General Notice 1
Mode of Action Pendimethalin, the active ingredient in Prowl H2O, is a Group 3 (WSSA)/Group K1 (HRAC) herbicide belonging to the dinitroaniline chemistry class. 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 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 H2O or other Group 3 herbicides. To delay herbicide resistance consider: - Avoiding the consecutive use of Prowl H2O or other target 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 different target-site-of-action groups as long as the involved products are all registered for the same use, have different 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 cultural and mechanical methods. - Monitoring treated weed populations for loss of field efficacy, 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 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 identified 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 particular 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 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 3 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 3. Soil Texture Groups See table on page 6 of Master Label * 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 inconsistent and/or reduced. Use maximum labeled use rate allowed in the specific crop.

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 chemigation to crops unless specified in Crop-specific Information section. Apply this product ONLY through a sprinkler irrigation system 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(R) H2O 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. If you have any questions about calibration, contact State Extension Service specialists, 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 uniform 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 should run a sufficient amount of time before Prowl H2O injection to have all emitters functioning 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 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/43,560 x R = qts of Prowl H2O 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 300/144 and B = 1105.6 square feet wetted per acre If the system covers 20 acres, then C = 1105.6 square feet per acre x 20 acres and C= 22,112 square feet wetted by system If the desired application rate per treated acre is 2.0 qts of Prowl H2O, then S = 22,112/43,560 x 2.0 and S = 1.0 qt = amount of Prowl H2O to inject 43,560 into the system 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 functional, 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 functional 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 functional 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 pesticide distribution is adversely affected. 8. The irrigation line or water pump must include a functional 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 systems must contain a functional, reduced-pressure zone backflow preventer (RPZ) or the functional equivalent in the water supply line upstream from the point of pesticide 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 reservoir tank of at least twice the inside diameter of the fill pipe. 3. All chemigation systems connected to public water systems must also follow restrictions listed in the preceding sections involving Chemigation.

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/43,560 x R = qts of Prowl H2O 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 300/144 and B = 1105.6 square feet wetted per acre If the system covers 20 acres, then C = 1105.6 square feet per acre x 20 acres and C= 22,112 square feet wetted by system If the desired application rate per treated acre is 2.0 qts of Prowl H2O, then S = 22,112/43,560 x 2.0 and S = 1.0 qt = amount of Prowl H2O to inject 43,560 into the system 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 functional, 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 functional 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 functional 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 pesticide distribution is adversely affected. 8. The irrigation line or water pump must include a functional 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 systems must contain a functional, reduced-pressure zone backflow preventer (RPZ) or the functional equivalent in the water supply line upstream from the point of pesticide 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 reservoir tank of at least twice the inside diameter of the fill pipe. 3. All chemigation systems connected to public water systems must also follow restrictions listed in the preceding sections involving Chemigation.

Application via Flood, Flooded Basin, or Gravity Flow Irrigation Systems Prowl(R) H2O herbicide 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 olive trees, bearing and nonbearing vineyards, bearing and nonbearing small fruit climbing vines, nonbearing date palm, and nonbearing fig trees. Use Instructions and Restrictions for Flood, Flooded Basin, and Gravity Flow Irrigation 1. Prowl H2O may be applied through flood, flooded basin, or gravity flow irrigation systems designed to uniformly distribute irrigation water along the soil surface. Solid set systems using tall riser for overhead application are excluded. 2. Follow all label directions for Prowl H2O regarding rates per acre, timing of application, and crop-specific restrictions and precautions. 3. 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. 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 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. 6. Systems using a gravity-flow pesticide dispensing system must meter the pesticide in the water at the head of the field downstream of a hydraulic discontinuity, including 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 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 injection system must meet the following requirements: - The system must contain a functional check valve, vacuum relief valve, and low-pressure drain appropriately located in the irrigation pipe to prevent water source contamination from backflow. - The pesticide injection pipeline must contain a functional, 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 injection 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 materials that are compatible with pesticides and capable of being fitted with a system interlock. - Any alternative to the above safety devices must conform 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 effectiveness, or illegal pesticide residues in the crop. 11. For questions about calibration, contact State Extension 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 environmental 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 recommended 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 recommendations 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. 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. Temperature inversions are characterized by increasing temperature with altitude and are common on nights with limited cloud cover and light to no wind. The presence of an inversion can be indicated by ground fog or by the movement of smoke from a ground source or an aircraft smoke generator. Smoke that layers and moves laterally in a concentrated cloud (under low wind conditions) indicates an inversion, while smoke that moves upward and rapidly dissipates indicates good vertical air mixing. Avoid applications during temperature inversions. 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.

Rotational Crop Restrictions - Use of Prowl H2O in accordance with label directions is expected to result in normal growth of rotational crops in most situations; however, various environmental and agronomic factors, including 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 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 combinations, 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 rotational 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 determine 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, 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, or grapes) for 24 months after Prowl H2O application.

Tank Mix Information
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 liquid (L) formulation (depending on mixing ratio required) to the liquid fertilizer. To calculate teaspoons of the formulation to add: lbs or pts of product/acre/gallons of fertilizer/acre x 11.4 = teaspoons of herbicide to add to 1 pint of fertilizer 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 chemicals 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 shaking, 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 teaspoon 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(R) H2O herbicide with that specific liquid fertilizer.
