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).

|
||
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 your company’s website on your label, then please be aware that

the website becomes labeling under FIFRA and is subject to review by EPA. If the website is false or
|
||
misleading, the product will be considered to be misbranded and sale or distribution of the product is unlawful
|
||
under FIFRA section 12(a)(1)(E). 40 CFR § 156.10(a)(5) lists examples of statements the EPA may consider

|
||
Users should:
|
||
• Remove clothing/PPE immediately if pesticide gets
|
||
inside . Then wash thoroughly and put on clean cloth-
|
||
ing . If pesticide gets on skin, wash immediately with
|
||
soap and water .

||
Environmental Hazards
|
||
DO NOT apply directly to water, areas where surface
|
||
water is present, or intertidal areas below the mean high
|
||
water mark . DO NOT contaminate water when disposing
|
||
of equipment washwater or rinsate . Drift and runoff may be
|
||
hazardous to aquatic organisms in water adjacent to treat-
|
||
ed areas .
|
||
Groundwater Advisory. Saflufenacil and pyroxasulfone
|
||
have properties and characteristics associated with chemi -
|
||
cals detected in groundwater . These chemicals may leach
|
||
into groundwater if used in areas where soils are perme -
|
||
able, particularly where the water table is shallow .
|
||
FIRST AID
|
||
If swallowed
|
||
• Call a poison control center or doctor immediately for treatment advice .
|
||
• DO NOT induce vomiting unless told to by a poison control center or doctor .
|
||
• Have a person sip a glass of water if able to swallow .

|
||
Surface Water Advisory. This product may impact sur-
|
||
face water quality due to runoff of rainwater . This is
|
||
especially true for poorly draining soils and soils with shal -
|
||
low groundwater . This product is classified as having high
|
||
potential for reaching surface water via runoff for several
|
||
months or more after application . A level, well-maintained
|
||
buffer strip between areas to which this product is applied
|
||
and surface water features including ponds, streams, and
|
||
springs will reduce the potential loading of saflufenacil,
|
||
pyroxasulfone, and pyroxasulfone’s degradation product,
|
||
[5-(difluoromethoxy)-1-methyl-3-(trifluoromethyl)-1H-
|
||
pyrazol-4-yl]methanesulfonic acid (M1), from runoff water
|
||
and sediment . Runoff of this product will be reduced by
|
||
avoiding application when rainfall is forecast to occur with -
|
||
in 48 hours .
|
||
Point-source Contamination. To prevent point-source
|
||
contamination, DO NOT mix or load this or any other pes-
|
||
ticide product within 50 feet of wells (including abandoned
|
||
wells and drainage wells), sinkholes, perennial or intermit-
|
||
tent streams and rivers, and natural or impounded lakes
|
||
and reservoirs . This setback does not apply to properly
|
||
capped or plugged abandoned wells and does not apply
|
||
to impervious pad or dike mixing/loading areas described
|
||
as follows .
|
||
Mixing, loading, rinsing, or washing operations performed
|
||
within 50 feet of a well are allowed only when conducted
|
||
on an impervious pad constructed to withstand the weight
|
||
of the heaviest load that may be on or move across the
|
||
pad . The pad must be self-contained to prevent surface
|
||
water flow over or from the pad . The pad capacity must be
|
||
maintained at 110% that of the largest pesticide container
|
||
or application equipment used on the pad and have suffi -
|
||
cient capacity to contain all product spills, equipment or
|
||
container leaks, equipment washwater, and rainwater that
|
||
may fall on the pad . The containment capacity does not
|
||
apply to vehicles delivering pesticide shipments to the mix -
|
||
ing and/or loading site . States may have in effect additional
|
||
requirements regarding wellhead setbacks and operational
|
||
containment .
|
||
Care must be taken when using this product to prevent:
|
||
• Back-siphoning into wells
|
||
• Spills
|
||
• Improper disposal of excess pesticide, spray mixes, or
|
||
rinsates
|
||
Check valves or anti-siphoning devices must be used on
|
||
all mixing equipment .

