Product Name: Zest WDG EPA Registration Number: 352-560 Application Date: 11/9/2022 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

Page 2 of 2 EPA Reg. No. 352-560 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- arias.francisco@epa.gov.

USER SAFETY RECOMMENDATIONS 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.

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.

V93 / Zest WDG / MSTR / Amend with edits / 09-27-2022 Page 13 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 additive’s 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 year’s 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 7–21 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 manufacturer’s 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 0–4" 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 ai): Zest WDG ROTATIONAL CROP GUIDELINE - 1 No soil pH restrictions Rotational Crop Interval in Months Corn (field, pop, seed, sweet*) Anytime Soybeans0.5 (15 days) Cereals, spring (barley, oats, rye, wheat) 8 Cereals, winter (barley, oats, rye, wheat) 4 Cotton 10 Dry beans, Peas, Snap beans 10 Alfalfa** 12 Red Clover** 12 Sorghum 10 Sorghum (hybrids containing ALS-resistant traits) 18 Other Crops See Rotational Crop guidelines 2 and 3

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.

V93 / Zest WDG / MSTR / Amend with edits / 09-27-2022 Page 22 When applied as directed, Zest WDG will control the following weeds: Weeds controlled with 0.67 ounces (0.031 lb ai) Zest WDG.

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 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 mix.

Other Tank Mixtures

Other than the exceptions noted, and in addition to the tank mix partners and rates indicated above, Zest WDG may be tank mixed or followed with sequential applications of other products registered for use in field corn. Applications of full or reduced rates of other products registered for use in corn provided:

The tank mix product is labeled for the same timing, method of application, adjuvants, and use restrictions as Zest WDG. The tank mixture is not specifically prohibited on the label of the tank mix product. The tank mix combination is compatible as determined by a “jar test” described in the TANK MIX COMPATIBILITY TESTING section below.

Weed control and crop response with tank mixtures not specified in this label are the responsibility of the user and manufacturer of the tank mix product. A corn plant’s predisposition to develop fused tissue emerging from the whorl (rattail) after the V-11 stage may increase when a product containing dicamba (i.e. “Clarity”, “Marksman”) is applied to small corn under early stressful conditions. be aware of this when applying tank mixes with dicamba to small corn (V- 3 stage or smaller) under stressful conditions. See ENVIRONMENTAL CONDITIONS for a description of these stressful conditions.

To avoid crop injury or antagonism, apply the products indicated below at least seven days before or three days after the application of Zest WDG.

DO NOT tank mix Zest WDG with “Basagran” (AI: bentazon; Reg. Nos. 66330-413, 7969-112) and “Laddok” (AI: bentazon + atrazine; Reg. No. 51036-415) or severe crop injury may occur. DO NOT tank mix Zest WDG with 2,4-D -containing products as severe grass control antagonism may occur. DO NOT tank mix Zest WDG with foliar-applied organophosphate insecticides including “Lorsban” brands (AI: chloripyrifos; Reg.

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. 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 7–14 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.

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. Surfactant products must contain at least 60% nonionic surfactant with a hydrophilic/lipophilic balance (HLB) greater than 12.

Ammonium Nitrogen Fertilizer

Use 2 quarts/acre of a high-quality urea ammonium nitrate (UAN), including 28%N or 32%N, or 2 pounds/acre of a spray- grade 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

V93 / Zest WDG / MSTR / Amend with edits / 09-27-2022 Page 33 Combination adjuvant products may be used at doses that provide the required amount of NIS, COC, MSO (modified seed oils) and/or ammonium nitrogen fertilizer.

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 7–14 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 0–4" 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 ai): ACCENT® ROTATIONAL CROP GUIDELINE - 1

SPRAY ADJUVANTS FOR USE IN FIELD CORN GROWN FOR GRAIN & SEED, POPCORN, & SWEET CORN Applications of ACCENT® must include either a crop oil concentrate or a nonionic surfactant. In addition, an ammonium nitrogen fertilizer must be used unless specifically prohibited by tank mix partner labeling. Crop oil concentrate plus ammonium nitrogen fertilizer is the preferred adjuvant system for activity on difficult to control species including woolly cupgrass, quackgrass, sandbur and wirestem muhly. If another herbicide is tank mixed with ACCENT®, select adjuvants authorized for use with both products. Products must contain only EPA-exempt ingredients (40 CFR 1001). 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. When applied in tank mix combination with a glyphosate containing product that contains a built-in adjuvant, ensure the total adjuvant load is equivalent to the directions on this label. Crop Oil Concentrate (COC) - Petroleum or Modified Seed Oil (MSO) Apply up to 1% v/v (1 gallon per 100 gallons spray solution) under arid conditions. MSO adjuvants may be used up to 0.5% v/v (0.5 gallons per 100 gallons spray solution) if specifically noted on adjuvant product labeling or if specified on local company product literature or service policies. Oil adjuvants must contain at least 80% high quality, petroleum (mineral) or modified vegetable seed oil with at least 15% surfactant emulsifiers. Nonionic Surfactant (NIS) Apply up to 0.25% v/v (1 quart per 100 gallons spray solution) under arid conditions. Surfactant products must contain at least 60% nonionic surfactant with a hydrophilic/lipophilic balance (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.

V93 / Zest WDG / MSTR / Amend with edits / 09-27-2022 Page 38 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 year’s 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 7–21 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.
