When handlers use closed systems, enclosed cabs, or ai rcraft in a manner that meets the requirements listed in the Worker Protection Standard (WPS) for agricultural pesti cides [40 CFR 170.607(d-f)], the handler PPE requirements may be reduced or modified as specified in the WPS.

User Safety Recommendations Users should: x Remove clothing/PPE immediately if pesticide gets inside. Then wash thoroughly and put on clean clothing. x Remove PPE immediately after handling this pr oduct. 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 wash water or rinsate.

Groundwater Advisory S-metolachlor 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.

Metribuzin is a chemical which can travel (seep or leach) through soil and can contaminate groundwater which may be used as drinking water. Metribuzin has been found in groundwater as a result of agricultural use. Users are advised not to apply metribuzin where the water table (groundwater) is close to the surface and where the soils are very permeable, i.e., well-drained soils such as loamy sands. Your local agricultural agencies can provide further information on the type of soil in your area and the location of groundwater.

Page 3 of 21

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 weeks or months 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 S-metolachlor from runoff water and sediment. Runoff of this product will be reduced by av oiding applications when rainfall or irrigation is expected to occur within 48 hours.

Non-target Organism Advisory This product is toxic to plants and may adversely im pact the forage and habitat of non-target organisms, including pollinators, in areas adjacent to the treated site. Protect the forage and habitat of non-target organisms by following label directions intended to minimize spray drift.

Mixing/Loading Instructions Care must be taken when using this product to prevent back-siphoning into wells, spills, or improper disposal of excess pesticide, spray mixtures, or rinsate.

PRODUCT INFORMATION AGH19016 is a soil applied, pre-emergent herbicide containing two active ingredients with different modes of action, which assists in the management of herbicide resistance.

Do not apply under conditions which favor runoff or wind erosion of soil containing this product to non- target areas.

To prevent off-site movement due to runoff or wind erosion: x Avoid treating powdery dry or light sand soils when conditions are favorable for wind erosion. Under these conditions, the soil surface should first be settled by rainfall or irrigation. x Do not apply to impervious substrates, such as paved or highly compacted surfaces. x Do not use tailwater from the first flood or furrow irrigation of treated fields to treat non-target crops, unless at least ½ inch of rainfall has occurred between application and the first irrigation.

Mixing Instructions Prepare no more spray mixture than is needed for the immediate operation. Thoroughly clean the spray equipment before using AGH19016. Vigorous agitation is necessary to maintain uniformity of the spray mixture. Maintain maximum agitation throughout the spraying operation. Do not allow spray mixture to stand overnight in the spray tank. Flush the spray equipment thoroughly following each use and apply the rinsate to a previously treated area.

Page 5 of 21

Application in Water or Fluid Fertilizers AGH19016 Alone: Add 1/3 of the required amount of water or fluid fertilizer to the spray or mixing tank. With the agitator running, add AGH19016 into the spray tank. Continue agitation while adding the remainder of the water or fluid fertilizer. Begin application of the spray solution after the AGH19016 has completely dispersed in the water or fluid fertilizer. Maintain agitation until all of the mixture has been applied.

Tank Mixtures This product may be tank mixed with other products at appropriate rates as long as tank mixing is not prohibited by the label(s) of the tank mix partner products, or as otherwise noted within the specific crop use directions for this product, and the tank mix partner products are labeled for the timing and method of application for the use site to be treated. Do not exceed any label dosage rates. It is the pesticide user’s responsibility to ensure that all products in the mixtures are registered for the intended use. Read and follow the applicable restrictions and 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 you have no previous experience mixing these produc ts under your conditions, perform a compatibility test before attempting large-scale mixing (see the Compatibility Test section of this label).

Mixing Instructions (AGH19016 + Tank Mix Partner): Add 1/3 of the required amount of water or fluid fertilizer to the mix tank. Start the agitator running before adding any tank mix partners. In general, add tank mix partners in this order: products packaged in water-soluble packaging, wettable powders, wettable granules (dry flowables), liquid flowables, liquids such as AGH19016, and emulsifiable concentrates.

Always allow each tank mix partner to become fully dispersed before adding the next product. Provide sufficient agitation while adding the remainder of the water. Maintain agitation until all of the mixture has been applied.