Product Information
|
||
SurtainTM herbicide provides rate-dependent residual
|
||
preemergence control of annual grass weeds, sedges, and
|
||
annual broadleaf weeds (including biotypes resistant to
|
||
ACCase inhibitors, ALS inhibitors, HPPD inhibitors, PSII
|
||
inhibitors, and glyphosate) (refer to Table 1 for list) . It can
|
||
be used in field corn (grain, seed, silage), fallow, and post-
|
||
harvest croplands .
|
||
Periods of dry weather following application of Surtain
|
||
may reduce herbicidal effectiveness . Residual
|
||
preemergence application of Surtain must be activated
|
||
by at least 1/2 inch of rainfall or sprinkler irrigation before
|
||
weed seedling emergence . When Surtain is not activated,
|
||
a labeled postemergence herbicide or cultivation may be
|
||
needed to control weed escapes . Surtain does not con-
|
||
trol emerged weeds .
|
||
Herbicidal activity of Surtain may be reduced if excessive
|
||
trash from the previous crop covers the soil surface during
|

1 Surtain must be used in tank mixes or sequential applications with other labeled herbicides that provide additional control of noted weeds .
|
||
Mode of Action
|
||
Surtain contains two active herbicide ingredients .
|
||
Saflufenacil is a potent inhibitor of protoporphyrin-
|
||
ogenoxidase belonging to herbicide mode-of-action
|
||
Group 14 . Pyroxasulfone is a potent inhibitor of very long
|
||
chain fatty acid (VLCFA) synthesis, belonging to herbicide
|
||
mode-of-action Group 15 . Saflufenacil is rapidly absorbed
|
||
by roots and foliage . Following inhibition of the
|
||
protoporphyrinogen-oxidase, plant death is the result of
|
||
membrane damage . Under active growing conditions, sus-
|
||
ceptible emerging weed seedlings usually develop
|
||
chlorotic and necrotic injury symptoms within hours and
|
||
die within a few days . Susceptible germinating weed seeds
|
||
usually die as they reach the soil surface or shortly after
|
||
emergence . Pyroxasulfone is a root-and-shoot inhibitor
|
||
that controls susceptible weed seedlings before or soon
|
||
after they emerge from the soil .
|
||
Herbicide Resistance Management
|
||
For resistance management, Surtain contains both a
|
||
Group 14 herbicide and Group 15 herbicide . Any weed
|
||
population may contain plants naturally resistant to
|
||
|
||
8
|
||
Group 14 and/or Group 15 herbicides . The resistant indi-
|
||
viduals may dominate the weed population if these
|
||
herbicides are used repeatedly in the same fields . Appropri-
|
||
ate resistant-management strategies should be followed .
|
||
To delay herbicide resistance consider:
|
||
• Avoiding the consecutive use of herbicides that have a
|
||
similar target-site-of-action on the same weed species .
|
||
• Using tank mixes or premixes with herbicides from
|
||
different target-site-of-action groups as long as the
|
||
involved products are all registered for the same use,
|
||
have different 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
|
||
(Integrated 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 .
|
||
• 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 partic-
|
||
ular weed species; or
|
||
3 . Surviving plants mixed with controlled individuals of
|
||
the same species .
|
||
• If resistance is suspected, treat weed escapes with a
|
||
herbicide with a different MOA and/or use non-chemical
|
||
methods to remove escapes, as practicable, with the
|
||
goal of preventing further seed production .
|
||
• Report any incidence of non-performance of this product
|
||
against a particular weed species to your 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 .
|
||
Crop Response
|
||
Crops listed on this label are tolerant to SurtainTM
|
||
herbicide when applied according to label directions and
|
||
under normal environmental conditions . Crop injury may
|
||
occur when application is made under stressful growing
|
||
conditions (e .g . mechanical injury, drought or excessive
|
||
moisture for normal crop development, extreme hot or
|
||
cold temperatures, widely fluctuating temperatures, seed -
|
||
ling disease, low soil fertility, high soil pH, high soil salt
|
||
concentration, or other pesticide injury) .
|
||
Application Instructions
|
||
Surtain may be applied before or after crop emergence .
|
||
Application Rate
|
||
Application rates of Surtain may vary depending on soil
|
||
texture and organic matter . Refer to Table 2 for soil texture
|
||
groups used in this label .

