GENERAL INFORMATION WECO MAXTM is formulated as an emulsifiable concentrate of octanoic acid and heptanoic acid esters of bromoxynil containing the equivalent of 2.0 pounds of bromoxynil per gallon and 2.5 pounds per gallon of 2-ethylhexyl ester of 2,4-D. WECO MAXTM is a postemergence herbicide for control of important broadleafweeds infesting wheat, barley, oats and rye. Optimum weed control is obtained when WECO MAXTM is applied to actively growing weed seedlings. WECO MAXTM is primarily a contact herbicide, therefore thorough coverage of the weed seedlings is essential for optimum control. WECO MAXTM has little residual activity. Therefore subsequent flushes of weeds will not be controlled by the initial treatment. Generally crops that form a good canopy will help shade subsequent weed flushes. Occasional transitory leaf burn may occur. The temporary leaf burn is similar to that seen with liquid fertilizer. Because the activity of WECO MAXTM is mainly contact, recovery of the crop is generally rapid with no lasting effect. Frequency and amount of leaf burn may be greater when crops are stressed by abrasive winds, cool to cold evening temperatures or mechanical injury, such as that caused by hail, sleet or insect feeding. To reduce the potential for temporary leaf burn, applications should be made to dry foliage in the recommended spray volumes per acre when weather conditions are not extreme. MIXING, LOADING AND HANDLING INSTRUCTIONS 2.5 Gallon Containers It is strongly recommended that special care be taken in mixing and loading this product. Hands should be placed on the container in such a way as to avoid possible drip or splash. Correct procedures for mixing and loading are provided in Bayer CropScience's Educational Program. Bulk Containers c , If you will handle a total of 48 gallons or more of this product per day, you must use a mechanical trcnf8r'€ystemr~;11 ixing and loading operations. If this product is packaged in a 30 gallon or larger container, you must use a mochaniQi:l1 transfer '<;ystem which terminates in a drip-free hard coupling which may be used only with a spray or mix tank which ha'>ot;'!tJl fitted ; 6.' compatible coupling. If you do not presently own or have access to a mechanical transfer system with this type of cO[Jplit1., contact yauer dealer for information on how to obtain such a system or to modify your present system. When using a mechan;cral transf3c; <system, do not remove or disconnect the pump or probe from the container until the container has been emptied 2.'Ilj.';r:;sed. The pu..,p or probe system must be used to rinse the empty container and to transfer the rinsate directly to the mixing or spra)tat. (. l.O)CO WECO MAX'" HERBICIDE ALONE: Fill the spray tank 1/2 to 3/4 full with clean water. Begin agitation and add the recomT!endod amount of WECO MAX ™ brand Herbicide. Add water to the spray tank to the desired level. Maintain sufficient agitation to ensl!:re" ae ~~iform spray mixture during application. c (, () C C Q TANK MIXTURES: WECO MAXTM may be tank-mixed with other pesticide products provided that these other products 'doG ~'egistered for use on the crop/use site to be treated. The tank mix must be used in accordance with the more restrictive pesticide label limitations and precautions. No label dosage rates may be exceeded. WECO MAXTM cannot be mixed with any product containing a label prohibition against such mixing. . WECO MAXTM can be applied in tank mixture with many other herbicides and insecticides registered for use on approved crops. Refer to the specific crop section for rate recommendations and other restrictions. To apply WECO MAXTM in mixture with another product, fill the spray tank 1/2 to 3/4 full with clean water and begin agitation. If tankmixing with wettable powder, soluble powder, flowable or dry flowable products, add the powder or flowable product first. After the other herbicide is thoroughly mixed with water add the recommended amount of WECO MAXTM and add water to the spray tank to the desired level. If tankmixing with other product types, add the WECO MAX ™ first before adding the other product. Always mix one product in water thoroughly before adding another product or compatibility problems may occur. Maintain sufficient agitation while mixing and during application to ensure a uniform spray mixture. If spray mixture is allowed to remain without agitation for short periods of time, be sure to agitate until uniformly mixed before application. If tank mixing with products other than those listed within each crop section, a compatibility test is recommended to ensure satisfactory spray preparation. To test for compatibility, use a small container and mix a small amount (0.5 to 1 quart) of spray, combining all Page 4 of 12

