Use Information Pendimethalin 3.3 EC is a selective herbicide for controlling most annual grasses and certain broadleaf weeds as they germinate. Refer to Table 1 for a complete list of controlled weeds. Pendimethalin 3.3 EC will not control established weeds.

FOR USE IN ALFALFA, BEARING CITRUS FRUIT TREES, BEARING NUT TREES, BEARING POME FRUIT TREES, BEARING STONE FRUIT TREES, CARROTS, CO RN (FIELD, POP, SEED, SWEET), COTTON, EDIBLE BEANS, FORAGE LEGUMES, FRUITING VEGETABLES (PEPPER, TOMATO), GARLIC, GRAIN SORGHUM, LEEK, LENTILS AND PEAS, MINT, NONBEARING FRUI T TREE AND NUT TREE CROPS, NONBEARING VINE- YARDS, ONIONS AND SHALLOTS (DRY BULB, GREEN), PEANUTS, POTATOES, RICE, SOYBEANS, STRAW- BERRY, SUGARCANE, SUNFLOWERS, TOBACCO, AND WHEAT.

Unusually cold, excessively wet, or hot and dry conditions that delay germination or extend germination over a long period of time can reduce weed control. Overapplications can result in crop stand loss, crop injury, or soil residues. Uneven application or improper soil incorporation can decrease weed control or cause crop injury. Soil incorpora- tion deeper than directed can reduce weed control. Seedling diseases, cold weather, excessive moisture, shallow or deep planting, low or high soil pH, high soil salt concentration, or drought can weaken seedlings and plants and increase the possibility of crop damage from Pendimethalin 3.3 EC. Under these conditions, crop yields can be reduced

Mode of Action Pendimethalin 3.3 EC is a meristematic inhibitor that interferes with the plant's cellular division or mitosis.

Weed Resistance Management For resistance management, Pendimethalin 3.3 EC is a Group 3 herbicide. Any weed population may contain or develop plants naturally resistant to Pendimethalin 3.3 EC and other Group 3 herbicides. The resistant biotypes may dominate the weed population if these herbicides are used repeatedly in the same field. Appropriate resistance management strategies should be followed.

To delay herbicide resistance, take one or more of the following steps: x Rotate the use of Pendimethalin 3.3 EC or other Group 3 herbicides within a growing season sequence or among growing seasons with different herbicide groups that control the same weeds in a field. x Use tank mixtures with herbicides from a different group if such use is permitted; where information on resistance in target weed species is available, use the less resistance-prone partner at a rate that will control the target weed(s) equally as well as the more resistance-prone partner. Consult your local extension service or certified crop advisor if you are unsure as to which active ingredient is currently less prone to resistance. x Adopt an integrated weed-management program for herbicide use that includes scouting and uses historical information related to herbicide use and crop rotation, and that considers tillage (or other mechanical control methods), cultural (e.g., higher crop seeding rates; precision fertilizer application method and timing to favor the crop and not the weeds), biological (weed-competitive crops or varieties) and other management practices. x Fields should be scouted prior to application to identify the weed species present and their growth stage to determine if the intended application will be effective. x Scout after herbicide application to monitor weed populations for early signs of resistance development. Indicators of possible herbicide resistance include:

  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;
  3. Surviving plants mixed with controlled individuals of the same species. If resistance is suspected, prevent weed seed production in the affected area by an alternative herbicide from a different group or by a mechanical method such as hoeing or tillage. Prevent movement of resistant weed seeds to other fields by cleaning harvesting and tillage equipment when moving between fields and planting clean seed. x If a weed pest population continues to progress after treatment with this product, discontinue use of this product, and switch to another management strategy or herbicide with a different mode of action, if available. x Contact your local extension specialist, certified crop advisors, and/or Winfield Solutions, LLC representative for pesticide resistance management and/or integrated weed management recommendations for specific crops and resistant weed biotypes. x For further information or to report suspected resistance, contact your Winfield Solutions, LLC representative.

Application Rate Use rates for Pendimethalin 3.3 EC when used alone, in tank mix, or sequential applications are given in the Crop- specific Information section of this label. Use rates of this product vary by soil texture and organic matter. See Table 2 for soil texture groupings used in this label.

