General Information Prowl® 3.3 EC herbicide is a selective herbicide for con- trolling most annual grasses and certain broadleaf weeds as they germinate. Refer to Table 1 for a complete list of controlled weeds. Prowl 3.3 EC will not control estab- lished weeds. Unusually cold, excessively wet, or hot and dry conditions that delay germination or extend germination over a long period of time can reduce weed control. Overapplication can result in crop-stand loss, crop injury, or soil residues. Uneven application or improper soil incorporation can decrease weed control or cause crop injury. Soil incorpo- ration deeper than recommended can reduce weed control. Seedling diseases, cold weather, excessive moisture, shal- low or deep planting, low or high soil pH, high soil salt concentration, or drought can weaken seedlings and 5 plants and increase the possibility of crop damage from Prowl® 3.3 EC herbicide. Under these conditions, crop yields can be reduced. Table 1.

Mode of Action Pendimethalin, the active ingredient in Prowl 3.3 EC, is a Group 3 (WSSA)/Group K1 (HRAC) herbicide belonging to the dinitroaniline chemistry class. Prowl 3.3 EC is a meristematic inhibitor that interferes with meristematic plant cell division or mitosis inhibiting germinating seedling growth. Herbicide Resistance Management Prowl 3.3 EC is a Group 3 herbicide. Any weed popula- tion may contain or develop plants naturally resistant to Prowl 3.3 EC and other Group 3 herbicides. Weed spe- cies with resistance to Group 3 may eventually dominate the weed population if Group 3 herbicides are used repeatedly in the same field or in successive years as the primary method of control for targeted species. This may result in partial or total loss of control of those species by Prowl 3.3 EC or other Group 3 herbicides. To delay herbicide resistance consider: • Avoiding the consecutive use of Prowl 3.3 EC or other target site-of-action Group 3 herbicides that have a sim- ilar target site of action on the same weed species. • Using tank mixes or premixes with herbicides from differ- ent target-site-of-action groups as long as the involved products are all registered for the same use, have differ- ent sites of action, and are both effective at the tank mix or prepack rate on the weed(s) of concern. - Basing herbicide use on a comprehensive IPM (Integrated Pest Management) program including cul- tural and mechanical methods. - Monitoring treated weed populations for loss of field efficacy, and control of escapes with effective alterna- tive herbicides or mechanical methods. - Identify weeds present in the field through scouting and field history and understand their biology. 6 The weed-control program needs to consider all of the weeds present. - Scout fields prior to application to identify the weed species present and their growth stage to determine if the intended application will be effective. - Scout fields after application to verify the treatment was effective. - Suspected herbicide-resistance weeds may be identi- fied by these indicators: 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 par- ticular weed species; and 3. Surviving plants mixed with controlled individuals of the same species. • If resistance is suspected, treat weed escapes with an herbicide with a different MOA and/or use nonchemical methods to remove escapes, as practical, with the goal of preventing further seed production. • Report any incidence of non-performance of this product against a particular weed species to your local BASF representative. • Contacting your local extension specialist, certified crop advisors, and/or manufacturer for herbicide resistance management and/or integrated weed management directions for specific crops and resistant weed biotypes. Application Rate Use rates for Prowl® 3.3 EC herbicide when used alone, in tank mix, or sequential applications are given in Crop-specific Information . Use rates of this product vary by soil texture and organic matter. See Table 2 for soil texture groupings used in this label. Table 2. Soil Texture Groups COARSE MEDIUM FINE sands loamy sands sandy loams sandy clay loams* sandy clays loams silt loams silts silty clay loams* silty clays clay loams clays * Sometimes considered transitional soils and may be classified as either medium- or fine-textured soils. Peat and Muck soils: Prowl 3.3 EC may be used on peat and muck soils, but weed control may be inconsis- tent and/or reduced. Use maximum labeled use rate allowed in the specific crop. Application Timings Prowl 3.3 EC will provide most effective weed control when applied by ground or aerial equipment and subse- quently incorporated into soil within 7 days after application by rainfall, sprinkler irrigation, or mechanical tillage prior to weed seedling emergence from soil. Prowl 3.3 EC can also be applied through chemigation, including flooded basin irrigation systems. Prowl 3.3 EC is recommended for preplant surface, preplant incorporated, surface incorporated, preemergence, early postemer- gence, postemergence incorporated (CULTI-SPRAY) or layby treatment. See Crop-specific Information for spe- cific application directions by crop. Preplant Surface Applications. For use in minimum till- age or no-tillage production systems, apply Prowl 3.3 EC alone or in tank mixes up to 45 days before planting. When making early preplant surface applications (15 to 45 days prior to planting), Prowl 3.3 EC should be tank mixed or followed by a postemergence herbicide application. Rain- fall or sprinkler irrigation within 7 days after application is required to move this product into the upper soil surface where weed seeds germinate. Preplant Incorporated Applications. Apply Prowl 3.3 EC and incorporate into the upper (1 inch to 2 inches) soil surface up to 60 days before planting. Use an implement capable of giving uniform incorporation; two-pass incorporation usually results in a more consistent result. Surface Incorporated Applications. Uniformly apply Prowl 3.3 EC as broadcast or banded treatment to soil surface underneath established trees and/or in ground areas between trees rows. Within 7 days after application, incorporate into upper (1 inch to 2 inches) soil surface using either rainfall, sprinkler irrigation, or shallow mechani- cal incorporation using an implement capable of giving uniform incorporation; two-pass mechanical incorporation usually results in a more consistent result. Preemergence Surface Applications. Broadcast treat- ment uniformly to the soil surface at planting and up to 2 days after planting. Rainfall, sprinkler irrigation, or shal- low mechanical incorporation within 7 days after application is required to move this product into the upper soil surface where weed seeds germinate. If adequate rainfall or irrigation does not occur and weed seedling emergence begins, a shallow cultivation or rotary hoeing will improve performance. Early Postemergence Applications. Prowl 3.3 EC must be applied prior to weed seedling emergence or in a tank mix with products that control the emerged weeds. Refer to Crop-specific Information for specific poste- mergence application recommendations by crop. Postemergence Incorporated Applications (CULTI- SPRAY). Prior to application, crop must be cultivated in such a manner as to throw at least one inch of soil over the base of the crop plants. This will prevent direct contact of Prowl 3.3 EC and the zone of brace root formation. Prowl 3.3 EC must be applied broadcast with a ground sprayer when crop is at least 4 inches tall up to layby. Use drop nozzles if crop foliage will prevent uniform coverage of the soil surface within the rows. Thoroughly and uni- formly incorporate Prowl 3.3 EC treatments into the soil with: (1) a sweep-type or rolling cultivator set to provide thor- ough incorporation in the top 1 inch of soil, or (2) adequate overhead irrigation water or rainfall. See Crop-specific Information (Corn and Grain 7 Sorghum) for more details on (CULTI-SPRAY) application. Layby Application. Apply Prowl® 3.3 EC herbicide directly to the soil between rows as a directed spray fol- lowing the last normal cultivation (layby). See Crop-specific Information for more details on layby application. Split Applications. Prowl 3.3 EC may be applied pre- plant incorporated up