c 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 incompatibility usually will appear within 5 to 15 minutes after mixing. To ensure maximum crop safety and weed control, follow all cautions and limitations on this label and the labels of products used in the tank mixture with WECO MAXTM. SPRAVABLE LIQUID FERTILIZERS AND SPRAY ADDITIVES WECO MAXTM can be applied in combination with sprayable liquid fertilizer or spray additives such as surfactants or crop oil concentrate. When tankmixing with liquid fertilizer always add the fertilizer to the spray tank first and agitate thoroughly before adding WECO MAXTM. Always predetermine the compatibility with liquid fertilizer by mixing small proportional quantities in advance. Agitation must be maintained during filling and application operations to ensure that WECO MAXTM is evenly mixed with the fertilizer. Leaf burn may occur when WECO MAXTM is applied with liquid fertilizer, but new leaves are not adversely affected. NOTICE: Fertilizers and spray additives can increase foliage leaf burn when applied with WECO MAXTM. Do not apply fertilizers or spray additives with WECO MAXTM if leaf burn is a major concern due to environmental conditions, crop or variety sensitivity to WECO MAXTM. If WECO MAXTM is mixed with liquid fertilizer, the fertilizer should compose no more than 1/2 the total spray mix. APPLICATION PROCEDURES WECO MAXTM can be applied to registered use areas by ground, aerial and sprinkler irrigation equipment. EQUIPMENT All aerial and ground application equipment must be properly maintained and calibrated using appropriate carriers or surrogates. 2,4-0 esters may volatilize during conditions of low humidity and high temperatures. Do not apply during conditions of low humidity and temperatures. GROUND APPLICATION Select a spray volume and delivery system that will ensure thorough and uniform spray coverage. For optimum spray distribution and thorough coverage use of flat fan nozzles spaced no more than 20 inches on the boom with a spray pressure of 40-50 psi are recommended. Nozzle types, nozzle spacings and lower spray pressures that product coarse spray droplets may not provide adequate coverage of the weeds to ensure optimum control. Raindrop® nozzles and flood nozzles are not recommended as weed control with WECO MAXTM may be reduced. A spray volume of 10 to 20 gallons per acre (GPA) is recommended for optimum spray coverage. A maximum ground speed of 10 mph is suggested. Ground applications made when dry, dusty field conditions exist may provide reduced weed control in wheel track areas. Applications using less than 10 gallons per acre may result in reduced weed control. When weed infestations are heavy, use of higher spray volumes will be helpful in obtaining uniform weed coverage. If you are unsure of the infestation level or size of crop, consult your local agronomist or extension service. Do not apply with a nozzle height greater than 4 feet above the crop canopy. Do not apply when winds are gusty or when other conditions favor poor spray coverage andlor off target spray movement. AERIAL APPLICATION Use orifice discs, cores and nozzle types and arrangements that will provide for optimum spray distribution and maximum coverage. A minimum spray volume of 5 GPA and a maximum pressure of 40 psi are recommended. A minimum spray volume of 3 gallons per acre may be used if crop canopy and weed density allow adequate spray coverage. Aerial applications using less than 5 gallons of spray volume per acre may result in reduced weed control. c c c ( ( ,- f l l ( ~ l Do not apply during inversion conditions, when winds are gusty or when other conditions favor poor 8pra& verage andlor off target spray movement.

