Wash the outside of gloves before removing. As soon
as possible, wash thoroughly and change into clean
 clothing.
Environmental Hazards
DO NOT apply directly to water, to areas where surface
water is present, or to 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 treated areas.
Groundwater Advisory
This chemical has properties and characteristics associat-
ed with chemicals detected in groundwater. This chemical
may leach into groundwater if used in areas where soils
are permeable, particularly where the water table is
shallow.
FIRST AID
If on skin

Surface Water Advisory
DO NOT apply directly to water, to areas where surface
water is present, or to intertidal areas below the mean high
water mark. Drift and runoff may be hazardous to aquatic
organisms in water adjacent to treated areas. DO NOT
 contaminate water when disposing of equipment washwa-
ter or rinsate. This product may impact surface water
quality due to runoff or rainwater. This is especially true for
poorly draining soils and soils with shallow groundwater.
This product is classiﬁed as having a high potential for
reaching surface water via runoff for several months or
more after application. A level, well-maintained vegetative
buffer strip between areas to which this product is applied
and surface water features including ponds, streams, and
springs will reduce potential loading of pyroxasulfone and
its 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 within 48 hours.
Point-source Contamination. To prevent point-source
contamination, DO NOT mix or load this or any other pes-
ticide within 50 feet of wells (including abandoned wells
and drainage wells, sinkholes, perennial or intermittent
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 as
described below. Mixing, loading, rinsing, or washing oper-
ations 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% of that of the
largest pesticide container or application equipment used
on the pad and have sufﬁcient capacity to contain all prod-
uct 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 mixing/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, or improper disposal of
excess pesticide, spray mixes, or rinsates. Check valves or
anti-siphoning devices must be used on all mixing
 equipment.

Product Information
Zidua® herbicide is a selective rate-dependent residual
 preemergence herbicide for controlling annual grass
weeds, sedges, and annual broadleaf weeds (including
 biotypes resistant to ACCase inhibitors, ALS inhibitors, and
glyphosate) that infest celery, chickpea, corn, cotton, dry
bulb onions, fallow, leek, mint, peanut, perennial cool-
season grasses grown for seed production, potato,
safﬂower, soybean, and sunﬂower listed in Table 1 and
wheat listed in Table 2. Refer to Crop-speciﬁc
 Information section for use directions speciﬁc to each
labeled crop.
Periods of dry weather following application of Zidua may
reduce herbicidal effectiveness. Zidua must be activated
by at least 1/2 inch of rainfall or irrigation before weed ger-
mination and emergence. When Zidua is not activated
and weeds emerge, a labeled postemergence herbicide or
shallow cultivation may be needed to control weed
escapes. Zidua does not control emerged weeds.
Herbicidal activity of Zidua may be reduced if trash on the
soil surface from the previous crop covers more than 25%
of the application area. Manage trash levels if needed with
combine straw shredder/spreaders, earlier burndown of
emerged weeds, or light tillage.

1 Weeds including annual bluegrass and Italian ryegrass have the ability to adapt to several different herbicide sites of action. Even though Zidua will
control these species, some weed escapes are possible. Multiple herbicides with multiple different effective sites of action MUST be used in tank mix-
tures or sequentially to limit these weed escapes to prevent or delay the onset of herbicide-resistant weed biotypes.
2 For control of these weeds, a tank mix partner or a sequentially applied herbicide partner is needed.
[Note to PM: Page 6 of 27]