When using AGH19016 in tank mixtures with products packaged in water-soluble packaging:

1. Add all products in water-soluble packaging to the tank and mix with plain water before any other tank mix partner, including AGH19016. Allow the wa ter-soluble packaging to completely dissolve and the product(s) to completely disperse before adding any other tank mix partner to the tank.
2. Water-soluble packets will not properly dissolve in most spray solutions that contain fluid fertilizers.

AGH19016 is compatible with most common tank mix partners. However, the physical compatibility of AGH19016 with tank mix partners should be tested before use. To determine the physical compatibility of AGH19016 with other products, use a jar test, as described below.

Compatibility Test A jar test is recommended before tank mixing to ensure compatibility of AGH19016 with other pesticides. The following test assumes a spray volume of 25 gal./A. For other spray volumes, make appropriate changes in the ingredients.

Note: Nitrogen solutions or complete fluid fertilizers may replace all or part of the water in the spray. Because liquid fertilizers vary, even within the same analysis, always check compatibility with pesticide(s) before use. Incompatibility of tank mixtures is more common with suspensions of fertilizer and pesticides.

Test Procedure

1. Add 1.0 pt. of carrier (fertilizer or water) to each of 2 one qt. jars with tight lids. Note: Use the same source of water that will be used for the tank mix and conduct the test at the temperature the tank mix will be applied.
2. To one of the jars, add ¼ tsp. or 1.2 milliliters of a compatibility agent approved for this use (¼ tsp. is equivalent to 2.0 pt./100 gal. spray). Shake or stir gently to mix.

Page 6 of 21

3. To both jars, add the appropriate amount of pesticide(s) in their relative proportions based on label rates. If more than one pesticide is used, add them separately with dry pesticides first, flowables next, and emulsifiable concentrates last. After each addition, shake or stir gently to thoroughly mix.
4. After adding all ingredients, put lids on and tighten, and invert each jar ten times to mix. Let the mixtures stand 15-30 minutes and then look for separat ion, large flakes, precipitates, gels, heavy oily film on the jar, or other signs of incompatibility. Determine if the compatibility agent is needed in the spray mixture by comparing the two jars. If either mixture separates, but can be remixed readily, the mixture can be sprayed as long as good agitation is used. If the mixtures are incompatible, test the following methods of improving compatibility: (a) Slurry the dry pesticide(s) in water before addition, or (b) add ½ the compatibility agent to the fertilizer or water and the other ½ to the emulsifiable concentrate or flowable pesticide before addition to the mixture. If incompatibility is still observed, do not use the mixture.
5. After compatibility testing is complete, dispose of any pesticide wastes in accordance with the Storage and Disposal section in this label.

Ground Application Apply AGH19016 alone or in tank mixtures by ground equipment in a minimum of 10 gallons of spray mixture per acre, unless otherwise specified.

Use sprayers that provide accurate and uniform application. Calibrate the sprayer before use at the beginning of the season. For AGH19016 tank mixtures with wettable powder or dry flowable formulations, screens and strainers should be no finer than 50-mesh.

Calculate the amount of herbicide needed for band treatment by the formula: Band width in inches X broadcast rate per acre = amount needed per acre of field Row width in inches

Center Pivot Irrigation Application If applying through chemigation, apply this product only through a center pivot irrigation system. Do not apply this product through any other type of irrigation syste m. Crop injury, lack of effectiveness, or illegal pesticide residues in the crop can result from non- uniform distribution of tr eated water. If you have questions about calibration, contact State Extensi on specialists, equipment manufacturers, or other experts. Do not connect an irrigation system (including greenhouse systems) used for pesticide application to a public water system, unless the pesticide label-prescribed safety devices for public water systems are in place. A person knowledgeable of the chemigation system and responsible for its operation, or under the supervision of the responsible person, shall shut the system down and make necessary adjustments should the need arise.

Operating Instructions x The system must contain a functional check-valve, vacuum relief valve, and low pressure drain appropriately located on the irrigation pipeline to prevent water- source contamination from backflow. x The pesticide injection pipeline must contain a functional, automatic, quick-closing check-valve to prevent the flow of fluid back toward the injection pump. x The pesticide injection pipeline must also contain a functional, normally closed, solenoid-operated valve located on the intake side of the injection pump and connected to the system interlock to prevent fluid from being withdrawn from the supply tank when the irrigation system is either automatically or manually shut down. x The system must contain functional interlocking controls to automatically shut off the pesticide injection pump when the water pump motor stops. x The irrigation line or water pump must include a functional pressure switch which will stop the water pump motor when the water pressure decreases to the point where pesticide distribution is adversely affected.