Table 2. Soil Texture Groups COARSE MEDIUM FINE sands sandy clay loams* silty clay loams* loamy sands sand y clays silt y clays sandy loams loams clay loams silt loams clays silts

*Sometimes considered transitional soils and may be classified as either medium- or fine-textured soils. Peat and Muck soils: Pendimethalin 3.3 EC 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.

Application Timings Pendimethalin 3.3 EC will provide most effective weed control when applied by ground or aerial equipment and subsequently incorporated into soil within 7 days after application by rainfall, sprinkler irrigation, or mechanical tillage prior to weed seedling emergence from soil. Pendimethalin 3.3 EC can also be applied through chemigation, including flooded basin irrigation systems. Pendimethalin 3.3 EC is labeled for preplant surface, preplant incorporated, surface incorporated, preemergence, early postemergence, postemergence incorporated (CULTI-SPRAY) or layby treatment. See the Crop-specific Information section of this label for application directions by crop.

Preplant Surface Applications: For use in minimum tillage or no-tillage production systems, apply Pendimethalin 3.3 EC alone or in tank mixes up to 45 days before planting. When making early preplant surface applications (15 to 45 days prior to planting), tank mix Pendimethalin 3.3 EC or follow with a postemergence herbicide application. Rainfall or sprinkler irrigation within 7 days after application is required to move this product into the upper soil surface where weed seeds germinate.

Preplant Incorporated Applications: Apply Pendimethalin 3.3 EC and incorporate into the upper (1 inch to 2 inches) soil surface up to 60 days before planting. Use an implement capable of giving uniform incorporation; two-pass incorporation usually results in a more consistent result.

Surface Incorporated Applications: Uniformly apply Pendimethalin 3.3 EC as broadcast or banded treatment to soil surface underneath established trees and/or in ground areas between trees rows. Within 7 days after application, incorporate into upper (1 inch to 2 inches) soil surface using either rainfall, sprinkler irrigation, or shallow mechanical incorporation using an implement capable of giving uniform incorporation; two-pass mechanical incorporation usually results in a more consistent result.

Preemergence Surface Applications: Broadcast treatment uniformly to the soil surface at planting and up to 2 days after planting. Rainfall, sprinkler irrigation, or shallow mechanical incorporation within 7 days after application is required to move this product into the upper soil surface where weed seeds germinate. If adequate rainfall or irrigation does not occur and weed seedling emergence begins, a shallow cultivation or rotary hoeing will improve performance.

Early Postemergence Applications: Pendimethalin 3.3 EC must be applied prior to weed seedling emergence or in a tank mix with products that control the emerged weeds. Refer to the Crop-specific Information section of this label for specific postemergence application instructions by crop.

Postemergence Incorporated Applications (CULTI-SPRAY): Prior to application, the crop must be cultivated in such a manner as to throw at least one inch of soil over the base of the crop plants. This will prevent direct contact of Pendimethalin 3.3 EC and the zone of brace root formation. Pendimethalin 3.3 EC must be applied broadcast with a ground sprayer when crop is at least 4 inches tall up to layby. Use drop nozzles if crop foliage will prevent uniform coverage of the soil surface within the rows. Thoroughly and uniformly incorporate Pendimethalin 3.3 EC treatments into the soil with: (1) a sweep-type or rolling cultivator set to provide thorough incorporation in the top 1 inch of soil, or (2) adequate overhead irrigation water or rainfall. See the Crop-specific Information (Corn and Grain Sorghum) section of this label for more details on (CULTI-SPRAY) application.

Layby Application: Apply Pendimethalin 3.3 EC directly to the soil between rows as a directed spray following the last normal cultivation (layby). See the Crop-specific Information section of this label for more details on layby application.

Split Applications: Pendimethalin 3.3 EC may be applied pre-plant incorporated up to 60 days prior to planting and followed by a preemergence application at planting or up to 2 days after planting. The total amount of Pendimethalin 3.3 EC applied per acre per season cannot exceed the highest labeled rate for any given soil type. See the Crop- specific Information section of this label for more details on split applications.

Fall Applications: Pe ndimethalin 3.3 EC may be used in fall application programs in certain crops. See the Crop- specific Information section of this label for details on fall application timing.

