hooded or shielded
|
||
sprayers; use spray drift retardants; or use any other mea-
|
||
sures known to control drift.
|
||
Crop-specific Restrictions
|
||
• DO NOT apply more than 12.5 pints of Prowl H2O per
|
||
acre in one year.
|
||
• DO NOT use less than 11 gallons of water as a carrier
|
||
when applying Prowl H2O for weed control.
|
||
• DO NOT make aerial application at close-in because
|
||
complete and uniform coverage cannot be obtained.
|
||
• DO NOT apply through any type of irrigation system.
|
||
• Preharvest Interval (PHI) - 90 days
|
||
• DO NOT graze treated fields or feed treated forage or
|
||
fodder to livestock.
|
||
Crop-specific Precautions
|
||
• Ratoon sugarcane must be lightly shaved in early spring
|
||
to remove the old stubble before incorporation over the
|
||
line of sugarcane is possible. Carefully adjust equipment
|
||
to incorporate without causing excessive damage to
|
||
emerging shoots.

Minnesota, North Dakota, and South Dakota). Apply
|
||
Prowl H2O and immediately incorporate in late fall before
|
||
planting sunflower or oilseeds the following spring. Apply
|
||
Prowl H2O in late fall when soil temperatures are 45° F or
|
||
below but before the ground freezes. DO NOT apply when
|
||
air temperature is below 45º F. Before sunflower or other
|
||
Group 20B oilseeds planting in the spring, fields treated
|
||
with Prowl H2O must receive at least one shallow addi-
|
||
tional incorporation. Spring incorporation must be at an

Wheat and Triticale
|
||
Prowl H2O may be applied by ground, air, chemigation, or
|
||
on dry bulk fertilizer (only delayed preemergence and
|
||
postemergence applications).
|
||
Prowl H2O may be applied preemergence, delayed
|
||
preemergence, or postemergence for weed control in
|
||
fall-seeded, winter-seeded, or spring-seeded wheat or
|
||
triticale.
|
||
Use Method, Rate, and Timing
|
||
Apply to a seedbed which is firm and free of clods and
|
||
trash. The seedbed MUST be prepared to ensure thor-
|
||
ough seed coverage by the soil and seed-to-soil contact.
|
||
Use high quality seed. When application of Prowl H2O is
|
||
intended to be made preemergence or delayed
|
||
preemergence, plant seed at least 1-inch deep to avoid
|
||
possible crop injury, but not too deep for proper germina -
|
||
tion. When application of Prowl H2O is intended to be
|
||
made postemergence, plant seed at least 1/2-inch to
|
||
1-inch deep to avoid crop injury.
|
||
Uniformly apply Prowl H2O preemergence, delayed
|
||
preemergence (after wheat or triticale seed has germinat -
|
||
ed), or postemergence from the 1st-leaf stage of wheat or
|
||
triticale until before the flag leaf is visible/emerged for weed
|
||
control. Apply Prowl H2O before weed germination.
|
||
Emerged weeds will not be controlled by this treatment.
|
||

|
||
For control of established weeds, Prowl® H2O herbicide
|
||
may be tank mixed with any postemergence herbicide reg -
|
||
istered for use in wheat or triticale. Prowl H2O provides
|
||
residual control of weeds listed in this label. Always per-
|
||
form a mixing test to check the compatibility of
|
||
Prowl H2O with all potential tank mix partners.

In wheat stubble, Prowl H2O may be applied in the fall,
|
||
spring, or early summer during the fallow period after
|
||
wheat harvest as a planned residual treatment to control
|
||
labeled broadleaf and grass weeds. Prowl H2O must be
|
||
applied with a tank mix partner (i.e. glyphosate) for control
|
||
of emerged weeds. There must be at least a 4-month
|
||
interval between a Prowl H2O fallow application and the
|
||
rotational planting of any fall-seeded cereal crop. Apply up
|
||
to, but DO NOT apply more than, 3 pints/A of Prowl H2O
|
||
in any fallow application. DO NOT make more than one
|
||
application of Prowl H2O during a single fallow period
|
||
before rotational planting of any fall-seeded cereal crops.
|
||
Follow rotational crop restrictions when planting a rotation-
|
||
al crop after a fallow application of Prowl H2O .
|
||
Crop-specific Restrictions
|
||
• DO NOT apply more than 3.0 pints/A of Prowl H2O per
|
||
year.
|
||
• Preharvest Interval (PHI) for grain and straw - 60 days
|
||
• Preharvest Interval (PHI) for hay - 28 days
|
||
• Preharvest Interval (PHI) for forage - 11 days
|
||
Crop-specific Precautions
|
||
NOTE: If loss of grain crop occurs, any crop registered for
|
||
Prowl H2O preplant incorporated use may be replanted
|
||
the same year without adverse effects. DO NOT replant
|
||
wheat or triticale.
