 Case Number: 00480574
Dear Wes Marchione
The amended label referred to above, submitted in connection with registration under the
Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), as amended, is acceptable.
However, EPA reviewed only the label changes highlighted, marked, or otherwise indicated on
the submitted label. Any other changes to the previously approved label that were not clearly
highlighted, marked, or otherwise indicated in your submission were not reviewed and may
form the basis of regulatory and/or enforcement action if later discovered by the Agency.
Further, submission of a label amendment application with unidentified changes may be
considered a knowing submission of false information to the Agency. This approval does not
affect any conditions that were previously imposed on this registration. You continue to be
subject to existing conditions on your registration and any deadlines connected with them.
The label submitted with the application has been stamped “Accepted Only Indicated Revisions
Reviewed” and is enclosed for your records.
This labeling supersedes all previously accepted labeling. You must submit one copy of the final
printed labeling before you release the product for shipment with the new labeling. In
accordance with 40 C.F.R. § 152.130(c), you may distribute or sell this product under the
previously approved labeling for 18 months from the date of this letter. After 18 months, you
may only distribute or sell this product if it bears this new revised labeling or subsequently

Case Number 00480574
approved labeling. “To distribute or sell” is defined under FIFRA section 2(gg) and its
implementing regulation at 40 C.F.R. § 152.3.
Should you wish to add/retain a reference to the company’s website on your label, then please
be aware that the website becomes labeling under FIFRA and is subject to review by the
Agency. If the website contains any false or misleading statement, design, or graphic, the
product may be misbranded and unlawful to sell or distribute under FIFRA Sections 2(q)(1)(A)
and 12(a)(1)(E). 40 C.F.R. § 156.10(a)(5) lists examples of statements EPA may consider false or
misleading. In addition, regardless of whether a website is referenced on the product label,
claims made as part of the product’s sale or distribution may not substantially differ from those
claims approved through the registration process under FIFRA Section 12(a)(1)(B). Therefore,
should the Agency find or if it is brought to our attention that a website contains false or
misleading statements or claims substantially differing from the EPA approved registration, the
product will be referred to the EPA’s Office of Enforcement and Compliance Assurance.
Your release for shipment of the product constitutes acceptance of these conditions. If these
conditions are not complied with, the registration will be subject to cancellation in accordance
with FIFRA section 6.
If you have any questions, please contact Francisco Llarena-Arias at 202-566-2816 or at llarena-

USERS SHOULD: Remove clothing/PPE immediately if pesticide gets inside. Then wash thoroughly
and change into clean clothing.
USERS SHOULD: Remove PPE immediately after handling this product. 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 washwaters or rinsate.
DO NOT apply where/when conditions could favor runoff.
Groundwater Advisory
Nicosulfuron is known to leach through soil into groundwater under certain conditions as a result of label
use. This chemical may leach into groundwater if used in areas where soils are permeable, particularly
where the water table is shallow.
Surface Water Advisory
This product may impact surface water quality due to runoff of rain water. This is especially true for poorly
draining soils and soils with shallow ground water. 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
vegetative buffer strip between areas to which this product is applied and surface water features such as
ponds, streams, and springs will reduce the potential loading of this product from runoff water and
sediment. Runoff of this product will be greatly reduced by avoiding applications when rainfall or irrigation
is expected to occur within 48 hours.
Windblown Soil Particles Advisory
This product has the potential to move off-site due to wind erosion. Soils that are subject to wind erosion
usually have a high silt and/or fine to very fine sand fractions and low organic matter content. other
factors which can affects the movement of windblown soil include the intensity and direction of prevailing
winds, vegetative cover, site slope, rainfall, and drainage patterns. Avoid applying this product if
prevailing local conditions may be expected to result in off-site movement.
Non-target organism Advisory
This product is toxic to plants and may adversely impact the forage and habitat of non-target organisms,
including pollinators, in areas adjacent to the treated area. Protect the forage and habitat of non-target
organisms by minimizing spray drift. For further guidance and instructions on how to minimize spray drift,
refer to the Spray Drift Management section of this label.

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 washwaters or rinsate.
DO NOT apply where/when conditions could favor runoff.
Groundwater Advisory
Nicosulfuron is known to leach through soil into groundwater under certain conditions as a result of label
use. This chemical may leach into groundwater if used in areas where soils are permeable, particularly
where the water table is shallow.
Surface Water Advisory
This product may impact surface water quality due to runoff of rain water. This is especially true for poorly
draining soils and soils with shallow ground water. 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
vegetative buffer strip between areas to which this product is applied and surface water features such as
ponds, streams, and springs will reduce the potential loading of this product from runoff water and
sediment. Runoff of this product will be greatly reduced by avoiding applications when rainfall or irrigation
is expected to occur within 48 hours.
Windblown Soil Particles Advisory
This product has the potential to move off-site due to wind erosion. Soils that are subject to wind erosion
usually have a high silt and/or fine to very fine sand fractions and low organic matter content. Other
factors which can affects the movement of windblown soil include the intensity and direction of prevailing
winds, vegetative cover, site slope, rainfall, and drainage patterns. Avoid applying this product if
prevailing local conditions may be expected to result in off-site movement.

PRODUCT INFORMATIONProduct Information
Zest WDG herbicide is a water-dispersible granule used at a rate of 0.33 - 1.33 ounces (0.015 - 0.062
lb ai) per acre for selective postemergence grass weed control in field corn grown for silage, seed or
grain, popcorn and sweet corn, and 0.67 - 1.33 ounces (0.031 - 0.062 lb ai) per acre in grain sorghum
containing the INZEN trait.