to 60 days prior to planting and followed by a preemergence application at planting or up to 2 days after planting. The total amount of Prowl 3.3 EC applied per acre per season cannot exceed the highest labeled rate for any given soil type. See Crop-specific Information for more details on split applications. Fall Applications. Prowl 3.3 EC may be used in fall application programs in certain crops. See Crop-specific Information for details on fall application timing. Application Instructions Prowl 3.3 EC may be applied using either water or spray- able fluid fertilizer (such as straight 32-0-0 or 28-0-0) as the spray carrier. Additionally, Prowl 3.3 EC may be impregnated on dry bulk fertilizer. Sprayable fluid fertilizer as a carrier is NOT recommended for use after crop emer- gence unless the typical fertilizer burn symptoms on the crop are acceptable. Spray Mix Compatibility Test If liquid fertilizer/herbicide(s) mixture separates in the spray tank, clogged equipment and uneven application can result. Always predetermine the compatibility of Prowl 3.3 EC alone or with other herbicides based on the following compatibility “jar test”: 1. Add 1 pint of fertilizer to a quart jar. 2. Add 1 to 4 teaspoon(s) of the Dry Flowable (DF), Wetta- ble Powder (WP), Aqueous Solution (AS), Flowable (F) or Liquid (L) formulation (depending on mixing ratio required) to the liquid fertilizer. The number of teaspoons of the formulation to add can be determined by the fol- lowing formula: lbs or pts of product/acre x1 1 . 4= number of teaspoons of herbicide to add to 1 pint of fertilizer gallons of fertilizer/acre 3. Close the jar and agitate until the herbicide(s) are evenly dispersed in the liquid fertilizer. If the materials DO NOT disperse well, it may be necessary to slurry the chemi- cals in water before adding to the fertilizer. 4. After dispersing the materials, add appropriate number of teaspoons of Prowl 3.3 EC to the jar and shake well. Add water soluble concentrate herbicides to the mixture last and agitate. Let the mixture stand for 30 minutes and then observe the results. Look for signs of separa- tion: an oily layer or globules, sludge, flakes or other precipitates. 5. Evaluate compatibility. (a) If the herbicide(s) and liquid fertilizer mixture does not separate, use this mixture in your spray tank. (b) If the mixture separates but mixes readily with shak- ing, the mixture can be used provided that good agitation is maintained in the spray tank. (c) If separation of the mixture occurs and agitation does not correct this problem, a compatibility agent is needed. 6. If the need for a compatibility agent is demonstrated, the following procedure is recommended: Using a clean quart jar, repeat step 1 above and add 1/2 teaspoon of the compatibility agent to the liquid fertilizer. Mix well and repeat steps 2, 3 and 4. If separation or precipita- tion occurs with the compatibility agent, DO NOT use Prowl 3.3 EC with that specific liquid fertilizer. Aerial Applications Uniformly apply in 5 or more gallons of water per acre. Ground Applications (Broadcast) Uniformly apply with properly calibrated ground equipment in 10 or more gallons of water per acre or 20 or more gal- lons of liquid fertilizer per acre. Keep the bypass line on or near the bottom of the tank to minimize foaming. Nozzle and in-line screens must be no finer than 50 mesh. Ground Applications (Band) Uniformly apply the broadcast equivalent rate and volume per acre. To determine these: Band Width in Inches x Broadcast Rate per Acre = Band Rate per AcreRow Width in Inches Band Width in Inches x Broadcast Volume per Acre = Band Volume per AcreRow Width in Inches Ground Applications (Dry Bulk Fertilizer) Apply Prowl 3.3 EC/dry bulk fertilizer mixtures only with ground equipment. DO NOT impregnate Prowl 3.3 EC onto coated ammonium nitrate or limestone because these materials will not absorb the herbicide. Dry fertilizer blends containing mixtures of ammonium nitrate or limestone may be impregnated with Prowl 3.3 EC. A minimum of 200 pounds of impregnated dry bulk fertilizer, excluding the weight of ammonium nitrate or limestone, must be applied per acre. Calculate the amount of Prowl 3.3 EC to be impregnated on a ton of dry bulk fertilizer based on the rate of fertilizer to be applied per acre: 2000 x Pints of Prowl 3.3 EC (Recommended Rate per Acre) = Pints of Prowl 3.3 EC per Ton of Fertilizer Pounds of Dry Fertilizer per Acre To impregnate Prowl 3.3 EC on bulk fertilizer, use a closed rotary-drum mixer or other commonly used dry bulk fertilizer blender equipped with suitable spray equip- ment. Spray nozzles must be placed to provide uniform coverage of Prowl 3.3 EC onto the fertilizer during mixing. Apply the Prowl 3.3 EC/dry bulk fertilizer mixture with an accurately calibrated dry fertilizer spreader. The Prowl 3.3 EC/dry bulk fertilizer mixture must be spread uniformly on the soil surface. 8 Chemigation Applications via Sprinkler Irrigation Systems Prowl ® 3.3 EC herbicide may be applied as a chemiga- tion treatment through sprinkler irrigation systems. Refer to Crop-specific Information sections for individual crops. DO NOT apply Prowl 3.3 EC via chemigation to crops unless specified in Crop-specific Information section. Apply this product ONLY through a sprinkler irrigation sys- tem of the following type: center pivot, lateral move, end tow, side (wheel) roll, traveler, big gun, solid set, or hand move. DO NOT apply this product through any other type of sprinkler irrigation system. Uniform distribution of Prowl 3.3 EC-treated irrigation water is the sole responsibility of the applicator and is required to avoid crop injury, lack of herbicide effective- ness or illegal pesticide residues in the crop. If you have any questions about calibration, you should contact state extension service specialists, equipment manufacturers, or other experts. The system must be properly calibrated (with water only) to ensure that the amount of Prowl 3.3 EC applied corre- sponds to the recommended rate. Apply Prowl 3.3 EC in 1/2 to 3/4 inches of water during the first sprinkler set (use at least 1 inch of water in the states of Texas, New Mexico and Oklahoma). Maintain agitation in the injection nurse tank to keep a uniform herbicide suspension during appli- cation. When application is complete, flush the system with water. Chemigation Instructions (for low volume micro sprinklers) Output of low volume sprinkler = 4 to 50 gallons per hour (gph) per emitter. Point of application MUST be above ground. Irrigation system should run a sufficient amount of time prior to Prowl 3.3 EC injection to have all emitters func- tioning properly. After system is operating properly, length of injection should be such that at one period of time during the injection, the first and last emitters in the system contain Prowl 3.3 EC-treated water. Add Prowl 3.3 EC to the supply tank already filled with the volume of water required for the injection period. Maintain proper agitation in Prowl 3.3 EC injection tank. Prowl 3.3 EC should be mixed in clean water and injected down-line from filters. Following Prowl 3.3 EC injection, system should be flushed for a period of time sufficient to clear the line of Prowl 3.3 EC. (If Prowl 3.3 EC application is made during a normal irrigation cycle, injection should be made during the last stage.) Chemigation Calibration (for low volume micro sprinklers) Calculation of use rate is based on wetted area around emitters - NOT on tree acres. To determine correct amount of Prowl 3.3 EC, use the following formula: 1. Treated area per each emitter = A A = 3.14 x (radius x radius) 2. The area in square feet wet in each acre = B B = A x emitters/acre 144 3. The total area (in square feet) wet by your system = C C = B x acres covered by system. 4. Rate per treated acre of Prowl 3.3 EC (based on length of control desired) = R Amount of Prowl 3.3 EC to inject = S S = C x R = qts of Prowl 3.3 EC 43,560 Example: If the average distance from emitter to perimeter of wet- ted area measured one inch below soil surface is 13 inches, then A = 3.14 x (13" x 13"), and A = 530.7 square inches. If there are 300 emitters per acre, then B = 530.7 x 300 and B = 1105.6 square feet wetted per acre.144 If the system covers 20 acres, then C = C = 1105.6 square feet per acre x 20 acres and 22,112 square feet wetted by system. If the desired application rate per treated acre is 2.4 qts of Prowl 3.3 EC, then S = 22,112 x 2.4 and S = 1.2 qts of Prowl 3.3 EC should be injected into the system.43,560 Special Instructions for Chemigation 1. DO NOT apply when wind speed favors drift beyond the area intended for treatment. 