Prowl H2O is a meristematic inhibitor that interferes with meristematic plant cell division or mitosis inhibiting germinating seedling growth. Herbicide Resistance Management Prowl H2O is a Group 3 herbicide. Any weed population may contain or develop plants naturally resistant to Prowl H2O and other Group 3 herbicides. Weed species with resistance to Group 3 may eventually dominate the weed population if Group 3 herbicides are used repeated - ly 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 H2O or other Group 3 herbicides. To delay herbicide resistance consider: • Avoiding the consecutive use of Prowl H2O or other tar- get site-of-action Group 3 herbicides that have a similar 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 (Integrat- ed Pest Management) program including cultural and mechanical methods. • Monitoring treated weed populations for loss of field effi - cacy, and control of escapes with effective alternative herbicides or mechanical methods. • Identify weeds present in the field through scouting and field history and understand their biology. The weed- control program needs to consider all of the weeds present. • Scout fields prior to application to identify the weed spe - cies present and their growth stage to determine if the intended application will be effective.

7 • Scout fields after application to verify the treatment was effective. • Suspected herbicide-resistance weeds may be identified by these indicators:

1. Failure to control a weed species normally controlled by the herbicide at the dose applied, especially if con - trol 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 non-chemical 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® H2O herbicide when used alone, in tank mix, or for sequential applications are given in Crop-specific Information . Use rates of this product vary by soil texture and organic matter. See Table 5 for soil texture groupings used in this label. DO NOT apply more than the maximum labeled rate of Prowl H2O for any soil type. Table 5. 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 medium-texture or fine-texture soils. For peat and muck soils. Prowl H2O 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 H2O will provide most effective weed control when applied by ground or aerial equipment and subsequently incorporated into soil by rainfall, sprinkler irrigation, or mechanical tillage before weed seedling germination. Prowl H2O can also be applied through chemigation, including flooded basin irrigation systems. Prowl H2O may be applied preplant surface, preplant incorporated, surface incorporated, preemergence, early postemer - gence, postemergence incorporated (CULTI-SPRAY), or by layby treatment. See Crop-specific Information for spe- cific application directions and restrictions by crop. Preplant Surface Application. For use in minimum- tillage or no-tillage production systems, apply Prowl H2O alone or in tank mixes within 45 days of planting. When making early preplant surface application (15 to 45 days before planting), Prowl H2O should be tank mixed or fol- lowed by a postemergence herbicide application. Rainfall or sprinkler irrigation after application is required to move this product into the upper soil surface where weed seeds germinate. Preplant Incorporated Application. Apply Prowl H2O and incorporate into the upper (1 inch to 2 inches) soil surface within 60 days of planting. Use an implement capable of giving uniform incorporation; two-pass incorpo - ration usually results in a more consistent result. Surface Incorporated Application. Uniformly apply Prowl H2O as broadcast or banded treatment to soil sur- face underneath established trees and/or in ground areas between trees rows. Incorporate into upper (1 inch to 2 inches) soil surface using rainfall, sprinkler irrigation, or shallow mechanical incorporation using an implement capable of giving uniform incorporation; two-pass mechanical incorporation usually results in a more consis - tent result. Preemergence Surface Application. Broadcast treat- ment uniformly to the soil surface at planting and up to 2 days after planting (refer to Crop-specific Information section for exceptions). Rainfall, sprinkler irrigation, or shal- low mechanical incorporation 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, or soil crusting or soil compaction has occurred, and weed seedling emergence begins, a shal - low cultivation or rotary hoeing or light harrow will improve performance. Make sure that crop seeds are below the tilled soil surface area. Early Postemergence Application. Prowl H2O must be applied before weed seedling emergence or in a tank mix with products that control the emerged weeds. Refer to Crop-specific Information for specific postemer- gence application instructions by crop. Postemergence Incorporated Application (CULTI- SPRAY). Before application, crop must be cultivated in such a manner as to throw at least 1 inch of soil over the base of the crop plants. This will prevent direct contact of Prowl H2O and the zone of brace root formation. Prowl H2O 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 H2O treatments into the soil:

1. With a sweep-type or rolling cultivator set to provide thorough incorporation in the top 1 inch of soil, or
2. With adequate overhead irrigation water or rainfall. See Crop-specific Information (Corn and Grain Sorghum) for more details on (CULTI-SPRAY) application.

8 Layby Application. Apply Prowl® H2O herbicide directly to the soil between rows as a directed spray after the last normal cultivation (layby). See Crop-specific Information for more details on layby application. Split Application. Prowl H2O  may be applied preplant incorporated within 60 days of planting and followed by a preemergence application at planting or up to 2 days after planting (refer to Crop-specific Information section for exceptions). The total amount of Prowl H2O  applied per acre per year cannot exceed the highest labeled rate for any given soil type. See Crop-specific Information for more details on split applications. Fall Application. Prowl H2O  may be used in fall applica- tion programs in certain crops. See Crop- specific Information for details on fall application timing. Application Instructions Prowl H2O may be applied using water or sprayable fluid fertilizer (including straight 32-0-0 or 28-0-0) as the spray carrier. DO NOT apply Prowl H2O after crop emergence (postemergence) in sprayable liquid fertilizers. Additionally, Prowl H2O may be impregnated on dry bulk fertilizer. For all applications, avoid overlapping that could result in pos - sible crop injury. Spray Mix Compatibility Test If liquid fertilizer and/or herbicide(s) mixture separates in the spray tank, clogged equipment and uneven application can result. Always predetermine the compatibility of Prowl H2O 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), wettable powder (WP), aqueous solution (AS), flowable (F), or liq- uid (L) formulation (depending on mixing ratio required) to the liquid fertilizer. To calculate teaspoons of the for- mulation to add: lbs or pts of product/acre x 11.4 = teaspoons of herbicide to add to 1 pint of fertilizergallons 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 H2O to the jar and shake well. Add water soluble concentrate herbicides to the mixture last and agitate. Let the mixture stand for 30 minutes; then observe the results. Look for signs of separation: 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 if 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, BASF recommends the following procedure: Using a clean quart jar, repeat step 1 above and add 1/2 tea- spoon of the compatibility agent to the liquid fertilizer. Mix well and repeat steps 2, 3, and 4. If separation or precipitation occurs with the compatibility agent, DO NOT use Prowl H2O with that specific liquid fertilizer. Aerial Application Uniformly apply in 5 or more gallons of water per acre. Spray Drift Management for Aerial Applications • 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. • Applicators are required to use a medium or coarser droplet size (ASABE S572.1). • 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. • 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 apply during temperature inversions. Ground Application (Broadcast) Uniformly apply in 10 or more gallons of water per acre or 20 or more gallons 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 Application (Band) Uniformly apply the broadcast equivalent rate and volume per acre. Calculate: 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 Spray Drift Management for Ground Applications: • Applicators must only apply with the nozzle height rec - ommended by the manufacturer, but no more than 3 feet above the ground or crop canopy. • Applicators are required to use a medium or coarser droplet size (ASABE S572.1).