Spraying Instructions Pendimethalin 3.3 EC may be applied using either water or sprayable fluid fertilizer (such as straight 32-0-0 or 28-0- 0) as the spray carrier. Additionally, Pendimethalin 3.3 EC may be impregnated on dry bulk fertilizer. Sprayable fluid fertilizer as a carrier is NOT labeled for use after crop emergence unless the typical fertilizer burn symptoms on the crop are acceptable. Aerial Applications Uniformly apply in 5 or more gallons of water per acre. Exercise caution to minimize drift. Spray drift can cause injury to sensitive crops. See the Spray Drift Management section of this label for spray drift mitigation measures. Use a flagman or an automatic mechanical flagging unit on the aircraft to avoid overlapping and possible crop injury. Ground Applications (Broadcast) Uniformly apply with properly calibrated ground equipment in 10 or more gallons of water per acre or 20 or more gal- lons of liquid fertilizer per acre. Use sprayers equipped with appropriate nozzles that provide uniform and accurate spray distribution and minimize drift. See the Spray Drift Management section of this label for spray drift mitigation measures. 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. Application of Pendimethalin 3.3 EC during periods of gusty winds may result in uneven applications. DO NOT apply Pendimethalin 3.3 EC postemergence in liquid fertilizers. If liquid fertilizer/herbicide(s) mixture separates in the spray tank, clogged equipment and uneven application can result. Always predetermine the compatibility of Pendimethalin 3.3 EC alone or with other herbicides based on the following compatibility "jar test":

  1. Add 1 pint of fertilizer to a quart jar.
  2. Add 1 to 4 teaspoon(s) of the Dry Flowable (DF), Wettable Powder (WP), Aqueous Solution (AS), Flowable (F) or Liquid (L) formulation (depending on mixing ratio required) to the liquid fertilizer. The number of teaspoons of the formulation to add can be determined by the following formula:

Lbs or pts of product/acre X 11.4 = number of teaspoons of herbicide to add to 1 pint of fertilizer Gallons of fertilizer/acre 3. Close the jar and agitate until the herbicide(s) are evenly dispersed in the liquid fertilizer. If the materials DO NOT disperse well, it may be necessary to slurry the chemicals in water before adding to the fertilizer. 4. After dispersing the materials, add appropriate number of teaspoons of Pendimethalin 3.3 EC to the jar and shake well. Add water soluble concentrate herbicides to the mixture last and agitate. Let the mixture stand for 30 minutes and then observe the results. Look for signs of 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 provided that good agitation is maintained in the spray tank. c) If separation of the mixture occurs and agitation does not correct this problem, a compatibility agent is needed. 6. If the need for a compatibility agent is demonstrated, the following procedure is recommended: Using a clean quart jar, repeat step 1 above and add 1/2 teaspoon of the compatibility agent to the liquid fertilizer. Mix well and repeat steps 2, 3 and 4. If separation or precipitation occurs with the compatibility agent, DO NOT use Pendimethalin 3.3 EC with that specific liquid fertilizer.

Ground Applications (Band) Uniformly apply the broadcast equivalent rate and volume per acre. To determine these:

Band Width in Inches X Broadcast Rate = Band Rate Row Width in Inches per Acre per Acre

Band Width in Inches X Broadcast = Band Volume Row Width in Inches Volume per Acre per Acre

Ground Applications (Dry Bulk Fertilizer) Apply Pendimethalin 3.3 EC /dry bulk fertilizer mixtures only with ground equipment. DO NOT impregnate Pendimethalin 3.3 EC onto coated ammonium nitrate or limestone because these materials will not absorb the

8

herbicide. Dry fertilizer blends containing mixtures of ammonium nitrate or limestone may be impregnated with Pendimethalin 3.3 EC . A minimum of 200 pounds of impregnated dry bulk fertilizer, excluding the weight of ammonium nitrate or limestone, must be applied per acre. Use the following formula to determine the amount (in pints) of Pendimethalin 3.3 EC to be impregnated on a ton of dry bulk fertilizer based on the rate of fertilizer to be applied per acre:

2000 Pints of Pints of Pounds of Dry X Pendimethalin 3.3 EC = Pendimethalin 3.3 EC per Fertilizer per Acre (Labeled Rate per Acre) Ton of Fertilizer To impregnate Pendimethalin 3.3 EC on bulk fertilizer, use a closed rotary-drum mixer or other commonly used dry bulk fertilizer blender equipped with suitable spray equipment. Spray nozzles must be placed to provide uniform coverage of Pendimethalin 3.3 EC onto the fertilizer during mixing. Apply the Pendimethalin 3.3 EC /dry bulk fertilizer mixture with an accurately calibrated dry fertilizer spreader. The Pendimethalin 3.3 EC/dry bulk fertilizer mixture must be spread uniformly on the soil surface.

