USE INFORMATION WG 63 Herbicide is a selective herbicide for control of important broadleaf and grassy weeds infesting field corn, sweet corn and popcorn. WG 63 Herbicide can be used in corn grown for silage, grain or seed. WG 63 Herbicide can be applied for post harvest or postemergence uses. WG 63 Herbicide is effective in controlling triazine resistant populations of weed species which are listed in the “BROADLEAF AND GRASS WEEDS CONTROLLED BY WG 63 HERBICIDE” tables below on this label. Corn hybrids and certain male pollinators within blended corn varieties vary in their response to WG 63 Herbicide. Not all hybrids or male pollinators within blended corn varieties have been tested for sensitivity to WG 63 Herbicide. You should consult with your seed provider, your local Bayer CropScience representative and/or other knowledgeable agricultural professionals for advice on tolerance of hybrids or varieties containing male pollinator lines before applying WG 63 Herbicide. If the tolerance of a hybrid or variety containing male pollinator lines is not known, you should apply WG 63 Herbicide to a small area to first determine if the hybrid is tolerant prior to spraying large acreages of that hybrid. WG 63 Herbicide also contains a safener, which greatly reduces or prevents the temporary yellowing or stunting crop response associated with the contained this herbicide chemistry. If symptoms appear, corn quickly outgrows the effect and develops normally. WEED RESISTANCE MANAGEMENT For resistance management, WG 63 Herbicide is a Group 2 herbicide. Any weed population may contain or develop plants naturally resistant to WG 63 Herbicide and other Group 2 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: • Rotate the use of WG 63 Herbicide or other Group 2 herbicides within a growing season sequence or among growing seasons with different herbicide groups that control the same weeds in a field. • 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. 5 • 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. • Scout after herbicide application to monitor weed populations for early signs of resistance development. Indicators of possib le herbicide resistance include: (1) failure to control a weed species normally controlled by the herbicide at the dose applied, especially if control is achieved on adjacent weeds; (2) a spreading patch of non-controlled plants of a particular weed species; (3) 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. • If a weed pest population continues to progress after treatment with this product, discontinue use of this product, and switc h to another management strategy or herbicide with a different mode of action, if available. • Contact your local extension specialist or certified crop adv isors for additional pesticide resistance-management and/or integrated weed-management recommendations for specific crops and weed biotypes. • For further information or to report suspected resistance contact Bayer CropScience at 1-866-99BAYER (1-866-992-2937). You ca n also contact your pesticide distributor or university extension specialist to report resistance. MANDATORY SPRAY DRIFT Aerial Applications: • 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. • Applicators are required to use a medium or coarser droplet si ze in accordance with the most current version of the American Society of Agricultural & Biological Engineers Standard 641 (ASABE S641) for all applications. • 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. • 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. • Do not apply during temperature inversions. Ground Boom Applications: • User must only apply with the release height recommended by the manufacturer, but no more than 4 feet above the ground o r crop canopy. • Applicators are required to use a medium or coarser droplet size in accordance with the most current version of the America n Society of Agricultural & Biological Engineers Standard 572 (ASAE S572). x Do not apply when wind speeds exceed 15 miles per hour at the application site. x Do not apply during temperature inversions.

BE AWARE OF NEARBY NON-TARGET SITES $1'(19,5210(17$/&21',7,216 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 9ROXPH- 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. BOOM HEIGHT – Ground Boom For ground equipment, the boom should remain level with the crop and have minimal bounce. 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. 6 RELEASE HEIGHT - Aircraft Higher release heights increase the potential for spray drift.

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.