|
||
Application Timing
|
||
Surtain may be applied preplant surface, preplant incor-
|
||
porated, preemergence, or early postemergence . Refer to
|
||
the Crop-specific Information section for specific appli-
|
||
cation instructions (timings, rates, restrictions and
|
||
precautions) by crop .
|
||
Preplant Surface Application. Apply Surtain alone or
|
||
in tank mix within 30 days of planting . If weeds are present
|
||
at the time of application, use additional weed control
|
||
methods, for example a tank mix with an appropriate
|
||
postemergence herbicide(s), to control emerged weeds .
|
||
Preplant Incorporated (PPI) Application. Incorporate
|
||
Surtain into the upper (1 to 2 inches) soil surface within
|
||
14 days of planting . Deeper incorporation may increase the
|
||
potential for crop injury and also may result in reduced
|
||
weed control . Use appropriate equipment for uniform shal-
|
||
low incorporation, including a field cultivator, harrow, rolling
|
||
cultivator, or finishing disc .
|
||
Preemergence Surface Application. After planting and
|
||
before crop emergence, apply a uniform broadcast treat-
|
||
ment to the soil surface . Apply Surtain only to a uniform
|
||
seedbed which is firm and free of clods, cracks, excess
|
||
trash (previous crop residue), and weed growth . If weeds
|
||
are present, apply Surtain in a tank mix with an
|
||
|
||
9
|
||
appro priate postemergence herbicide, for example a
|
||
glyphosate-containing product .
|
||
Early Postemergence Application. SurtainTM
|
||
herbicide must be applied and activated before weed
|
||
seedling emergence or in a tank mixture that controls
|
||
emerged weeds . Surtain will not control emerged weeds .
|
||
Weeds that are already emerged at the time of application
|
||
must be controlled with cultivation, tank mix or sequential
|
||
application of another herbicide labeled for postemergence
|
||
control of the target weeds in the crop .
|
||
Application Methods and Equipment
|
||
Surtain may be applied by ground or air (fixed-wing air-
|
||
craft only, DO NOT apply by helicopter) .
|
||
Thorough spray coverage is required for optimum weed
|
||
control and can be improved with proper adjuvant, nozzle,
|
||
and spray volume selection . Use and configure application
|
||
equipment to provide an adequate spray volume, an accu-
|
||
rate and uniform distribution of spray droplets over the
|
||
treated area, and to avoid spray drift to nontarget areas .
|
||
Adjust equipment to maintain continuous agitation during
|
||
spraying with good mechanical or bypass agitation . Avoid
|
||
overlaps that increase rates above the use rates specified
|
||
in this label .
|
||
Surtain may be applied using water or sprayable fluid
|
||
nitrogen fertilizer solutions as the spray carrier . Additionally,
|
||
Surtain may be impregnated on and applied with dry bulk
|
||
fertilizer .
|
||
Aerial Spray Carrier Volume. Use 3 or more gallons of
|
||
water per acre . The actual minimum spray volume per acre
|
||
is determined by the spray equipment used . Use adequate
|
||
spray volume to provide accurate and uniform distribution
|
||
of spray particles over the treated area .
|
||
Ground Spray Carrier Volume. Use 3 or more gallons of
|
||
water per treated acre or 20 or more gallons of sprayable
|
||
fluid nitrogen fertilizer per treated acre .
|
||
Mandatory Spray Drift Management
|
||
Aerial Applications
|
||
• DO NOT release spray at a height greater than 10 ft
|
||
above the ground or crop canopy, unless a greater
|
||
application height is necessary for pilot safety .
|
||
• Applicators are required to select a nozzle and pres -
|
||
sure that deliver a medium or coarser droplet size
|
||
(ASABE S572) .
|
||
• When applying by airplane, use low-drift nozzles
|
||
(straight-stream nozzles, D-8 or larger) . DO NOT use
|
||
nozzles producing a mist droplet spray .
|
||
• The boom length must not exceed 75% of the wing-
|
||
span for airplanes .
|
||
• Applicators must use 1/2 swath displacement upwind
|
||
at the downwind edge of the field .
|
||
• Nozzles must be oriented so spray is directed towards
|
||
the back of the aircraft, parallel with the airstream, and
|
||
never point downward more than 45 degrees .