9 • DO NOT apply when wind speeds exceed 15 miles per hour at the application site. • DO NOT apply during temperature inversions. Ground Application (Dry Bulk Fertilizer) Apply Prowl® H2O herbicide/dry bulk fertilizer mixtures only with ground equipment. See Crop-specific Information for crops suitable for dry bulk fertilizer appli - cations. DO NOT impregnate Prowl H2O onto coated ammonium nitrate or limestone because these materials will not absorb the herbicide. Dry fertilizer blends contain - ing mixtures of ammonium nitrate or limestone may be impregnated with Prowl H2O . A minimum of 200 pounds of impregnated dry bulk fertili zer, excluding the weight of ammonium nitrate or limestone, must be applied per acre. Calculate the amount of Prowl H2O impregnated on a ton of dry bulk fertili zer based on the rate of fertili zer to be applied per acre: 2000 x Prowl H2O (rate per acre) = Prowl H2O per ton of fertilizerpounds of dry fertilizer per acre To impregnate Prowl H2O on bulk fertilizer, use a closed rotary-drum mixer or other commonly used dry bulk fertili - zer blender equipped with suitable spray equipment. Spray nozzles must be placed to provide uniform coverage of Prowl H2O onto the fertilizer during mixing. Apply the Prowl H2O /dry bulk fertilizer mixture with a cali - brated dry fertilizer spreader. The Prowl H2O /dry bulk fertilizer mixture must be spread uniformly on the soil surface. Chemigation Application via Sprinkler Irrigation and Drip Irrigation Systems Prowl H2O may be applied as a chemigation treatment through sprinkler irrigation and drip irrigation systems. Refer to Crop-specific Information sections for individual crops. DO NOT apply Prowl H2O via chemiga- tion 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. Apply this product ONLY through a drip irrigation system that has emitters above the soil surface. DO NOT apply this product through any other type of sprinkler irrigation or drip irrigation system. Uniform distribution of Prowl H2O -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. If you have any questions about calibration, contact State Extension Service special - ists, equipment manufacturers, or other experts. The system must be calibrated (with water only) to ensure the amount of Prowl H2O applied corresponds to the specified rate. Apply Prowl H2O in 1/2 to 3/4 inch of water during the first sprinkler set (use at least 1 inch of water in the states of New Mexico, Oklahoma, and Texas). BASF recommends mixing Prowl H2O with water at a 1:1 ratio in the injection nurse tank to assist with product flowability. Maintain agitation in the injection nurse tank to keep a uni - form herbicide suspension during application. When application is complete, flush the system with water. Chemigation Instructions (for low-volume micro sprinklers) Output of low-volume sprinkler equals 4 to 50 gallons per hour (gph) per emitter. Point of application MUST be above ground. Irrigation system must run a sufficient amount of time before Prowl H2O injection to have all emitters functioning properly. After system is operating properly, length of injec- tion must be such that at one period of time during the injection, the first and last emitters in the system contain Prowl H2O -treated water. Add Prowl H2O to the supply tank already filled with the volume of water required for the injection period. Maintain agitation in Prowl H2O injection tank. Mix Prowl H2O in clean water and inject down-line from filters. After Prowl H2O injection, flush system for a period of time sufficient to clear the line of Prowl H2O . (If Prowl H2O is applied during a normal irrigation cycle, make injection 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 calculate amount of Prowl H2O :

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 H2O (based on length of control desired) = R Amount of Prowl H2O to inject = S S = C x R = qts of Prowl H2O 43,560

10 Example: If the average distance from emitter to perimeter of wetted area measured 1 inch below soil surface is 13 inches, then A = 3.14 x (13 inches x 13 inches) 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 acre144 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 2.0 qts of Prowl® H2O herbicide, then S = 22,112 x 2.0 and S = 1.0 qt = amount of Prowl H2O to inject into the system43,560 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. Recirculate and/or contain tail water (runoff water) from chemigation that contains Prowl H2O in the field in a cistern or holding reservoir from the initial application and/or use only on adjacent, approved crops for which Prowl H2O is registered for this type of application.
5. 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 automatically or manually shut down.
6. The sprinkler chemigation system must contain a func - tional check valve, vacuum relief valve, and low- pressure drain appropriately located on the irrigation pipeline to prevent water source contamination from backflow. In addition, systems must use a metering pump, including 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 . The sprinkler chemigation system must contain function - al 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
8. 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.
9. 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, discharge the water from the public water system 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 res- ervoir tank of at least twice the inside diameter of the fill pipe.
10. All chemigation systems connected to public water sys- tems must also follow restrictions listed in the preceding sections involving Chemigation. Application via Flood, Flooded Basin, or Gravity Flow Irrigation Systems Prowl H2O may be applied via flood, flooded basin, or gravity flow irrigation systems, but only to the following crops: alfalfa, bearing and nonbearing fruit and nut trees, bearing and nonbearing bushberries and caneberries, bearing and nonbearing olive trees, bearing and nonbear - ing vineyards, bearing and nonbearing small fruit climbing vines, and nonbearing date palm. Use Instructions and Restrictions for Flood, Flooded Basin, and Gravity Flow Irrigation
11. Prowl H2O may be applied through flood, flooded basin, or gravity flow irrigation systems designed to uniformly distribute irrigation water along the soil sur- face. Solid set systems using tall riser for overhead application are excluded.
12. Follow all label directions for Prowl H2O regarding rates per acre, timing of application, and crop-specific restrictions and precautions.
13. 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.
14. A person knowledgeable of the chemigation system and responsible for its operation, or under the supervi - sion of the responsible person, shall shut the system down and make necessary adjustments should the need arise.
15. BASF recommends that Prowl H2O is mixed with water at a 1:1 ratio in the injection nurse tank to assist with product flowability. Maintain agitation in the injection nurse tank to keep a uniform herbicide suspension during application. When application is complete, flush the system with water.

11 6. 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, includ- ing a drop structure or weir box, to decrease potential for water source contamination from backflow water. 7. Tail water (runoff water) from flood, flooded basin, or gravity flow irrigation that contains Prowl® H2O herbicide must be recirculated and/or contained in the field in a cistern or holding reservoir from the initial application and/or used only on adjacent approved crops for which Prowl H2O is registered for this type of application. 8. Systems using a pressurized water and pesticide injec - tion 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 toward 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 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, including a positive 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 H2O is metered into irrigation water and also regularly monitor to ensure treated water is uniformly distributed across the field. Flow rates through metering devices and distribution of Prowl H2O can vary with water temperature and speed of water flow across the field. 10. Uniform distribution of Prowl H2O -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. 11. For questions about calibration, contact State Exten - sion Service specialists, equipment manufacturers or other experts. 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 must remain level with the crop and have minimal bounce. Release Height - Aircraft Higher release heights increase 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.