7
Mode of Action
Zidua® herbicide acts to inhibit very long-chain fatty acid
synthesis as a Group 15 (WSSA)/Group K3 (HRAC) her-
bicide. It is a root-and-shoot growth inhibitor that controls
susceptible germinating seedlings before or soon after
they emerge from the soil.
Herbicide Resistance Management
Zidua is a Group 15/Group K3 herbicide. Any weed pop-
ulation may contain or develop plants naturally resistant to
Zidua and other Group 15 herbicides. Weed species with
resistance to Group 15 may eventually dominate the weed
population if Group 15 herbicides are used repeatedly in
the same ﬁeld or in successive years as the primary meth-
od of control for targeted species. This may result in partial
or total loss of control of those species by Zidua or other
Group 15 herbicides.
To delay herbicide resistance consider:
• Avoiding the consecutive use of Zidua or other target-
site-of-action Group 15 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
( 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; 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.
Crop Response
No crop injury is expected when Zidua is applied accord-
ing to label directions and under normal environmental
conditions. Application to crops under stress because of
inadequate or excess of moisture for normal crop develop-
ment, cool and hot temperatures, sodic soils, poorly
drained soils, hail damage, ﬂooding, pesticide injury,
mechanical injury, or widely ﬂuctuating temperatures may
result in crop injury.
Application Instructions
Application rates of Zidua may vary depending on soil tex-
ture. Refer to Table 3 for soil texture groups used in this
label unless a speciﬁc soil texture is mentioned. When use
rates are in ranges, apply the low rate for soils with coarse
texture or low organic matter; apply the high rates for ﬁne
soil textures, high organic matter, heavy soil surface plant
residue, or heavy weed pressure.

Application Timing
Zidua may be applied preplant surface, preplant
 incorporated, preemergence, early postemergence,
 postemergence-directed (layby), or in the fall. Refer to the
Crop-speciﬁc Information section for speciﬁc applica-
tion instructions (timings, rates, restrictions and
precautions) by crop.
Preplant Surface Application. Apply Zidua alone or in
tank mix within 45 days of planting. If weeds are present at
the time of application, use additional weed control meth-
ods, for example a tank mix with an appropriate
 postemergence herbicide(s), to control emerged weeds.
Preplant Incorporated (PPI) Application. Incorporate
Zidua 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 Zidua 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 Zidua in a tank mix with an appropriate
postemergence herbicide, for example a glyphosate-
containing product.
Early Postemergence Application. Zidua must be
applied and activated before weed seedling emergence or
in a tank mixture that controls emerged weeds. Zidua 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.
Postemergence-directed (Layby) Application. Zidua
must be applied as a directed spray between crop rows
and activated before weed seedling emergence or in a
tank mix that controls emerged weeds. Zidua will not con-
trol 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.
Fall/Winter Application for controlling weeds germi-
nating in the fall, or winter weeds. Zidua may be
broadcast surface applied in the fall or winter after crop
harvest. DO NOT apply to frozen or snow-covered soil.
Tillage operations may be conducted before or after apply-
ing Zidua. If tillage is used following an application, tillage
must be shallow (no more than 2-inches deep) to uniformly
incorporate the herbicide into the upper soil surface.
Application Methods and Equipment
Zidua may be applied by aerial or ground application or by
chemigation application via sprinkler or drip irrigation.
Thorough spray coverage is required for optimum weed
control and can be improved with proper nozzle and spray
volume selection. Use and conﬁgure application equip-
ment to provide an adequate spray volume, an accurate
and uniform distribution of spray droplets over the treated
area. Adjust equipment to maintain continuous agitation
during spraying with good mechanical or bypass agitation.
Avoid overlaps that will increase rates above the use rates
speciﬁed in this label.
Zidua may be applied using water or sprayable ﬂuid
 nitrogen fertilizer solutions as the spray carrier. DO NOT
apply this product without dilution in a spray carrier. Addi-
tionally, Zidua may be impregnated on and applied with
dry bulk fertilizer.
Spray Mix Preparation Advisory
Always pre-dissolve Zidua before adding it into the spray
tank. When dissolving Zidua for a spray mix, use a
 minimum of 4 gallons water per container of Zidua
(80 ounces) in an external container (e.g. 5-gallon bucket)
or in the sprayer induction system with constant agitation.
DO NOT pour Zidua straight into the sprayer inductor
system without minimum water and agitation.
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 5 or more gallons of
water per treated acre or 15 or more gallons of sprayable
ﬂuid nitrogen fertilizer per treated acre for weed control
 application.