Chemigation Applications via Sprinkler Irrigation Systems Pendimethalin 3.3 EC may be applied as a chemigation treatment through sprinkler irrigation systems. Refer to the Crop-specific Information sections of this label for individual crops. DO NOT apply Pendimethalin 3.3 EC via chemigation to crops unless specified in the 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.

DO NOT apply this product through any other type of sprinkler irrigation system.

Uniform distribution of Pendimethalin 3.3 EC-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 properly calibrated (with water only) to ensure that the amount of Pendimethalin 3.3 EC applied corresponds to the labeled rate. Apply Pendimethalin 3.3 EC in 1/2 to 3/4 inches of water during the first sprinkler set (use at least 1 inch of water in the states of Texas, New Mexico and Oklahoma). Maintain agitation in the injection nurse tank to keep a uniform herbicide suspension during appl ication. When application is complete, flush the system with water.

Chemigation Instructions (for low volume micro sprinklers) Output of low volume sprinkler 4 to 50 gallons per hour (gph) per emitter. Point of application MUST be above ground. Run the irrigation system a sufficient amount of time prior to Pendimethalin 3.3 EC injection to ensure all emitters are functioning properly. After the system is operating properly, the length of injection should be such that at one period of time during the injection, the first and last emitters in the system contain Pendimethalin 3.3 EC treated water. Add Pendimethalin 3.3 EC to the supply tank already filled with the volume of water required for the injection period. Maintain proper agitation in the Pendimethalin 3.3 EC injection tank. Mix Pendimethalin 3.3 EC in clean water and inject down the line from filters. Following Pendimethalin 3.3 EC injection, flush the system for a period of time sufficient to clear the line of Pendimethalin 3.3 EC. (If Pendimethalin 3.3 EC application is made during a normal irrigation cycle, make the injection during the last stage.)

Chemigation Calibration (for low volume microsprinklers) Calculation of use rate is based on wetted area around emitters - NOT on tree acres.

To determine the correct amount of Pendimethalin 3.3 EC, use the following formula:

  1. Treated area per each emitter = A A = 3.14 x (radius x radius)
  2. The area in square feet wet in each acre = B B = A x emitters/acre 144
  3. The total area (in square feet) wet by your system = C C = B x acres covered by system.
  4. Rate per treated acre of Pendimethalin 3.3 EC (based on length of control desired) = R

9

Amount of Pendimethalin 3.3 EC S = C X R = qts of Pendimethalin 3.3 EC To inject = S 43,560

Example: If the average distance from emitter to perimeter of wetted area measured one inch below soil surface is 13 inches, then A= 3.14 x (13” x 13”), and A = 530.7 square inches. If there are 300 emitters per acre, then B = 530.7 x 300 and B = 1105.6 square feet 144 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 2.4 qts of Pendimethalin 3.3 EC, then

S = 22,112 x 2.4 and S = 1.2 qts. of Pendimethalin 3.3 EC should be injected into the system 43,560

Restrictions 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 applicat ion to a publ ic water system unless the pesticide label-prescribed safety devices for public water systems are in place.
  3. A person knowledgeable of the chemigation system and responsible for its operation, or under the supervision of the responsible person, shall shut the system down and make necessary adjustments should the need arise.
  4. The pesticide injection pipeline must contain a 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 either automatically or manually shut down.
  5. 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, such as a positive displacement injection pump (e.g. diaphragm pump) effectively designed and constructed of materials that are compatible with pesticides and capable of being fitted with a system interlock.
  6. The sprinkler chemigation system must contain 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.
  7. 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, the water from the public water system should be discharged into a reservoir tank prior to pesticide introduction.

Applications via Flooded Basin Irrigation Systems Pendimethalin 3.3 EC may be applied via flooded basin irrigation systems, but only to the following crops: bearing and nonbearing fruit and nut trees, nonbearing vineyards, and alfalfa.