Page 7 of 21

x Systems must use a metering pump, such as a positive displacement injection pump (e.g., diaphragm pump or piston pump), effectively designed and constructed of materials that are compatible with pesticides and capable of being fitted with a system interlock. x Do not apply when wind speed favors drift beyond the area intended for treatment. x Prepare a mixture with a minimum of 1-part water to 1-part herbicide(s) and inject this mixture into the center pivot system. Injecting a larger volume of a more dilute mixture per hour will usually provide more accurate calibration of metering equipment. Maintain sufficient agitation to keep the herbicide in suspension. x Meter into irrigation water during entire period of water application. x Apply in ½ - 1 inch of water. Use the lower water volume (½ inch) on coarse-textured soils and the higher volume (1 inch) on fine-textured soils. More than 1 inch of water at application may reduce weed control by moving the herbicide below the effective zone in the soil.

Precaution for center pivot applications: Where sprinkler distribution patterns do not overlap sufficiently, unacceptable weed control may resul t. Where sprinkler distribution patterns overlap excessively, crop injury may result.

Aerial Application Apply AGH19016 in water using a minimum spray volume of 2 gal./A. Avoid application under conditions where uniform coverage cannot be obtained or where excessive spray drift may occur. Make applications at a maximum height of 10 ft. above the crop canopy.

Do not apply this product in a way that will contact workers or other persons, either directly or through drift. Only protected handlers may be in the area during application.

Spray Drift Management

Mandatory Spray Drift Management Aerial Applications: x Do not release spray at a height greater than 10 ft above the ground or vegetative canopy, unless a greater application height is necessary for pilot safety. x For applications prior to the emergence of crops and target weeds, applicators are required to select the nozzle and pressure that deliver coarse or coarser droplets (ASABE S641). x For all other applications, applicators are required to select the nozzle and pressure that deliver medium or coarser droplets (ASABE S641). x Nozzles must always point backward parallel with the air stream and never be pointed downwards more than 45 degrees. x If the wind speed is 10 miles per hour or less, applicators must use ½ swath displacement upwind at the downwind edge of the field. When the wind speed is between 11-15 miles per hour, applicators must use ¾ swath displacement upwind at the downwind edge of the field. x Do not apply when wind speeds exceed 15 mph at the application site. If the wind speed is greater than 10 mph, the boom length must be 65% or less of the wingspan for fixed wing aircraft and 75% or less of the rotor diameter for helicopters. Otherwise, the boom length must be 75% or less of the wingspan for fixed-wing aircraft and 90% or less of the rotor diameter for helicopters. x Do not apply during temperature inversions. Ground Boom Applications: x User must only apply with the release height recommended by the manufacturer, but no more than 4 feet above the ground or crop canopy. x Applicators are required to select the nozzle and pressure that deliver medium or coarser droplets (ASABE S572). x Do not apply when wind speeds exceed 15 miles per hour at the application site. x Do not apply during temperature inversions.

Page 8 of 21

Boomless Ground Applications: x Applicators are required to select the nozzle and pressure that deliver medium or coarser droplets (ASABE S572). x Do not apply when wind speeds exceed 15 miles per hour at the application site. x Do not apply during temperature inversions.

Spray Drift Advisories THE APPLICATOR IS RESPONSIBLE FOR AVOIDING OFF-SITE SPRAY DRIFT. BE AWARE OF NEARBY NON-TARGET SITES AND ENVIRONMENTAL CONDITIONS. Importance of Droplet Size An effective way to reduce spray drift is to apply large droplets. Use the largest droplets that provide target pest control. While applying larger droplets will reduce spray drift, the potential for drift will be greater if applications are made improperly or under unfavorable environmental conditions. Controlling Droplet Size – Ground Boom x Volume - 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. x Pressure - Use the lowest spray pressure recommended for the nozzle to produce the target spray volume and droplet size. x Spray Nozzle - Use a spray nozzle that is designed for the intended application. Consider using nozzles designed to reduce drift. Solid stream nozzles oriented straight back produce the largest droplets and the lowest drift. x Number of nozzles - Use the minimum number of nozzles that provide uniform coverage. x Nozzle Orientation - Orienting nozzles so that the spray is released parallel to the airstream produces larger droplets than other orientations and is the recommended practice. Significant deflection from horizontal will reduce droplet size and increase drift potential. Controlling Droplet Size – Aircraft x Adjust Nozzles - Follow nozzle manufacturers’ recommendations for setting up nozzles. x Generally, to reduce fine droplets, nozzles should be oriented parallel with the airflow in flight.