Mandatory Spray Drift Management
Aerial Applications
• DO NOT release spray at a height greater than 10 ft
above the vegetative canopy, unless a greater applica-
tion height is necessary for pilot safety.
• For all applications, applicators are required to use a
medium to ultra coarse spray droplet size
(ASABE S572.1).
• The boom length must not exceed 65% of the wing-
span for airplanes or 75% of the rotor blade 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 when wind speeds exceed 10 miles
per hour 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 feet above the
ground or crop canopy.
• For all applications, applicators are required to use a
medium to ultra coarse spray droplet size
(ASABE S572.1).
• DO NOT apply when wind speeds exceed 10 miles
per hour at the application site.
• DO NOT apply during temperature inversions.
Spray Drift Advisories
The applicator is responsible for avoiding off-site spray
drift. Be aware of nearby non-target 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
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
should 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 should 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. Avoid applica-
tions during temperature inversions.
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.
Chemigation Application via Sprinkler and
Drip Irrigation Systems
Zidua® herbicide may be applied as a chemigation treat-
ment through sprinkler irrigation systems. Apply this
product ONLY through a sprinkler irrigation system of the
following type: center pivot, end tow, hand move, lateral
move, side (wheel) roll, or solid set. DO NOT apply this
product through any other type of sprinkler irrigation
system.
Zidua may also be applied as a chemigation treatment
through drip irrigation systems. All chemigation precau-
tions mentioned in this label for sprinkler irrigation systems
also apply for drip irrigation systems.
[Note to PM: Page 9 of 27]

10
Application may be made alone or in tank mixtures with
other herbicides on this label registered for use in speciﬁed
sprinkler or drip irrigation systems. Application must be
made within speciﬁc crop stage timings and product use
rates given in the container label Directions For Use .
Uniform distribution of Zidua
® herbicide-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 residue in the crop. If you have
questions about calibration, contact State Extension
 Service specialists, equipment manufacturers, or other
experts.
Proper calibration is the responsibility of the applicator. The
system must be properly calibrated (with water only) to
ensure the amount of Zidua applied corresponds to the
speciﬁed rate. Apply Zidua in volume minimums of 0.33 to
0.67 inch of water using the lower volume for coarse-
texture soils and the higher volume for ﬁne-texture soils.
Application made in high volumes of water (more than
1 inch) may result in reduced weed control.
Meter herbicide dilution into irrigation water through the
entire time of water application for center pivot and lateral
move sprinkler systems. For solid-set and hand-move
sprinkler irrigation systems and drip irrigation systems,
apply Zidua through the system at the beginning of the
set; then follow with additional water to reach volume mini-
mums as listed by soil type. To increase calibration
accuracy of injection metering equipment, dilute Zidua in a
minimum of 3 parts water to 1 part Zidua. Maintain agita-
tion in injection nurse tanks to keep a uniform herbicide
suspension during application.
Special Restrictions 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 if the need arises.
4. Tail water (runoff water) from chemigation that contains
Zidua needs be recirculated and/or contained in the
ﬁeld in a cistern or holding reservoir from the initial appli-
cation and/or used only on adjacent, approved crops for
which Zidua 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 either 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, for example a positive displacement injection
pump (e.g. diaphragm pump) effectively designed and
constructed of materials that are compatible with pesti-
cides 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, the water
from the public water system needs be discharged 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 reservoir 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
section.
Ground Application (Dry Bulk Fertilizer)
Zidua may be impregnated or coated onto dry bulk granu-
lar fertilizer carriers for residual soil surface (fall, preplant
surface, preplant incorporated) applications or for residual
weed control from postemergence over-the-top of cotton
applications. Impregnation or coating may be conducted
by in-plant bulk or on-board systems. Perform the mixing
operation in well-ventilated areas.
All individual state regulations relating to dry bulk granular
fertilizer blending, registration, labeling, and application are
the responsibility of the individual and/or company selling
the herbicide/fertilizer mixture.
Zidua may be impregnated on many commonly used dry
fertilizers. DO NOT impregnate on ammonium nitrate, fer-
tilizers containing ammonium nitrate, potassium nitrate,
sodium nitrate, or powdered limestone.
Fertilizer application rates of at least 200 lbs to 700 lbs per
acre of herbicide and fertilizer blend will provide adequate
[Note to PM: Page 10 of 27]