Use Instructions and Restrictions for Flooded Basin Irrigation

  1. Pendimethalin 3.3 EC may be applied through flooded basin irrigation systems designed to uniformly distribute irrigation water along the soil surface. Solid set systems utilizing a tall riser for overhead application are excluded.
  2. Follow all label directions and restrictions for Pendimethalin 3.3 EC regarding rates per acre, timing of application and crop-specific restrictions and precautions .
  3. DO NOT connect an irrigation syste m used for pesticide appl ication 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 chem igation system and responsible for it s operation, or under the supervision of the responsible person, shall s hut the syst em down and make necessary adjustments should the need arise.
  5. Mix Pendimethalin 3.3 EC 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. Tail water (runoff water) from flood irrigation that contains Pendimethalin 3.3 EC must be re-circulated and contained in the field of initial application or used only on adjacent tree or vine crops or alfalfa for which Pendimethalin 3.3 EC is registered for this type of application,
  7. 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, such as a drop structure or weir box, to decrease potential for water source contamination from backflow water.
  8. Systems utilizing a pressurized water and pesticide injection system must meet the following requirements: x The system must co ntain a functional check valve, vacuum-relief va lve, and low-pressure drain appropriately located in the irrigation pipe to prevent water source contamination from backflow. x The pesticide injection pipeline must contain a functional automatic quick closing check valve to prevent flow of fluids back towards the injection pump. x The pesticide injection pipeline must also contain a functional, normally closed solenoid-operated valve located on the intake side of the injection pump and connected to the system interlock to prevent fluid from being withdrawn from the supply tank when the irrigation system is either automatically or manually shut down. x The system must contain a functional interlocking control to automatically shut off the pesticide injection pump when the water pump stops. x 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. x Systems must use a metering pump, such as 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, x Any alternative to the above safety devices must conform to the list of EPA-approved alternative devices.
  9. Be sure to regularly measure the flow in the field to ensure the correct amount of Pendimethalin 3.3 EC is being metered into the irrigation water and also regularly monitor to ensure that treated water is being uniformly distributed across the field. Flow rates through metering devices and distribution of Pendimethalin 3.3 EC can vary with water temperature and speed of water flow across the field.
  10. Uniform distribution of Pendimethalin 3.3 EC-treated irrigation water is the sole responsibility of the applicator and is required to avoid crop injury, lack of herbicide effectiveness, or illegal pesticide residues in the crop.
  11. If you have questions about calibration, contact state extension service specialists, equipment manufacturers or other experts.

Spray Drift Management Avoiding spray drift at the application site is the responsibility of the applicator. The interaction of many equipment and weather-related factors determine the potential for spray drift. The applicator and grower are responsible for considering all these factors when making decisions. It is the responsibility of the applicator to avoid spray drift onto nontarget areas.

11

Where states have more stringent regulations, they must be observed.

The applicator should be familiar with and take into account the information covered in the Spray Drift Advisories section presented below.

Spray Drift Advisories THE APPLICATOR IS RESPONSIBLE FOR AVOIDING OFF-SITE SPRAY DRIFT. BE AWARE OF NEARBY NON-TARGET 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 sufficient coverage and control. While applying larger droplets will reduce spray drift, the potential for drift will be greater if applications are made improperly or under unfavorable conditions.

Controlling Droplet Size Ground Boom x 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. x Pressure - Use the lowest spray pressure recommended for the nozzle to produce the target spray volume and droplet size. x Spray Nozzle - Use a spray nozzle that is designed for the intended application. Consider using nozzles designed to reduce drift.

Controlling Droplet Size Aircraft x Adjust Nozzle- Follow manufacturers 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.

Mandatory Spray Drift Management Aerial Applications: x 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. x Applicators are required to use a medium or coarser droplet size (ASABE S641). x 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. x Applicators must use ½ swath displacement upwind at the downwind edge of the field. x Nozzles must be oriented, so the spray is directed toward the back of the aircraft. x Do not apply during temperature inversions.