Boom Height – Ground Boom 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. Do not release spray at a height greater than 10 feet above the ground or vegetative crop canopy, unless a greater application height is required for aircraft safety. Making applications at the lowest height that is safe reduces exposure of droplets to evaporation and wind. Swath Adjustment When applications are made with a crosswind, the swath will be displaced downward. Therefore, on the up and downwind edges of the field, the applicator must compensate for this displacement by adjusting the path of the aircraft upwind. Swath adjustment distance should increase, with increasing drift potential (higher wind, smaller drops, etc.) Shielded Sprayers Shielding the boom or individual nozzles can reduce sp ray 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.

Page 9 of 21

Temperature Inversions Drift potential is high during a temperature inversio n. 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. Wind Drift potential generally increases with wind speed. AVOID APPLICATIONS DURING GUSTY WIND CONDITIONS. Drift potential is lowest between wind speeds of 2-10 mph. However, many factors, including droplet size and equipment type determine drift potential at any given speed. Application should be avoided below 2 mph due to variable wind direction and high inversion potential. NOTE: Local terrain can influence wind patterns. Every applicator should be familiar with local wind patterns and how they affect spray drift. Sensitive Areas The pesticide should only be applied when the potential for drift to adjacent sensitive areas (e.g. residential areas, bodies of water, known habitat for threatened or endangered species, non-target crops) is minimal (e.g. when wind is blowing away from the sensitive areas). Boomless Ground Applications Setting nozzles at the lowest effective height will help to reduce the potential for spray drift. Handheld Technology Applications: Take precautions to minimize spray drift. Cleaning Equipment After Application Because some non-labeled crops are sensitive to low rates of AGH19016, special attention must be given to cleaning equipment before spraying a crop other than those registered for use and on this label. Mix only as much spray solution as needed. Immediately after spraying, clean equipment thoroughly using the following procedure:

1. Flush tank, hoses, boom, and nozzles with clean water.
2. Prepare a cleaning solution of one gal. of household ammonia per 50 gal. of water. Many commercial spray tank cleaners may be used as well. Consult your Winfield Solutions, LLC representative for a partial listing of approved tank cleaners and more information about proper tank cleaning procedures. Do not use chlorine-based cleaners.
3. When available, use a pressure washer to clean the inside of the spray tank with this solution. Take care to wash all parts of the tank, including the inside top surface. Completely fill the sprayer with the cleaning solution to ensure contact of the cleaning solution with all internal surfaces of the tank and plumbing. Start agitation in the sprayer and thoroughly re-circulate the cleaning solution for at least 15 minutes . All visible deposits must be removed from the spraying system.
4. Flush hoses, spray lines, and nozzles for at least one minute with the cleaning solution.
5. Dispose of rinsate from steps 1 - 3 as described under the Environmental Hazards section of the Precautionary Statements.
6. Repeat steps 2 - 5.
7. Remove nozzles, screens, and strainers and clean separately in the ammonia cleaning solution after completing the above procedures.
8. Rinse the complete spraying system with clean water.

Impregnation Onto Dry Bulk Granular Fertilizers Many dry bulk granular fertilizers may be impregnated or coated with AGH19016 and used to control weeds. When applying AGH19016 with dry bulk fertilizers, follow all directions for use, restrictions and precautions

Page 10 of 21

on the AGH19016 label regarding target crops, rates per acre, soil texture, application methods, and rotational crops.

Complying with all individual state regulations relating to dry bulk granular fertilizer blending, registration, labeling, and application is the responsibility of the individual and/or company selling the herbicide/fertilizer mixture.

Prepare the herbicide/fertilizer mixture by using any closed drum, belt, ribbon, or other commonly used dry bulk fertilizer blender. Nozzles used to spray AGH19016 onto the fertilizer must be spaced to provide uniform spray coverage. Take care to aim the spray onto the fertilizer only, avoiding the walls of the blender.