11
distribution or coverage of Zidua® herbicide across the
soil surface. Application of impregnated fertilizer must be
made uniformly to the soil to prevent possible crop injury
and offer satisfactory weed control. Impregnated fertilizer
spread at half rate and overlapped to obtain a full rate
offers a more uniform distribution. A shallow (less than
2 inches) incorporation is desirable for improved weed
control. Deeper incorporation dilutes the herbicide layer
near the soil surface and may result in unsatisfactory weed
 control.
To calculate the herbicide rate when using dry bulk fertiliz-
er applications:
[ozs of Zidua
 per acre X 2000]
= ozs of Zidua for
pounds fertilizer per acre 1 ton of fertilizer
To impregnate Zidua on bulk fertilizer, use a closed
 rotary-drum mixer or other commonly used dry bulk fertil-
izer blender equipped with suitable spray equipment. Mix
Zidua with sufﬁcient water to form a sprayable slurry mix-
ture. Spray nozzles must be directed to provide uniform
fertilizer coverage while avoiding spray contact with mixing
equipment. Nonuniform impregnation can cause crop inju-
ry or unsatisfactory performance. Spray herbicide mixture
onto fertilizer after blending has started. Addition of a suit-
able drying agent may be necessary if the fertilizer and
herbicide blend is too wet for uniform application due to
high humidity, high urea concentration, or low fertilizer use
rate. Slowly add the drying agent to the blend until a ﬂow-
able mixture is obtained. Drying agents are not intended
for use with on-board impregnation systems.
Under some conditions, fertilizer impregnated with Zidua
may clog air tubes or deﬂector plates on pneumatic appli-
cation systems. Mineral oil may be added to Zidua before
blending with fertilizer to reduce plugging. DO NOT use
drying agents when mineral oil is used. To avoid separation
of Zidua and mineral oil mixes in cold temperatures, keep
mixture heated or agitated before blending with fertilizer.
Mineral oil may be used with inplant blending stations or
with on-board injection systems.
Uniformly apply the treated fertilizer with accurately cali-
brated and proper equipment immediately after
impregnation to avoid lump formation and spreading
 difﬁculties.
Accurate calibration of fertilizer application equipment and
uniform fertilizer distribution is essential for satisfactory
weed control.
Cleaning Spray Equipment
Clean application equipment thoroughly by using a strong
detergent or commercial sprayer cleaner according to the
manufacturer’s directions. Triple rinse the equipment
before and after applying Zidua.
Additives
Zidua is formulated to provide optimal residual pre-
emergence weed control. However, several tank mixes
with Zidua may require an adjuvant to improve burndown
of emerged weeds. Therefore, an adjuvant may be used
with Zidua tank mixes that are applied fall, preplant,
 preemergence, or early postemergence. Follow the adju-
vant directions for the tank mix partner of Zidua.
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.
Zidua 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. Follow the adjuvant directions for the tank mix part-
ner of Zidua. Read and follow tank mix product labels for
application instructions, use restrictions and precautions,
and rotational cropping guidance.
Physical incompatibility, reduced weed control, or crop
injury may result from mixing Zidua with other pesticides,
additives, or fertilizers.
Compatibility Test for Tank Mix Products
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 mix-
ing order using 2 teaspoons for each pound or
1 teaspoon for each pint of label 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
 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.
[Note to PM: Page 11 of 27]

12
Mixing Order
Maintain agitation throughout mixing and application 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. Water-soluble additives (dry and liquid fertilizers
including ammonium sulfate or urea ammonium nitrate)
5. Water-dispersible products (including dry ﬂowables,
wettable powders, suspension concentrates, or suspo-
emulsions) - Add Zidua
® herbicide at this point in the
mixing process.
6. Water-soluble products
7. Emulsiﬁable concentrates (including methylated seed
oil adjuvants)
8. Remaining quantity of water
If the spray mixture is allowed to settle for any period of
time, thorough agitation is essential to resuspend the mix-
ture before spraying is resumed. Continue agitation while
spraying.
Use Restrictions
• Maximum use rate - Refer to Crop- speciﬁc
 Information section for maximum application use rates
of Zidua in each crop and use pattern.
• Refer to Crop-speciﬁc Information for additional crop
use restrictions.
• DO NOT contaminate irrigation ditches or water used for
domestic purposes.
• Irrigation - DO NOT use ﬂood irrigation to apply, acti-
vate, or incorporate Zidua.
• Zidua is not for sale, distribution, or use in Nassau
and Suffolk counties in New York State.
• Emergency replanting intervals - If a labeled crop
treated with Zidua is lost to crop failure (because of envi-
ronmental factors including drought, frost, hail, etc.), the
crop may be replanted immediately. However, DO NOT
repeat application of Zidua after crop failure. A sequen-
tial application can be made as long as the maximum
 cumulative rate for the crop and soil per year is not
exceeded.
Use Precautions
• Crop rotation intervals - Use Table 5 to determine the
proper interval between Zidua application and the plant-
ing of rotational crops. Determine the crop rotation
interval for tank mix products, and use the most restric-
tive interval of all products applied.