RESTRICTIONSRestrictions

V93 / Zest WDG / MSTR / Amend with edits / 09-27-2022 Page 12
 DO NOT make more than two applications of Zest WDG per year. The combined dosage of sequential
Zest WDG applications cannot exceed 1.33 ounces (0.062 lb ai) per acre in corn and 1.8 ounces (0.084
lb ai) per acre in grain sorghum containing the INZEN trait per year unless.
 DO NOT apply Zest WDG to corn or grain sorghum containing the INZEN trait that exhibits herbicide
injury from previous applications made to the current or preceding crop.
 DO NOT use liquid nitrogen fertilizer as the total carrier solution for postemergence applications.
 Injury or loss of desirable trees or vegetation may result from failure to observe the following:
o DO NOT apply Zest WDG or drain or flush application equipment on or near desirable
trees or other plants, or on areas where their roots may extend, or in locations where the
chemical may be washed or moved into contract with their roots.
o DO NOT use on lawns, walks, driveways or tennis courts. Prevent drift of spray to
desirable plants.
o DO NOT contaminate any body of water
 DO NOT apply this product through any type of irrigation system.
PRECAUTIONSPrecautions
 Zest WDG may interact with certain insecticides previously applied to the crop. Crop response varies
with field corn type, insecticide used, insecticide application methods, and soil type.
 Zest WDG may be applied to corn previously treated with insecticide including Fortress (AI:
chlorethoxyfos; Reg. No. 5481-493), Smartchoice (AI: bifenthrin + chlorethoxyfos; Reg. No. 5481-561,
5481-579), Aztec (AI: cyfluthrin + tebupirimphos; Reg. No. 5481-9028, 5481-9030), or Force (AI:
tefluthrin; Reg. No. 100-1075, 100-1253, 100-1610, 100-1625), or other non-organophosphate soil
insecticides regardless of soil type.
 It is possible that pollen-mediated gene flow from grain sorghum containing the INZEN trait to weedy
relatives, including johnsongrass or shattercane, may contribute to the development of resistance to
ALS herbicides in these biotypes.
 Temporary yellowing and reduction in height of grain sorghum hybrids containing the INZEN trait may
occur following a postemergence application of Zest WDG. Crop responses may be more pronounced
when conditions exist that result in slowed crop growth, including but not limited to cloudy, cool, or wet
conditions. Normal growth and appearance will resume when normal growing conditions return.
 Adherence to the Corteva Stewardship Program and Best Management Practices is necessary to
reduce the risk of the development of resistance to ALS herbicides in weedy relatives.
Crop injury may occur following an application of ACCENT® if there is a prolonged period of cold weather
and/or in conjunction with wet soils.[AJ1][WS2]
 Prevent drift or spray onto desirable plants.
 Thoroughly clean application equipment immediately after use (See Sprayer Cleanup section of this
label).
 For all application systems, use 50-mesh or larger strainer screens.

WEED RESISTANCE MANAGEMENTeed Resistance Management
Zest WDG, which contains the active ingredient nicosulfuron, is a Group 2 herbicide based on the mode
of action classification system of the Weed Science Society of America.

Proactively implementing diversified weed control strategies to minimize selection for weed populations
resistant to one or more herbicides is a best practice. A diversified weed management program may
include the use of multiple herbicides with different sites of action and overlapping weed spectrum with or
without tillage operations and/or other cultural practices.

Research has demonstrated that using the labeled rate and directions for use is important to delay the
selection for resistance.

The continued effectiveness of this product depends on the successful implementation of a weed
resistance management program.

To aid in the prevention of developing weeds resistant to this product, users should:

 Scout fields before application to ensure herbicides and rates will be appropriate for the weed species
and weed sizes present.
 Start with a clean field, using either a burndown herbicide application or tillage.
 Control weeds early when they are relatively small (less than 4 inches).
 Apply full rates of this product for the most difficult to control weed in the field at the specified time
(correct weed size) to minimize weed escapes.
 Scout fields after application to detect weed escapes or shifts in control of weed species.
 Control weed escapes before they reproduce by seed or proliferate vegetatively.
 Report any incidence of non-performance of this product against a particular weed to your company
representative, local retailer, or county extension agent.
 Contact your company representative, crop advisor, or extension agent to find out if suspected
resistant weeds to this MOA have been found in your region. If resistant biotypes of target weeds
have been reported, use the application rates of this product specified for your local conditions. Tank
mix products so that there are multiple effective sites of actions for each target weed.
 If resistance is suspected, treat weed escapes with an herbicide having a site of action other than
group 2 and/or use nonchemical methods to remove escapes, as practical, with the goal of preventing
further seed production.
 Suspected herbicide-resistant weeds may be identified by these indicators:
 Failure to control a weed species normally controlled by the herbicide at the dose applied,
especially if control is achieved on adjacent weeds;
 A spreading patch of non-controlled plants of a particular weed species; and
 Surviving plants mixed with controlled individuals of the same species.
Additionally, users should follow as many of the following herbicide resistance management practices as
is practical:
 Use a broad spectrum soil-applied herbicide with other sites of action as a foundation in a weed
control program.
 Utilize sequential applications of herbicides with alternative sites of action.
 Rotate the use of this product with non-group 2 herbicides.
 Avoid making more than two applications of this product and any other group 2 herbicides within a
single growing season unless mixed with an herbicide with a different site of action with an
overlapping spectrum for the difficult-to-control weeds.
 Incorporate non-chemical weed control practices, such as mechanical cultivation, crop rotation, cover
crops and weed- free crop seeds, as part of an integrated weed control program.
 Use good agronomic principles that enhance crop development and crop competitiveness.

V93 / Zest WDG / MSTR / Amend with edits / 09-27-2022 Page 14
 Thoroughly clean plant residues from equipment before leaving fields suspected to contain resistant
weeds.
 Manage weeds in and around fields, during and after harvest to reduce weed seed production.