2. DO NOT connect an irrigation system used for pesticide application to a public water system unless the pesticide label-prescribed safety devices for public water systems are in place. 3. 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. 4. The pesticide injection pipeline must contain a function- al, automatic quick-closing check valve to prevent the flow of fluid back toward the injection pump. It 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. 5. The sprinkler chemigation system must contain a func- tional check valve, vacuum relief valve, and low-pressure 9 drain appropriately located on the irrigation pipeline to prevent water source contamination from backflow. In addition, 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. 6. The sprinkler chemigation system must contain func- tional interlocking controls to automatically shut off the pesticide injection pump when the water pump motor stops, or in cases where there is no water pump, when the water pressure decreases to the point where pesti- cide distribution is adversely affected. 7. The irrigation line or water pump must include a func- tional pressure switch that will stop the water pump motor when the water pressure decreases to the point where pesticide distribution is adversely affected. Chemigation Systems Connected to Public Water Systems 1. Public water system means a system for the provision to the public of piped water for human consumption if such system has at least 15 service connections or regularly serves an average of at least 25 individuals daily at least 60 days out of the year. 2. Chemigation systems connected to public water sys- tems must contain a functional, reduced-pressure zone backflow preventer (RPZ) or the functional equivalent in the water supply line upstream from the point of pesti- cide introduction. As an option to the RPZ, the water from the public water system should be discharged into a reservoir tank prior to pesticide introduction. There shall be a complete physical break (air gap) between the outlet end of the fill pipe and the top or overflow rim of the reservoir tank of at least twice the inside diameter of the fill pipe. 3. All chemigation systems connected to public water sys- tems must also follow restrictions listed in the preceding section titled Chemigation. Applications via Flooded Basin Irrigation Systems Prowl ® 3.3 EC herbicide may be applied via flooded basin irrigation systems, but only to the following crops: bearing and nonbearing fruit and nut trees, nonbearing vineyards, and alfalfa grown for forage, hay or seed production. Use Instructions and Precautions for Flooded Basin Irrigation 1. Prowl 3.3 EC may be applied through flooded basin irrigation systems designed to uniformly distribute irri- gation water along the soil surface. Solid set systems utilizing tall riser for overhead application are excluded. 2. Follow all label recommendations for Prowl 3.3 EC regarding rates per acre, timing of application, and crop-specific restrictions and limitations. 3. DO NOT connect an irrigation system used for pesti- cide application to a public water system unless the pesticide label-prescribed safety devices for public water systems are in place. 4. 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. 5. BASF recommends that Prowl 3.3 EC is mixed with water at a 1:1 ratio in the injection nurse tank to assist with product flowability. Maintain agitation in the injec- tion nurse tank to keep a uniform herbicide suspension during application. When application is complete, flush the system with water. 6. Tail water (runoff water) from flood irrigation that con- tains Prowl 3.3 EC should be re-circulated and contained in the field of initial application or used only on adjacent tree or vine crops or alfalfa for which Prowl 3.3 EC is registered for this type of application. 7. Systems using a gravity-flow pesticide dispensing sys- tem must meter the pesticide in the water at the head of the field downstream of a hydraulic discontinuity, such as a drop structure or weir box, to decrease potential for water source contamination from backflow water. 8. Systems utilizing a pressurized water and pesticide injection system must meet the following requirements: • The system must contain a functional check valve, vacuum-relief valve, and low-pressure drain appropri- ately located in the irrigation pipe to prevent water source contamination from backflow. • The pesticide injection pipeline must contain a func- tional automatic quick closing check valve to prevent flow of fluids back towards the injection pump. • 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. • The system must contain a functional interlocking control to automatically shut off the pesticide injec- tion pump when the water pump stops. • The irrigation pipe or water pump must include a functional pressure switch, which will stop the pump motor when the water pressure decreases to the point where pesticide distribution is adversely affected. • Systems must use a metering pump, such as a posi- tive displacement injection pump (e.g. diaphragm pump), of effective design and constructed of materi- als that are compatible with pesticides and capable of being fitted with a system interlock. • Any alternative to the above safety devices must con- form to the list of EPA-approved alternative devices. 9. Regularly measure the flow in the field to ensure the correct amount of Prowl 3.3 EC is being metered into the irrigation water and also regularly monitor to ensure that treated water is being uniformly distributed across the field. Flow rates through metering devices and distribution of Prowl 3.3 EC can vary with water temperature and speed of water flow across the field. 10 10. Uniform distribution of Prowl® 3.3 EC herbicide- treated irrigation water is the sole responsibility of the applicator and is required to avoid crop injury, lack of herbicide effectiveness, or illegal pesticide residues in the crop. 11. If you have questions about calibration, you should contact state extension service specialists, equip- ment manufacturers or other experts. Mandatory Spray Drift Management Ground Boom Applications • Applicators must only apply with the nozzle height rec- ommended by the manufacturer, but no more than 3 ft above the ground or crop canopy. • Applicators are required to use a medium or coarser droplet size (ASAE S572). • DO NOT apply when wind speeds exceed 15 mph at the application site. • DO NOT apply during temperature inversions. Boomless Ground Applications • Applicators are required to use a medium or coarser droplet size (ASAE S572) for all applications. • DO NOT apply when wind speeds exceed 15 mph at the application site. • DO NOT apply during temperature inversions. Aerial Applications • Applicators are required to use a medium or coarser droplet size (ASABE S641). • Applicators must use 1/2 swath displacement upwind at the downwind edge of the field. • Nozzles must be oriented so the spray is directed toward the back of the aircraft. • DO NOT release spray at a height greater than 10 ft above the crop canopy, unless a greater application height is necessary for pilot safety. • 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 not exceed 65% of the wingspan for fixed wing aircraft or 75% of the rotor diameter for helicopters. Otherwise, the boom length must not exceed 75% of the wingspan for fixed wing aircraft or 90% of the rotor diameter for helicopters. • DO NOT apply during temperature inversions. Spray Drift Advisories The applicator is responsible for avoiding off-site spray drift. Be aware of nearby nontarget sites and environmen- tal 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 • 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. • Pressure - Use the lowest spray pressure recommend- ed for the nozzle to produce the target spray volume and droplet size. • Spray Nozzle - Use a spray nozzle that is designed for the intended application. Consider using nozzles designed to reduce drift. Controlling Droplet Size - Aircraft • Adjust Nozzles - Follow nozzle manufacturer’s recom- mendations for setting up nozzles. 