12 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. Additives Spray adjuvants have little or no influence on performance of Prowl® H2O herbicide when applications are made before weed emergence. However, several tank mixes with Prowl H2O require adjuvants to improve burndown of emerged weeds. Therefore, surfactants, liquid fertilizer (28%, 30%, or 32% UAN [urea ammonium nitrate] or AMS [ammonium sulfate]), or crop oil concentrate (COC) may be used with Prowl H2O tank mixes applied preplant, pre- emergence, or early postemergence to the crop. Follow the adjuvant directions on the tank mix partner’s label. The adjuvants must contain ingredients accepted by the Envi- ronmental Protection Agency. When an adjuvant is to be used with this product, BASF recommends the use of a Chemical Producers and Dis - tributors Association certified adjuvant. Tank Mixing Information It is the pesticide user’s responsibility to ensure that all products in the listed mixtures are registered for the intended use. Read and follow the applicable restrictions and limitations and directions for use on all product labels involved in tank mixing. Users must follow the most restric - tive directions for use and precautionary statements of each product in the tank mixture. Prowl H2O may be tank mixed or applied sequentially with other herbicide products registered for use in any labeled crop found in this label for a broader spectrum of residual weed control and/or control of emerged weeds. Refer to the tank mix product labels to confirm that the respective tank mix products are registered for use on the labeled crop. Read and follow tank mix product labels for application instructions, use restrictions and precautions, and rotational cropping guidance. The most restrictive labeling applies to tank mixes. Always perform a mixing test to check the compatibility of Prowl H2O 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. Before mixing Prowl H2O or Prowl H2O tank mixes in liquid fertilizer, refer to appropriate label sections for specified uses in liquid fertilizer, application instructions, and compatibility determinations. NOTE: Prowl H2O will NOT mix in high salt formulation fertilizers, including 10-34-0. When using high salt for- mulation fertilizers as the spray carrier, use one of the following: a. Pre-slurry Prowl H2O in water before adding to tank; use 1:1 ratio of water to Prowl H2O . b. Add water to fertilizer solution before adding Prowl H2O . The amount of water must be equal to or more than the amount of Prowl H2O to be used.
2. Prowl H2O Alone When using Prowl H2O alone, add Prowl H2O to the partially filled tank while agitating; then fill the remainder of the tank with water or liquid fertilizer.
3. Prowl H2O Tank Mixes Add the tank mix ingredients in the following order before adding Prowl H2O : a. Wettable Powder (WP) formulations. Make a slur- ry 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 par- tially 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. Add Prowl H2O to the partially filled tank while agitating. e. Water-soluble Concentrate (WSC) formulations. Add the WSC formulation to the partially filled tank while agitating. f. Emulsifiable Concentrate (EC) formulations. Add the EC formulation to the partially filled tank while agitating. 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 H2O . 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. Cleaning Spray Equipment Clean application equipment thoroughly by using a strong detergent or commercial spray cleaner according to the manufacturer’s directions; then triple rinse the equipment before and after applying this product. Use Precautions • Prowl H2O will not control established weeds. Destroy emerged weeds before application. • Prowl H2O is most effective in controlling weeds when mechanically incorporated or when incorporated into the weed germination zone by adequate rainfall or overhead irrigation after application. • In the event of a crop loss because of adverse weather conditions or other reasons, any crop registered for a preplant incorporated application of Prowl H2O 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.

13 Use Area Rotational Crop Restrictions • Use of Prowl® H2O herbicide in accordance with label directions is expected to result in normal growth of rota- tional crops in most situations; however, various environmental and agronomic factors, including arid con - ditions, make it impossible to eliminate all risks associated with the use of this product and, therefore, rotational crop injury is always possible. Soil characteris - tics and environmental conditions which may contribute to crop stress that may be accentuated by the use of Prowl H2O include: coarse soils, compaction, high salinity, eroded knolls/hilltops, cold and/or wet soils, drought, and heavy rainfall soon after application. • When Prowl H2O is used in tank mix or sequential com - binations, refer to label of other herbicides for additional rotational crop restrictions. • After harvest of furrow-irrigated crops, thoroughly mix the soil by plowing or deep disking to minimize the potential for herbicide carryover to the following crop. • Refer to Crop-specific Information for specific rota- tional restrictions when Prowl H2O is applied to specific crops. • Restrictions for rotational cropping after the use of Prowl H2O depend on the application use rate of Prowl H2O in the primary crop. The user must thoroughly read the following restrictions to deter - mine the rotational crops for the specific situation, according to application use rate. For field and row crops, see the table following. Orchard, Grove, and Vineyard Crops In the growing season after application of Prowl H2O to bearing fruit and nut trees, bushberries, caneberries, or grapes, plant only those crops for which Prowl H2O is labeled for preplant incorporated treatment or crop injury may occur. DO NOT rotate to other crops (except for fruit and nut trees, bushberries, caneberries, or grapes) for 24 months after Prowl H2O application.

15 Crop-specific Information Crop Injury. Prowl ® H2O herbicide 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 en vironmental. Numerous risks of loss or damage to certain crops may be associated with the use of Prowl H2O even when directions for use are followed completely. The user or grower needs to 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 prod- uct for such use should test Prowl H2O to determine its suitability. A grower should use Prowl H2O only to the extent that, in his sole opinion, the benefit of Prowl H2O 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 (including 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 H2O and contribute to poor stands because of 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 H2O may also cause injury to sensitive rotational crops. African Marigold Prowl H2O is only registered for use in African marigold grown for the purpose of lutein and zeaxanthin extraction. Prowl H2O may be applied by ground, chemigation, or on dry bulk fertilizer. Plant African marigold 1/4-inch to 3/4-inch deep and com- pletely cover with soil. Make sure that crop seeds are below the tilled soil surface area. Use Method, Rate, and Timing Prowl H2O may be applied in a single application or sequentially with an interval of 30 days or more. Uniformly apply Prowl H2O up to 4.2 pints per acre as a broadcast treatment before target-weed germination. Preplant Incorporated. Apply Prowl H2O within 60 days of planting and incorporate. Preemergence. Apply Prowl H2O at planting or up to 2 days after planting, but before crop emerges. Apply to a seedbed that is firm and free of clods. Postemergence. Apply Prowl H2O over-the-top postemergence after crop emergence for residual weed control. Postemergence-directed. Apply Prowl H2O as a postemergence-directed spray on the soil at the base of established plants, beneath plants, and between rows for residual weed control. Avoid direct contact with foliage or stems. Postemergence and postemergence-directed treatments are most effective in controlling weeds when adequate rainfall or overhead irrigation is received after application. If sufficient rainfall or irrigation does not occur to activate the herbicide, mechanically incorporate. Apply Prowl H2O before weeds germinate or after clean cultivation to remove existing weeds because Prowl H2O will not con- trol emerged weeds. Apply a postemergence herbicide to control emerged weeds. Crop-specific Restrictions • DO NOT apply more than 4.2 pints of Prowl H2O per acre in a single application. • DO NOT apply more than a maximum cumulative total of 8.4 pints of Prowl H2O per acre per year. • DO NOT graze livestock in treated fields or feed treated plant materials to animals. Crop-specific Precautions • Avoid overlapping spray patterns because crop injury can occur. • Avoid heavy residue on soil surface from previous year’s crops. • Avoid applying Prowl H2O to open furrows with exposed seed. Alfalfa (grown for Forage, Hay, or Seed) Prowl H2O may be applied by ground; air; chemigation; flood, flooded basin, and gravity flow irrigation systems; or on dry bulk fertilizer. Use Method, Rate, and Timing Established Alfalfa for Forage/Hay and Seed Production. Apply to estab lished alfalfa grown for forage or hay or seed production (defined as alfalfa planted in the fall or spring which has gone through a first cutting/ mowing). Apply in a single application or in sequential applications. Uniformly apply Prowl H2O at a broadcast rate of 1.1 to 4.2 quarts per acre before weed germination. Application can be made in the fall after the last cutting/ mowing, during winter dormancy, in the spring, or between cuttings. Apply before alfalfa reaches 6 inches in regrowth. Seedling Alfalfa. Apply to seedling alfalfa grown for for- age or hay or seed production (defined as alfalfa planted in the fall or spring which has NOT gone through a cutting/ mowing/seed harvest). Uniformly apply Prowl H2O at a broadcast rate of 1.1 to 2.1 pints per acre before weed ger- mination. Application can be made when seedling alfalfa has reached the second trifoliate growth stage. Apply before alfalfa reaches 6 inches in growth. Alfalfa Stand Establishment. Apply Prowl H2O at a broadcast rate of 1.0 to 1.5 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 H2O ; however, reduced weed com- petition will allow establishment of a quality stand. Use