Contact the local agricultural extension service, company representative, agricultural retailer or crop
consultant for further guidance on weed control practices as needed.
INTEGRATED PEST MANAGEMENTntegrated Pest Management
This product may be used as part of an Integrated Pest Management (IPM) program that can include
biological, cultural, and genetic practices aimed at preventing economic pest damage. IPM principles and
practices include field scouting or other detection methods, correct target pest identification, population
monitoring, and treating when target pest populations reach locally determined action thresholds. Consult
your state cooperative extension service, professional consultant or other qualified authorities to
determine appropriate action treatment threshold levels for treating specific pest / crop systems in your
area.
SPRAY DRIFT ADVISORIES
THE APPLICATOR IS RESPONSIBLE FOR A VOIDING OFF-SITE SPRAY DRIFT. B E AW ARE OF NEARBY NON- TARGET SITES AND ENVIRONMENTAL CONDITIONS.
IMPORTANCE OF DROPLET SIZE
MANDATORY SPRAY DRIFT MANAGEMENT
Aerial Applications:
 DO NOT release spray at a height greater than 10 feet above the vegetative canopy, unless a
greater application height is necessary for pilot safety.
 For applications prior to the emergence of crops and target weeds, applicators are required to
use a Coarse or coarser droplet size (ASABE S572.1).
 For all other applications, applicators are required to use a Medium or coarser droplet size
(ASABE S572.1).
 The boom length must not exceed 65% of the wingspan for airplanes or 75% of the
rotor blade diameter for helicopters.
 Applicators must use one-half 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 Boom Applications:
 Apply with the nozzle height recommended by the manufacturer, but no more than 3 feet
above the ground or crop canopy unless making a turf, pasture, or rangeland application, in
which case applicators may apply with a nozzle height no more than 4 feet above the ground.
 For applications prior to the emergence of crops and target weeds, applicators are required to
use a Coarse or coarser droplet size (ASABE S572.1).
 For all other applications, applicators are required to use a Medium or coarser 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.

V93 / Zest WDG / MSTR / Amend with edits / 09-27-2022 Page 15
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
 V olume - Increasing the spray volume so that larger droplets are produced will reduce spray
drift. use the highest practical spray volume for the application. If a greater spray volume is
needed, consider using a nozzle with a higher flow rate.
 Pressure - use the lowest spray pressure 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 INVERSIONS
Drift potential is high during a temperature inversion. Temperature 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 applications during temperature inversions.
WIND
Drift potential generally increases with wind speed. A VOID APPLICATIONS DURING GUSTY WIND CONDITIONS. Applicators need to be familiar with local wind patterns and terrain that could affect spray drift.
DRIFT CONTROL ADDITIVES
Using product compatible drift control additives can reduce drift potential. When a drift control additive is
used, read and carefully observe cautionary statements and all other information on the additives label.
If using an additive that increases viscosity, ensure that the nozzles and other application equipment will
function properly with a viscous spray solution.
Preferred drift control additives have been certified by the Chemical Producers and Distributors
Association (CPDA).

V93 / Zest WDG / MSTR / Amend with edits / 09-27-2022 Page 16
Mixing Directions
Select a spray volume that will ensure thorough coverage and a uniform spray pattern. If tank mixing with
other herbicides, always consult the label of the tank mix partner(s) for minimum spray volume
requirements and apply the tank mixture using a water volume advised for all products.
1. Fill the tank 1/4 to 1/3 full of water.
2. While agitating, add the required amount of Zest WDG.
3. Continue agitation until the Zest WDG is fully dispersed, at least 5 minutes.
4. Once the Zest WDG is fully dispersed, maintain agitation and continue filling tank with water.
Thoroughly mix Zest WDG with water before adding any other material.
5. If tank mixing Zest WDG with another herbicide, follow this mixing order: dry flowables and soluble
granules, followed by liquids, then oil dispersions (od) or emulsifiable concentrates (ec). Maintain
continuous agitation.
6. As the tank is filling, add the required spray adjuvants (crop oil concentrate, nonionic surfactant, or
ammonium nitrogen fertilizer).
7. If the mixture is not continuously agitated, settling will occur. If settling occurs, thoroughly re-agitate
before using.
Apply Zest WDG spray mixture within 24 hours of mixing to avoid product degradation.
If Zest WDG and a tank mix partner are to be applied in multiple loads, pre-slurry the Zest WDG in
clean water prior to adding to the tank. This will prevent the tank mix partner from interfering with the
dissolution of the Zest WDG.
TANK MIX COMPATIBILITY TESTING
Perform a jar test prior to tank mixing to ensure compatibility of Zest WDG and other pesticides. use a
clear glass quart jar with lid and mix the tank mix ingredients in their relative proportions. Invert the jar
containing the mixture several times and observe the mixture for approximately 1/2 hour. If the mixture
balls-up, forms flakes, sludges, gels, oily films or layers, or other precipitates, it is not compatible. DO
NOT use the tank mix combination.
Application Instructions
Zest WDG provides best results when applied to young, actively growing weeds. Applications made
during warm, moist conditions (70°F or more) and adequate soil moisture both before and after
application maximizes performance.
The degree and duration of control depend on spray coverage, weed spectrum, weed size, growing
conditions before and after treatment, soil moisture, and adjuvant selection.
Zest WDG is rainfast in 4 hours.
Treating weeds that exceed maximum label height or that are under stress may result in incomplete
control. Poor weed control or crop injury may result from applications made to plants under stress from:
 abnormally hot or cold weather
 environmental conditions including drought, water-saturated soils, hail damage, or frost
 disease, insect, or nematode injury
 prior herbicide or carryover from a previous years herbicide application
Severe stress from conditions preceding or immediately following application may also result in crop injury
or poor weed control. Stress affects all weeds, but especially weeds including woolly cupgrass, green and
yellow foxtail, and wild proso millet.

