Mode of Action Dyvel™ WG herbicide is a benzoic auxin agonist herbicide belonging to mode of action Group 4 (WSSA) and Group O (HRAC). Dyvel WG is readily absorbed by roots and foliage, translocates throughout the plant, and accu- mulates in areas of active growth, Dyvel WG interferes with the plant growth resulting in control of susceptible broadleaf weeds. Resistance Management While weed resistance to auxin agonist herbicides is rela- tively infrequent, populations of resistant biotypes are known to exist. Resistance management practices include:

1. Follow labeled application rate and weed growth stage recommendations.
2. Avoid repeat application of herbicides with the same mode of action.
3. Use tank mixes and sequential applications with other effective herbicides possessing different modes of action.
4. Rotate crops so crop competition, tillage, or herbicides with alternative modes of action can be used to control weed escapes. Wheat Tolerance Wheat is tolerant to Dyvel WG when applied according to label directions under normal environmental conditions. Crop injury may occur under stressful growing conditions (e.g. seedling disease, extreme hot or cold weather, exces- sive moisture, high soil pH, high soil salt concentration, or drought). Dyvel WG application during periods of rapid wheat growth may result in crop leaning; this condition is temporary and will not reduce crop yield. Application Instructions Dyvel WG can be applied to actively growing weeds as aerial, broadcast, or spot spray applications using water or sprayable fertilizer as a carrier. Application Rates Application rates are 4.2 ozs/A for fallow application and 2.1 to 4.2 ozs/A for wheat postemergence application. Refer to the Crop-specific Information section for crop- specific application timing and other details. Application Methods and Equipment Dyvel WG may be applied by air or ground. Thorough spray coverage is important for broadleaf weed control and can be improved with proper adjuvant, nozzle and spray volume selection. Use and configure application equipment to provide an adequate spray volume, an accurate and uniform distribu- tion of spray droplets over the treated area, and to avoid, spray drift to nontarget areas. Adjust equipment to main- tain continuous agitation during spraying with good mechanical or bypass agitation. Avoid overlaps that will increase rates above the maximum use rates specified in this label. To avoid uneven spray coverage, DO NOT apply Dyvel WG during periods of gusty wind or when wind is in excess of 15 mph. DO NOT cultivate within 7 days after applying Dyvel WG. Aerial Application Requirements Water Volume Use 2 to 10 gallons of water per acre. Use the higher spray volume when treating dense or tall vegetation. The following spray drift management requirements must be followed by aerial applicators to reduce the potential for spray drift:
5. The distance of the outermost nozzles on the boom . must not exceed 3/4 the length of the fixed wingspan or 90% of rotor blade diameter. 2-. Nozzles must always point backward parallel with the ^•airstream and never be pointed downward more than ""45 degrees.
6. Without compromising aircraft safety; release spray at a ..height of 10 feet or less above the crop canopy or tallest -plants. Aerial Application Equipment Select nozzles designed to produce a minimal amount of fee spray particles. Aerially apply at the lowest.safe height to reduce exposing spray to evaporation and wind. The applicator must follow the most restrictive use cautions to avoid drift hazards, including those found in this labeling, as well as state and local regulations and ordinances. DO NOT use aerial equipment if spray particles can be carried by wind into areas where sensitive plants are grow- ing or when temperature inversions exist. Ground Application Requirements Water Volume Use 3 to 50 gallons of spray solution per broadcast acre for optimal performance. Use the higher spray volume when treating dense or tall vegetation. Ground Application Equipment Select nozzles designed to produce a minimal amount of fine spray particles. Spray with nozzles as close to the weeds as practical for thorough weed coverage. Cleaning Spray Equipment Following application, clean application equipment thoroughly using a strong detergent or commercial sprayer cleaner according to the manufacturer's directions, fol- lowed by triple rinsing with clean water.

