Ground and Surface Water Protection
Point-source Contamination
To prevent point-source contamination, DO NOT mix or
load this pesticide product within 50 feet of wells (including
abandoned wells and drainage wells), sink holes, perennial
or intermittent streams and rivers, and natural or impound-
ed lakes and reservoirs. DO NOT apply pesticide product
within 50 feet of wells. This setback does not apply to
properly capped or plugged abandoned wells and does
not apply to impervious pad or properly diked
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

Mode of Action
Dyvel™ WG herbicide is a benzoic auxin agonist herbicide
belonging to mode of action Group 4 (WSSA) and
Group O (HRAC). Dyvel WG is readily absorbed by roots
and foliage, translocates throughout the plant, and accu-
mulates in areas of active growth, Dyvel WG interferes
with the plant growth resulting in control of susceptible
broadleaf weeds.
Resistance Management
While weed resistance to auxin agonist herbicides is rela-
tively infrequent, populations of resistant biotypes are
known to exist. Resistance management practices include:
1. Follow labeled application rate and weed growth stage
recommendations.
2. Avoid repeat application of herbicides with the same
mode of action.
3. Use tank mixes and sequential applications with other
effective herbicides possessing different modes of
action.
4. Rotate crops so crop competition, tillage, or herbicides
with alternative modes of action can be used to control
weed escapes.
Wheat Tolerance
Wheat is tolerant to Dyvel WG when applied according to
label directions under normal environmental conditions.
Crop injury may occur under stressful growing conditions
(e.g. seedling disease, extreme hot or cold weather, exces-
sive moisture, high soil pH, high soil salt concentration, or
drought). Dyvel WG application during periods of rapid
wheat growth may result in crop leaning; this condition is
temporary and will not reduce crop yield.
Application Instructions
Dyvel WG can be applied to actively growing weeds as
aerial, broadcast, or spot spray applications using water or
sprayable fertilizer as a carrier.
Application Rates
Application rates are 4.2 ozs/A for fallow application and
2.1 to 4.2 ozs/A for wheat postemergence application.
Refer to the Crop-specific Information section for crop-
specific application timing and other details.
Application Methods and Equipment
Dyvel WG may be applied by air or ground. Thorough
spray coverage is important for broadleaf 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 accurate and uniform distribu-
tion of spray droplets over the treated area, and to avoid,
spray drift to nontarget areas. Adjust equipment to main-
tain continuous agitation during spraying with good
mechanical or bypass agitation. Avoid overlaps that will
increase rates above the maximum use rates specified in
this label.
To avoid uneven spray coverage, DO NOT apply
Dyvel WG during periods of gusty wind or when wind is in
excess of 15 mph.
DO NOT cultivate within 7 days after applying Dyvel WG.
Aerial Application Requirements
Water Volume
Use 2 to 10 gallons of water per acre. Use the higher spray
volume when treating dense or tall vegetation.
The following spray drift management requirements must
be followed by aerial applicators to reduce the potential for
spray drift:
4. The distance of the outermost nozzles on the boom
. must not exceed 3/4 the length of the fixed wingspan or
90% of rotor blade diameter.
2-. Nozzles must always point backward parallel with the
^•airstream and never be pointed downward more than
""45 degrees.
3. Without compromising aircraft safety; release spray at a
..height of 10 feet or less above the crop canopy or tallest
-plants.
Aerial Application Equipment
Select nozzles designed to produce a minimal amount of
fee spray particles. Aerially apply at the lowest.safe height
to reduce exposing spray to evaporation and wind. The
applicator must follow the most restrictive use cautions to
avoid drift hazards, including those found in this labeling,
as well as state and local regulations and ordinances.
DO NOT use aerial equipment if spray particles can be
carried by wind into areas where sensitive plants are grow-
ing or when temperature inversions exist.
Ground Application Requirements
Water Volume
Use 3 to 50 gallons of spray solution per broadcast acre
for optimal performance. Use the higher spray volume
when treating dense or tall vegetation.
Ground Application Equipment
Select nozzles designed to produce a minimal amount of
fine spray particles. Spray with nozzles as close to the
weeds as practical for thorough weed coverage.