Ground Boom Applications: x Applicators must only apply with the nozzle height recommended by the manufacturer, but no more than 3 feet above the ground or crop canopy. x Applicators are required to use a medium or coarser droplet size (ASABE S572). x Do not apply when wind speeds exceed 15 mph at the application site. x Do not apply during temperature inversions. Boom-less Ground Applications: x Applicators are required to use a medium or coarser droplet size (ASABE S572/3) for all applications. x Do not apply when wind speeds exceed 15 mph at the application site. x Do not apply during temperature inversions.

12

RELEASE HEIGHT - Aircraft Higher release heights increase the potential for spray drift.

BOOM-LESS GROUND APPLICATIONS: Setting nozzles at the lowest effective height will help to reduce the potential for spray drift.

HANDHELD TECHNOLOGY APPLICATIONS: Take precautions to minimize 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 INVERSIONS 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 condition) 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.

Additives Spray adjuvants have little or no influence on performance of Pendimethalin 3.3 EC when applications are made prior to weed emergence. However, several tank mixes with Pendimethalin 3.3 EC require adjuvants to improve burndown of emerged weeds. Therefore, surfactants, liquid fertilizer (28%, 30%, or 32% UAN (urea ammonium nitrate) or ammonium sulfate), or crop oil concentrate may be used with Pendimethalin 3.3 EC tank mixes applied preplant, preemergence, or early postemergence to the crop. Follow the adjuvant directions on the tank mix partner's label.

When an adjuvant (or a specific adjuvant product, such as a drift control agent) is to be used with this product, the use of a Council of Producers and Distributors of Agrotechnology (CPDA) certified adjuvant is recommended. The recommended adjuvants must contain ingredients accepted by the EPA.

Tank Mixing Information Pendimethalin 3.3 EC may be applied in a tank mix or a sequential application with other herbicides registered for use in a given crop. Refer to the companion label for weeds controlled in addition to Pendimethalin 3.3 EC alone. When using tank mixtures or sequential applications with Pendimethalin 3.3 EC , always read the companion product label(s) to determine the specific use rates by soil types, weed species, and weed or crop growth stage. In addition, follow all precautions and restrictions including state and local use restrictions that may apply to specific products. Always follow the most restrictive label.

Precautions for All Use Sites x Pendimethalin 3.3 EC will not control established weeds. Destroy emerged weeds prior to application. x Pendimethalin 3.3 EC is most effective in controlling weeds mechanically incorporated or when incorporated into the weed germination zone by adequate rainfall or overhead irrigation after application. x When using tank mixtures with Pendimethalin 3.3 EC, always read the companion product label(s) to determine the specific use rates by soil types, weed species, and weed or crop growth stage. In addition, follow all precautions and restrictions including state and local use restrictions that may apply to specific products. Always follow the most restrictive label.

x In the event of a crop loss due to adverse weather conditions or other reasons, any crop registered for a preplant incorporated application of Pendimethalin 3.3 EC can be replanted without adverse effects the same year (see the Crop-specific Information section of this label for exceptions). If replanting is necessary, DO

14

NOT work the soil deeper than the treated zone. x Refer to the Crop-specific Information section of this label for crop-specific preharvest intervals and feeding and grazing restrictions.

Restrictions for All Use Sites x DO NOT exceed the maximum labeled rate for any soil type.

Crop Rotation Restrictions x Use of Pendimethalin 3.3 EC in accordance with label directions is expected to result in normal growth of rotational crops in most situations; however, various environmental and agronomic factors, such as arid conditions, make it impossible to eliminate all risks associated with the use of this product and, therefore, rotational crop injury is always possible. Soil characteristics and environmental conditions which may contribute to crop stress that may be accentuated by the use of Pendimethalin 3.3 EC include: coarse soils, compaction, high salinity, eroded knolls/hilltops, cold and/or wet soils, drought, and heavy rainfall soon after application. x When Pendimethalin 3.3 EC is used in tank mix or sequential combinations, refer to labels of other herbicides for additional rotational crop restrictions. x Restrictions for rotational cropping after the use of Pendimethalin 3.3 EC are dependent on the application use rate of Pendimethalin 3.3 EC in the primary crop. The user must thoroughly read the following restrictions to determine the rotational crops for their specific situation, according to application use rate.