16 lower rates on coarse-texture soil or in lower rainfall areas (receiving less than 20 inches of rainfall and irrigation a year). • Preplant Incorporated. Uniformly incorporate Prowl® H2O herbicide into the top 2 to 3 inches of the final seedbed before planting. • Preemergence. Apply directly after drill seeding alfalfa. Plant alfalfa into a seedbed that is firm and free of clods. Chemigation Application Prowl H2O may be applied through sprinkler irrigation systems. Follow all directions, special instructions, and restrictions about chemigation in the Application Instructions section of this label. Flood, Flooded Basin, and Gravity Flow Irrigation Systems Prowl H2O may be applied in flood, flooded basin, and gravity flow irrigation systems. Follow all directions, special instructions, and restrictions about flood, flooded basin, and gravity flow irrigation systems in the Application Instructions section of this label. Crop-specific Restrictions • DO NOT apply more than 4.2 quarts of Prowl H2O per acre between spring green-up and the last cutting/ mowing of the year. • DO NOT apply more than 4.2 quarts of Prowl H2O per acre in a single application. • For multiple applications, DO NOT apply more than a maximum cumulative total of 6.3 quarts of Prowl H2O per acre in any one year. [Alternate text: • Maximum cumulative total of 4.2 quarts of Prowl H2O per acre in any one year in California.] • Retreatment interval for sequential applications between the last cutting/mowing of the year and spring green-up of the following year - 28 days • Preharvest Interval (PHI) for the maximum dormant period application of 4.2 quarts per acre - 50 days • Preharvest Interval (PHI) for alfalfa forage and hay

• 14 days • Preharvest Interval (PHI) for alfalfa seed - 90 days Crop-specific Precautions • Some stunting and chlorosis of the alfalfa may occur with postemergence applications. • Application made after alfalfa exceeds 6 inches in height may result in poor weed control because of possible reduced spray coverage to the soil. Artichoke Prowl H2O may be applied by ground or air. Use Method, Rate, and Timing Prowl H2O must be applied pre-transplant, at least 1 to 2 days before transplanting artichoke. For a single applica - tion, uniformly apply Prowl H2O up to 3.0 pints per acre as a broadcast spray to the soil surface at least 60 days before harvest, or uniformly apply 3.1 to 8.2 pints per acre as a broadcast spray to the soil surface at least 200 days before harvest. Crop-specific Restrictions • DO NOT apply postemergence over the top of or to foli- age of artichoke because severe injury may occur. • DO NOT apply more than 3.0 pints per acre per year when using the 60-day preharvest interval. • If more than 3.0 pints per acre (up to 8.2 pints per acre) of Prowl H2O is applied, DO NOT harvest artichoke until 200 days after application. • DO NOT apply more than 8.2 pints per acre per year. • DO NOT feed forage or graze livestock in treated fields. Asparagus Prowl H2O may be applied by ground or air. Use Method, Rate, and Timing Apply Prowl H2O only to established asparagus or to newly planted crown asparagus. DO NOT apply to newly seeded asparagus. When applying to newly planted crown asparagus, assure crowns are fully covered with 2 to 4 inches of soil. With a single application, uniformly apply Prowl H2O to asparagus up to 8.2 pints per acre as a broadcast spray to the soil surface at least 14 days before the first spear har - vest or after seasonal harvest is complete. Application must be made before spear emergence or remove emerged spears before making the application. If aspara - gus is grown on sandy soils, DO NOT apply Prowl H2O at more than 2.4 pts/A. Crop-specific Restrictions • DO NOT apply postemergence over the top of emerged spears or severe injury may occur. • DO NOT apply more than 8.2 pints per acre per year. • Preharvest Interval (PHI) - 14 days • DO NOT feed forage or graze livestock in treated fields. • DO NOT apply by chemigation methods.

Corn (Field, Field Seed, Fresh Sweet, Popcorn, and Popcorn Seed) Prowl H2O may be applied by ground, air, chemigation, or on dry bulk fertilizer. Prowl H2O may be applied in conventional tillage, minimum tillage, or no-till as a preemergence, postemergence, or postemergence incor- porated ( CULTI-SPRAY) application in field corn. Prowl H2O may be applied in conventional tillage as a preemergence or postemergence application in field seed corn, popcorn, popcorn seed corn, and fresh sweet corn. 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 tillage provides good soil coverage of corn seed. In no-till systems, use a no-till planter capable of planting through crop residue. Use of no-till planters under condi- tions that do not allow good soil coverage of the corn seed can result in reduced crop stand or injury if Prowl H2O contacts the germinating corn seed. Check equipment to ensure good seed coverage. Additional Weeds Controlled. In addition to weeds list- ed in Table 2 , Prowl H2O controls the following weeds in corn with CULTI-SPRAY application: wild proso millet and shattercane. Use Method, Rate, and Timing Preemergence. Apply after planting but before weeds germinate and crop emerges. Postemergence. Apply postemergence until field corn is 30-inches tall (20-inches to 24-inches tall for popcorn, popcorn seed, field seed, and fresh sweet corn) or in the V8 growth stage, which ever is more restrictive. If the corn canopy prevents applications from reaching the soil, use drop nozzles and apply as a directed spray. CULTI-SPRAY. Apply Prowl H2O alone or Prowl H2O plus atrazine when field corn is at least 4-inches tall until last cultivation (layby). Prowl H2O plus atrazine must be applied before the field corn reaches 12 inches in height. See specific directions for (CULTI-SPRAY) application under Application Timings . DO NOT apply more than 1.2 lbs ai per acre of atrazine, as specified on the atrazine label. Under situations of low rainfall or soil moisture, when deep germi - nating weeds like shattercane or field sandbur are anticipated, mechanical incorporation provides the best results. If cultivation is needed after application and incorporation of Prowl H2O , the depth of cut should be no deeper than the depth of cut used to incorporate. Chemigation Application Prowl H2O may be applied through sprinkler irrigation systems. Follow all directions, special instructions, and restrictions about chemigation in the Application Instructions section of this label.