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. Boomless Ground Applications Setting nozzle at the lowest effective height will help to reduce the potential for spray drift. Shielded Sprayers Shielding the boom or individual nozzles can reduce spray drift. Consider using shielded sprayers. Verify that the shields are not interfering with the uniform deposition of the spray on the target area. Temperature and Humidity When making applications in hot and dry conditions, use larger droplets to reduce effects of evaporation. Temperature Inversion Drift potential is high during a temperature inversion. Tem- perature 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 applica- tions during temperature inversions. Wind Drift potential generally increases with wind speed. AVOID APPLICATIONS DURING GUSTY WIND CONDITIONS. Applicators need to be familiar with local wind patterns and terrain that could affect spray drift. Sensitive Areas This 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 endan- gered species, or nontarget crops or plants) is minimal (e.g. when wind is blowing away from the sensitive areas). 11 Additives Spray adjuvants have little or no influence on performance of Prowl® 3.3 EC herbicide when applications are made prior to weed emergence. However, several tank mixes with Prowl 3.3 EC require adjuvants to improve burndown of emerged weeds. Therefore, surfactants, liquid fertilizer (28%, 30%, or 32% UAN (urea ammonium nitrate) or ammonium sulfate), or crop oil concentrate may be used with Prowl 3.3 EC tank mixes applied preplant, pre- emergence, or early postemergence to the crop. Follow the adjuvant recommendations on the tank mix partner’s label. When an adjuvant (or a specific adjuvant product, such as a drift control agent) is to be used with this product, the use of a Chemical Producers and Distributors Association (CPDA) certified adjuvant is recommended. The recom- mended adjuvants must contain ingredients accepted by the EPA. Tank Mixing Information Prowl 3.3 EC may be applied in a tank mix or a sequential application with other herbicides registered for use in a given crop. Refer to the companion label for weeds con- trolled in addition to Prowl 3.3 EC alone. When using tank mixtures or sequential applications with Prowl 3.3 EC, always read the companion product label(s) to determine the specific use rates by soil types, weed species, and weed or crop growth stage. In addition, fol- low all precautions and restrictions including state and local use restrictions that may apply to specific products. Always follow the most restrictive label. Uses with Other Products (Tank Mixes) If this product is used in combination with any other prod- uct except as specifically recommended in writing by BASF, then BASF shall have no liability for any loss, dam- age, or injury arising out of its use in any such combination not so specifically recommended. If used in combination recommended by BASF, the liability of BASF shall in no manner extend to any damage, loss, or injury not directly caused by the inclusion of the BASF product in such com- bination use, and in any event shall be limited to return of the amount of the purchase price of the product. Always perform a mixing test to check the compatibility of Prowl 3.3 EC with all potential tank mix partners. Mixing Instructions 1. Fill tank 1/2 to 3/4 full with clean water or liquid fertilizer and agitate. Prior to mixing Prowl 3.3 EC or Prowl 3.3 EC tank mixtures in liquid fertilizer, refer to appropriate label sections for recommended uses in liquid fertilizer, application instructions, and compatibil- ity determinations. NOTE: Prowl 3.3 EC will NOT mix in high salt formu- lation fertilizers, such as 10-34-0. When utilizing high salt formulation fertilizers as the spray carrier, use one of the following: (a) Pre-slurry Prowl 3.3 EC in water prior to adding to tank; use 1:1 ratio of water to Prowl 3.3 EC. (b) Add water to fertilizer solution prior to adding Prowl 3.3 EC. The amount of water should be equal to or greater than the amount of Prowl 3.3 EC to be used. 2. Prowl 3.3 EC Alone When using Prowl 3.3 EC alone, add Prowl 3.3 EC to the partially filled tank while agitating and then fill the remainder of the tank with water or liquid fertilizer. 3. Prowl 3.3 EC Tank Mixes Add the tank mixture ingredients in the order listed below prior to adding Prowl 3.3 EC. (for tank mixtures with Butyrac ® 200, Gramoxone® Extra or glyphosate, see mixing instructions at the end of this section): (a) Wettable Powder (WP) formulations - Make a slurry of the WP in water (1:2 ratio). Add the slurry slowly into the partially filled tank while agitating. (b) Dry Flowable (DF)/Water Dispersible Granule (WDG) formulations - Add the granules to the partially filled tank while agitating. Make a slurry of the granules in water before adding to liquid fertilizer. (c) Flowable (F) formulations - Add the F formulation to the partially filled tank while agitating. (d) Water Soluble Concentrate (WSC) formulations - Add the WSC formulation to the partially filled tank while agitating. (e) Emulsifiable Concentrate (EC) formulations  - Add the EC formulation to the partially filled tank while agitating. After complete mixing, add Prowl 3.3 EC to the tank. (f) NOTE: For tank mixes including Butyrac 200, Gramoxone Extra or glyphosate: After complete mixing of Prowl 3.3 EC, continue filling the sprayer with water and add Butyrac or Gramoxone Extra or glyphosate near the end of the filling process. If Gramoxone Extra is included in the tank mixture, add 8 ozs of non-ionic surfactant per 100 gallons of total spray mixture as the last ingredient in the tank. Fill the remainder of the tank with water or liquid fertilizer while agitating. 4. Thorough and continuous sprayer-tank agitation MUST be maintained during mixing and spraying of Prowl 3.3 EC. 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. Cleaning Spray Equipment Clean application equipment thoroughly by using a strong detergent or commercial spray cleaner according to the manufacturer’s directions, and then triple rinsing the equip- ment before and after applying this product. 12 Restrictions and Limitations • DO NOT exceed the maximum labeled rate for any soil type. • Prowl® 3.3 EC herbicide will not control established weeds. Destroy emerged weeds prior to application. • Prowl 3.3 EC is most effective in controlling weeds mechanically incorporated or when incorporated into the weed germination zone by adequate rainfall or overhead irrigation after application. • When using tank mixtures with Prowl 3.3 EC, always read the companion product label(s) to determine the specific use rates by soil types, weed species, and weed or crop growth stage. In addition, follow all precautions and restrictions including state and local use restrictions that may apply to specific products. Always follow the most restrictive label. • In the event of a crop loss due to adverse weather condi- tions or other reasons, any crop registered for a preplant incorporated application of Prowl 3.3 EC can be replanted without adverse effects the same year (see Crop-specific Information for exceptions). If replanting is necessary, DO NOT work the soil deeper than the treated zone. • Refer to Crop-specific Information for crop-specific preharvest intervals and feeding and grazing restrictions. Crop Rotation Restrictions • Use of Prowl 3.3 EC in accordance with label directions is expected to result in normal growth of rotational crops in most situations; however, various environmental and agronomic factors, such as arid conditions, make it impossible to eliminate all risks associated with the use of this product and, therefore, rotational crop injury is always possible. Soil characteristics and environmental conditions which may contribute to crop stress that may be accentuated by the use of Prowl 3.3 EC include: coarse soils, compaction, high salinity, eroded knolls/ hilltops, cold and/or wet soils, drought, and heavy rainfall soon after application. • When