I. Rotational Crop Restrictions Following Applications of Pendimethalin 3.3 EC to Field and Row Crops

Rotational Crop Restrict ions Following Applications of Pendimet halin 3.3 EC to Orchard, Grove, and Vineyard Crops In the growing season following application of Pendimethalin 3.3 EC to bearing fruit and nut trees, plant only those crops for which Pendimethalin 3.3 EC is labeled for pre-plant incorporated treatment or crop injury may occur. DO NOT rotate to other crops (except for nut crops, fruit trees, or grapes) for 24 months following a Pendimethalin 3.3 EC application to bearing fruit or nut trees.

Use Area Regional Map for Rate Determination

Crop-specific Information Crop Injury Disclaimer. Pendimethalin 3.3 EC use may result in crop injury, loss or damage to certain crops under a number of conditions, including but not limited to agronomic, cultural, mechanical, and environmental. Numerous risks of loss or damage to certain crops may be associated with the use of Pendimethalin 3.3 EC even when directions for use are followed completely. The user or grower should take all such risks into consideration before deciding to apply the product. Winfield Solutions, LLC recommends testing on a small portion of the target crop to determine if damage is likely to occur. Each grower who is considering the product for such use should test Pendimethalin 3.3 EC in order to determine its suitability. A grower should use Pendimethalin 3.3 EC only to the extent that in his sole opinion the benefit of Pendimethalin 3.3 EC use outweighs the potential injury to the grower's crop.

16

In addition, many factors can affect crop growth and/or yield, including but not limited to, insects, diseases, weed competition, poor seed quality, improper planting depth, mechanical cultivation, poor weather (such as freezing or excessive wind, rain, heat, or cold), lack of or excessive moisture, crusting, fertility, or hardpans. Risk of loss or damage to crops may be associated with the use of Pendimethalin 3.3 EC and contribute to poor stands due to failure of crop to emerge, swelling of roots or other below-ground plant parts, less vigorous plant growth and development, and reduction in yield potential.

Pendimethalin 3.3 EC may also cause injury to sensitive rotational crops. ALFALFA (Grown for Forage, Hay, or Seed) Pendimethalin 3.3 EC may be applied by ground, air, chemigation, flooded basin irrigation systems, or on dry bulk fertilizer.

Use Methods, Timings and Rates Established Alfalfa for Forage/Hay (defined as alfalfa planted in the fall or spring that has gone through a first cutting/mowing): Uniformly apply Pendimethalin 3.3 EC at a broadcast rate of 1.2 to 4.8 quarts per acre prior to weed emergence. Applications can be made in the fall after the last mowing/cutting, during winter dormancy, in the spring, or between cuttings.

Make applications prior to the alfalfa reaching 6 inches in regrowth. Established Alfalfa Grown for Seed Production (defined as alfalfa planted in the fall or spring that has gone through a summer season of cutting/mowing):

Uniformly apply Pendimethalin 3.3 EC at a broadcast rate of 1.2 to 4.8 quarts per acre prior to weed emergence in one of the following ways:

  1. Apply to dormant established alfalfa.
  2. Apply before alfalfa exceeds 10 inches in height after first mowing/beating.
  3. Once the alfalfa reaches 10 inches in height or if the alfalfa has been mowed/beaten two or more times, Pendimethalin 3.3 EC must be applied with drop nozzles directing the spray so that there is little to no contact with the foliage.

Seedling Alfalfa (defined as alfalfa planted in the fall or spring which has NOT gone through a cutting/mowing): Uniformly apply Pendimethalin 3.3 EC at a broadcast rate of 1.2 to 2.4 pints per acre prior to weed emergence.

Regardless of tillage system, plant corn at least 1-1/2 inches deep and completely cover with soil. In conventional tillage systems, plant into a seedbed that is firm and free of clods and trash. Use only where adequate tillage is practiced to provide good soil coverage of the corn seed. In no-till systems, utilize a no-till planter that is capable of planting through crop residue. The use of no-till planters under conditions that do not allow good soil coverage of the corn seed can result in reduced crop stand or injury if Pendimethalin 3.3 EC contacts the germinating corn seed. Check equipment to ensure good seed coverage. Pendimethalin 3.3 EC or Pendimethalin 3.3 EC tank mix combination treatments are most effective in controlling weeds when adequate rainfall or overhead irrigation is received within 7 days after application. If cultivation is necessary because of soil crusting or weed germination, use shallow tillage and make certain corn seeds are below the tilled area.