application followed by spring application, or sequential
applications in the spring), the maximum combined rate of
Zidua that may be applied in corn per year is 2.75 ozs/A
(0.146 lb ai/A of pyroxasulfone) on coarse soils or 5.0 ozs/A
(0.266 lb ai/A of pyroxasulfone) on all medium-to-ﬁne soils.
Crop-speciﬁc Restrictions
• On coarse soil - DO NOT apply more than 2.75 ozs/A
of Zidua (0.146 lb ai/A of pyroxasulfone) in a single appli-
cation or as a maximum cumulative amount from
sequential applications in corn per year.
• On medium soil:
- DO NOT apply more than 3.0 ozs/A of Zidua
(0.159 lb ai/A of pyroxasulfone) in a single application.
- DO NOT apply more than a maximum cumulative
amount of 5.0 ozs/A of Zidua (0.266 lb ai/A
 pyroxasulfone) from sequential applications in corn per
year.
• On ﬁne soil:
- DO NOT apply more than 4.0 ozs/A of Zidua
(0.213 lb ai/A of pyroxasulfone) in a single application.
- DO NOT apply more than a maximum cumulative
amount of 5.0 ozs/A of Zidua (0.266 lb ai/A
 pyroxasulfone) from sequential applications in corn per
year.
• Maximum number of applications per year: 2
• Separate sequential applications by at least 14 days.
[Note to PM: Page 14 of 27]

15
• DO NOT harvest sweet corn ears for human consump-
tion less than 37 days after application of Zidua®
herbicide.
Crop-speciﬁc Precautions
• Seeding depth - Corn seed must be planted a mini-
mum 1-inch deep.
Cotton
Zidua can be applied postemergence- directed (layby) to
cotton for residual preemergence control of listed weeds
(Table 1), or applied postemergence to cotton prior to
weed emergence when impregnated onto dry bulk fertilizer
and spread for residual preemergence weed control. Use
Zidua as part of a weed control program in cotton either
in combination or sequen tially with other herbicides for a
broader spectrum of weed control and/or control of
emerged weeds. Before applying to cotton, verify with your
local seed company (supplier) the selectivity of Zidua on
your variety to avoid potential injury.
No crop injury is expected when Zidua is applied
 postemergence-directed (layby) or when applied poste-
mergence impregnated onto dry bulk fertilizer. However,
some visual cotton response is possible when Zidua is

coarse soils and 5.0 ozs/A (0.266 lb ai/A of pyroxasulfone)
on medium-to-ﬁne soils.
Crop-speciﬁc Restrictions
• On coarse soil - DO NOT apply more than 1.5 ozs/A of
Zidua (0.08 lb ai/A of pyroxasulfone) in a single applica-
tion or as a maximum cumulative amount from
sequential applications in sunﬂower per year.
• On all soils other than coarse:
- DO NOT apply more than 4.0 ozs/A of Zidua
(0.213 lb ai/A of pyroxasulfone) in a single application.
- DO NOT apply more than a maximum cumulative
amount of 5.0 ozs/A of Zidua (0.266 lb ai/A
 pyroxasulfone) from sequential applications in
 sunﬂower per year.
• Maximum number of applications per year: 3
• Separate sequential applications by at least 14 days.
• DO NOT apply Zidua preplant incorporated to
sunﬂower.
• DO NOT apply Zidua to sunﬂower at cracking or
cotyledon stage.
• DO NOT apply a tank mix of Zidua and Beyond
®
 herbicide on Clearﬁeld ® sunﬂower hybrids/varieties.
• There is no required (preharvest) interval between a pre-
plant and preemergence application of Zidua and
sunﬂower harvest.
[Note to PM: Page 21 of 27]