(continued)
|
||
Aerial Applications (continued)
|
||
• DO NOT apply when wind speeds exceed 10 mph at
|
||
the application site .
|
||
• DO NOT apply during temperature inversions .
|
||
Ground Applications
|
||
• Apply with the nozzle height recommended by the
|
||
manufacturer, but no more than 3 ft above the ground
|
||
or crop canopy .
|
||
• Applicators are required to select a nozzle and pres -
|
||
sure that deliver a medium or coarser droplet size
|
||
(ASABE S572) . Flood-jet type nozzles are recommend-
|
||
ed for residual soil surface application . Nozzles that
|
||
deliver coarse spray droplets may be used to reduce
|
||
spray drift provided spray volume per acre (GPA) is
|
||
increased to maintain coverage of target (i .e . soil sur-
|
||
face) . DO NOT use nozzles that produce fine
|
||
(e .g . cone) spray droplets .
|
||
• DO NOT apply when wind speeds exceed 10 mph at
|
||
the application site .
|
||
• DO NOT apply during temperature inversions .
|
||
Buffer Restrictions
|
||
Aerial Applications
|
||
To avoid potential adverse effects to nontarget areas,
|
||
applicators must maintain a 160-foot buffer between
|
||
the application area and the closest downwind edge
|
||
of nontarget terrestrial habitats (including grasslands,
|
||
forested areas, shelter belts, woodlots, hedgerows,
|
||
riparian areas, shrub lands, and crop lands) .
|
||
Ground Applications
|
||
To avoid potential adverse effects to nontarget areas,
|
||
applicators must maintain a 75-foot buffer between
|
||
the application area and the closest downwind edge
|
||
of nontarget terrestrial habitats (including grasslands,
|
||
forested areas, shelter belts, woodlots, hedgerows,
|
||
riparian areas, shrub lands, and crop lands) .
|
||
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
|
||
Volume. Increasing the spray volume so that larger drop-
|
||
lets are produced will reduce spray drift . Use the highest
|
||
practical spray volume for the application . If a greater spray
|
||
|
||
10
|
||
volume is needed, consider using a nozzle with a higher
|
||
flow rate .
|
||
Pressure. Use the lowest spray pressure recommended
|
||
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 manufacturers recommendations for setting
|
||
up nozzles . Generally, to reduce fine droplets, nozzles
|
||
must be oriented parallel with the airflow in flight .
|
||
Boom Height - Ground Boom
|
||
Use the lowest boom height that is compatible with the
|
||
spray nozzles that will provide uniform coverage . 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 .
|
||
When applying aerially to crops, DO NOT release spray at
|
||
a height greater than 10 feet above the crop canopy,
|
||
unless a greater application height is necessary for pilot
|
||
safety .
|
||
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 .
|
||
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 .
|
||
Ground Application (dry bulk fertilizer)
|
||
SurtainTM herbicide may be impregnated or coated onto
|
||
dry bulk granular fertilizer carriers for residual soil surface
|
||
application . Impregnation or coating may be conducted by
|
||
in-plant bulk or on-board systems . Perform the mixing
|
||
operation in well-ventilated areas .
|
||
Addition of a drying agent may be necessary if the fertilizer
|
||
and herbicide blend is too wet for uniform application
|
||
because of high humidity, high urea concentration, or low
|
||
fertilizer use rate . Slowly add the drying agent to the blend
|
||
until a flowable mixture is obtained . Drying agents are not
|
||
recommended for use with on-board impregnation
|
||
systems .
|
||
Under some conditions, fertilizer impregnated with Surtain
|
||
may clog air tubes or deflector plates on pneumatic appli -
|
||
cation systems . Mineral oil may be added to Surtain
|
||
before blending with fertilizer to reduce plugging . DO NOT
|
||
use drying agents when mineral oil is used . To avoid sepa-
|
||
ration of Surtain and mineral oil mixes in cold
|
||
temperatures, keep mixture heated or agitated before
|
||
blending with fertilizer . Mineral oil may be used at in-plant
|
||
blending stations or on-board injection systems .
|
||
Generally, fertilizer application rates of at least 200 lbs to
|
||
700 lbs per acre of herbicide and fertilizer blend provide
|
||
adequate distribution or coverage for Surtain across the
|
||
soil surface . Refer to Table 5 in this label for use rates of
|
||
Surtain to be applied on per acre basis when impregnat-
|
||
ed with fertilizer to create the dry bulk fertilizer blend for
|
||
application . Apply uniformly to the soil to prevent possible
|
||
crop injury and offer satisfactory weed control . Impregnat-
|
||
ed fertilizer spread at 1/2 rate and overlapped for a full rate
|
||
offer a more uniform distribution . Use shallow (less than
|
||
2 inches) incorporation for improved weed control . Deeper
|
||
incorporation dilutes the herbicide layer near the soil sur -
|
||
face and may result in unsatisfactory weed control .