If the herbicide/fertilizer mixture is too wet, add a highly absorptive material, such as granular clay or diatomaceous earth materials, to obtain a dry, free-flowing mixture. Add absorptive materials only after the herbicide has been thoroughly blended into the fertilizer mixture. Best application results will be obtained by using a granule of 6/30 particle size or of a size similar to that of the fertilizer materials being used. Generally, less than 2% by weight of absorptive material will be needed. Avoid using more than 5% absorptive material by weight.

Calculate the amount of AGH19016 to be used by the following formula:

2,000 X pt. of AGH19016 per acre = pt. of AGH19016 per ton of fertilizer lbs. of fertilizer per acre

Pneumatic (Compressed Air) Application High humidity, high urea concentrations, low fertilizer use rates, and dusty fertilizer may cause fertilizer mixtures to build up or plug the distributor head, air tubes, or nozzle deflector plates. To minimize buildup, premix AGH19016 with Aromatic 200 at a rate of 2. 0 - 2.5 pt./gal. of AGH19016. Aromatic 200 is a noncombustible/nonflammable petroleum product. Aromatic 200 may be used in either a fertilizer blender or through direct injection systems. Do not use drying agents when using Aromatic 200.

Mixtures of AGH19016 and Aromatic 200 must be used on dry fertilizer only. Poor results or crop injury may result if these mixtures are used in water or liquid fertilizer solutions for spraying applications. When impregnating AGH19016 in a blender before application, a drier mixture can be obtained by substituting a drying agent for Aromatic 200. The use of a drying agent of 6/30 particle size is recommended. Drying agents are not advised for use with On-The-Go impregnation equipment. Restrictions: To avoid potential for explosion,

1. Do not impregnate AGH19016 on ammonium ni trate, potassium nitrate, or sodium nitrate, either alone or in blends with other fertilizers.
2. Do not combine AGH19016 with a single superphosphate (1-20-0) or triple superphosphate (0-46-0).
3. Do not use AGH19016 on straight limestone, since absorption will not be achieved. Fertilizer blends containing limestone can be impregnated.

Application of Impregnated Dry Bulk Granular Fertilizer Apply 200 - 700 lb. of the herbicide/fertilizer mixture per acre. For best results, apply the mixture uniformly to the soil with properly calibrated equipment immediately after blending. Uniform application of the herbicide/fertilizer mixture is essential in order to prevent possible crop injury to subsequent rotational crops. Non-uniform application may also result in unsatisfactory weed control. In areas where conventional tillage is practiced, a shallow incorporation of the mixture into the soil is advised to obtain satisfactory weed control. On fine- or medium-textured soils in areas where soil incorporation is not planned, i.e., reduced-tillage situations or in some conventional till situations, make applications approximately 30 days before planting to allow moisture to move the herbicide/fertilizer mixture into the soil. On coarse-textured soils, make applications approximately 14 days prior to planting.

Precaution: To help avoid rotational crop injury, make applications as early as possible, since AGH19016 impregnated onto dry bulk fertilizers can be expected to last longer in the soil than AGH19016 applied as a spray in water or fluid fertilizer.

Refer to the label of the other product for additional restrictions. 3 Refer to the specific crop use sections for additional crop rotation precautions. 4 Do not rotate rice after any application to a primary crop at greater than 1.0 lb. a.i. per acre of metribuzin per season.

Replanting If replanting is necessary in fields previously treated with AGH19016, the field may be replanted to soybeans or potatoes. Before replanting, refer to the specific crop use sections for precautions and restrictions.

Activation A small amount of rainfall or irrigation is required to activate AGH19016 following application. In areas of low rainfall, follow a preemergence application with light irrigation of ¼ to ½ inch of water. Do not apply heavy irrigation immediately after application. As with many surface-applied herbicides, weed control and crop tolerance may vary with rainfall and/or soil texture.

Weed Resistance Management AGH19016 contains both a Group 15 herbicide (S-metolachlor) and a Group 5 herbicide (Metribuzin). Any weed population may contain plants naturally resistant to Group 15 and/or Group 5 herbicides. The resistant biotypes may dominate the weed population if these herbicides are used repeatedly in the same field. Appropriate resistance-management strategies should be followed. To delay herbicide resistance, take one or more of the following steps: x Rotate the use of this product or other Group 15 and Group 5 herbicides within a growing season sequence or among growing seasons with different herbicide groups that control the same weeds in a field. x Use tank mixtures with herbicides from a different group if such use is permitted; where information on resistance in target weed species is available use the less resistance-prone partner at a rate that will control the target weed(s) equally as well as the more resistance-prone partner. Consult your local extension service or certified crop advisor if you are unsure as to which active ingredient is currently less prone to resistance.