22
• DO NOT apply Zidua® herbicide postemergence less
than 60 days before harvest of sunﬂower seed.
Crop-speciﬁc Precautions
• Sunﬂower seed quality - Plant high quality seed.
• Seedbed preparation - The seedbed MUST be pre-
pared to ensure good seed row closure and soil
coverage of the seed.
• The use of Zidua may result in temporary growth sup-
pression or leaf burn in sunﬂower under stressful
conditions including inadequate or excessive soil mois-
ture or rainfall, cool and hot temperatures, compacted or
crusted soils, improper planting depth, injury from other
pesticides, disease or other pest damage, mechanical
injury, nutrient imbalances, or other conditions known to
cause plant stress.
• If Zidua is tank mixed with another herbicide other than
glyphosate or a graminicide, use a lower rate within the
Zidua rate range for the application timing and soil tex-
ture (as speciﬁed in Table 17).
Wheat
Zidua may be applied preplant surface, preemergence,
delayed preemergence, or early postemergence in
fall-seeded or spring-seeded wheat for residual pre-
emergence control or suppression of listed weeds
(Table 2) and suppression of other listed weeds (Table 1).
Use Zidua as part of a weed control program in wheat
either in combination or sequentially with other herbicides
for a broader spectrum of weed control and/or control of
emerged weeds.
Crop Response
Zidua applied preplant surface or preemergence can
cause wheat injury. Under stressful conditions (including
inadequate or excessive moisture, cool or hot tempera-
tures, compacted soils, injury from other pesticides,
disease or other pest damage, mechanical injury, nutrient
imbalances, or other conditions known to cause plant
stress), Zidua injury will be in intensiﬁed.
No crop injury is expected when Zidua is applied delayed
 preemergence or early postemergence. However, some
visual wheat response is possible when Zidua is applied
to wheat under stressful conditions including inadequate
or excessive moisture, cool or hot temperatures, compact-
ed soils, injury from other pesticides, disease or other pest
damage, mechanical injury, nutrient imbalances, or other
conditions known to cause plant stress.
Wheat response is most often visible as stunting and/or
discoloration of leaf tissue (e.g. chlorosis), but in its most
severe form can result in stand loss and yield reduction.
The greatest potential for wheat response occurs when
Zidua concentrates in the crop row. Unacceptable wheat
response may be caused by uneven application, soil clods
or disturbances, an open/cracked seed furrow that allows
herbicide to directly contact the seed, or a deep seed
furrow that allows herbicide concentration after a
rain/irrigation event during wheat germination.
Certain wheat varieties can be more sensitive to Zidua.
Before applying to wheat, verify sensitivity with your local
seed company (supplier), university extension specialist
(e.g. wheat breeder, weed scientist, county agent, etc.), or
BASF representative.
Application Rate
Apply Zidua in wheat at the residual rates in Table 18.

Early
postemergence 1.0 to 2.5 1.0 to 2.5 1.0 to 2.5
1 Refer to Table 3 for deﬁnition of soil-texture groups.
Application Timing
Zidua may be applied in a single application or in sequen-
tial applications relative to the growth stage of wheat.
Preplant Surface Application
Apply Zidua at the use rates speciﬁed in Table 18 as a
broadcast spray to the soil surface no more than 14 days
before planting on all soil types. Soil disturbance after
application from planters/drills may result in herbicide
incorporation that can result in unacceptable crop injury, or
displacement of Zidua that can result in inconsistent weed
control. See State-speciﬁc Use Instructions for appli-
cations in Idaho, Montana, Oregon, and Washington.
Preemergence Surface Application
Apply Zidua at the use rates speciﬁed in Table 18 after
planting but before wheat spiking as a broadcast spray to
the soil surface with uniform seedbed that is ﬁrm and free
of clods. Ensure good seed row closure and soil coverage
to avoid contact with Zidua. As the interval from planting
to application increases, the potential for crop injury
decreases. See State-speciﬁc Use Instructions for
applications in Idaho, Montana, Oregon, and Washington.
Delayed Preemergence Surface Application
Apply Zidua at the use rates speciﬁed in Table 18 as a
broadcast spray to the soil surface following wheat plant-
ing when 80% of germinated wheat seeds have a shoot at
least 1/2-inch long until wheat spiking.
Early Postemergence Application
Apply Zidua at the use rates speciﬁed in Table 18 as a
broadcast spray to wheat at spiking up to the 4th-tiller
growth stage. Zidua will only suppress or control labeled
[Note to PM: Page 22 of 27]