|
||
To calculate the herbicide rate when using dry bulk fertiliz-
|
||
er applications:
|
||
fl ozs herbicide per acre x 2000 = fl ozs herbicide
|
||
per ton of fertilizerpounds fertilizer per acre
|
||
Cleaning Spray Equipment
|
||
Clean application equipment thoroughly by using a strong
|
||
detergent or commercial sprayer cleaner according to the
|
||
manufacturer’s directions, followed by triple rinsing the
|
||
equipment before and after applying this product .
|
||
Additives
|
||
Surtain is formulated to provide optimal residual pre-
|
||
emergence weed control . No additive is needed when
|
||
Surtain is applied alone .
|
||
However, several herbicide tank mixes with Surtain may
|
||
require an adjuvant to improve burndown of emerged
|
||
weeds . Therefore, depending on the timing of application
|
||
relative to crop emergence, the following adjuvants may be
|
||
used with Surtain tank mixes:
|
||
For applications made before crop emergence (i .e ., pre-
|
||
plant surface, preplant incorporated, or preemergence):
|
||
non-ionic surfactant (NIS), crop oil concentrate (COC), high
|
||
surfactant petroleum oil concentrate/blends (HSPOC),
|
||
methylated seed oil (MSO), high surfactant methylated oil
|
||
concentrate (HSMOC), urea ammonium nitrate (UAN) .
|
||
|
||
11
|
||
For applications made after crop emergence (i .e ., early
|
||
postemergence): NIS at 0 .25% v/v (1 qt/100 gal) optionally
|
||
with a spray grade ammonium sulfate (AMS) at 8 .5 to
|
||
17 lbs/100 gallons of water . If using liquid AMS product,
|
||
use a rate that delivers an AMS equivalent of 8 .5 to
|
||
17 lbs/100 gallons of water . The use of COC or HSPOC
|
||
may result in temporary crop injury . DO NOT add MSO or
|
||
HSMOC or UAN to a SurtainTM herbicide spray mix .
|
||
When an adjuvant is to be used with this product, BASF
|
||
recommends the use of a Chemical Producers and
|
||
Distributors Association (CPDA) certified adjuvant .
|
||
DO NOT add acidifying agents to the spray tank when
|
||
applying Surtain .
|
||
Tank Mixing Information
|
||
It is the pesticide user’s responsibility to ensure that all
|
||
products in the mixtures are registered for the intended
|
||
use . Read and follow the applicable restrictions and limita -
|
||
tions and directions for use on all product labels involved in
|
||
tank mixing . Users must follow the most restrictive direc-
|
||
tions for use and precautionary statements of each
|
||
product in the tank mixture .
|
||
Surtain 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 applica -
|
||
tion instructions, use restrictions and precau tions, and
|
||
rotational cropping guidance .
|
||
Compatibility Test for Mix Components
|
||
Before mixing components, always perform a compatibility
|
||
jar test .
|
||
1 . For 20 gallons per acre spray volume, use 3 .3 cups
|
||
(800 mL) of water . For other spray volumes, adjust rates
|
||
accordingly . Only use water from the intended source at
|
||
the source temperature .
|
||
2 . Add components in the sequence indicated in the
|
||
Mixing Order section using 2 teaspoons for each
|
||
pound or 1 teaspoon for each pint of labeled use rate
|
||
per acre .
|
||
3 . Always cap the jar and invert 10 cycles between com-
|
||
ponent additions .
|
||
4 . When the components have all been added to the jar,
|
||
let the solution stand for 15 minutes .
|
||
5 . Evaluate the solution for uniformity and stability . The
|
||
spray solution must not have free oil on the surface, or
|
||
fine particles that precipitate to the bottom, or thick
|
||
(clabbered) texture . If the spray solution is not compati-
|
||
ble, repeat the compatibility test with the addition of a
|
||
suitable compatibility agent . If the solution is then com-
|
||
patible, use the compatibility agent as directed on its
|
||
label . If the solution is still incompatible, DO NOT mix
|
||
the ingredients in the same tank .
|
||
Mixing Order
|
||
Maintain constant agitation throughout mixing and applica -
|
||
tion until spraying is completed .
|
||
1 . Water - Fill tank 1/2 to 3/4 full with clean water and start
|
||
agitation .
|
||
2 . Inductor - If an inductor is used, rinse it thoroughly
|
||
after each component has been added .
|
||
3 . Products in PVA bags - Place any product contained
|
||
in water-soluble PVA bags into the mixing tank . Wait
|
||
until all water-soluble PVA bags have fully dissolved and
|
||
the product is evenly mixed in the spray tank before
|
||
continuing .