Page 12 of 21

x Adopt an integrated weed-management program for herbicide use that includes scouting and uses historical information related to herbicide use and crop rotation, and that considers tillage (or other mechanical control methods), cultural (e.g., higher crop seeding rates; precision fertilizer application method and timing to favor the crop and not the weeds), biological (weed-competitive crops or varieties) and other management practices. x Fields should be scouted prior to application to identify the weed species present and their growth stage to determine if the intended application will be effective. x Scout fields after herbicide application to monito r weed populations for early signs of resistance development. Indicators of possible herbicide resistance include: o Failure to control a weed species normally controlled by the herbicide at the dose applied, especially if control is achieved on adjacent weeds. o A spreading patch of non-controlled plants of a particular weed species. o Surviving plants mixed with controlled individuals of the same species. If resistance is suspected, prevent weed seed production in the affected area by an alternative herbicide from a different group or by a mechanical method such as hoeing or tillage. Prevent movement of resistant weed seeds to other fields by cleaning harvesting and tillage equipment when moving between fields, and planting clean seed. x If a weed pest population continues to progress after treatment with this product, discontinue use of this product, and switch to another management strategy or herbicide with a different mode of action, if available. x Contact your local extension specialist, certified crop advisors, and/or Winfield Solutions, LLC representative for pesticide resistance management and/or integrated weed management recommendations for specific crops and resistant weed biotypes. x For further information or to report suspected resistance, contact your Winfield Solutions, LLC representative.

CROPS

POTATOES (EXCEPT CALIFORNIA) AGH19016 may be used for preemergence weed control prior to or after potato emergence. AGH19016 has some postemergence activity on weeds, but the co nsistency and spectrum of weed control is much better preemergence to weeds. There is an increased risk of crop injury with preplant incorporated applications. The application rates for AGH19016 for use in potatoes are provided below (Table 3 and Table 4). When a rate range is given, use the lower rate within the range on the more coarse-textured soils listed within that group and/or where weed pressures are known to be light; use the high end of the rate range on the more fine-textured soils listed within that group and/or where the weeds pressures are known to be heavy.

See Table 2 for a listing of weeds controlled/suppressed by AGH19016.

Restrictions:

1. Do not apply more than two treatments per year.
2. For potatoes grown in soils with organic matter between 3% and 10% do not apply more than 5.1 pints (3.35 lbs. a.i. S-metolachlor; 0.80 lb. a.i. metribuzin) per acre/year.
3. For potatoes grown in soils with organic matter between 0.5% and 3.0% do not apply more than 4.95 pints (3.25 lbs. a.i. S-metolachlor; 0.77 lb. a.i. metribuzin) per acre/year.
4. Do not apply AGH19016 to muck or peat soils.
5. Do not apply more than 1.0 lb. a.i. of metribuzin per acre/year from any source.
6. Pre-harvest Interval (PHI): Do not harvest within 60 days of the last AGH19016 application.
7. Do not apply after June 30 in Idaho, Oregon, or Washington if the treated land will be planted to a crop other than potatoes in the fall.

Page 14 of 21

8. Do not apply AGH19016 to sweet potatoes or yams.

Precautions:

1. To avoid crop injury, make postemergence applications only on russetted or white skinned varieties of potatoes that are not early maturing. Avoid postemergence applications on Atlantic, Bellchip, Centennial, Chipbelle, Shepody and Superior varieties. Preemergence applications on these varieties may cause crop injury under adverse weather conditions, on coarse soils, under high soil pH and with higher use rates.
2. Potato varieties may vary in their response to a given herbicide application. When using AGH19016 for the first time on a particular variety, always determine crop tolerance before using on a field-scale.
3. The planting of sensitive crops such as lettuce, cole crops and cucurbits during the next growing season following application of AGH19016 may result in injury to that crop.
4. Certain cereal varieties are sensitive to metribuzin an d are not advised to be planted during the next growing season unless the following cultural practices occur: a) Potato vines left in the row as a result of harvest must be uniformly distributed over the soil surface prior to plowing, and b) Plow with a moldboard plow to a depth sufficient to mix the upper 8 inches of soil.
5. Crop injury may occur if AGH19016 is applied as a preplant incorporated application in potatoes.
6. Applying AGH19016 postemergent when the weather in the next 3 days is predicted to be cool, wet or cloudy, may cause crop injury.