To obtain optimum weed control with an application of WG 63 Herbicide follow label directions and use when weeds are actively growing. x Weed control may be reduced if the application is made when weeds are dust covered or in the presence of heavy dew, fog, and mist/rain or when weeds are under stress due to drought. x Tank contamination can cause severe damage to other crops. Careful management of tank clean out is required. See Tank Cleanout section for complete instructions. x DO NOT graze livestock, or harvest corn forage or sweet corn ears within 45 days of application of WG 63 Herbicide. INSECTICIDE INTERACTION INFORMATION Soil applied insecticide interaction information When WG 63 Herbicide and certain organophosphate (OP) or carbamate insecticides are applied to corn, injury can result. DO NOT USE WG 63 Herbicide in the same season as Lorsban®, Counter® 15G, Counter® 20G, Dyfonate®, or Thimet®. For all corn hybrids, the following table describes the uses of soil-applied insecticides prior to an application of WG 63 Herbicide: Soil Applied Insecticide Use Pattern Use of WG 63 Herbicide in the Same Season Aztec®, Regent®Tefluthrin (e.g. Force®) All No use precautions Chlorpyrifos (e.g.Lorsban® 15G), Terbufos (e.g. Counter® 15G, Counter® 20CR), Phorate (e.g Thimet®), Fonophos (e.g Dyfonate) All Do Not Use Foliar Insecticide Interaction Information Foliar applications of an organophosphate or carbamate insecticide should not be made within 7 days of an application of WG 63 Herbicide or crop injury may result. 7 ROTATIONAL CROP RESTRICTIONS Rotational crops vary in their crop response to low concentrations of WG 63 Herbicide remaining in the soil. The amount of WG 6 3 Herbicide that may be present in the soil depends on soil moisture, soil temp, application rate, elapsed time since application and other environmental factors. When WG 63 Herbicide is used in combination with other products, always follow the most restrictive rota tional crop requirements. The active ingredient, thiencarbazone-methyl is used in multiple products. When determining rotational crop intervals the total application rate of thiencarbazone-methyl from all sources should be included on an equivalent basis to WG 63 Herbicide rates when determining crop rotation intervals from Tables 1 and 2. The following rotational crops may be planted after applying WG 63 Herbicide in corn: Table 1. Minimum recropping intervals for various crops following WG 63 Herbicide application at rates totaling greater than 1.0 ounce of product per acre. Rotational Interval (elapsed time) Crop Minimum precipitation requirement 1 0 Months 2 Yellow field corn None 3 Months2 Wheat None 9 Months2 Barley, Cotton, Soybean, Sweet corn 3, Popcorn3, White field corn3 15 inches of cumulative precipitation from application to planting of rotational crop 17 Months3 Alfalfa, Green and Dry Beans, Sorghum, Oats, Sunflower, Canola, Potato, Sugar beet and All other crops 30 inches of cumulative precipitation from application to planting of rotational crop 1The amount of cumulative precipitation required before planting a rotational crop is in addition to the required rotational interval given in months.

MIXING INSTRUCTIONS Application with water carrier or liquid fertilizer (prior to crop emergence ONLY) carrier: Fill the spray tank 1/4 to 1/2 of the required volume of water or liquid fertilizer prior to the addition of WG 63 Herbicide, and begin agitation. Slowly add the proper amoun t of WG 63 Herbicide, and begin bringing the water or liquid fertilizer to the desired level. Maintain sufficient agitation to ensure a un iform spray mixture during application. If WG 63 Herbicide is applied in a tank mixture with other pesticides, add WG 63 Herbicide to the s pray tank first and ensure it is thoroughly dispersed before adding other pesticides. If ammonium sulfate (AMS) is the nitrogen fertilizer source, it is preferred that the AMS go into the tank after the WG 63 Herbicide and before other pesticide tank mix partners. If UAN is the n itrogen fertilizer source, it should be added to the tank after other pesticide tank mix partners. Add surfactants to the tank last. Continue to fill the tank with carrier to the desired volume while agitating. CONTINUE AGITATION DURING APPL ICATION TO ENSURE A UNIFORM SPRAY MIXTURE. Re-suspending WG Products in Spray Solution: Like other water dispersible granules (WG’s), WG 63 Herbicide will settle if left standing without agitation. If the spray solution is allowed to settle for one hour or more, reagitate the spray solution for a minimum of 10 minutes before application. 8 TANK CLEANUP PROCEDURE Cleaning Equipment After WG 63 Herbicide Application Special attention must be given to cleaning equipment before spraying a crop other than corn. Mix only as much cleaning solution as needed. 1. Flush tank, hoses, boom and nozzles with clean water. 2. Use a pressure washer with a high quality commercial spray tank cleaner in water to clean the inside of the spray tank. Take care to wash all parts of the tank, including the inside top surface. If a pressure washer is not available, 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 recirculate the cleaning solution for at least 15 minutes. All visible deposits must be removed from the spraying system. 3. Flush hoses, spray lines, and nozzles for at least 1 minute with the cleaning solution. 4. Dispose of rinsate from steps 1-3 in an appropriate manner. 5. Repeat steps 2-4. 6. Remove nozzles, screens and strainers and clean separately in the cleaning solution after completing the above procedures. 7. Rinse the complete spraying system with clean water. 8. Cleanup should be conducted on an approved rinse pad or the field site where an approved crop is to be grown. TANK MIXTURES WG 63 Herbicide can be applied in tank mixture with many other pesticides registered for use on approved crops. Refer to “Tank Mix Combination” section for rates and other restrictions. COMPATIBILITY If WG 63 Herbicide is to be tank mixed with liquid fertilizers or other pesticides, compatibility should be tested prior to mix ing. To test for compatibility, use a small container and mix a small amount (0.5 to 1 qt) of spray, combining all ingredients in the same ratio as the anticipated use. If any indications of physical incompatibility develop, do not use this mixture for spraying. Indications of i ncompatibility usually will appear within 5-15 minutes after mixing. Read and follow all parts of the label of each tank-mix product. APPLICATION PROCEDURES APPLICATION TIMING WG 63 Herbicide may be: x Used in either conventional, conservation tillage, or no-till crop management systems. x Applied postemergence to corn. x Used during the non-cropped period from harvest of preceding crop to 30 days prior to planting of next crop. Postemergence: Broadcast: WG 63 Herbicide alone and/or in certain tank mixtures may be applied broadcast to corn from spiking through the 6th leaf collar growth stage (9the first leaf has a rounded tip) at rates as defined under the Specific Use Directions section of this label.