23 Additional Weeds Suppressed. In addition to weeds listed in Table 2 , Prowl® H2O herbicide will suppress Russian thistle in the state of Arizona. Use Method, Rate, and Timing Fall Application. Prowl H2O may be applied for weed control in cotton in the fall, after October 15 (up to 140 days before planting cotton) in Arizona, California, Louisiana, Mississippi, New Mexico, Oklahoma, and Texas. Apply Prowl H2O at the broadcast rate of 2.0 pints per acre on coarse or medium soils and 3.0 pints per acre on fine soils. Preplant Surface. Apply Prowl H2O within 15 days of planting. Preplant Incorporated. Apply Prowl H2O within 60 days of planting and incorporate. Preemergence. Apply Prowl H2O at planting or up to 2 days after planting. Apply to a seedbed that is firm and free of clods. Preplant Incorporated followed by Preemergence. Apply Prowl H2O within 60 days of planting and incorpo- rate. Apply overlay application of Prowl H2O at planting or up to 2 days after planting. Total amount of Prowl H2O applied per acre cannot exceed the highest labeled rate for a given soil type. Preplant incorporated and preemergence applications of Prowl H2O may be applied with the labeled tank mix herbicide(s). Layby Application (at last cultivation). Apply Prowl H2O directly to the soil between rows as a directed spray after the last normal cultivation (layby). Layby appli- cations can be applied in cotton previously treated with Prowl H2O or any herbicide(s) registered for use in cotton. The total amount of Prowl H2O applied per acre per year cannot exceed the highest labeled rate for a given soil type. Prowl H2O may also be applied at layby in cotton with herbicide-resistant traits. Postemergence. Prowl H2O may be applied by ground or air as a broadcast over-the-top postemergence applica- tion in cotton, including those varieties with a herbicide-resistant trait. Postemergence treatments are most effective in controlling weeds when adequate rainfall or overhead irrigation is received after application. Apply Prowl H2O before weeds germinate or after clean cultivation to remove existing weeds because Prowl H2O will not control emerged weeds. Apply a postemergence herbicide to control emerged weeds. Apply Prowl H2O broadcast postemergence (in water) over the top of cotton after cotton reaches the 4-leaf growth stage, but not after the 8-leaf growth stage. Over- the-top applications made before the 4-leaf growth stage or after the 8-leaf growth stage may result in crop injury and/or yield loss. Prowl H2O may also be tank mixed with herbicide prod- ucts registered for use on cotton varieties with a herbicide-resistant trait. When tank mixing Prowl H2O with another herbicide product, always follow the most restrictive labeling pertaining to application rates, methods, timings and precautions. DO NOT tank mix and apply over-the-top postemergence with fluometuron, gylphosate plus s-metolachlor, prometryn, or pyrithiobac-sodium, or s-metolachlor. Dry ammonium sulfate (AMS) at 17 lbs/100 gallons of spray solution must be used when tank mixing Prowl H2O with glyphosate-containing products. Liquid AMS may also be used, but must be used at an equivalent rate to 17 lbs of dry weight AMS/100 gallons of spray solution. A nitrogen replacement may not be used with this tank mix unless specified as acceptable from BASF in writing. An appropri - ate mixing order is as follows: fill tank to at least 1/2 full with water; then add in order: AMS, Prowl H2O , glyphosate; then fill the tank to capacity with water. Over-the-top postemergence application of Prowl H2O can be applied in cotton previously treated with at-planting soil applications of Prowl H2O or any other soil-applied herbicide(s) registered for use in cotton. Consult the labels of those herbicides for suggested treatments, rates, precautions, or restrictions for use in cotton, and for rota- tional crop restrictions. Follow the most restrictive label instructions when using products in combination with soil-applied Prowl H2O . Precautions: Postemergence application of Prowl H2O may cause temporary growth reduction and/or leaf dis - coloration or malformation of cotton after application. DO NOT apply over the top in fluid fertilizer. DO NOT apply in tank mix with any adjuvant, surfactant, oil, or other pesticide (except for cotton insecticides). DO NOT apply in any manner except as described in this label or crop injury and/or yield reduction may occur. DO NOT apply if cotton is under stress (including stress related to previous pesticide treatments, poor fertilization, environmental conditions, and/or pest damage) at time of application. If cotton is under stress (including stress relat - ed to previous pesticide treatments, poor fertilization, environmental conditions, and/or pest damage) at time of application, Prowl H2O may retard cotton recovery and/or adversely affect yield. Chemigation Application Prowl H2O may be applied through sprinkler irrigation systems. Follow all directions, special instructions, and restrictions about chemigation in the Application Instructions section of this label.

State-specific Instructions Idaho, Montana, North Dakota, Oregon, and Washington Prowl® H2O herbicide may be applied to chickpeas grown in no- tillage and/or minimum tillage systems in Idaho, Montana, North Dakota, Oregon, and Washington. Preplant surface applications must be made within 30 days of planting. DO NOT apply more than 1.5, 2.0, and 3.0 pts/A of Prowl H2O in coarse, medium, and fine texture soils, respectively. When planting, ensure the seed furrow is fully closed because conditions that allow the seed furrow to inadequately close and/or allow Prowl H2O to contact the seed may result in crop injury. Certain unfavorable environmental conditions, including cool temperatures, excessive moisture after application, and wet and/or compacted soil conditions, may result in delayed emergence and stunting with Prowl H2O use in chickpea. Adequate rainfall or irrigation after application before weed seedling germination provides the most effec - tive weed control. Herbicide performance from surface application may be decreased compared to soil incorpo - rated application. Idaho, Oregon, and Washington Prowl H2O may be applied postplant preemergence only to chickpea grown in conventional tillage systems in Idaho, Oregon, and Washington. Application must be made with- in 2 days of planting. Apply up to but not more than 1.5 pts/A. Apply to a firm seedbed free of clods. Soil con - ditions that cause poor seed furrow closure and coverage may result in delayed emergence and stunting of the crop. Under certain environmental conditions, including cool temperatures, excessive moisture after application and wet soil conditions may result in delayed emergence and stunt - ing with Prowl H2O use in chickpea. Adequate rainfall or irrigation after application before weed seedling germina - tion provides the most effective weed control. Colorado, Idaho, Kansas, Montana, Nebraska, New Mexico, Oregon, Washington, and Wyoming Apply Prowl H2O by ground postplant preemergence to dry beans grown under sprinkler irrigation in Colorado, Idaho, Kansas, Montana, Nebraska, New Mexico, Oregon, Washington, and Wyoming. Dry beans must have a minimum planting depth of 2 inches. Before applying Prowl H2O to dry beans, growers should check with their local seed company or seed supplier for sensitive varieties and to verify the selectivity of Prowl H2O on the grower’s specific dry bean variety. Prowl H2O application made postplant preemergence to dry beans must be immediate - ly followed by 0.50 to 0.75 inch of water from overhead irrigation/rainfall. Apply Prowl H2O within 1 to 4 days of planting and up to but not more than 2.0 pts/A. Apply to a firm seedbed free of clods. Soil conditions that cause poor seed furrow closure and coverage may result in delayed emergence and stunting of the crop. DO NOT apply as a chemigation application. DO NOT apply Prowl H2O in tank mix with halosulfuron or flumioxazin as a preemergence application to dry beans because of unac - ceptable crop response. Under certain environmental conditions, including cool temperatures, excessive mois - ture after application and wet soil conditions may result in crop injury, delayed emergence, and/or stunting with Prowl H2O use in dry beans. Adequate rainfall or irrigation after application before weed seedling germination pro - vides the most effective weed control. Crop-specific Restrictions • DO NOT feed lupin hay and forage or graze livestock in treated lupin fields. • DO NOT apply Prowl H2O more than once per year. • DO NOT apply in any type of irrigation system. Fallow Prowl H2O may be applied to fallow ground following crop harvest as a planned residual treatment to control labeled broadleaf and grass weeds as they germinate.

Certain environmental conditions including cool tem - peratures, excessive moisture after application, and wet soil conditions may result in delayed emergence and stunt - ing with Prowl H2O use in lentil or peas. Adequate rainfall or irrigation after application before weed seedling germi - nation provides the most effective weed control. Crop-specific Restrictions • DO NOT use in California. • DO NOT apply Prowl H2O preemergence in peas unless otherwise noted in state-specific instructions. • DO NOT apply Prowl H2O more than once per year. • DO NOT apply to lentil or peas, lentil or pea forage, pea silage, pea hay, or pea straw grown for livestock feed. • DO NOT apply in any type of irrigation system. Crop-specific Precautions • Any crop registered for a preplant incorporated applica - tion of Prowl H2O can be double cropped after peas. Melons Prowl H2O may be applied in the following melons: cantaloupe, citron melon, muskmelon, and watermelon. Prowl H2O may be applied only by ground. Use Method, Rate, and Timing Prowl H2O may be applied sequentially in melon produc - tion. Initially apply up to 2.1 pints per acre of Prowl H2O as a shielded application between rows with 6 inches on either side of row middles (before melon transplanting or before a seeded crop has emerged) or between rows cov - ered with plastic mulch (before holes are punched in plastic for melon planting). Make a second shielded appli - cation at up to 2.1 pints per acre of Prowl H2O between rows with a minimum of 6 inches on either side of stem or vines or between plastic mulch before melon vine running. The interval between the sequential Prowl H2O applica- tions must be at least 21 days. Avoid spray contact with melon foliage or running vines because crop injury will occur. Crop-specific Restrictions • DO NOT apply more than 2.1 pints per acre in a single application or more than 4.2 pints per acre per year. • Preharvest Interval (PHI) - 35 days • DO NOT feed forage or graze livestock in treated fields. • Not for use in California. Mint (Peppermint and Spearmint) Prowl H2O may be applied by ground or air. Use Method, Rate, and Timing Make a single broadcast preemergence application of Prowl H2O at 1.5 pints to 4.0 pints per acre, depending on soil texture (see chart following), to dormant established mint before weed germination. After Prowl H2O applica- tion, temporary crop injury may be observed early in the