Preemergence Applications Apply with ground spray equipment, aerial spray equipment, or by center pivot irrigation equipment which is capable of making a uniform broadcast application. Apply after planting but before crop emergence, or apply after drag-off if this operation is part of the usual cultural practice.

Tank Mixtures With Other Products Registered for Use in Potatoes For preemergence applications in potatoes, AGH19016 ma y be tank mixed with other pesticide products registered for use in this way and timing in potatoes.

For postemergence applications (center pivot irrigation applications only), i.e. where potato vines are exposed, there may be increased risk of crop injury from certain product mixtures. At this application timing, tank mix AGH19016 only with pesticide products which allow tank mixing and postemergence chemigation on their product label.

See the Tank Mix section on this label for further information on tank mixing.

SOYBEANS (EXCEPT CALIFORNIA) AGH19016 may be applied preplant surface, preplant incorporated, preemergence, as a sequential application, or as a postemergence directed (see state limitations) to control weeds listed on this label. See Table 2 for a listing of weeds controlled/suppressed by AGH19016.

Grazing and Feeding Treated Soybean Plants Do not graze or feed soybean plants to livestock if they have received a post-emergent (directed application) treatment. For other applications, treated soybean plants may be grazed or fed to livestock 40 days after the last application of AGH19016.

Rate Ranges Where a rate range is shown, use the lower rate on soils that are coarse-textured and/or low in organic matter. Use the higher rate on soils that are relatively fine-textured and/or high in organic matter.

Replanting If replanting is necessary in fields previously tr eated with AGH19016, the field may be replanted to soybeans. Minimum tillage is advised. E xcessive tillage will reduce residual weed control. Do not apply a second treatment as injury to soybeans may occur.

Precautions Injury to soybeans or reduced weed control may occur when AGH19016 is used under the following conditions. Avoid these conditions wherever possible.

1. When soils have a calcareous surface area or a pH of 7.5 or higher.
2. Due to the sensitivity of certain soybean varieties, do not apply AGH19016 on varieties that are not confirmed as being tolerant to metribuzin. Consult the seed supplier for information on its tolerance to metribuzin (an active ingredient in AGH19016) before using AGH19016.
3. When applied in conjunction with soil-applied organic phosphate pesticides.
4. Uneven application or improper incorporation of AGH19016 can decrease the level of weed control and/or increase the level of crop injury.
5. When applied to any soil with less than 0.5% organic matter.
6. Where soil incorporation is deeper than recommended.
7. When sprayers were not calibrated accurately.
8. When heavy rains occur soon after application, especially in poorly drained areas where water may stand for several days.
9. When soybeans are planted less than 1½” deep, particularly when AGH19016 is applied preemergence.
10. Where high soil levels of atrazine are present.
11. When using poor quality soybean seed.

Restriction: Do not exceed 3.71 lbs. a.i. per acre per year of S-metolachlor containing products.

Tank Mixing AGH19016 may be tank mixed with other products at appropriate rates as long as tank mixing is not prohibited by the label(s) of the tank mix partner products, or as otherwise noted within the soybean section of this label and the tank mix partner products are labeled for the timing and method of application.

See the Tank Mix section on this label for further information on tank mixing.

AGH19016 Foundation Program for a Planned 2-Pass Weed Control Systems (preplant incorporated or preemergence application followed by other herbicide) AGH19016 may be applied preplant incorporated or preemergence at 1.5 - 1.8 pt./A on all soils to reduce competition from the weeds listed in Table 2 for a 30-day period when followed by a planned postemergence weed control treatment. On soils with pH above 7.0, use the 1.5 pt./A rate only. Recommended postemergence treatments include any product or combination of products labeled to control the specific weeds remaining in the field, including glyphosate products (for use only on glyphosate tolerant soybean varieties). Follow all application directions for AGH19016 used alone, either preplant incorporated or preemergence. For the postemergence herbicide application, consult the selected postemergence herbicide manufacturer’s label for weeds controlled, weed size, application rate, additional use directions, precautions, and limitations before use. See the Tank Mix section on this label for further information on tank mixing.