V93 / Zest WDG / MSTR / Amend with edits / 09-27-2022 Page 17
If the crop or grass weeds are under stress, delay application until stress passes and both weeds and
crop resume active growth.
Zest WDG rapidly inhibits the growth of susceptible weeds, reducing weed competition within as little as 6
hours after application. Susceptible plants are controlled in 721 days.
DO NOT exceed labeled application rates. DO NOT tank mix Zest WDG with other products that contain
the same active ingredients as Zest WDG (nicosulfuron) unless the label of either tank mix partner
specifies the maximum rate that may be used.
If the crop or grass weeds are under stress, delay application until stress passes and both weeds and
crop resume active growth.
GROUND APPLICATION
Broadcast Application
 Use a minimum of 15 gallons of water per acre (15 GPA) for best performance. use a minimum of 10
gallons of water per acre (GPA) for light, scattered stands of weeds.
 Overlaps or starting, stopping, slowing, and turning while spraying may result in crop injury.
Band Application
 For band applications, use proportionately less spray mixture, and carefully calibrate the band
applicator to not exceed the labeled rate. Carefully follow the manufacturers instructions for nozzle
type (flat fans), orientation, distance of nozzles from the crop and weeds, spray volumes, calibration
and spray pressure.
AERIAL APPLICATION
 In New York state and California aerial application is not permitted.
 Use nozzle types and arrangements that will provide optimum spray distribution and maximum
coverage at a minimum of 3 GPA.
SPRAYER PREPARATION/CLEANUP
It is important that spray equipment is clean and free of previous pesticide deposits before using Zest
WDG and then properly cleaned out following application. Clean all application equipment before applying
Zest WDG. Follow the cleanup procedures specified on the label of the product previously sprayed. If no
cleanup procedure is provided, use the procedure that follows. Immediately following applications of Zest
WDG, thoroughly clean all mixing and spray equipment to avoid subsequent crop injury.
Note:
 When cleaning spray equipment before applying Zest WDG, read and follow label directions for
proper rinsate disposal of the product previously sprayed.
 Steam cleaning of aerial spray tanks will help to dislodge any visible pesticide deposits.
 When spraying or mixing equipment will be used over an extended period to apply multiple loads of
Zest WDG, partially fill the tank with fresh water at the end of each day of spraying, flush the boom
and hoses, and allow to sit overnight.
Cleanup Procedure
1. Drain the tank and thoroughly hose down the interior surfaces. Flush the tank, hoses, and boom with
clean water for a minimum of 5 min.

V93 / Zest WDG / MSTR / Amend with edits / 09-27-2022 Page 18
2. Partially fill the tank with clean water and add one gallon of household ammonia* (containing 3%
active) for every 100 gallons of water. Finish filling the tank with water, then flush the cleaning
solution through the hoses, boom, and nozzles. Add more water to completely fill the tank and allow
to agitate/recirculate for at least 15 min. Again, flush the hoses, boom, and nozzles with the cleaning
solution, then drain the tank.
3. Repeat Step 2.
4. Remove the nozzles, screens and the end caps of sprayer booms and clean separately in a bucket
containing the cleaning agent and water.
5. Thoroughly rinse the tank with clean water for a minimum of 5 min, flushing the water through the
hoses and boom.
* Equivalent amounts of an alternate strength ammonia solution or a tank cleaner may be used.
CROP ROTATION
Rotational crops vary in their response to low concentrations of Zest WDG remaining in the soil. Zest
WDG dissipates rapidly in warm, acidic, microbiologically active soils.
The amount of Zest WDG which may be present in the soil depends on application rate, soil pH and
organic matter content, elapsed time since application, crop production practices, and environmental
factors.
Injury to rotational crops may occur in high-pH, cold soils if dry weather prevails between application and
rotational crop planting. Consult your local company representative for additional guidelines.
Determine soil pH by laboratory analysis using the 1:1 soil:water suspension method on representative
soil samples taken at 04" depth. Soil pH varies within fields; therefore, base recropping on the highest
soil pH within each field. Consult local extension publications for specified soil sampling procedures.
Observe the following rotational intervals when using Zest WDG at a maximum of 1.33 ounces (0.062 lb

DO NOT tank mix Zest WDG with products containing bentazon or severe corn crop injury may occur.
DO NOT tank mix Zest WDG with foliar-applied organophosphate insecticides including chlorpyrifos and
malathion, etc, as severe crop injury may occur. To avoid crop injury or antagonism, apply these products
at least 7 days before or 3 days after the application of Zest WDG.

DO NOT apply Zest WDG within 45 days of crop emergence where the organophosphate insecticide,
terbufos (including "Counter" brands) was applied since corn crop injury may occur. Applications made
to corn previously treated with chlorpyrifos or other similar organophosphate insecticides may result in
unacceptable crop injury. Any crop injury or yield loss resulting from these applications are the
responsibility of the grower.
DO NOT make a late application of Zest WDG to field corn grown for grain or silage that is taller than 36
inches or that exhibits 10 or more collars (V10), whichever is more restrictive.

DO NOT apply Zest WDG to any white popcorn inbred, or white popcorn hybrid.

DO NOT apply Zest WDG to sweet corn taller than 18 inches or which exhibits 6 or more leaf collars (V6).

DO NOT graze, feed forage, grain or fodder (stover) from corn treated areas to livestock within 30 days
of an Zest WDG application.


FIELD CORN GROWN FOR GRAIN OR SILAGE

Timing to Crop

Zest WDG is registered for use on field corn, high lysine, waxy, white or other food grade corn hybrids.