Prowl 3.3 EC is used in tank mix or sequential combinations, refer to labels of other herbicides for addi- tional rotational crop restrictions. • Restrictions for rotational cropping after the use of Prowl 3.3 EC are dependent on the application use rate of Prowl 3.3 EC in the primary crop. The user should thoroughly read the following restric- tions to determine the rotational crops for their specific situation, according to application use rate. I. Rotational Crop Restrictions Following Applica- tions of Prowl 3.3 EC to Field and Row Crops 1. Application Rate less than or equal to 4.8 pts/A (2.0 lbs ai/A): (a) Crops which are labeled for preplant incorporated application may be planted the same season in which Prowl 3.3 EC was applied. (b) Sugar beets, Red beets and Spinach To avoid crop injury, DO NOT plant sugar beets, red beets or spinach for 12 months following a spring application of Prowl 3.3 EC or 14 months following a fall application of Prowl 3.3 EC. These crops should not be planted for 18 months following a spring application of Prowl 3.3 EC or 20 months following a fall application of Prowl 3.3 EC if rainfall or irrigation was not suffi- cient to produce a crop. To ensure thorough mixing of soil prior to planting sugar beets, red beets and spinach, land should be plowed using a moldboard plow to a depth of 12 inches. (c) Proso millet, Sorghum (milo), and Annual or Perennial grass crops or mixtures Proso millet, sorghum (milo), and annual or perenni- al grass crops or mixtures should not be planted for 10 months after a spring application of Prowl 3.3 EC or 12 months after a fall application of Prowl 3.3 EC except in the following conditions: In the states of Minnesota, North Dakota and South Dakota, these crops should not be planted for 18 months following a spring application of Prowl 3.3 EC or 21 months following a fall applica- tion of Prowl 3.3 EC. To avoid the possibility of crop injury in areas that receive less than 20 inches of rainfall or irrigation to produce a crop, these crops should not be planted for 18 months following a spring application of Prowl 3.3 EC or 20 months following a fall applica- tion of Prowl 3.3 EC if rainfall or irrigation was not sufficient to produce a field or row crop. (d) Wheat and Barley Wheat and barley may be planted 4 months after an application of Prowl 3.3 EC, except under the following conditions: If less than 12 inches of rainfall or overhead irriga- tion was received between application and rotational crop planting, wheat should not be plant- ed before 12 months after a spring application of Prowl 3.3 EC or 14 months after a fall application of Prowl 3.3 EC. In dryland areas and/or areas where irrigation is necessary to produce the crop treated with Prowl 3.3 EC, DO NOT plant winter wheat or 13 barley as a follow crop if crop failure/destruction occurs and land is fallowed during the summer. (e) All Other Rotational Crops Not Specifically Addressed Above Crops, other than those to which Prowl ® 3.3 EC herbicide may be applied as a preplant incorpo- rated treatment, may be planted the year following application of Prowl 3.3 EC, except under the fol- lowing condition: If rainfall or irrigation was not sufficient to produce a crop, delay planting for 18 months following a spring application of Prowl 3.3 EC or 20 months following a fall application of Prowl 3.3 EC. 2. Application Rate greater than 4.8 pts/A (2.0 lbs ai/A): In the growing season following application of Prowl 3.3 EC to field and row crops at greater than 4.8 pts/A, plant only those crops for which Prowl 3.3 EC is labeled for preplant incorporated treatment or crop injury may occur. DO NOT plant other crops for 24 months. II. Rotational Crop Restrictions Following Applica- tions of Prowl 3.3 EC to Orchard, Grove, and Vineyard Crops In the growing season following application of Prowl 3.3 EC to bearing fruit and nut trees, plant only those crops for which Prowl 3.3 EC is labeled for pre- plant incorporated treatment or crop injury may occur. DO NOT rotate to other crops (except for nut crops, fruit trees, or grapes) for 24 months following a Prowl 3.3 EC application to bearing fruit or nut trees. Use Area NORTHERN STATES SOUTHERN STATES Crop-specific Information Crop Injury Disclaimer: Prowl 3.3 EC use may result in crop injury, loss or damage to certain crops under a num- ber of conditions, including but not limited to agronomic, cultural, mechanical, and environmental. Numerous risks of loss or damage to certain crops may be associated with the use of Prowl 3.3 EC even when directions for use are followed completely. The user or grower should take all such risks into consideration before deciding to apply the product. BASF recommends testing on a small por- tion of the target crop to determine if damage is likely to occur. Each grower who is considering the product for such use should test Prowl 3.3 EC in order to determine its suitability. A grower should use Prowl 3.3 EC only to the extent that in his sole opinion the benefit of Prowl 3.3 EC use outweighs the potential injury to the grower’s crop. In addition, many factors can affect crop growth and/or yield, including but not limited to, insects, diseases, weed competition, poor seed quality, improper planting depth, mechanical cultivation, poor weather (such as freezing or excessive wind, rain, heat, or cold), lack of or excessive moisture, crusting, fertility, or hardpans. Risk of loss or damage to crops may be associated with the use of Prowl 3.3 EC and contribute to poor stands due to failure of crop to emerge, swelling of roots or other below-ground plant parts, less vigorous plant growth and development, and reduction in yield potential. Prowl 3.3 EC may also cause injury to sensitive rotational crops. ALFALFA (Grown for Forage, Hay, or Seed Production) Prowl 3.3 EC may be applied by ground, air, chemigation, flooded basin irrigation systems, or on dry bulk fertilizer. Use Methods, Timings and Rates Established Alfalfa for Forage/Hay (defined as alfalfa planted in the fall or spring that has gone through a first cutting/mowing): Uniformly apply Prowl 3.3 EC at a broadcast rate of 1.2 to 4.8 quarts per acre prior to weed emergence. Applications can be made in the fall after the last mowing/cutting, during winter dormancy, in the spring, or between cuttings. Applications should be made prior to the alfalfa reaching 6 inches in regrowth. Established Alfalfa Grown for Seed Production (defined as alfalfa planted in the fall or spring that has gone through a summer season of cutting/mowing): Uniformly apply Prowl 3.3 EC at a broadcast rate of 1.2 to 4.8 quarts per acre prior to weed emergence in one of the following ways: 1. Apply to dormant established alfalfa. 2. Apply before alfalfa exceeds 10 inches in height after first mowing/beating. 3. Once the alfalfa reaches 10 inches in height or if the alfalfa has been mowed/beaten two or more times, Prowl 3.3 EC must be applied with drop nozzles directing the spray so that there is little to no contact with the foliage. Seedling Alfalfa (defined as alfalfa planted in the fall or spring which has NOT gone through a cutting/mowing): Uniformly apply Prowl 3.3 EC at a broadcast rate of 1.2 to 2.4 pints per acre prior to weed emergence. Applications can be made once the seedling alfalfa has reached the 2nd trifoliate stage of growth. Applications should be made prior to the alfalfa reaching 6 inches in growth. 14 Alfalfa Stand Establishment: Apply Prowl® 3.3 EC herbicide at a broadcast rate of 1.2 to 1.8 pints per acre as a preplant incorporated or preemergence treatment in direct-seeded alfalfa. Some crop stand reduction and stunting may occur with this use of Prowl 3.3 EC; howev- er, reduced weed competition will allow establishment of a quality stand. Use the lower rates on coarse-texture soil or in lower rainfall areas (receiving less than 20 inches of rain- fall and irrigation a year). - Preplant incorporated: Uniformly incorporate Prowl 3.3 EC into the top 2 to 3 inches of the final seed- bed prior to planting. - Preemergence: Apply directly after drill seeding alfalfa. Alfalfa should be planted into a seedbed that is firm and free of clods. Chemigation Applications Prowl 3.3 EC may be applied through sprinkler irrigation systems.