32 growing season as mint breaks dormancy and begins to grow. Prowl® H2O herbicide will not cause crop injury when applied a ccording to the label under normal growing con - ditions. Nonuniform application may result in injury to crops, poor stands, or soil residues; conversely, uneven application may reduce weed control. Diseases, cold weather, excessive moisture, deep planting, low or high pH, salinity, or drought may weaken seedlings and plants and make them more susceptible to herbicide damage. Use Rate Soil Texture Broadcast Rate (pts/A) Coarse 1.5 to 2.0 Medium 2.0 to 4.0 Fine 2.0 to 4.0 Crop-specific Restrictions • DO NOT apply Prowl H2O to mint in the first year of growth and establishment. • DO NOT apply to mint that has broken dormancy or crop injury may result. Application to mint near dormancy break can result in crop injury. Risk of crop injury increases the closer application is to mint dormancy break. • DO NOT apply to mint stands that have been weakened by age, disease, cold weather, excessive moisture, or other factors that reduce crop vigor. Mint growing under stress is more susceptible to herbicide damage. • DO NOT apply more than 4.0 pints per acre per year. • Preharvest Interval (PHI) - 90 days • DO NOT allow livestock to graze on treated spent hay or feed treated spent hay to livestock. • DO NOT apply this product on mint through any type of irrigation system. Monarda Prowl H2O may be applied by ground, air, chemigation, or on dry bulk fertilizer. Use Method, Rate, and Timing Before weed germination, make a broadcast application of Prowl H2O at 1.5 pints to 4.0 pints per acre, depending on soil texture (see chart following), to established monar- da in dormancy, after emergence in the spring, or after the first harvest. After Prowl H2O herbicide application, tem- porary crop injury may be observed during the growing season as monarda breaks dormancy and begins to grow, or re-grows after harvest. Prowl H2O will not cause crop injury when applied according to the label under normal growing conditions. Nonuniform application may result in injury to crops, poor stands, or soil residues; conversely, uneven application may reduce weed control. Diseases, cold weather, exces- sive moisture, deep planting, low or high pH, salinity, or drought may weaken seedlings and plants and make them more susceptible to herbicide damage. Use Rate Soil Texture Broadcast Rate (pts/A) Coarse 1.5 to 2.0 Medium 2.0 to 4.0 Fine 2.0 to 4.0 Chemigation Applications Prowl H2O may be applied through sprinkler irrigation systems. Follow all directions, special instructions, and precautions about chemigation in the Application Instructions section of this label. Crop-specific Restrictions • DO NOT apply Prowl H2O to monarda in the first year of growth until transplants are well established. • DO NOT apply to monarda stand that have been weak- ened by age, disease, cold weather, excessive moisture, or other factors that reduce crop vigor, as monarda growing under stress is more susceptible to herbicide damage. • DO NOT apply more than 4.0 pts (1.9 lbs of pendimethalin) of Prowl H2O per acre per year. • Preharvest Interval (PHI) – 90 days • DO NOT allow livestock to graze on treated spent hay or feed treated spent hay to livestock. Crop-specific Precautions • A void overlapping spray patterns because crop injury can occur. • A void heavy residue on soil surface from previous year’s crops. Peanut Prowl H2O may be applied by ground, air, chemigation, or on dry bulk fertilizer (only fall and preplant incorporated applications). DO NOT use in California. Use Method, Rate, and Timing Preplant Incorporated. Apply Prowl H2O up to 60 days before planting and incorporate. Preemergence. Apply Prowl H2O at planting or up to 2 days after planting and before crop emergence. For pea - nuts grown under overhead irrigation or to prevent decreased crop pegging, adequate incorporation must be achieved by applying a minimum of 0.75 inch of overhead irrigation or rainfall within 48 hours after Prowl H2O application. Chemigation Application Prowl H2O may be applied through sprinkler irrigation systems. Follow all directions, special instructions, and restrictions about chemigation in the Application Instructions section of this label.

• For heavy weed infestations, especially of Texas panicum, up to 3.2 pts/A of Prowl® H2O herbicide can be used in Alabama, Florida, or Georgia. Perennial Grasses Grown for Seed Production Prowl H2O may be applied to established (defined as planted in the fall or spring which has gone through a first cutting/mowing) warm-season perennial grasses (including Bermudagrass, switchgrass, and others) and to estab- lished (6 or more tillers per plant) cool-season perennial grasses (including Kentucky bluegrass, tall fescue, orchardgrass, perennial ryegrass, fine fescue, and others). Prowl H2O may be applied by ground, chemigation, air, or on dry bulk fertilizer. Use Method, Rate, and Timing In warm-season perennial grasses, apply Prowl H2O to postharvest grass during the fall or during winter dorman - cy or after the first seed harvest/cutting. DO NOT apply to warm-season perennial grasses after greenup in the spring before the first seed harvest/cutting. In cool-season peren - nial grasses, apply Prowl H2O to postharvest grass during regrowth at the beginning of significant fall rains or in spring. Apply Prowl H2O before target-weed germination. Uni- formly apply at a broadcast rate of 2.1 to 4.2 quarts of Prowl H2O per acre in a single application. Prowl H2O may also be applied in two split applications, with 1/2 the annual application rate applied in fall or winter followed by the remaining 1/2 of the annual application rate applied in spring. DO NOT apply more than a maximum cumulative total of 4.2 quarts of Prowl H2O per acre in any one year. In warm-season and cool-season perennial grasses, use the high application rate of Prowl H2O where more dense infestations of targeted annual grasses, annual broadleaf weeds, or volunteer grass seedlings are anti cipated, or when a longer duration of residual weed control is desired. Excess grass straw and crop residue from the previous harvest must be evenly spread or removed by such meth - ods as crew cutting, propane flaming, or open field burning (when local regulations allow) before Prowl H2O application, or reduced weed control may result. Prowl H2O may be applied in a sequential use program or as a tank mix with other registered herbicides that control emerged weeds. Prowl H2O may cause temporary injury to perennial grass stands. Application made in periods of cold temperatures that temporarily limit normal crop growth or in extended cold temperature periods that initiate winter dormancy in grass crops may result in crop injury. Diseases, extremely cold weather, drought, extensive frost heaving, low or high pH, or salinity may weaken stands and make them more susceptible to herbicide damage. Chemigation Application Prowl H2O may be applied through sprinkler irrigation systems. Follow all directions, special instructions, and restrictions about chemigation in Application Instructions section of this label. Additional Weeds Controlled Prowl H2O applied before weed germination controls annual bluegrass, volunteer fescue, and volunteer ryegrass in addition to weeds listed in Table 2 . Tank Mixes Prowl H2O may be tank mixed with Outlook® herbicide (dimethenamid-p) or with other herbicides labeled for use in perennial grasses grown for seed. BASF recommends testing Prowl H2O tank mixes on a small portion of the target crop to determine if damage is likely to occur. Physical incompatibility, reduced weed control, or crop injury may result from mixing Prowl H2O with other pesticides, additives, or ferti lizers. Application of postemergence herbicides may cause crop injury. Consult your local BASF dealer regarding local tank mix options. Always perform a mixing test to check the compatibility of Prowl H2O with all potential tank mix part- ners. Follow all precautions and restrictions on the labels of all products applied in combination with Prowl H2O . Always follow the most restrictive label. Crop-specific Restrictions • DO NOT apply if surface water is present in the field. • DO NOT apply more than a maximum cumulative total of 4.2 quarts of Prowl H2O per acre in any one year. • There is no preharvest interval for grass forage or hay, or for livestock grazing after application of Prowl H2O • Preharvest Interval (PHI) for seed of warm-season and cool-season perennial grasses - 90 days • Not for use in California except as directed in supple- mental labeling. Crop-specific Precautions • Some stunting and chlorosis of perennial grasses may occur with postemergence application. • Application made after perennial grasses exceed 6 inches in height may result in poor weed control because of possible reduced spray coverage to the soil. • Grass straw remaining after seed harvest of warm-season and cool-season perennial grasses may be used as livestock bedding, and/or grazed by or fed to livestock. The grower must notify the seed processor that there is no pesticide tolerance on grass seed screenings; therefore, it cannot be used in livestock feed.