|
||
4 . Products that are formulated as Wettable
|
||
Powders, Dry Flowables, and Water Dispersible
|
||
Granules - Add to tank and allow to fully dissolve .
|
||
5 . Water-soluble additives (including dry and liquid fer-
|
||
tilizers AMS or UAN)
|
||
6 . Surtain - Add at this point in tank mix preparation
|
||
process .
|
||
7 . Water-dispersible liquid products (suspension con-
|
||
centrates and suspo-emulsions, including atrazine-,
|
||
mesotrione-, topramezone-based products)
|
||
8 . Water-soluble products (including certain glyphosate
|
||
formulated products)
|
||
9 . Emulsifiable Concentrates
|
||
10 . Adjuvants (including NIS, COC/HSPOC, MSO/HSMOC)
|
||
11 . Remaining quantity of water
|
||
If the spray mixture is allowed to settle for any period of
|
||
time, thorough agitation is essential to resuspend spray
|
||
mixture before spraying is resumed . Continue agitation
|
||
while spraying .
|
||

|
||
preplant incorporated, preemergence, or early post -
|
||
emergence to corn for residual preemergence control of
|
||
listed weeds (Table 1 ) . Corn in this label refers to field corn
|
||
(grown for grain, seed, or silage) . Before applying Surtain
|
||
to seed corn, verify the selectivity of Surtain on your

|
||
Application Timing
|
||
Surtain may be applied in a single application or in
|
||
sequential applications .
|
||
Early Preplant Surface Application
|
||
(within 15 to 30 days of planting)
|
||
Use application rates in Table 5 when making early pre-
|
||
plant surface applications, using the highest application
|
||
rate for a given soil texture . Early preplant surface applica-
|
||
tions are not advised on coarse soils, or in areas where
|
||
average annual rainfall (or rainfall plus irrigation) typically
|
||
exceeds 40 inches .
|
||
Early preplant surface applications may be applied as part
|
||
of a split application program where applications are made
|
||
as part of the application timings described in this label .
|
||
However, the cumulative total of sequential application
|
||
rates must not exceed the maximum labeled rate for a
|
||
given soil texture .
|
||
Preplant Surface and
|
||
Preplant Incorporated Application
|
||
(within 14 days of planting)
|
||
Apply Surtain at use rates specified in Table 5 as a
|
||
broadcast spray to the soil surface or incorporated before
|
||
planting on all soil types .
|
||
Preemergence Surface Application
|
||
Apply Surtain at use rates specified in Table 5 as a
|
||
broadcast spray to the soil surface after planting and
|
||
before crop emergence .
|
||
Early Postemergence Application
|
||
Apply Surtain at use rates specified in Table 5 as a broad-
|
||
cast spray to field corn at spiking up to the V3 stage (visible
|
||
third leaf collar) [Alternate text: V1 stage (visible first leaf col-
|
||
lar) or V2 stage (visible second leaf collar) or V4 stage (visible
|
||
fourth leaf collar) or V5 stage (visible fifth leaf collar) or
|
||
V6 stage (visible sixth leaf collar) or V8 stage (visible eighth
|
||
leaf collar)] .
|
||
Refer to Additives section for details about adjuvants for
|
||
applications of Surtain made after crop emergence .
|
||
Sequential Application
|
||
If a sequential application program of Surtain is used (e .g .
|
||
preplant followed by preemeergence application, or
|
||
preplant or preemergence followed by an early postemer-
|
||
gence application), the maximum combined rate of
|
||
Surtain that may be applied in field corn per year is
|
||
27 .0 fl ozs/A .
|
||
Crop-specific Use in Seed Corn. Apply Surtain pre-
|
||
plant surface, preplant incorporated, preemergence, or
|
||
early postemergence at 9 .2 fl ozs/A in seed corn across all
|
||
soil types . Sequential applications of Surtain may be
|
||
made with a minimum of 30 days between applications .
|
||
DO NOT apply more than a maximum cumulative amount
|
||
of 17 .0 fl ozs/A of Surtain per cropping season in seed
|
||
corn . Before applying Surtain to seed corn, verify the
|
||
selectivity of Surtain on your inbred line or hybrid with
|
||
|
||
14
|
||
your local seed company (supplier) to help avoid potential
|
||
injury to sensitive inbreds or hybrids .