SPECIAL CROP USE RESTRICTIONS The pesticide applicator, the producer of the crop, and the seed conditioner must be aware that use of this product according to this labeling is deemed a nonfeed/nonfood use. If the applicator of this pesticide is not the producer, the applicator should provide a copy of this labeling to the producer of the crop. Producers of this crop who use this product, or cause the product to be used on a field they operate, should provide a copy of this pesticide label to the seed conditioner. Consequently, no portion of this carrot seed crop, includ- ing but not limited to green chop, hay, pellets, meal, whole seed, cracked seed, roots, bulbs, foliage and seed screen- ings, may be used or distributed for food or feed purposes. Processed carrot seed from a field treated with this prod- uct must bear a specific tag or conspicuous container labeling, or if shipped in bulk, on the shipment invoice or bill of lading, with the following statement: “Not for human consumption or animal feed.” All seed screenings from seed processing shall be disposed of in such a manner that the screenings cannot be distributed or used for human food or animal feed purposes. The seed conditioner shall keep records of screening dis- posal for three years from the date of disposal and shall furnish the records immediately upon request. Conditioner 16 disposal records shall consist of documentation of on-farm disposal, disposal at a controlled dumpsite, incinerator, composter or other equivalent disposal site and shall include the lot numbers, amount of material disposed of, the grower(s), and the date of disposal. CORN (Field, Pop, Seed, Sweet) Prowl® 3.3 EC herbicide may be applied by ground, air or chemigation. Prowl 3.3 EC may be applied in conventional, minimum, or no-till as a preemergence, postemergence, or poste- mergence incorporated (CULTI-SPRAY) application in field corn. Prowl 3.3 EC may be applied in conventional tillage as a preemergence or postemergence application in sweet corn, seed corn, or popcorn. Regardless of tillage system, plant corn at least 1 -1/2 inches deep and completely cover with soil. In conventional tillage systems, plant into a seedbed that is firm and free of clods and trash. Use only where adequate tillage is practiced to provide good soil coverage of the corn seed. In no-till systems, utilize a no-till planter that is capable of planting through crop residue. The use of no-till planters under conditions that do not allow good soil coverage of the corn seed can result in reduced crop stand or injury if Prowl 3.3 EC contacts the germinating corn seed. Check equipment to ensure good seed coverage. Prowl 3.3 EC or Prowl 3.3 EC tank mix combination treatments are most effective in controlling weeds when adequate rainfall or overhead irrigation is received within 7 days after application. If cultivation is necessary because of soil crusting or weed germination, use shallow tillage and make certain corn seeds are below the tilled area. Additional Weeds Controlled: In addition to the weeds listed in Table 1, Prowl 3.3 EC will control the following weeds in corn with CULTI-SPRAY application: wild proso millet and shattercane. Use Methods and Timings Preemergence - Apply after planting but before weeds and crop emerge. Postemergence - Apply postemergence until field corn is 30 inches tall (20 to 24 inches tall for pop, seed and sweet corn) or in the V8 growth stage, whichever is more restric- tive. If the corn canopy prevents applications from reaching the soil, use drop nozzles and apply as a directed spray. CULTI-SPRAY - Apply Prowl 3.3 EC alone or Prowl 3.3 EC plus atrazine when field corn is at least 4 inches tall until last cultivation (layby). Prowl 3.3 EC plus atrazine must be applied before the field corn reaches 12 inches in height. DO NOT exceed 1.2 lbs ai per acre of atrazine, as specified on the atrazine label. Under situations of low rainfall or soil moisture when deep germinating weeds such as shattercane or field sandbur are anticipated, mechanical incorporation will provide best results. If culti- vation is needed after application and incorporation of Prowl 3.3 EC, the depth of cut should be no deeper than the depth of cut used to incorporate. Chemigation Applications Prowl 3.3 EC may be applied through sprinkler irrigation systems.

COTTON Prowl 3.3 EC may be applied by ground, air, or chemiga- tion in conventional, minimum, stale seedbed, or no-till as a preplant surface, preplant incorporated, preemergence, or layby application in cotton. Preplant surface, preemergence, and layby treatments are most effective in controlling weeds when adequate rainfall or overhead irrigation is received within 7 days after appli- cation. A shallow cultivation is recommended if soil crusting or soil compaction occurs. If weeds begin to ger- minate or adequate moisture is not received within 7 days 17 after application, use shallow tillage (rotary hoe or light har- row) and make sure cotton seeds are below tilled area. The use of a postemergence herbicide treatment may be required to control weed escapes at planting or following cotton emergence. Additional Weeds Suppressed: In addition to the weeds listed in Table 1, Prowl ® 3.3 EC herbicide will suppress Russian thistle in the state of Arizona.