AGH19016 in Conventional Tillage Systems Preplant Incorporated Application: Incorporate AGH19016 uniformly into the top 2 inches of soil within 14 days before planting using a disk, field cultivator, rolling cultivator, or similar implement. Apply AGH19016 preplant incorporated if furrow irrigation is used or when a period of dry weather after application is expected. If soybeans are planted on beds, apply and incorporate the tank mixture after bed formation. Preemergence Application: Dry weather following preemergence application of AGH19016 may reduce effectiveness. If weeds develop, cultivate uniformly with shallow tilling equipment such as a rotary hoe that will not damage soybeans. For information on applying product in fluid or dry fertilizer, refer to Application in Water or Fluid Fertilizers or Impregnation Onto Dry Bulk Granular Fertilizers and Application of Impregnated Dry Bulk Granular Fertilizer on this label.

For maximum control of sicklepod, use a preemergence application.

Precaution: On soils with pH above 7.0, soybean injury caused by the metribuzin in AGH19016 may occur at rates higher than 1.5 pt./A. To avoid injury, do not use AGH19016 at rates greater than 1.5 pt./A on soils above pH 7.0.

Burndown Weed Control AGH19016 can be used as part of a burndown herbicide program for control of existing vegetation prior to soybean emergence in conservation tillage (reduced- tillage/no-till) systems.

AGH19016 may be tank mixed with other herbicides registered for the same use and timing for control of emerged weeds prior to crop emergence. Apply AGH19016 burndown tank mixes before planting or prior to crop emergence. See the Tank Mix section on this label for further information on tank mixing.

Application AGH19016 may be applied up to 30 days before planting or preemergence. Apply only by ground equipment when AGH19016 is used for burndown of existi ng vegetation in conservation tillage systems. Use the high end of the rate range for AGH19016 applications made 14 - 30 days before planting. Refer to Table 7 for rates of AGH19016. Refer to the tank mix product labels for rates and use directions. Follow all label directions, restrictions, and precautions for tank mix partners. Where differences arise, the more restrictive language must be followed.

Refer to the Product Information section of this label for additional information, precautions, and limitations.

Restrictions for Burndown Weed Control in Soybeans:

1. Do not apply these treatments after crop emergence.
2. Burndown application may only be made by ground.
3. Soybean plants or hay treated with AGH19016 as a burndown treatment may be grazed or fed to livestock 40 days after application. Follow the most restrictive preharvest interval of all products used in a tank mixture.

AGH19016 Use Rates For Reduced and No-Till Systems

Preplant Surface Application AGH19016 may be used in reduced-till and no-till systems. Applications may be made up to 30 days before planting or after planting, but before soybean emergence.

Residual herbicides may be tank mixed for additional weed control. If weeds are present at time of application, burndown herbicides may be added to the tank mixes (see Burndown Weed Control section). Refer to the tank mix product labels for rates and use directions. See the Tank Mix section on this label for further information on tank mixing.

On coarse-textured soils, do not use on loamy sand soils with less than 2% organic matter. 3 Silty clay loam soils are transitional soils and may be classified as medium-textured soils in some regions of the U.S. When using AGH19016, treat this soil as “fine-textured.”

AGH19016 Sequential Application An early preplant (surface-applied or shallow incorporated) application of AGH19016, followed by a preemergence application of AGH19016 after planting but before soybean emergence, will provide more consistent control of broadleaf and grass weeds than a single application.

A sequential application will decrease the need for tillage and/or burndown herbicides for the control of existing vegetation before planting, while providing residual control of weeds after planting.

Application An early preplant application may be made 15 - 30 days before planting soybeans. Follow this application with a preemergence overlay application of AGH19016 after planting but before crop emergence. Follow directions on this label for sequential applications from 0 - 14 days before planting.

Where a rate range is listed, use the higher rates (a) in fields with a history of severe weed pressure, (b) when the time between early preplant and preemergence overlay applications approaches the maximum 30 days, (c) when the organic matter content of the soil is over 3%, and/or (d) when heavy crop residues are present on the soil surface. When weeds exceed 1 - 1.5 inches in height or diameter at application, use a burndown herbicide, such as glyphosate, paraquat, or 2,4-D LVE. Weeds Controlled: In addition to weeds controlled by AGH19016 alone, the sequential application improves control of the following annual broadleaf weeds: buffalobur, cocklebur, common ragweed, velvetleaf, and sunflower.