Cleaning Spray Equipment
Following application, clean application equipment
thoroughly using a strong detergent or commercial sprayer
cleaner according to the manufacturer's directions, fol-
lowed by triple rinsing with clean water.

cSpray Drift Management
It is the responsibility of the applicator to avoid spray drift
onto nontarget areas. The interaction of many equipment-
related and weather-related factors determines the
potential for spray drift. The applicator and the grower are
responsible for considering all these factors when making
decisions.
Applicators must follow the most restrictive use precau-
tions to avoid drift hazards, including those found in this
labeling as well as applicable state and local regulations
and ordinances.
Sensitive Crop Precautions
Avoid off-target movement. Use extreme care when apply-
ing Dyvel™ WG herbicide to prevent injury to desirable
plants. . . . ....
Dyvel WG may cause injury to desirable broadleaf plants
including beans, cotton, fruit trees, grapes, ornamentals,
peas, potatoes, soybeans, sunflowers, tobacco, and toma-
toes. These plants are most sensitive to Dyvel WG during
periods of rapid growth or flowering.
The applicator must be familiar with and take into account
the information covered in the following spray drift reduc-
tion advisory information.
Information on Droplet Size
The most effective way to reduce drift potential is to apply
the largest droplets that provide sufficient coverage and
control. Use coarse sprays (volume median diameter of
400 microns or more) to avoid potential herbicide drift.
Select nozzles designed to produce a minimal amount of
fine spray particles (less than 200 microns). Applying larger
droplets reduces drift potential but will not prevent drift if
applications are made improperly or under unfavorable
environmental conditions (see Wind; Temperature and
Humidity; and Temperature Inversions).
Controlling droplet size:
• Volume - Use high flow rate nozzles to apply the highest
practical spray volume. Nozzles with higher rated flows
produce larger droplets.
• Pressure - DO NOT exceed the nozzle manufacturer's
recommended pressures. For many nozzle types, lower
pressure produces larger droplets. When higher flow
rates are needed, use higher flow rate nozzles instead of
increasing pressure.
• Number of Nozzles - Use the minimum number of noz-
zles that provide uniform coverage.
• Nozzle Orientation - Orienting nozzles so that the spray
is released parallel to the airstream produces larger
droplets than other orientations and is recommended
practice. For aerial application, significant deflection from
the horizontal airstream will increase fine droplets and
increase drift potential.
• Nozzle Type - Use a nozzle type that is designed for the
intended application. With most nozzle types, narrower
spray angles produce larger droplets. Consider using
low-drift nozzles. DO NOT use nozzles producing a mist
droplet spray. For aerial application, straight-stream or
solid-stream nozzles oriented straight back produce the
largest droplets and the lowest drift.
Additives
Agriculturally approved drift-reducing additives may be
used to reduce fine droplets.
Swath Adjustment
When applications are made with a crosswind, the swath
will be displaced downwind. Therefore, on the upwind and
downwind edges of the field, the applicator must compen-
sate for this displacement by adjusting the path of the
application equipment (e.g. aircraft, ground) upwind. Swath
adjustment distance should increase with increasing drift
potential (higher wind, smaller droplets, etc.).
Wind
Drift potential is lowest between wind speeds of 3 to
10 mph. However, many factors, including droplet size and
equipment type, determine drift potential at any given
speed. If applying at wind speeds less than 3 mph, the
applicator must determine if conditions of temperature
inversion exist or stable atmospheric conditions exist at or
below nozzle height. DO NOT make applications into areas
of temperature inversions or stable atmospheric conditions.
NOTE: Local terrain can influence wind patterns. Every
applicator should be familiar with local wind patterns and
how they affect spray drift.
Temperature and Humidity
When making applications in low relative humidity, set up :
equipment to produce larger droplets to compensate for
evaporation. Droplet evaporation is most severe when con-
ditions are both hot and dry.