34 Potato Prowl® H2O herbicide may be applied by ground, air, chemigation, or on dry bulk fertilizer (preemergence incor - porated only). Additional Weeds Controlled. In addition to the weeds listed in Table 2 , Prowl H2O controls stinging nettle in potatoes. Use Method, Rate, and Timing Preemergence. Apply Prowl H2O after planting, but before potatoes and weeds emerge, or after dragoff. Preemergence Incorporated. Apply Prowl H2O and incorporate after planting but before potatoes and weeds emerge. Where dragoff is practiced, apply Prowl H2O and incorporate before, at, or after dragoff, but before potatoes and weeds emerge. Take care incorporation equipment does not damage seed pieces or elongating sprouts. Early Postemergence. Apply Prowl H2O from crop emergence to the 6-inch growth stage. DO NOT apply Prowl H2O postemergence if potatoes are under stress from cold/wet or hot/dry conditions or crop injury may occur. Chemigation Application Prowl H2O may be applied through sprinkler irrigation systems. Apply Prowl H2O preemergence after planting, after dragoff, or early postemergence through sprinkler irri - gation systems. Follow all directions, special instructions, and restrictions about chemigation in the Application Instructions section of this label. Use Rate Soil Texture < 3% Organic Matter > 3% (pts/A) Coarse 1.5 1.5 Medium 2.0 3.0 Fine 3.0 3.0 Crop-specific Restrictions • DO NOT apply to sweet potatoes or yams. • DO NOT apply preplant. • DO NOT make more than one application of Prowl H2O per year. Crop-specific Precautions • Application of Prowl H2O on White Rose variety potatoes during or followed by cool and/or wet weather conditions may result in crop injury. Rice Prowl H2O may be applied by ground, air, or on dry bulk fertilizer (delayed preemergence and early postemergence applications only) to rice grown under conventional-tillage, reduced-tillage, minimum-tillage, or no-till systems, or on stale seedbeds. Additional Weeds Controlled. In addition to weeds list- ed in Table 2 , Prowl H2O controls the following weeds in rice: junglerice and sprangletop. Use Method, Rate, and Timing Delayed Preemergence. Apply Prowl H2O alone or with tank mix partner for delayed preemergence weed control in grain-drilled, dry-seeded rice. Apply Prowl H2O alone or in tank mix to levees after the levees are pulled and planted. The seedbed needs to be firm and free of clods and must be prepared to allow for good seed cover- age. Use of a planter under conditions that do not allow good soil coverage of the rice seed can result in reduced stand or stunting if Prowl H2O contacts germinating rice seed. Exposed seeds that come in contact with Prowl H2O may be injured. Apply only when growing con- ditions favor vigorous rice growth. The seedbed should have adequate moisture for seed germination. Not for use in grain-drilled, dry-seeded rice in California. Uniformly apply the specified rate of Prowl H2O after rice planting and before rice emergence (spiking) and weed germination. Apply after 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, BASF recommends flushing before Prowl H2O application to supply moisture for root (radicle) initiation and for vigorous rice and weed growth. If applied to soil before 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. Because of the residual activity of Prowl H2O , 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 H2O . Early Postemergence. Apply Prowl H2O as a tank mix partner in dry-seeded rice. 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 before treatment to produce vigorous rice and weed growth. Because soil and weeds must be complete - ly exposed to spray coverage, no flood water should be on the field at the time of application. Cloddy soil, standing water (puddles) at the time of application, or cracks in the soil that form after application may result in reduced weed

35 control. Because of residual activity of Prowl® H2O herbicide, this treatment may be applied if rice is too small to maintain a flood on the field for weed control. However, proper water management practices must be followed for normal rice growth and activity of Prowl H2O . Postemergence (California water-seeded rice only). As a component of a comprehensive weed management program, apply Prowl H2O alone or tank mixed with a postemergence herbicide after water-seeded rice has reached the 4-leaf to 6-leaf stage (spike plus 3 to 5 true leaves). Applications made before the 4-leaf rice stage may result in crop injury. Water-seeded rice must also be well-rooted/pegged (i.e. standing erect after the flood is removed) before appli - cation. DO NOT apply to rice that is leaning over and/or laying flat to the ground after flood removal since this is characteristic of a poorly established root system. Rice roots must be below the Prowl H2O -treated soil zone. Injury, stunting, and/or stand reduction can occur if Prowl H2O contacts the rice roots. Fields must be completely drained and free of standing water (moist/saturated soil) before application. If soil is saturated at the time of application, allow the soil surface to dry before restoring the permanent flood. Prowl H2O requires alternate wetting/drying cycles to be activated. Weed control will be reduced if the soil surface is not allowed to dry out before restoration of the permanent flood. Resume normal water management practices after permanent flood restoration. Prowl H2O does not control weeds postemergence; therefore, Prowl H2O must be tank mixed with a postemergence herbicide to control emerged weeds at the time of application. Prowl H2O aids in control or suppression of the following weeds when used as part of a comprehensive weed man - agement program: Barnyardgrass, early and late watergrass (including bio - types resistant to other herbicide modes of action, e.g. rice mimic), sprangletop, smallflower umbrella sedge*, redstem*