Zest WDG may be broadcast to corn up to 20" tall (free standing) or that is exhibiting up to and including
6 leaf collars (V6), whichever is more restrictive.

While Zest WDG has a wide application window, research has shown best results are obtained when
applications are made early postemergence when corn and weeds are small. Target applications to corn
that is less than 12 tall for best overall performance.

Timing to Weeds

Apply Zest WDG when grasses are young and actively growing, but before they exceed the sizes
indicated in the Weeds Controlled table with 0.67 ounces (0.031 lb ai) Zest WDG. Treat heavy

V93 / Zest WDG / MSTR / Amend with edits / 09-27-2022 Page 21
infestations of weeds before they become too competitive with the crop, especially where soil moisture
and/or fertility are limited. Zest WDG provides weed control via foliar absorption. Zest WDG only controls
those weeds that have emerged. For later-emerging weeds, a second application or a timely cultivation is
required. Applications made to weeds larger than the size indicated on this label or to weeds under stress
may result in unsatisfactory control. Refer to LATE APPLICATIONS.

On "Roundup Ready" corn, glyphosate including ABUNDITTM Edge (Reg. No 352-922) may be applied
with Zest WDG after weeds emerge but before they reach the maximum size listed on the glyphosate
herbicide label.

On "Liberty Link" corn, glufosinate containing products may be applied with Zest WDG after weeds
emerge but before they reach the maximum size listed on the glufosinate herbicide label.

LATE APPLICATIONS IN FIELD CORN GROWN FOR GRAIN OR SILAGE
Zest WDG may be applied to field corn as a directed postemergence application on corn that is taller than
20 or which has more than 6 collars (whichever occurs first).

 For corn 20 to 36 tall, apply Zest WDG with drop nozzles only and avoid spraying into the whorl of
cornstalks.
 DO NOT apply to corn that is taller than 36" or that exhibits 10 or more collars (V10), whichever is
most restrictive.

Applications made to weeds larger than those listed on this label may vary from complete control to
suppression. Level of control will depend on the weed species, stage of growth, and environmental
conditions.

Choices must be made between the risks that arise from applications made beyond the proper time for
Zest WDG use, and the effects of season long grass competition and/or harvest complications. These
choices must balance risks from improperly timed Zest WDG use that include, but are not limited to:

 Yield loss due to competition: Research indicates competition from foxtail exceeding 4 inches in
height may reduce corn yields. Applications to foxtail and other annual grasses that exceed the sizes
stated on the label increases the risk of yield losses due to prolonged competition with the crop even
though control may be acceptable.
 Incomplete control of grasses beyond labeled size: Applications to grasses that exceed the labeled
sizes can result in reduced control. This incomplete control may reduce corn yield.
 Incomplete grass control due to herbicide stress: grasses under stress from previous herbicide
applications may not be actively growing and susceptible to Zest WDG.
 Ear malformation: Applications of Zest WDG on corn that has 7 to 10 collars (V7 to V10) increases
the potential for ear malfor- mation (pinching). This risk may be greatly reduced, but not eliminated,
by using drop nozzles properly adjusted so as to not apply Zest WDG into the corn whorl.

APPLICATION RATE

Optimum control of the weeds listed can be achieved with 0.67 ounces (0.031 lb ai) of Zest WDG. Weeds
that exceed the listed weed sizes by up to 50% may be partially controlled with rates between 0.67 and
1.33 ounces (0.031 and 0.062 lb ai) of Zest WDG per acre.

Zest WDG may be applied at 0.33  0.67 ounces (0.015  0.031 lb ai) for limited control of certain small
grass weeds. See the table for reduced rates under ADDITIONAL DIRECTIONS for details.

As weeds mature, their sensitivity to Zest WDG decreases. As grassy weeds become mature (more than
3 tillers), they may not reach the size listed below, due to drought or other environmental factors. Treat
grassy weeds that are maturing rapidly before they reach the stages listed below.

POPCORN, FIELD CORN GROWN FOR SEED AND SWEET CORN
Zest WDG may be broadcast or applied with drop nozzles to popcorn or field corn grown for seed that is
less than 20" tall (free-standing) or that exhibits up to and including 5 leaf-collars (V5), whichever is most
restrictive. DO NOT apply to corn that is taller than 20" or that exhibits more than 5 leaf-collars (V5),
whichever is more restrictive.

Many seed companies have tested seed corn inbreds or yellow popcorn hybrids for sensitivity to Zest
WDG and have reported excellent safety. DO NOT apply Zest WDG to any white popcorn inbred, or white
popcorn hybrid unless specifically approved by the seed company. This includes White Dynamite
popcorn.

V93 / Zest WDG / MSTR / Amend with edits / 09-27-2022 Page 23
Zest WDG may be applied to certain sweet corn hybrids grown for fresh markets or under contract for
processing. Applications of Zest WDG may be applied broadcast or with drop nozzles (post-directed) on
sweet corn up to 12 inches tall or up to and including 5 leaf-collars (V5). For sweet corn 12 - 18 inches
tall, apply only with drop nozzles. DO NOT apply to sweet corn taller than 18 inches or those which
exhibit 6 or more leaf-collars (V6), and make only one application of Zest WDG per year.

Sweet corn hybrid sensitivity to Zest WDG is highly variable, and not all hybrids have been tested for crop
sensitivity. Contact your Sales Representative for information on local sweet corn hybrids that have been
evaluated with Zest WDG.

Not all seed corn inbreds, popcorn or sweet corn hybrids have been tested, nor does Corteva have
access to all seed company data. Consequently, to the extent consistent with the law, Corteva is not
responsible for any crop injury arising from the use of Zest WDG on field corn grown for seed, popcorn or
sweet corn. When tank mixing, check the tank mix partner label for sensitivities and instructions for use. It
is the pesticide users responsibility to ensure that all products are registered for the intended use. Read
and follow the applicable restrictions and limitations and directions for use on all product labels involved in
tank mixing. Users must follow the most restrictive directions for use and precautionary statements of
each product in the tank mix.