Temperature Inversions
Applications should not occur during temperature inver-
sions because drift potential is high. Temperature
inversions restrict vertical air mixing, which causes small
suspended droplets to remain in a concentrated cloud that
can move in unpredictable directions because of the light,
variable winds common during inversions. Temperature
inversions are characterized by increasing temperatures
with altitude and are common on nights with limited cloud
cover and light-to-no wind. They begin to form as the sun
sets and often continue into the morning. Their presence
can be indicated by ground fog; however, if fog is not pres-
ent, inversions can also be identified by the movement of
smoke from a ground source or an aircraft smoke genera-
tor. 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.
Sensitive Areas
This pesticide should only be applied when the potential for
drift to adjacent sensitive areas (e.g. residential areas, bod-
ies of water, known habitat for threatened or endangered
species, or nontarget plants) is minimal (e.g. when wind is
blowing away from sensitive areas).
Wind Erosion
Avoid treating powdery, dry, or light sandy soils when con-
ditions are favorable for wind erosion. Under these
conditions, the soil surface should first be settled by rainfall
or irrigation.
Additives
To improve postemergence weed control, agriculturally
approved surfactants or crop oil concentrate and sprayable
fertilizers (urea ammonium nitrate [DAN] or ammonium sul-
fate [AMS]) may be added, particularly in dry growing
conditions; refer to Table 2.
Nonionic Surfactant (NIS)
The standard label recommendation for normal growing
conditions is 1 quart of an 80% active NIS per 100 gallons
of water.
Crop Oil Concentrate (COC)
A crop oil concentrate must contain either a petroleum-oil
or vegetable-oil base and must meet all of the following
criteria:
• Nonphytotoxic
• Contain only EPA-exempt ingredients
• Provide good mixing quality in the jar test
• Successful in local experience
The exact composition of suitable products will vary;
however, vegetable-oil and petroleumrbil concentrates -
should contain emulsifiers to provide good mixing quality.
Highly refined vegetable oils have proven more satisfactory
than unrefined vegetable oils. For additional information,
see Compatibility Test for Mix Components.
Nitrogen Source
• UAN - Use 2 to 4 quarts of UAN (28%, 30%, or
32% nitrogen solution) per acre.
• AMS - AMS at 2.5 pounds per acre may be substituted
for UAN. Use high-quality AMS (spray grade) to avoid
plugging of nozzles. Avoid use of AMS in spray volume
less than 10 gallons per acre because of potential precip-
itation problems.
DO NOT use galvanized, brass, or aluminum application
equipment (e.g. nozzles, tanks, pipes) that will contact
spray solutions containing UAN or AMS.

Tank Mixing Information
Dyvel™ WG herbicide may be tank mixed with one or
more registered herbicide products according to the spe-
cific tank mixing instructions in this label and respective
product labels. Read and follow the applicable restrictions
and limitations and Directions For Use on all product
labels involved in tank mixing. Always follow the most
restrictive label use directions. Refer to the Crop-specific
Information section for tank mixing details. DO NOT tank
mix with Axial® herbicide or Discover* herbicide
products.
Mixing Dyvel WG with postemergence grass (graminicide)
herbicides may reduce the effectiveness of those products.
Physical incompatibility, reduced weed control, or crop
injury, may result from mixing Dyvel WG with other pesti-
cides (fungicides, herbicides, insecticides, or miticides),
additives, or fertilizers. Local agricultural authorities may be
a source of information when using other than
BASF-recommended tank mixes.
Dyvel WG may be used in tank mixtures with most foliar-
applied insecticides. However, DO NOT apply Dyvel WG
in tank mixtures with Lorsban® insecticide.
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 fol-
lowing mixing order instructions; use 2 teaspoons per
pound or 1 teaspoon per pint of labeled use rate per
acre.
3. Cap the jar and invert 10 cycles between component
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 should 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
compatible, repeat the compatibility test with the addi-
tion of a suitable compatibility agent. If the solution is
then compatible, 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 agitation throughout mixing.
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. Water-conditioning additives (including dry and liquid
fertilizers such as AMS or UAN)
5. Water-dispersible products (such as Dyvel™ WG
herbicide, dry flowables, wettable powders, suspension
concentrates or suspo-emulsions)
6. Water-soluble products and additives
7. Emulsifiable concentrates (including crop oil concen-
trate or methylated seed oil adjuvants)
8. Remaining quantity of water
Maintain agitation throughout application until spraying is
completed. 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. Continue agitation
while spraying.