Use drop nozzles and appropriate spacing to direct spray below the corn whorl and upper leaves. The top of the target weed canopy must be sufficiently below the whorl and upper leaves of the crop to permit this application and provide adequate spray coverage. The height differential required between the crop and weed canopy will depend on the specific equipment used. DO NOT graze livestock, or harvest corn forage or sweet corn ears within 45 days of application of WG 63 Herbicide. Post-Harvest: WG 63 Herbicide may be used alone or in combination with other registered herbicides as a fall to early spring-applied ground broadcast application for burn down and residual control of certain winter annual broadleaf and other weeds listed on this label. Apply WG 63 Herbicide to unfrozen ground from harvest of preceding crop to 30 days prior to planting of next crop. Applications of WG 63 Herbicide should start at the beginning of emergence of any of the winter annual broadleaf weeds listed on this label. This application will reduce weed cover before spring planting. A fall application of WG 63 Herbicide is not intended to provide weed control throughout the succeeding cropping period, but is part of a weed management program to remove weed covers that rob residual moisture and nutrients from the soil, slow soil warming, and hamper field preparation for and planting of succeeding crops. Weed control in succeeding crops will require additional applications of residual and/or postemergence herbicides for season-long control. Apply 1.0 to 2.5 oz of WG 63 Herbicide plus adjuvants (see spray additives section on this label) for burndown of labeled weeds 6” or less in height. Weed growth ceases within hours after WG 63 Herbicide is applied. Weed death generally occurs within 7 to 14 days after application but is progressively slower as weeds approach the 6-inch height. For post-harvest applications, methylated seed oil 9 (MSO) can be substituted for crop oil concentrate (COC) as an adjuvant. For optimum control, weeds must be in vegetative stages of growth. The length of residual control will increase with the application rate of WG 63 Herbicide. If emerged weeds are present and are greater than 6 inches in height or diameter, use 2,4-D or an appropriate alternative postemergence herbicide in the tank mixture. Control of established common dandelion requires a tank mixture containing at least 1 pint/acre (4-pound/gallon) of 2,4-D, and/or a tank-mixture with AUTUMN™ Herbicide. Field corn, soybean and other crops can only be planted at the intervals specified in the “Rotational Crop Restrictions” section of this label after a post-harvest application of WG 63 Herbicide. Read and follow the entire label for the most restrictive directions of the respective tank mix partner. SPRAY ADDITIVES WG 63 Herbicide is a water dispersible granule that requires the use of an external adjuvant and a nitrogen fertilizer source to achieve optimum weed control. Crop Oil Concentrate Use Crop Oil concentrate (COC) at 1 gallon per 100 gallons of water (1% v/v), with a minimum of 1.25 pt/A. COC should contain at least 80% crop oil and 10% emulsifier or greater. The use of adjuvants such as non-ionic surfactants or refined vegetable oils will result in unacceptable or erratic weed control. Ammonium Nitrogen Fertilizer Use 1.5 qt/A of a high-quality urea ammonium nitrate (UAN), or 1.5 lb/A minimum (or 8.5 lb per 100 gallons) of a spray-grade ammonium sulfate (AMS). Use UAN under conditions of low relative humidity for greater weed control. For tank mixtures with Ignite® 280 SL Herbicide WG 63 Herbicide can be tank mixed with Ignite® 280 SL Herbicide. Ignite® 280 SL Herbicide can only be used on corn seed designated as LibertyLink®. Do not use MSO/ESO or COC adjuvants in this mixture, only add AMS at 8.5 lbs/100 gallons (1.5 lb/A minimum). Follow all other directions for adjuvants as listed on the Ignite® 280 SL label. Follow the most restrictive directions for use and precautions as defined on both herbicide labels. For tank mixtures with Glyphosate (including Roundup® and Touchdown® branded products) WG 63 Herbicide can be tank mixed with glyphosate for use on glyphosate-tolerant corn. WG 63 Herbicide will enhance broadleaf control, combat glyphosate-resistant weeds and reduce glyphosate induced weed shifts. Do not use MSO/ESO or COC adjuvants in this mixture. Add AMS at 8.5 lbs/100 gallons (1.5 lb/A minimum) and any additional surfactant as recommended on the Glyphosate label. Follow the most restrictive directions for use and precautions as defined on both herbicide labels.