SEQUENTIAL APPLICATIONS FOLLOWING PREEMERGENCE HERBICIDES

SEQUENTIAL Zest WDG APPLICATIONS
Annual grasses may have more than one flush of emerging seedlings. Also, regrowth of treated annual
grasses may occur due to adverse environmental conditions following application. Perennial grasses may
regrow from underground stems or roots, depending upon environmental conditions. To control grasses
under these conditions, a sequential application of Zest WDG may be necessary.
CULTIVATION
A timely cultivation may be necessary to control suppressed weeds or weeds that emerge after an
application of Zest WDG.

V93 / Zest WDG / MSTR / Amend with edits / 09-27-2022 Page 29
Optimum timing for cultivation is 714 days after Zest WDG application or upon seeing the establishment
of new weeds.
GRAZING/PREHARVEST INTERVALS FOR CORN
DO NOT graze or feed forage, hay, or straw from treated areas to livestock within 30 days of Zest WDG
application.
GRAIN SORGHUM CONTAINING THE INZEN TRAIT
PRODUCT INFORMATION
Apply Zest WDG herbicide to grain sorghum containing the INZEN trait for postemergence control of
certain annual and perennial grass and annual broadleaf weeds.
These application directions are specific for Zest WDG applied to grain sorghum containing the INZEN
trait. DO NOT use Zest WDG on grain sorghum that does not contain the INZEN trait as severe injury
or death will occur.
It is possible that pollen-mediated gene flow from grain sorghum containing the INZEN trait to weedy
relatives, including shattercane and johnsongrass, may contribute to the development of resistance to
ALS herbicides in these species. Plant into fields in which emerged weeds have been controlled by tillage
or nonselective herbicides, including glyphosate. Manage johnsongrass and shattercane growth in road
ditches, fence rows and nearby places so their flowering does not coincide with the INZEN sorghum
trait flowering. DO NOT use Zest WDG on grain sorghum containing the INZEN trait in fields known to
have ALS-resistant shattercane or johnsongrass. Adherence to the Corteva Stewardship Program,
including completion of the certification program and following the Best Management Practices is
necessary to reduce the risk of the development of resistance to ALS herbicides in weedy relatives.

APPLICATION DIRECTIONS

WEED RESISTANCE IN GRAIN SORGHUM CONTAINING THE INZEN TRAIT
The continued availability and utility of this product depends on the successful management of the weed
resistance program; therefore, it is very important to perform the following activities.
The following steps are provided to aid in the prevention of developing weeds resistant to this product:
 Scout fields before application to ensure herbicides and rates will be appropriate for the weed species
and weed sizes present.
 Apply the maximum specified labeled use rates of Zest WDGACCENT® for the most difficult to
control weeds in the field at the specified time (correct weed size) or when applications are made
under challenging environmental conditions to minimize weed escapes.
 Scout fields after application to detect weed escapes or shifts in weed species.
 Report any incidence of non-performance of this product on a weed species listed in the Weeds
Controlled section to your Corteva retailer, representative or 1-800-258-3033
 Suspected herbicide-resistant weeds may be identified by these indicators:
 Failure to control a weed species normally controlled by the herbicide at the dose applied,
especially if control is achieved on adjacent weeds;
 A spreading patch of non-controlled plants of a particular weed species; and
 Surviving plants mixed with controlled individuals of the same species.
Additionally, users need to follow as many of the following herbicide resistance management practices as
practical:

V93 / Zest WDG / MSTR / Amend with edits / 09-27-2022 Page 31
 Use a broad spectrum soil-applied herbicide with other modes of action as a foundation in a weed
control program.
 Utilize sequential applications of herbicides with alternative modes of action.
 Rotate the use of this product with non-Group 2 herbicides.
 Incorporate non-chemical weed control practices, such as mechanical cultivation, crop rotation, cover
crops and weed- free crop seeds, as part of an integrated weed control program.
 Thoroughly clean plant residues from equipment before leaving fields suspected to contain resistant
weeds.
 Avoid using any other Group 2 herbicide within a single growing season unless in conjunction with
another mode of action herbicide with overlapping spectrum.
 Manage weeds in and around fields, during and after harvest to reduce weed seed production.
Contact the local agricultural extension service, company representative, agricultural retailer or crop
consultant for further guidance on weed control practices as needed.
APPLICATION RATE
Apply 0.67 to 1.33 ounces (0.031 to 0.062 lb ai) of Zest WDG by ground or by air per acre per application
to grain sorghum containing the INZEN trait.

APPLICATION TIMING TO CROP

Apply Zest WDG to emerged grain sorghum containing the INZEN trait that is up to 20 inches tall.
Applications made to 4-20 inch tall grain sorghum approximately five leaf stage (growth stage 2) to flag
leaf visible (growth stage 4) are advised for best crop resistance. DO NOT apply to grain sorghum taller
than 20 inches.

APPLICATION TIMING TO WEEDS

Apply Zest WDG when grasses are young and actively growing, but before they exceed the sizes
indicated in the table WEEDS CONTROLLED IN INZEN GRAIN SORGHUM with 0.67 ounces (0.031 lb
ai) Zest WDG. Treat heavy infestations of weeds before they become too competitive with the crop,
especially where soil moisture and/or fertility are limited. Zest WDG provides weed control via foliar
absorption. Zest WDG only controls those weeds that have emerged. For later-emerging weeds, a
second application or a timely cultivation is required. Applications made to weeds larger than the size
indicated on this label or to weeds under stress may result in unsatisfactory control.