23
weeds that germinate after the early postemergence appli-
cation and rainfall/irrigation activation. Apply Zidua®
 herbicide as early as possible after wheat emergence to
prevent weed emergence.
Sequential Application
Zidua may be applied as a sequential or split application
program where a preplant, preemergence, or delayed
 preemergence application is followed by an early
 postemergence application or where multiple early
 postemergence applications are made. DO NOT apply
more than a maximum cumulative amount of 2.5 ozs/A
(0.133 lb ai/A of pyroxasulfone) per year.
State-speciﬁc Use Instructions for Preplant and
Preemergence Applications in Idaho, Montana,
Oregon, and Washington. Apply Zidua preplant surface
or preemergence in fall-seeded winter wheat for residual
weed control. DO NOT apply on spring wheat. Apply
Zidua only to a uniform seedbed that is ﬁrm and free of
clods, cracks, excess trash (previous crop residue), and
weed growth. The seedbed MUST be prepared to ensure
good seed row closure and soil coverage of the seed.
Open furrows or poor furrow closure can result in crop
injury. Use high quality seed. Plant seed at least 1-inch
deep, but not greater than 1.5-inches deep to avoid crop
injury. Avoid planting seed into loose, powdery soil
because unacceptable crop injury may result if soil settles
and ﬁnal planting depth is less than 1-inch. Apply Zidua
preplant surface or preemergence at 1.0 to 2.0 ozs/A on
medium soils and at 1.25 to 2.0 ozs/A on ﬁne soils.
DO NOT apply on coarse soils. Avoid application to soils
with less than 2% organic matter and/or pH greater than
7.5 because unacceptable crop injury may occur. Follow all
other application instructions and restrictions and limita-
tions for preplant and preemergence applications of Zidua
in wheat.
Crop-speciﬁc Restrictions
• DO NOT apply more than 2.5 ozs/A of Zidua
(0.133 lb ai/A of pyroxasulfone) in a single application.
• DO NOT apply more than a maximum cumulative
amount of 2.5 ozs/A of Zidua (0.133 lb ai/A of
 pyroxasulfone) from sequential applications in wheat per
year.
• Maximum number of applications per year: 2
• Separate sequential applications by at least 14 days.
• DO NOT apply Zidua to durum wheat.
• DO NOT seed wheat deeper than 1.5 inches after a
 preplant application or before a preemergence or
delayed preemergence application.
• DO NOT apply Zidua to ﬂooded ﬁelds or saturated soils.
• DO NOT apply preemergence if 1/4 inch or more rain is
expected within 48 hours after application.
• DO NOT irrigate ﬁelds after a preemergence or delayed
preemergence application until wheat spiking.
• DO NOT apply preplant, preemergence, or delayed
 preemergence to broadcast-seeded wheat.
• DO NOT apply Zidua [Alternate Text - preplant surface],
preplant incorporated, [Alternate Text - preemergence] in
wheat.
• Wheat forage and hay can be fed or grazed 7 or more
days after application.
Crop-speciﬁc Precautions
• Apply Zidua only to a uniform seedbed that is ﬁrm and
free of clods, cracks, excess trash (previous crop resi-
due), and weed growth. The seedbed MUST be
prepared to ensure good seed row closure and soil cov-
erage of the seed. Open furrows or poor furrow closure
can result in crop injury. Use high quality seed. Plant
seed at least 3/4-inch deep to avoid crop injury.
• The use of Zidua in wheat may result in temporary or
sustained growth suppression and chlorosis if high
 rainfall or irrigation leads to extended periods of water-
saturated soil during early seedling development. To
reduce crop response, avoid applying Zidua if a long
period of rain is expected before wheat emergence.