plant surface, preplant incorporated, or preemergence
|
||
application of Surtain and the harvest of field corn . Corn
|
||
forage and stover may be fed to livestock after harvest .
|
||
• There is no required (preharvest or grazing) interval
|
||
between an early postemergence application of Surtain
|
||
made to field corn at V4 stage or earlier and the harvest
|
||
of field corn . Corn forage and stover may be fed to live-
|
||
stock after harvest .
|
||
• Pre-harvest and Pregrazing Interval (PHI, PGI) for
|
||
corn forage and stover with an early postemergence
|
||
application of Surtain made to field corn at V5 to
|
||
V8 stage = 30 days .
|
||
• DO NOT apply Surtain where an at- planting application
|
||
of an organophosphate or carbamate insecticide(s) is
|
||
planned and/or has occurred because severe injury may
|
||
result . Surtain may be applied with all other classes of
|
||
at-planting insecticides including neonicotinoids and
|
||
pyrethoids .
|
||
EXCEPTION: Surtain may be applied when
|
||
Aztec® 2.1% Granular Insecticide , AZTEC® 4.67 G
|
||
granular insecticide , or SmartChoice ® 5G granular
|
||
insecticide is applied at planting as a band, T-band, or
|
||
infurrow .
|
||
Crop-specific Precautions
|
||
• When applied before crop emergence, Surtain applica-
|
||
tion may result in delayed corn emergence and stunting
|
||
under certain environmental conditions including cool
|
||
temperatures, excessive rainfall/irrigation, and/or per-
|
||
sistent wet soil conditions occurring after application .
|
||
• Ensure the corn seed row is closed . Soil conditions that
|
||
cause poor seed furrow closure and coverage may result
|
||
in delayed corn emergence or stunting .
|
||
• Application of this product with other postemergence or
|
||
residual herbicides may increase the potential for crop
|
||
injury after corn has emerged .
|
||
• Early postemergence applications of Surtain may result
|
||
in crop response symptoms consisting of foliar spotting
|
||
on emerged leaves . Use of an adjuvant can increase the
|
||
level of foliar spotting on emerged leaves . Refer to
|
||
Additives section for more details on adjuvants .
|
||
• Tank mixing of Surtain with Glufosinate formulations for
|
||
early postemergence applications is NOT advised as
|
||
corn injury could result .
|
||
• Early postemergence applications of Surtain should be
|
||
made with water as the carrier . Sprayable fluid fertilizer
|
||
as an herbicide carrier for early postemergence applica -
|
||
tions in corn can typically cause corn injury up to and
|
||
including tissue burn (necrosis) . Sprayable fluid fertilizer
|
||
as a carrier is NOT advised for use with Surtain after
|
||
crop emergence unless typical fertilizer burn symptoms
|
||
are acceptable .
|
||
• Make applications of Surtain promptly after preparing
|
||
the spray mixture . Avoid use of spray solutions of
|
||
Surtain which have been allowed to stand or have been
|
||
stored in application equipment or the mix tank for an
|
||
extended period of time as corn injury could result .
|
||
Fallow and Postharvest Croplands
|
||
Surtain may be used for residual control of weeds at any
|
||
time of the year during the fallow period following crop har-
|
||
vest and before the following crop is planted .
|
||
Application Rate and Timing
|
||
Surtain may be applied in a single application or in
|
||
sequential applications .
|
||
For residual weed control, apply Surtain at 9 .2 to
|
||
17 .0 fl ozs/A .
|
||
Specific rotational crop intervals must be observed
|
||
between an application of Surtain and planting of the
|
||
following crop (see Crop Rotation Intervals section for
|
||
crop rotation restrictions) .
|
||
|
||
15
|
||
Crop-specific Restrictions
|
||
• DO NOT apply more than 17 .0 fl ozs/A of SurtainTM
|
||
herbicide (0 .083 lb ai/A of saflufenacil, 0 .133 lb ai/A
|
||
pyroxasulfone) in a single application .
|
||
• DO NOT apply more than 27 .0 fl ozs/A of Surtain
|
||
(0 .132 lb ai/A of saflufenacil, 0 .211 lb ai/A pyroxasulfone)
|
||
as a maximum cumulative amount from sequential appli -
|
||
cations in fallow and post harvest croplands per year .
|
||
• Maximum number of applications per year: 3
|
||
• Separate sequential applications by at least 30 days .