As weeds mature, their sensitivity to Zest WDG decreases. As grassy weeds become mature (more than
3 tillers), they may not reach the size listed below, due to drought or other environmental factors. Treat
grassy weeds that are naturally maturing rapidly before they reach the stages listed in the table Weeds
controlled with 0.67 ounces (0.031 lb ai) Zest WDG.

SEQUENTIAL APPLICATIONS

In the event that a subsequent flush of weeds or regrowth of previously treated weeds occur, a second
application of Zest WDG may be applied.

WEEDS CONTROLLED IN INZEN GRAIN SORGHUM

* Refer to Specific Weed Instructions Section of this Label
SPECIFIC WEED INSTRUCTIONS
Crabgrass (large): Requires the application of a soil applied herbicide that is effective in controlling large
crabgrass, including CINCH® (AI: S-metolachlor; Reg. No. 352-625) or CINCH® ATZ (AI: atrazine + S-
metolachlor; Reg. No. 352-624), followed by the post emergence application of Zest WDG herbicide at 0.67
ounces (0.031 lb ai)/acre plus crop oil concentrate (COC) and ammonium nitrogen fertilizer. Adequate
moisture is required after application of these soil applied herbicides to provide activation for weed control
to occur. Cultivation or retreatment with Zest WDG plus COC and ammonium nitrogen fertilizer may be
required for additional control of later emerging grasses. Zest WDG will not control or suppress smooth
crabgrass.

Sandbur (field, longspine): Requires the use of COC plus ammonium nitrogen fertilizer. Cultivation or
re-treatment may be required.

SPRAY ADJUVANTS FOR USE IN INZEN TRAIT GRAIN SORGHUM

Applications of Zest WDG must include either a crop oil concentrate or a nonionic surfactant. If another
herbicide is tank mixed with Zest WDG, select adjuvants authorized for use with both products. Products
must contain only EPA-exempt ingredients (40CFR 1001).

Petroleum Crop Oil Concentrate (COC)

 Petroleum-based crop oil concentrates are the preferred adjuvant systems in arid areas.
 Apply up to 1% v/v (1 gallon per 100 gallons spray solution) or 2% under arid conditions.
 Oil adjuvants must contain at least 80% high quality, petroleum (mineral) or modified vegetable seed
oil with at least 15% surfactant emulsifiers.
 For aerial applications apply 0.5% v/v (2 quarts product per 100 gallons spray solution).

Nonionic Surfactant (NIS)

 Apply up to 0.25% v/v (1 quart per 100 gallons spray solution) or 0.5% v/v under arid conditions.

TANK MIXING

Zest WDG herbicide may be tank mixed with 2,4-D low volatile-ester, dicamba, atrazine, "Starane Ultra"
(AI: fluroxypyr; Reg. No. 62719-577), and ALLY XP (AI: metsulfuron methyl; Reg, No. 279-9575[352-
435]) herbicides registered for use in grain sorghum. DO NOT use COC (crop oil concentrate) when tank
mixing with 2,4-D or dicamba. When tank mixing with 2,4-D or dicamba expect some crop response in the
form of rolled leaves, leaning, brace root malformation and/or brittle stems. DO NOT apply 2,4-D or
dicamba if this potential for injury is not acceptable. DO NOT tank mix with Huskie (AI: pyrasulfotole +
bromozynilbromoxynil ocatanoate + bromoxynil heptanoate; Reg. No., 267-1023) as significant grass
antagonism, and crop injury can result. It is the pesticide user's responsibility to ensure that all products
are registered for the intended use. Read and follow the applicable restrictions and limitations and
directions for use on all product labels involved in tank mixing. Users must follow the most restrictive
directions for use and precautionary statements of each product in the tank mixture. If those instructions
conflict with this label, DO NOT tank mix the herbicide with Zest WDG.

CULTIVATION

A timely cultivation may be necessary to control suppressed weeds or weeds that emerge after an
application of Zest WDG.

Optimum timing for cultivation is 714 days after Zest WDG application or upon seeing the establishment
of new weeds.

GRAZING / PREHARVEST INTERVALS FOR GRAIN SORGHUM CONTAINING THE INZEN TRAIT

Forage may be cut and livestock may be grazed once the crop has reached the mature forage stage (soft
dough growth stage 7). Grain and stover may be harvested once the crop has reached the mature grain
stage (physiological maturity growth stage 9).

CROP ROTATION[WS3][AJ4]
Rotational crops vary in their response to low concentrations of ACCENT® remaining in the soil.
ACCENT® dissipates rapidly in warm, acidic, microbiologically active soils.
The amount of ACCENT® which may be present in the soil depends on application rate, soil pH and
organic matter content, elapsed time since application, crop production practices, and environmental
factors.
Injury to rotational crops may occur in high-pH, cold soils if dry weather prevails between application and
rotational crop planting. Consult your local company representative for additional guidelines.
Determine soil pH by laboratory analysis using the 1:1 soil:water suspension method on representative
soil samples taken at 04" depth. Soil pH varies within fields; therefore, base recropping on the highest
soil pH within each field. Consult local extension publications for specified soil sampling procedures.
Observe the following rotational intervals when using ACCENT® at a maximum of 1.33 ounces (0.062 lb