cSpray Drift Management It is the responsibility of the applicator to avoid spray drift onto nontarget areas. The interaction of many equipment- related and weather-related factors determines the potential for spray drift. The applicator and the grower are responsible for considering all these factors when making decisions. Applicators must follow the most restrictive use precau- tions to avoid drift hazards, including those found in this labeling as well as applicable state and local regulations and ordinances. Sensitive Crop Precautions Avoid off-target movement. Use extreme care when apply- ing Dyvel™ WG herbicide to prevent injury to desirable plants. . . . .... Dyvel WG may cause injury to desirable broadleaf plants including beans, cotton, fruit trees, grapes, ornamentals, peas, potatoes, soybeans, sunflowers, tobacco, and toma- toes. These plants are most sensitive to Dyvel WG during periods of rapid growth or flowering. The applicator must be familiar with and take into account the information covered in the following spray drift reduc- tion advisory information. Information on Droplet Size The most effective way to reduce drift potential is to apply the largest droplets that provide sufficient coverage and control. Use coarse sprays (volume median diameter of 400 microns or more) to avoid potential herbicide drift. Select nozzles designed to produce a minimal amount of fine spray particles (less than 200 microns). Applying larger droplets reduces drift potential but will not prevent drift if applications are made improperly or under unfavorable environmental conditions (see Wind; Temperature and Humidity; and Temperature Inversions). Controlling droplet size: • 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 noz- zles 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 recommended practice. For aerial application, significant deflection from the horizontal airstream will increase fine droplets 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. DO NOT use nozzles producing a mist droplet spray. For aerial application, straight-stream or solid-stream nozzles oriented straight back produce the largest droplets and the lowest drift. Additives Agriculturally approved drift-reducing additives may be used to reduce fine droplets. Swath Adjustment When applications are made with a crosswind, the swath will be displaced downwind. Therefore, on the upwind and downwind edges of the field, the applicator must compen- sate for this displacement by adjusting the path of the application equipment (e.g. aircraft, ground) upwind. Swath adjustment distance should increase with increasing drift potential (higher wind, smaller droplets, etc.). Wind Drift potential is lowest between wind speeds of 3 to 10 mph. However, many factors, including droplet size and equipment type, determine drift potential at any given speed. If applying at wind speeds less than 3 mph, the applicator must determine if conditions of temperature inversion exist or stable atmospheric conditions exist at or below nozzle height. DO NOT make applications into areas of temperature inversions or stable atmospheric conditions. NOTE: Local terrain can influence wind patterns. Every applicator should be familiar with local wind patterns and how they affect spray drift. 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 con- ditions are both hot and dry. Temperature Inversions Applications should not occur during temperature inver- sions because drift potential is high. Temperature inversions restrict vertical air mixing, which causes small suspended droplets to remain in a concentrated cloud that can move in unpredictable directions because of 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 pres- ent, inversions can also be identified by the movement of smoke from a ground source or an aircraft smoke genera- tor. 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. Sensitive Areas This pesticide should only be applied when the potential for drift to adjacent sensitive areas (e.g. residential areas, bod- ies of water, known habitat for threatened or endangered species, or nontarget plants) is minimal (e.g. when wind is blowing away from sensitive areas).

Wind Erosion Avoid treating powdery, dry, or light sandy soils when con- ditions are favorable for wind erosion. Under these conditions, the soil surface should first be settled by rainfall or irrigation. Additives To improve postemergence weed control, agriculturally approved surfactants or crop oil concentrate and sprayable fertilizers (urea ammonium nitrate [DAN] or ammonium sul- fate [AMS]) may be added, particularly in dry growing conditions; refer to Table 2. Nonionic Surfactant (NIS) The standard label recommendation for normal growing conditions is 1 quart of an 80% active NIS per 100 gallons of water. Crop Oil Concentrate (COC) A crop oil concentrate must contain either a petroleum-oil or vegetable-oil base and must meet all of the following criteria: • Nonphytotoxic • Contain only EPA-exempt ingredients • Provide good mixing quality in the jar test • Successful in local experience The exact composition of suitable products will vary; however, vegetable-oil and petroleumrbil concentrates - should contain emulsifiers to provide good mixing quality. Highly refined vegetable oils have proven more satisfactory than unrefined vegetable oils. For additional information, see Compatibility Test for Mix Components. Nitrogen Source • UAN - Use 2 to 4 quarts of UAN (28%, 30%, or 32% nitrogen solution) per acre. • AMS - AMS at 2.5 pounds per acre may be substituted for UAN. Use high-quality AMS (spray grade) to avoid plugging of nozzles. Avoid use of AMS in spray volume less than 10 gallons per acre because of potential precip- itation problems. DO NOT use galvanized, brass, or aluminum application equipment (e.g. nozzles, tanks, pipes) that will contact spray solutions containing UAN or AMS. Table 2.

"Adjuvants containing crop oil concentrates may be used in between- ... crop (postharvest, fallow) applications. DO NOT use crop oil 'concentrate for postemergence in-crop applications. Tank Mixing Information Dyvel™ WG herbicide may be tank mixed with one or more registered herbicide products according to the spe- cific tank mixing instructions in this label and respective product labels. Read and follow the applicable restrictions and limitations and Directions For Use on all product labels involved in tank mixing. Always follow the most restrictive label use directions. Refer to the Crop-specific Information section for tank mixing details. DO NOT tank mix with Axial® herbicide or Discover herbicide products. Mixing Dyvel WG with postemergence grass (graminicide) herbicides may reduce the effectiveness of those products. Physical incompatibility, reduced weed control, or crop injury, may result from mixing Dyvel WG with other pesti- cides (fungicides, herbicides, insecticides, or miticides), additives, or fertilizers. Local agricultural authorities may be a source of information when using other than BASF-recommended tank mixes. Dyvel WG may be used in tank mixtures with most foliar- applied insecticides. However, DO NOT apply Dyvel WG in tank mixtures with Lorsban® insecticide. Compatibility Test for Mix Components Before mixing components, always perform a compatibility jar test.

1. For 20 gallons per acre spray volume, use 3.3 cups (800 ml) of water. For other spray volumes, adjust rates accordingly. Only use water from the intended source at the source temperature.
2. Add components in the sequence indicated in the fol- lowing mixing order instructions; use 2 teaspoons per pound or 1 teaspoon per pint of labeled use rate per acre.
3. Cap the jar and invert 10 cycles between component additions.
4. When the components have all been added to the jar, let the solution stand for 15 minutes.