Apply WG 63 Herbicide alone or in tank mixtures by ground equipment in a minimum of 10 gallons of spray mixture per acre. Unifo rm, thorough spray coverage is important to achieve consistent weed co ntrol. Use sprayers that provide accurate and uniform applica tion. For emerged weed control in dense weed populations or under adverse growing conditions, 15 to 20 gallons of water per acre is recommended. Good coverage is essential to achieve optimum control of emerged weeds. To minimize spray drift to non-target areas, apply this product using nozzles which deliver a medium to coarser spray droplet as defined by ASAE standard S-572 and as shown in nozzle manufacturer’s catalogues. Keep the spray boom at the lowest possible spray height above the target surface. Refer to nozzle manufacturer’s recommendations for proper nozzle, pressure setting and sprayer speed for optimum product performance and minimal spray drift. Apply with nozzle height no more than 4 feet above the ground or crop canopy. Over applications, uneven application, sprayers not properly cali brated, boom overlapping or improper incorporation may decreas e the level of weed control and/or increase the level of adverse crop response. Maintain constant ground speed while applying product to ensure proper distribution. MAINTAIN ADEQUATE AGITATION AT ALL TIMES, INCLUDING MOMENTARY STOPS. 10 AERIAL APPLICATION Calibrate the spray equipment prior to use. Apply WG 63 Herbicide in a minimum of 5 gallons of water per broadcast acre. The use of nozzles and spray pressure that deliver MEDIUM spray droplets as indicated in the nozzle manufacturer’s catalogs and in accordance with ASAE Standard S-572 are highly recommended for optimum spray coverage and canopy penetration. DO NOT use raindrop nozzles. Aerial applications of this product should be made at a maximum height of 10 feet above the top of the largest plants unless a greater height is required for aircraft safety. Making applications at the lowest height that is safe reduces exposure of droplets to evaporation and wind. Aerial applications of this product should also be made with low drift nozzles at a maximum pressure of 40 psi. Uniform, thorough spray coverage is important to achieve consistent weed control. See the Spray Drift Management section of this label for additional information on proper application of WG 63 Herbicide. SPECIFIC DIRECTIONS FOR USE IN CORN Postemergence Rates x Apply WG 63 Herbicide to emerged weeds at 1.0 oz of product per acre per application. Always add appropriate adjuvants to the spray tank (see Spray Additives Section of this label). x Applications of WG 63 Herbicide at rates less than 1.0 oz of product per acre postemergence may result in incomplete weed control and reduction in residual activity. x Broadcast applications of WG 63 Herbicide may be made to corn from spiking through the 6- OHDIFROODUVWDJHRIJURZWK 9, the first leaf has a rounded tip)'RQRWDSSO\EURDGFDVWWRFRUQWKDWLVPRUHPDWXUHWKDQWKH9VWDJHRIJURZWK x Directed postemergence applications of WG 63 Herbicide can be made to corn from the 6-leaf collar stage through the 12-leaf FROODUVWDJH 9 RIJURZWK'RQRWDSSO\WRFRUQWKDWLVPRUHPDWXUHWKDQWKH9VWDJHRIJURZWK x Follow all precautions and warnings for using ALS-inhibiting or Sulfonyl urea (SU) herbicides on a particular hybrid/inbred. x Best results with WG 63 Herbicide used postemergence are obtained when it is applied to young actively growing weeds.