(HLB) greater than 12.
Ammonium Nitrogen Fertilizer

V93 / Zest WDG / MSTR / Amend with edits / 09-27-2022 Page 37
 Use 2 quarts/acre of a high-quality urea ammonium nitrate (UAN), including 28%N or 32%N, or 2
pounds/acre of a spraygrade ammonium sulfate (AMS). Use 4 quarts/acre UAN or 4 pounds/acre
AMS under arid conditions.
 DO NOT use liquid nitrogen fertilizer as the total carrier solution.
Special Adjuvant Types
 Combination adjuvant products may be used at doses that provide the required amount of NIS, COC,
MSO and/or ammonium nitrogen fertilizer. Consult product literature for use rates and restrictions.
 In addition to the adjuvants specified above, other adjuvant types may be used if they provide the
same functionality and have been evaluated and approved by Corteva Product Management.
MIXING INSTRUCTIONS
Select a spray volume that will ensure thorough coverage and a uniform spray pattern. If tank mixing with
other herbicides, always consult the label of the tank mix partner(s) for minimum spray volume
requirements and apply the tank mixture using a water volume advised for all products.
1. Fill the tank 1/4 to 1/3 full of water.
2. While agitating, add the required amount of ACCENT®.
3. Continue agitation until the ACCENT® is fully dispersed, at least 5 minutes.
4. Once the ACCENT® is fully dispersed, maintain agitation and continue filling tank with water.
Thoroughly mix ACCENT® with water before adding any other material.
5. If tank mixing ACCENT® with another herbicide, follow this mixing order: dry flowables and soluble
granules, followed by liquids, then oil dispersions (od) or emulsifiable concentrates (ec). Maintain
continuous agitation.
6. As the tank is filling, add the required spray adjuvants (crop oil concentrate, nonionic surfactant, or
ammonium nitrogen fertilizer).
7. If the mixture is not continuously agitated, settling will occur. If settling occurs, thoroughly re-agitate
before using.
Apply ACCENT® spray mixture within 24 hours of mixing to avoid product degradation.
If ACCENT® and a tank mix partner are to be applied in multiple loads, pre-slurry the ACCENT® in
clean water prior to adding to the tank. This will prevent the tank mix partner from interfering with the
dissolution of the ACCENT®.
TANK MIX COMPATIBILITY TESTING
Perform a jar test prior to tank mixing to ensure compatibility of ACCENT® and other pesticides. use a
clear glass quart jar with lid and mix the tank mix ingredients in their relative proportions. Invert the jar
containing the mixture several times and observe the mixture for approximately 1/2 hour. If the mixture
balls-up, forms flakes, sludges, gels, oily films or layers, or other precipitates, it is not compatible. DO
NOT use the tank mix combination.
ENVIRONMENTAL CONDITIONS AND BIOLOGICAL ACTIVITY
ACCENT® provides best results when applied to young, actively growing weeds. Applications made
during warm, moist conditions (70°F or more) and adequate soil moisture both before and after
application maximizes performance.
The degree and duration of control depend on spray coverage, weed spectrum, weed size, growing
conditions before and after treatment, soil moisture, and adjuvant selection.
ACCENT® is rainfast in 4 hours.

Treating weeds that exceed maximum label height or that are under stress may result in incomplete
control. Poor weed control or crop injury may result from applications made to plants under stress from:
 abnormally hot or cold weather
 environmental conditions including drought, water-saturated soils, hail damage, or frost
 disease, insect, or nematode injury
 prior herbicide or carryover from a previous years herbicide application
Severe stress from conditions preceding or immediately following application may also result in crop injury
or poor weed control. Stress affects all weeds, but especially weeds including woolly cupgrass, green and
yellow foxtail, and wild proso millet.
If the crop or grass weeds are under stress, delay application until stress passes and both weeds and
crop resume active growth.
ACCENT® rapidly inhibits the growth of susceptible weeds, reducing weed competition within as little as
6 hours after application. Susceptible plants are controlled in 721 days.
DO NOT exceed labeled application rates. DO NOT tank mix ACCENT® with other products that contain
the same active ingredients as ACCENT® (nicosulfuron) unless the label of either tank mix partner
specifies the maximum rate that may be used.
If the crop or grass weeds are under stress, delay application until stress passes and both weeds and
crop resume active growth.
SPRAYER PREPARATION/CLEANUP
It is important that spray equipment is clean and free of previous pesticide deposits before using
ACCENT® and then properly cleaned out following application. Clean all application equipment before
applying ACCENT®. Follow the cleanup procedures specified on the label of the product previously
sprayed. If no cleanup procedure is provided, use the procedure that follows. Immediately following
applications of ACCENT®, thoroughly clean all mixing and spray equipment to avoid subsequent crop
injury.
Note:
 When cleaning spray equipment before applying ACCENT®, read and follow label directions for
proper rinsate disposal of the product previously sprayed.
 Steam cleaning of aerial spray tanks will help to dislodge any visible pesticide deposits.
 When spraying or mixing equipment will be used over an extended period to apply multiple loads of
ACCENT®, partially fill the tank with fresh water at the end of each day of spraying, flush the boom
and hoses, and allow to sit overnight.
Cleanup Procedure
1. Drain the tank and thoroughly hose down the interior surfaces. Flush the tank, hoses, and boom with
clean water for a minimum of 5 min.
2. Partially fill the tank with clean water and add one gallon of household ammonia* (containing 3%
active) for every 100 gallons of water. Finish filling the tank with water, then flush the cleaning
solution through the hoses, boom, and nozzles. Add more water to completely fill the tank and allow
to agitate/recirculate for at least 15 min. Again, flush the hoses, boom, and nozzles with the cleaning
solution, then drain the tank.
3. Repeat Step 2.

V93 / Zest WDG / MSTR / Amend with edits / 09-27-2022 Page 39
4. Remove the nozzles, screens and the end caps of sprayer booms and clean separately in a bucket
containing the cleaning agent and water.
5. Thoroughly rinse the tank with clean water for a minimum of 5 min, flushing the water through the
hoses and boom.
* Equivalent amounts of an alternate strength ammonia solution or a tank cleaner may be used.