If irrigating immediately after Prowl 3.3 EC application at the preemergence through loop stage, DO NOT irrigate in excess of 0.5 inch of water. 23 • DO NOT plant sugar beets, red beets, spinach, winter wheat, or winter barley as rotational crops on muck soils for 12 months from the time of last application if more than 3.6 pints per acre of Prowl ® 3.3 EC herbicide is applied to the onion crop. • If loss of onion crop occurs, DO NOT replant any crop other than onions in muck soil during the same cropping year and DO NOT work the soil deeper than 2 inches. PEANUTS Prowl 3.3 EC may be applied by ground, air, or chemigation. Prowl 3.3 EC may be applied preplant incorporated in peanuts. Prowl 3.3 EC may also be applied preemergence to pea- nuts grown under overhead irrigation. DO NOT use in California. Use Methods and Timings Preplant Incorporated - Apply Prowl 3.3 EC up to 60 days prior to planting and incorporate within 7 days after applications. Preemergence - Apply Prowl 3.3 EC at planting or up to 2 days after planting and before crop emergence. To pre- vent decreased crop pegging, adequate incorporation must be achieved by applying a minimum of 0.75 inch of overhead irrigation or rainfall within 48 hours of application. Chemigation Applications Prowl 3.3 EC may be applied through sprinkler irrigation systems. Follow all recommendations, special instructions and precautions in the general section covering Chemigation in Spraying Instructions . Use Rates Region Rate (pts/A) Texas, Oklahoma and New Mexico 1.2 to 2.4 Other peanut growing states* 2.4 * For heavy weed infestations, especially of Texas panicum, up to 3.6 pts/A of Prowl 3.3 EC can be used in Alabama, Georgia or Florida. POTATOES Prowl 3.3 EC may be applied by ground, air, or chemigation. Prowl 3.3 EC may be applied preemergence, pre- emergence incorporated, or early postemergence in potatoes. Additional Weeds Controlled: In addition to the weeds listed in Table 1, Prowl 3.3 EC will control stinging nettle in potatoes. Use Methods and Timings Preemergence - Apply Prowl 3.3 EC after planting, but before potatoes and weeds emerge, or after dragoff. Preemergence Incorporated - Apply Prowl 3.3 EC and incorporate after planting but before potatoes and weeds emerge. Where dragoff is practiced, apply Prowl 3.3 EC and incorporate before, at, or after dragoff, but before potatoes and weeds emerge. Incorporate Prowl 3.3 EC within 7 days of application. Prowl 3.3 EC must be thor- oughly and uniformly incorporated into the top 1 to 2 inches of soil. Mechanical incorporation is not required if adequate rainfall for good crop and weed emergence occurs or irrigation is received within 7 days after applica- tion. Care must be taken so that incorporation equipment does not damage seed pieces or elongating sprouts. Early Postemergence - Apply Prowl 3.3 EC from crop emergence to the 6-inch stage of growth. DO NOT apply Prowl 3.3 EC postemergence if potatoes are under stress from cold/wet or hot/dry conditions or crop injury may occur. Chemigation Applications Prowl 3.3 EC may be applied through sprinkler irrigation systems. Apply Prowl 3.3 EC preemergence after plant- ing, after dragoff, or early postemergence through sprinkler irrigation systems. Follow all recommendations, special instructions and precautions in the general section cover- ing Chemigation in Spraying Instructions . Use Rates Soil Texture < 3% Organic Matter > 3% (pts/A) Coarse 1.8 1.8 Medium 2.4 3.6 Fine 3.6 3.6 Restrictions and Limitations • DO NOT apply to sweet potatoes or yams. • DO NOT apply preplant. • DO NOT make more than one application of Prowl 3.3 EC per season. • Application of Prowl 3.3 EC on White Rose variety pota- toes during or followed by cool and/or wet weather conditions may result in crop injury. RICE Prowl 3.3 EC may be applied as a pre-flood, pre- emergence application in dry-seeded or drilled rice or as a delayed preemergence application in drilled dry-seeded rice or as an early postemergence application in dry-seeded rice. Treatments may be applied to conven- tional, reduced or minimum tillage, and no-till (stale seedbed) rice. The seedbed should be firm and free of clods and must be prepared to allow for good seed cover- age. The use of a planter under conditions that do not allow good soil coverage of the rice seed can result in 24 reduced stand or stunting if Prowl® 3.3 EC herbicide contacts germinating rice seed. Additional Weeds Controlled: In addition to the weeds listed in Table 1, Prowl 3.3 EC will control the following weeds in rice: junglerice and sprangletop. Use Methods and Timings Pre-Flood, Preemergence - Prowl 3.3 EC may be applied for preemergence weed control as a pre-flood, pre-rice germination herbicide in lightly incorporated dry-seeded rice or on drilled rice. SEEDING DIRECTIONS: For all rice seed incorporation methods, seed must be incorporated shallowly or no more than 1 inch below soil surface. Seed left on the surface may be injured or killed by Prowl 3.3 EC. However, it is recommended that 15 to 20% of seed total be visible at surface in order to ensure that seed is not cov- ered too deeply. Seeding rates should be increased by a percentage corresponding to the amount of seed left on the surface. Adjust seeding ratios to meet individual prac- tices, incorporation depths and field conditions. EXAMPLE: Target seeding rate is 150 lbs per acre. If approximately 15% of seed is left on soil surface, seeding rate should then be increased 22.5 lbs per acre to 177.5 lbs per acre. Seeding depths can be affected by soil textures, tillage practices, irrigation, and methods of mechanical incorpo- ration. Seed that is incorporated either mechanically and/or by irrigation flush must remain at a shallow depth of no more than 1 inch below the soil surface. Fields where rice seed is incorporated too deeply will experience reduced crop stands. Following are examples of typical implements that can be used for rice seed incorporation: rice roller/ridger, ring roll- er, light harrow, or flat roller. Regardless of the implement or method of incorporation used, seed incorporation must be less than 1 inch below the soil surface. After rice seed is incorporated, uniformly apply to soil sur- face as broadcast spray the tank mixture of Prowl 3.3 EC at 2.4 pints per acre plus FirstChoice ® SafeGuardTM spray adjuvant at 1.6 pints per acre. Use of Prowl 3.3 EC without tank mixing with FirstChoice SafeGuard spray adjuvant can result in crop injury and loss of rice stand. After herbicide application, flush field with irrigation water with method best employed to facilitate a thorough soak- ing of field and a rapid drain. Tail water (runoff water) from flood irrigation that contains Prowl 3.3 EC should be re-circulated and contained in the field of initial application or used only on adjacent crops for which Prowl 3.3 EC (or other pendimethalin-based products) is registered for use. Rice seed covered with water for longer than 8 days may result in reduced stand and weed control. Delayed Preemergence - Apply Prowl 3.3 EC alone or with tank mix partner for delayed preemergence weed control in grain-drilled, dry-seeded rice. Apply Prowl 3.3 EC alone or in tank mixture to levees after the levees are pulled and planted. Exposed seeds that come in contact with Prowl 3.3 EC may be injured. Apply only when growing conditions favor vigorous rice growth. The seedbed should have adequate moisture for seed germi- nation. Not for use in California. Uniformly apply the recommended rate of Prowl 3.3 EC after rice planting and before rice and weed emergence (spiking). Apply after the rice seed has absorbed water and germinated and after the soil has been previously sealed over the seed by at least 1 inch of rainfall or by irrigation (flush). If the soil has not been sealed by rain or flush, apply when 80 percent of germinated seeds have a primary root (radicle) or shoot at least 1/2-inch long. If there is insuffi- cient moisture, flushing is recommended before Prowl 3.3 EC application to supply moisture for root (radi- cle) initiation and for vigorous rice and weed growth. If applied to soil prior to these conditions or to cracked soil, stand reduction or stunting of rice may occur. Under some conditions, use of gibberellic acid-treated seed, heavy rain- fall after application, or flushing after application may result in herbicide injury to rice. Rice can overcome moderate injury with appropriate cultural practices. Due to the residual activity of Prowl 3.3 EC, this treatment may be applied if rice is too small to maintain a flood on the field for weed control. However, proper water manage- ment practices must be followed for normal rice growth and activity of Prowl 3.3 EC. Early Postemergence - Apply Prowl 3.3 EC as a tank mix partner. Base applications on weed and crop size guidelines of the tank mix partner. DO NOT apply to fields with standing water. If necessary, fields may be flushed prior to treatment to produce vigorous rice and weed growth. Since soil and weeds must be completely exposed to spray coverage, no flood water should be on the field at the time of application. Cloddy soil, standing water (pud- dles) at the time of application, or cracks in the soil that form after application may result in reduced weed control. Because of residual activity of Prowl 3.3 EC, this treat- ment may be applied if rice is too small to maintain a flood on the field for weed control. However, proper water man- agement practices must be followed for normal rice growth and activity of Prowl 3.3 EC. Since the residual activity of Prowl 3.3 EC is activated by moisture, Prowl 3.3 EC is most effective in controlling emerging weeds when adequate rainfall or irrigation (flush) is received within 7 days after application. 