Use Restrictions
• Maximum seasonal use rate - 4.2 ozs/A for fallow or
wheat postemergence application.
• DO NOT make more than one (1) application per crop
season.
• DO NOT apply to winter wheat in the fall.
• DO NOT apply to wheat underseeded to forage.
• Restricted-entry interval (REI) - 24 hours
• DO NOT graze livestock or harvest forage for hay from
treated areas for a minimum of 30 days following
application.
• Preharvest interval (PHI) - DO NOT harvest grain for
60 days following application.
• DO NOT apply through any type of irrigation equipment.
• DO NOT treat irrigation ditches or water used for crop
irrigation or domestic purposes.
Crop Rotation and Emergency
Replanting Intervals
Wheat may be planted anytime after a fallow application or
crop failure.
Cereals (barley, oats, triticale), corn, cotton, sorghum, and
soybean may be planted 30 days after application.
All other crops may be planted 120 days after application.
Crop-specific Information
Postharvest, Fallow, Crop Stubble, and
Set-aside
Dyvel WG can be applied either postharvest in the fall,
spring, or summer; during the fallow period; or to crop
stubble/set-aside acres. Apply Dyvel WG as a broadcast
or spot treatment to emerged and actively growing weeds
after crop harvest (postharvest) and before a killing frost, or
in the fallow cropland or crop stubble the following spring
or summer. See Crop Rotation and Emergency
Replanting Intervals section for the required interval
between application and planting.
Application Rate and Timing
Apply 4.2 ozs of Dyvel WG per acre. For best perform-
ance, apply Dyvel WG when annual weeds are less than
3 inches and perennial weeds are in early regrowth stage
(less than 4 inches) in late summer or fall following a mow-
ing or tillage treatment. An adjuvant system (refer to
Additives section for details) is required for optimum
broadleaf activity. Avoid disturbing treated areas following
application. Treatment may not kill weeds that develop
from seed or underground plant parts such as rhizomes or
bulblets after application. Use a sequential herbicide appli-
cation or other cultural practice to control later emerging
weeds.
Tank Mixtures
Broad-spectrum control of grass weeds and/or additional
broadleaf weeds will usually require a tank mix with another
herbicide. Dyvel WG may be tank mixed or applied
sequentially with one or more of, but not limited to, the fol-
lowing herbicide products:
• Clarity" herbicide
• Paramount0 herbicide
• 2,4-D
• glyphosate (e.g. Roundup* herbicide)
Apply Dyvel WG to wheat postemergence only. DO NOT
apply to winter wheat in the fall. For best performance,
apply Dyvel WG when annual weeds are small (less than
3 inches) and actively growing. An adjuvant system (refer to
Additives section for details) is required for optimum
broadleaf activity. Application of Dyvel WG to wheat during
Jj
IJ
10
(periods of rapid growth may result in crop leaning. This / C
condition is temporary and will not reduce crop yield. -^
Application to wheat may be made by aerial application
using 2 gallon of water or more per acre. Where dense
foliage is present, use more than 2 gallons of water per
acre.
Postemergence Application
Apply Dyvel™ WG herbicide at 2.1 to 4.2 ozs/A between
the 2-leaf stage and emergence of the fourth tiller.
DO NOT use crop oil concentrate for postemergence
in-crop application.
Tank Mixtures
Broad-spectrum control of broadleaf and grass weeds will
usually require a tank mix with another herbicide.
Dyvel WG may be tank mixed or applied sequentially with
one or more of, but not limited to, the following herbicide
products:
• Beyond® herbicide (for Clear-field® wheat only)
• Clearmax® herbicide (for Clear-field wheat only)
• 2,4-D amine
• MCPA
• Sulfonylurea-based herbicide (e.g. Ally® herbicide,
Express® herbicide, Harmony® Extra herbicide,
Peak* herbicide)
DO NOT tank mix or use in the same season with Axial®
herbicide or Discover® herbicide products.