c SPRAY DRIFT MANAGEMENT A variety of factors including weather conditions (e.g., wind direction, wind speed, temperature, relative humidity) and method of application (e.g., ground, aerial, airblast, chemigation) can influence pesticide drift. The applicator must evaluate all factors and make appropriate adjustments when applying this product. 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 habitats for threatened or endangered species, non-target crops) is minimal (e.g., when wind is blowing away from the sensitive areas). Avoiding spray drift at the application site is the responsibility of the applicator. The interaction of many equipment-and-weather-related factors determine the potential for spray drift. The applicator and the grower are responsible for considering all these factors when making decisions. . The following drift management requirements must be followed to avoid Off-target drift movement from aerial applications to agricultural field crops. These requirements do not apply to forestry applications, public health uses or to applications using dry formulation.

1. The distance of the outer most nozzles on the boom must not exceed 3/4 the length of the wingspan or rotor.
2. Nozzles must always point backward parallel with the air stream and never be pOinted downwards more than 45 degrees. DROPLET SIZE: When applying sprays that contain 2,4-D as the sole active ingredient, or when applying sprays that contain 2,4-0 mixed with active ingredients that require a Coarse or coarser spray, apply only as a Coarse or coarser spray (ASAE standard 572) or a volume mean diameter of 385 microns or greater for spinning atomizer nozzles. When applying sprays that contain 2,4-0 mixed with other active ingredients that require a Medium or more fine spray, apply only as a Medium or coarser spray (ASAE standard 572) or a volume mean diameter of 300 microns or greater for spinning atomizer nozzles. CONTROlliNG DROPLET SIZE: (This section is advisory in nature and does not supersede the mandatory label requirements) • Volume - Use high flow rate nozzles to apply the highest practical spray volume. Nozzles with higher rated flows produce larger droplets. • Pressure - Do not exceed the nozzle manufacturer's recommended pressures. For many nozzle types lower pressure produces larger droplets. When higher flow rates are needed, use higher flow rate nozzles instead of increasing pressure. • Number of nozzles - Use the minimum number of nozzles that provide uniform coverage. • 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. • Nozzle Type - Use a nozzle type that is deSigned for the intended application. With most nozzle types, narrower spray angles produce larger droplets. Consider using low-drift nozzles. Solid stream nozzles oriented straight back produce the largest droplets and the lowest drift. BOOM LENGTH: The boom length must not exceed 75% of the wingspan or 90% of the rotor blade diameter. For some use patterns, reducing the effective boom length to less than 3/4 of the wingspan or rotor length may further reduce drift without reducing swath width. APPLICATION HEIGHT: Release spray at the lowest height consistent with efficacy and flight safety. Do not release spray at a height greater than 10 feet above the crop canopy 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. SWATH ADJUSTMENT: When applications are made with a crosswind, the swath will be displaced downwind. 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.) WIND SPEED: 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. NOTE: Local terrain can influence wind patterns. Every applicator should be familiar with local wind patterns and how they affect spray drift. Do not apply at wind speeds greater than 15 mph. Only apply this product if the wind direction favors on-target deposition and there are not sensitive areas (including, but not limited to, residential areas, bodies of water, known habitat for nontarget species, nontarget crops) within 250 feet downwind. If applying a Medium spray, leave one swath unsprayed at the downwind edge of the treated field. TEMPERATURE AND HUMIDITY: When making applications in low relative humidity, set up equipment to produce larger droplets to compensate for evaporation. Droplet evaporation is most severe when conditions are both hot and dry. Page 6 of 12 7 -l)