25 Use Rates Delayed Preemergence Applications Soil Texture Rate (pts/A) Sands, loamy sands DO NOT USE Sandy loams 1.8 Loams, silt loams, silts, sandy clay loams 2.4 Silty clay loams, clay loams, sandy clays, silty clays, clays 2.4 Early Postemergence Application Soil Texture Rate (pts/A) Coarse 1.8 Medium 2.4 Fine 2.4 Restrictions and Limitations • DO NOT apply Prowl® 3.3 EC herbicide as a pre- flood, preemergence treatment in rice unless tank mixed with FirstChoice ® SafeGuardTM spray adjuvant. • DO NOT apply Prowl 3.3 EC through any type of irriga- tion system. • DO NOT apply in liquid fertilizer. • DO NOT use on water-seeded rice except as specified in other BASF labeling. • DO NOT apply to rice fields if fields are used for fish pro- duction, especially catfish or crayfish farming. • DO NOT use water containing Prowl 3.3 EC residues from rice cultivation to irrigate food or feed crops that are not registered for use with Prowl 3.3 EC. • In case of a crop failure due to weather conditions or dis- ease following treatment with Prowl 3.3 EC alone or in a tank mixture, only drilled dry-seeded rice may be imme- diately replanted; however, the grower assumes all risks and consequences associated with replanting of rice because there is the potential for stand reduction or stunting. A 10 percent increase in seeding rate is recom- mended. Replant seed below the herbicide layer because reduced stand or stunting may occur if Prowl 3.3 EC contacts germinating rice seed. DO NOT replant with gibberellic acid-treated seed. DO NOT reap- ply Prowl 3.3 EC alone or in a tank mixture. • DO NOT apply Prowl 3.3 EC and then flush for germination. • DO NOT apply to stressed rice. Stress factors include cold or hot temperature extremes, excessive moisture or drought, problem soils, poor field drainage, or deep water after application. • DO NOT apply early preemergence nor preplant incor- porated as severe rice injury is possible. • DO NOT feed forage or graze livestock in treated fields. SOYBEANS Prowl 3.3 EC may be applied in conventional, minimum, or no-till as a fall surface, fall incorporated, preplant sur- face, preplant incorporated, or preemergence application in soybeans.

SUGARCANE Use Methods and Timings Prowl 3.3 EC may be applied preemergence through layby to plant or ratoon sugarcane. Applications may be made band or broadcast. Although there may be adequate crop tolerance for postemergence applications at layby, the spray must be directed under the sugarcane canopy in order to obtain effective weed control. Prowl 3.3 EC must be thoroughly and uniformly incorpo- rated into the soil with either (a) mechanical incorporation equipment as outlined below, or (b) with rainfall or irriga- tion, if rainfall or irrigation is adequate for good crop and weed emergence and received within 7 days after applica- tion. If rainfall or irrigation is not obtained, Prowl 3.3 EC should be mechanically incorporated. Mechanical Incorporation Prowl 3.3 EC should be applied to loosened beds and incorporated into the top 1 to 2 inches of soil within 7 days after application. Use Rates Use Area Broadcast Rate1 (pts/A) All states, except Hawaii 4.8 to 7.2 Muck soils (Florida only) 4.8 to 9.7 Hawaii 4.8 to 9.7 1 Use the high rate if: clay soils; no mechanical incorporation is planned; heavy weed populations are anticipated; itchgrass infesta- tion is anticipated; shaving is planned. Restrictions and Limitations • DO NOT exceed 14.4 pints of Prowl 3.3 EC per acre in one growing season. • DO NOT use less than 11 gallons of water as a carrier when applying Prowl 3.3 EC for weed control. • Ratoon sugarcane must be lightly shaved in early spring to remove the old stubble before incorporation over the line of sugarcane is possible. Carefully adjust equipment to incorporate without causing excessive damage to emerging shoots. • DO NOT make aerial applications at close-in because complete and uniform coverage cannot be obtained. • DO NOT apply through any type of irrigation system. • DO NOT apply within 90 days of harvest. • DO NOT graze treated fields or feed treated forage or fodder to livestock. 27 SUNFLOWERS Prowl® 3.3 EC herbicide may be applied preplant incor- porated in all states. Fall preplant incorporated applications may be made in North Dakota, South Dakota and Minne- sota only. Prowl 3.3 EC may be applied preemergence in conventional tillage sunflowers, except in the state of California. Plant sunflowers 1.5 inches to 2 inches deep and completely cover with soil. Use Methods and Timings Preplant Incorporated (Spring) - Apply up to 60 days prior to planting and incorporate within 7 days after application. Preplant Incorporated (Fall applications in North Dakota, South Dakota and Minnesota) - Apply Prowl 3.3 EC and immediately incorporate in late fall prior to planting sunflowers the following spring. Apply Prowl 3.3 EC in the late fall when soil temperatures are 45° F or below but before the ground freezes. DO NOT apply when the air temperature is below 45º F. Prior to sunflower planting in the spring, fields treated with Prowl 3.3 EC should receive at least one shallow addi- tional incorporation. Spring incorporation should be at an angle to the last tillage operation. Preemergence - Apply Prowl 3.3 EC at planting or up to 2 days after planting. Preemergence applications of Prowl 3.3 EC to sunflowers may increase the likelihood of crop injury, especially when sunflowers are grown in stress situations, such as compacted soils. Decreased herbicide performance compared to preplant incorporated applica- tions may also result from a preemergence application. If dry conditions with limited precipitation exist or unseason- ably cool temperatures following planting are forecast, apply Prowl 3.3 EC prior to planting and mechanically incorporate with tillage.

WHEAT Prowl® 3.3 EC herbicide may be applied by ground or air. Prowl 3.3 EC may be applied preemergence, delayed preemergence, or postemergence to wheat for weed con- trol in fall, winter or spring seeded wheat. Use Methods and Timings Apply to a seedbed that is firm and free of clods and trash. The seedbed MUST be prepared to ensure good seed coverage by the soil and seed-to-soil contact. Use high quality seed. When applications of Prowl 3.3 EC are intended to be made preemergence or delayed pre- emergence, plant seed at least 1 inch deep to avoid possible crop injury, but not too deep for proper germina- tion. When applications of Prowl 3.3 EC are intended to be made postemergence, plant seed at least 0.5 inch to 1.0 inch to avoid crop injury. Uniformly apply Prowl 3.3 EC as a preemergence, or delayed preemergence (after wheat seed has germinated), or postemergence treatment from the 1st-leaf stage of wheat until before the flag leaf is visible/emerged for weed control. Prowl 3.3 EC should be applied prior to weed emergence. EMERGED WEEDS WILL NOT BE CON- TROLLED BY THIS TREATMENT. Adequate rainfall or irrigation within 7 days after application will provide the most consistent weed control. For control of established weeds, Prowl 3.3 EC may be tank mixed with any postemergence herbicide registered for use in wheat. Prowl 3.3 EC will provide residual con- trol of the weeds listed in this label. Always perform a mixing test to check the compatibility of Prowl 3.3 EC with all potential tank mix partners.