( 5. Evaluate the solution for uniformity and stability. The spray solution should not have free oil on the surface, or fine particles that precipitate to the bottom, or thick (clabbered) texture. If the spray solution is not compatible, repeat the compatibility test with the addi- tion of a suitable compatibility agent. If the solution is then compatible, use the compatibility agent as directed on its label. If the solution is still incompatible, DO NOT mix the ingredients in the same tank. Mixing Order Maintain agitation throughout mixing.

1. Water - Fill tank 1/2 to 3/4 full with clean water and start agitation.
2. Inductor - If an inductor is used, rinse it thoroughly after each component has been added.
3. Products in PVA bags - Place any product contained in water-soluble PVA bags into the mixing tank. Wait until all water-soluble PVA bags have fully dissolved and the product is evenly mixed in the spray tank before continuing.
4. Water-conditioning additives (including dry and liquid fertilizers such as AMS or UAN)
5. Water-dispersible products (such as Dyvel™ WG herbicide, dry flowables, wettable powders, suspension concentrates or suspo-emulsions)
6. Water-soluble products and additives
7. Emulsifiable concentrates (including crop oil concen- trate or methylated seed oil adjuvants)
8. Remaining quantity of water Maintain agitation throughout application until spraying is completed. If the spray mixture is allowed to settle for any period of time, thorough agitation is essential to resuspend the mixture before spraying is resumed. Continue agitation while spraying. Use Restrictions • Maximum seasonal use rate - 4.2 ozs/A for fallow or wheat postemergence application. • DO NOT make more than one (1) application per crop season. • DO NOT apply to winter wheat in the fall. • DO NOT apply to wheat underseeded to forage. • Restricted-entry interval (REI) - 24 hours • DO NOT graze livestock or harvest forage for hay from treated areas for a minimum of 30 days following application. • Preharvest interval (PHI) - DO NOT harvest grain for 60 days following application. • DO NOT apply through any type of irrigation equipment. • DO NOT treat irrigation ditches or water used for crop irrigation or domestic purposes. Crop Rotation and Emergency Replanting Intervals Wheat may be planted anytime after a fallow application or crop failure. Cereals (barley, oats, triticale), corn, cotton, sorghum, and soybean may be planted 30 days after application. All other crops may be planted 120 days after application. Crop-specific Information Postharvest, Fallow, Crop Stubble, and Set-aside Dyvel WG can be applied either postharvest in the fall, spring, or summer; during the fallow period; or to crop stubble/set-aside acres. Apply Dyvel WG as a broadcast or spot treatment to emerged and actively growing weeds after crop harvest (postharvest) and before a killing frost, or in the fallow cropland or crop stubble the following spring or summer. See Crop Rotation and Emergency Replanting Intervals section for the required interval between application and planting. Application Rate and Timing Apply 4.2 ozs of Dyvel WG per acre. For best perform- ance, apply Dyvel WG when annual weeds are less than 3 inches and perennial weeds are in early regrowth stage (less than 4 inches) in late summer or fall following a mow- ing or tillage treatment. An adjuvant system (refer to Additives section for details) is required for optimum broadleaf activity. Avoid disturbing treated areas following application. Treatment may not kill weeds that develop from seed or underground plant parts such as rhizomes or bulblets after application. Use a sequential herbicide appli- cation or other cultural practice to control later emerging weeds. Tank Mixtures Broad-spectrum control of grass weeds and/or additional broadleaf weeds will usually require a tank mix with another herbicide. Dyvel WG may be tank mixed or applied sequentially with one or more of, but not limited to, the fol- lowing herbicide products: • Clarity" herbicide • Paramount0 herbicide • 2,4-D • glyphosate (e.g. Roundup* herbicide) Apply Dyvel WG to wheat postemergence only. DO NOT apply to winter wheat in the fall. For best performance, apply Dyvel WG when annual weeds are small (less than 3 inches) and actively growing. An adjuvant system (refer to Additives section for details) is required for optimum broadleaf activity. Application of Dyvel WG to wheat during Jj IJ 10

(periods of rapid growth may result in crop leaning. This / C condition is temporary and will not reduce crop yield. -^ Application to wheat may be made by aerial application using 2 gallon of water or more per acre. Where dense foliage is present, use more than 2 gallons of water per acre. Postemergence Application Apply Dyvel™ WG herbicide at 2.1 to 4.2 ozs/A between the 2-leaf stage and emergence of the fourth tiller. DO NOT use crop oil concentrate for postemergence in-crop application. Tank Mixtures Broad-spectrum control of broadleaf and grass weeds will usually require a tank mix with another herbicide. Dyvel WG may be tank mixed or applied sequentially with one or more of, but not limited to, the following herbicide products: • Beyond® herbicide (for Clear-field® wheat only) • Clearmax® herbicide (for Clear-field wheat only) • 2,4-D amine • MCPA • Sulfonylurea-based herbicide (e.g. Ally® herbicide, Express® herbicide, Harmony® Extra herbicide, Peak* herbicide) DO NOT tank mix or use in the same season with Axial® herbicide or Discover® herbicide products. 11