TEMPERATURE INVERSIONS: Applications should not occur during a temperature inversion because drift potential is high. Temperature inversions restrict vertical air mixing, which causes small suspended droplets to remain in a concentrated cloud. This cloud can move in unpredictable directions due to the light variable winds common during inversions. Temperature inversions are characterized by increasing temperatures with altitude and are common on nights with limited cloud cover and light to no wind. They begin to form as the sun sets and often continue into the morning. Their presence can be indicated by ground fog; however, if fog is not present, inversions can also be identified 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. If applying at wind speeds less than 3 mph, the applicator must determine if: a) conditions of temperature inversion exist, or b) stable atmospheric conditions exist at or below nozzle height. Do not make applications into areas of temperature inversions or stable atmospheric conditions. SUSCEPTIBLE PLANTS Do not apply under circumstances where spray drift may occur to food, forage, or other plantings that might be damaged or crops thereof rendered unfit for sale, use or consumption. Susceptible crops include, but are not limited to, cotton, okra, flowers, grapes (in growing stage), fruit trees (foliage), soybeans (vegetative stage), ornamentals, sunflowers, tomatoes, beans, and other vegetables, or tobacco. Small amounts of spray drift that might not be visible may injure susceptible broadleaf plants. Other State and Local Requirements Applicators must follow all state and local pesticide drift requirements regarding application of 2,4-D herbicides. Where states have more stringent regulations, they must be observed. SPRINKLER IRRIGATION APPLICATION WECO MAXTM brand Herbicide can be applied through sprinkler irrigation systems to wheat, barley, oats and rye. Apply WECO MAXTM brand Herbicide through sprinkler systems including center pivot, lateral move, side (wheel) roll, solid set or hand move irrigation systems only. If hand moved pipe is used for chemigation, the pipe must not be handled in any way until 24 hours after chemigation has been completed and residues have been flushed from the system. When applying by chemigation, no person may enter the application site unless in an enclosed vehicle. Do not apply this product through any other type of irrigation system. SPECIFIC REQUIREMENTS FOR APPLICATION THROUGH AUTOMATED SPRINKLER IRRIGATION SYSTEM

1. 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.
2. The pesticide injection pipeline must contain a functional, automatic, quick-closing check valve to prevent the flow of fluid back toward the injection pump.
3. 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.
4. The system must contain functional interlocking controls to automatically shut off the pesticide injection pump when the water pump motor stops.
5. 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.
6. Systems must use a metering pump, such as a positive displacement injection pump (e.g., diaphragm pump) effectively designed and constructed of materials that are compatible with pesticides and capable of being fitted with a system interlock.
7. Do not apply when wind speed favors drift beyond the area intended for treatment.
8. Agitation is recommended in the pesticide supply tank when applying the WECO MAX TM.
9. WECO MAXTM brand Herbicide should be applied continuously for the duration of the water application with center pivot and continuous lateral move systems. Application of WECO MAXTM brand Herbicide should be made during the last 30-45 minutes of the irrigation set with other overhead sprinkler systems.
10. For best performance, set the sprinkler system to deliver approximately 0.5 inch or less of water per acre.
11. Remove scale, pesticide residues and other foreign matter from the supply tank and entire injector system. Flush with clean water.
12. If WECO MAXTM brand Herbicide is diluted in the supply tank, fill the tank with half of the water amount desired, add the WECO MAXTM and then add remaining water amount with agitation. Always dilute with at least 4 parts water to 1 part WECO MAXTM.
13. Start the sprinklers and then inject WECO MAXTM brand Herbicide into the irrigation fine. WECO MAXTM should be injected with a positive displacement pump into the main line at least 8 feet ahead of a right angle turn to insure adequate mixing. Refer to the WECO MAXTM brand Herbicide label for detailed information on application rates and timings. Page 7 of 12 ~ -I~

c CHEMIGATION USE RESTRICTIONS AND PRECAUTIONS Application of more than 0.5 inch/acre of irrigation water may result in decreased product performance on certain soils. Do not apply when conditions favor drift, when system connections or fittings leak, or when nozzles do not provide uniform distribution. Allow sufficient time for pesticide to be flushed through all the lines and nozzles before turning off irrigation water. Crop injury, lack of effectiveness, or illegal pesticide residues in the crop can result from non-uniform distribution of treated water. Do not connect an irrigation system used for pesticide application to a public water system. If you have questions about calibration, you should contact State Extension Service specialists, equipment manufacturers or other experts. A person knowledgeable of the chemigation system and responsible for its operations, or under the supervision of the responsible person, shall shut the system down and make necessary adjustments should the need arise.