• Suppression only In California water-seeded rice, Prowl H2O may be applied with aerial or ground application equipment. For aerial application, apply the specified rate of Prowl H2O in 5 gallons to 10 gallons of water per acre. If applied as a tank mix with another herbicide, make sure proper gal - lonage per acre per label directions (i.e. 10 to 15 with propanil) is used to ensure thorough coverage. To minimize drift, DO NOT apply during periods of wind more than 10 mph, or when wind conditions favor drifting, or if there is a temperature inversion. BASF recommends that a flag- man or an automatic mechanical flagging unit on the aircraft be used to avoid overlapping and possible crop injury. For ground equipment, apply the specified rate of Prowl H2O in 10 gallons to 20 gallons of water per acre. If Prowl H2O is applied as a tank mix with another herbicide, make sure proper gallonage per acre per label directions (i.e. 20 to 30 for propanil) is used to ensure thor- ough coverage. Use a calibrated low-pressure (20 PSI to 40 PSI) sprayer equipped with appropriate nozzles for uni - form spray distribution and minimize drift. Keep the bypass line on or near the bottom of the tank to minimize foaming. Nozzle screens must be no finer than 50 mesh. DO NOT apply Prowl H2O during periods of gusty winds or when wind velocity is more than 20 mph. Postemergence Tank Mixes: To control emerged weeds at application, Prowl H2O may be tank mixed with one of the following postemergence herbicides: bispyribac-sodium cyhalofop orthosulfamuron penoxsulam propanil triclopyr When using tank mixes with Prowl H2O , always read the companion product label(s) and follow all precautions and restrictions. Always follow the most restrictive label. Observe all restrictions regarding propanil-restricted zones. Crop-specific Restrictions (for water-seeded rice) • DO NOT apply Prowl H2O before the 4-leaf rice stage (spike plus 3 true leaves) or to rice that is not well-rooted/ pegged. The rice must be standing erect after the flood is removed and before application. • DO NOT apply to fields with standing water. • DO NOT apply Prowl H2O through any type of irrigation system. • DO NOT apply in liquid fertilizer. • DO NOT spray target crop within 60 feet of sensitive crops (crops not listed on the Prowl H2O label). • DO NOT spray target crop within 60 feet of crops labeled for Prowl H2O application where the method of application, rate, or timing of spray application is prohibited. • DO NOT apply more than the maximum rate for any soil type in one year. • DO NOT use water containing Prowl H2O residues from rice cultivation to irrigate food or feed crops not reg- istered for use with Prowl H2O . In case of a crop failure because of weather conditions or disease after treatment with Prowl H2O alone or in tank mix, only drilled dry-seeded rice may be immediately replanted; however, the grower assumes all risks and con- sequences associated with replanting of rice because there is the potential for stand reduction or stunting. BASF recommends a 10% increase in seeding rate. Replant seed below the herbicide layer because reduced stand or stunting may occur if Prowl H2O contacts germinating rice seed. DO NOT replant gibberellic acid-treated seed. DO NOT reapply Prowl H2O alone or in tank mix. DO NOT apply to stressed rice.

BASF recommends a 10% increase in seeding rate. Replant seed below the herbicide layer because reduced stand or stunting may occur if Prowl H2O con- tacts germinating rice seed. DO NOT replant with gibberellic acid-treated seed. DO NOT reapply Prowl H2O alone or in tank mix. • DO NOT apply Prowl H2O 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 or preplant incorpo - rated because severe rice injury is possible. Rosemary Prowl H2O may be applied by ground, air, chemigation, or on dry bulk fertilizer. Use Method, Rate, and Timing Before weed germination, make a broadcast application of Prowl H2O at 1.5 pints to 4.0 pints per acre, depending on soil texture (see chart following), to established rose- mary prior to onset of rapid growth in early spring or after the first harvest. After Prowl H2O herbicide application, temporary crop injury may be observed during the growing season as rosemary grows or re-grows after harvest. Prowl H2O will not cause crop injury when applied according to the label under normal growing conditions. Nonuniform application may result in injury to crops, poor stands, or soil residues; conversely, uneven application may reduce weed control. Diseases, cold weather, exces- sive moisture, deep planting, low or high pH, salinity, or drought may weaken seedlings and plants and make them more susceptible to herbicide damage. Use Rate Soil Texture Broadcast Rate (pts/A) Coarse 1.5 to 2.0 Medium 2.0 to 4.0 Fine 2.0 to 4.0 Chemigation Applications Prowl H2O may be applied through sprinkler irrigation systems. Follow all directions, special instructions, and precautions about chemigation in the Application Instructions section of this label. Crop-specific Restrictions • DO NOT apply Prowl H2O to rosemary in the first year of growth and establishment. • DO NOT apply to rosemary stand that have been weak- ened by age, disease, cold weather, excessive moisture, or other factors that reduce crop vigor, as rosemary growing under stress is more susceptible to herbicide damage. • DO NOT apply more than 4.0 pts (1.9 lbs pendimethalin) of Prowl H2O per acre per year. • Preharvest Interval (PHI) – 60 days • DO NOT allow livestock to graze on treated spent hay or feed treated spent hay to livestock. Crop-specific Precautions • Avoid overlapping spray patterns because crop injury can occur.

37 • Avoid heavy residue on soil surface from previous year’s crops. Safflower Prowl® H2O herbicide may be applied to safflower by ground, air, or on dry bulk fertilizer (only fall and preplant incorporated applications). Plant safflower 1-1/2 inches to 2-inches deep and completely cover with soil. In California, plant safflower deep enough to completely cover with soil. Use Method, Rate, and Timing Preplant Incorporated. In all states, apply within 60 days of planting and incorporate. Preplant Incorporated Fall Application in Minnesota, Montana, North Dakota, and South Dakota. Apply Prowl H2O and immediately incorporate in late fall before planting safflower the following spring. Apply Prowl H2O in the late fall when soil temperatures are 45° F or below but before the ground freezes. DO NOT apply when air temperature is below 45º F. Before safflower planting in the spring, fields treated with Prowl H2O must receive at least one shallow addi- tional incorporation. Spring incorporation must be at an angle to the last tillage operation. Fall Application in California. Apply Prowl H2O and immediately incorporate during tillage operations in the fall to target winter annual weeds before planting safflower the following spring. Before safflower planting in the spring, fields treated with Prowl H2O must receive at least one additional incorporation. Preemergence. Apply Prowl H2O at planting or up to 2 days after planting. Preemergence application of Prowl H2O to safflower may increase the likelihood of crop injury, especially when crops are grown in stress situations, including compacted soils. Decreased herbicide performance compared to pre - plant incorporated application may also result from a preemergence application. If dry conditions with limited precipitation exist or unseasonably cool temperatures after planting are forecast, apply Prowl H2O before planting and mechanically incorporate with tillage. Prowl H2O may be applied preemergence in conventional- tillage safflower. Preemergence application of Prowl H2O to safflower grown in California must be followed with irrigation or rain - fall to establish a crop stand. No-till Safflower.

Strawberry (and other Low-growing Berries) Prowl H2O may be applied in the following low-growing berries: Bearberry Bilberry Blueberry, lowbush Cloudberry Cranberry Lingonberry Muntries Partridgeberry Strawberry Prowl H2O may be applied by ground, air, or chemigation. Use Method, Rate, and Timing Stunting, reduced growth, or reduction in daughter plants may occur with use of Prowl H2O in strawberries and other low-growing berries. Uniformly apply 1.5 to 3.0 pints per acre of Prowl H2O as a broadcast spray to the soil surface at pretransplant time or post-transplant time (must be within 7 days of trans- planting of rootstock in the Pacific Northwest). However, in areas where irrigation is used daily (frequently) after trans - planting, apply Prowl H2O just before the end of the watering regime to maximize weed control benefits of Prowl H2O . Extended periods of irrigation may reduce residual control provided by Prowl H2O . However, Prowl H2O applications to row middles between the beds are allowed. DO NOT apply post- transplant if new foliage from rootstock is exposed to spray area. A second application of 1.5 to 3.0 pints per acre of Prowl H2O may be applied in a band to the soil between crop rows (or between the plastic beds) 35 days before harvest, but DO NOT CONCENTRATE THE RATE per acre into the treated area, and DO NOT allow spray to contact strawberry or other low-growing berry plants. The second application rate is based on per unit of treated area. Prowl H2O may also be applied to strawberries or other low-growing berries in fall or winter dormancy.