Additional Weeds Controlled: In addition to the weeds listed in Table 1, Pendimethalin 3.3 EC will control the following weeds in corn with CULTI-SPRAY application: wild proso millet and shattercane.

Use Methods and Timings Preemergence - Apply after planting but before weeds and crop emerge.

Postemergence - Apply postemergence until field corn is 30 inches tall (20 to 24 inches tall for pop, seed, and sweet corn) or in the V8 growth stage, whichever is more restrictive. If the corn canopy prevents applications from reaching the soil, use drop nozzles and apply as a directed spray.

CULTI-SPRAY - Apply Pendimethalin 3.3 EC alone or Pendimethalin 3.3 EC plus atrazine when field corn is at least 4 inches tall until last cultivation (layby). Pendimethalin 3.3 EC plus atrazine must be applied before the field com reaches 12 inches in height. DO NOT exceed 1.2 lbs ai per acre of atrazine, as specified on the atrazine label. Under situations of low rainfall or soil moisture when deep germinating weeds such as shattercane or field sandbur are anticipated, mechanical incorporation will provide best results. If cultivation is needed after application and incorporation of Pendimethalin 3.3 EC, ensure that the cut depth is no deeper than the depth of cut used to incorporate.

Chemigation Applications Pendimethalin 3.3 EC may be applied through sprinkler irrigation systems. Follow all use directions and restrictions pertaining to Chemigation in the Spraying Instructions section of this label.

Precautions for Use on Potatoes x Application of Pendimethalin 3.3 EC on White Rose variety potatoes during or followed by cool and/or wet weather conditions may result in crop injury.

Restrictions for Use on Potatoes x DO NOT apply to sweet potatoes or yams. x DO NOT apply preplant. x DO NOT make more than one application of Pendimethalin 3.3 EC per season. RICE

Pendimethalin 3.3 EC may be applied as a pre-flood, preemergence application in dry-seeded or drilled rice or as a delayed preemergence application in drilled dry-seeded rice or as an early postemergence application in dry- seeded rice. Treatments may be applied to conventional, reduced or minimum tillage, and no-till (stale seedbed) rice. Ensure that the seedbed is firm and free of clods and prepared to allow for good seed coverage. The 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 Pendimethalin 3.3 EC contacts germinating rice seed.

Additional Weeds Controlled: In addition to the weeds listed in Table 1, Pendimethalin 3.3 EC will control the following weeds in rice: junglerice and sprangletop.

Use Methods and Timings Pre-Flood Preemergence - Pendimethalin 3.3 EC may be applied for preemergence weed control as a pre- flood, pre-rice germination herbicide in lightly incorporated dry-seeded rice or on drilled rice.

SEEDING DIRECTIONS: For all rice seed incorporation methods, seed must be incorporated shallowly or no more than 1 inch below soil surface. Seed left on the surface may be injured or killed by Pendimethalin 3.3 EC . However, it is recommended that 15 to 20% of seed total be visible at surface in order to ensure that seed is not covered too deeply. Seeding rates should be increased by a percentage corresponding to the amount of seed left on the surface. Adjust seeding ratios to meet individual practices, incorporation depths and field conditions.

EXAMPLE: Target seeding rate is 150 lbs per acre. If approximately 15% of seed is left on soil surface seeding rate should then be increased 22.5 lbs per acre to 177.5 lbs per acre

Seeding depths can be affected by soil textures, tillage practices, irrigation, and methods of mechanical incorpora- tion. Seed that is incorporated either mechanically and/or by irrigation flush must remain at a shallow depth of no more than 1 inch below the soil surface. Fields where rice seed is incorporated too deeply will experience reduced

33

crop stands.

Following are examples of typical implements that can be used for rice seed incorporation: rice roller/ridger, ring roller, light harrow, or flat roller. Regardless of the implement or method of incorporation used, seed incorporation must be less than 1 inch below the soil surface.

After rice seed is incorporated, uniformly apply to soil surface as broadcast spray the tank mixture of Pendimethalin 3.3 EC at 2.4 pints per acre plus FirstChoice ® SafeGuard spray adjuvant at 1.6 pints per acre. Use of Pendimethalin 3.3 EC without tank mixing with FirstChoice SafeGuard spray adjuvant can result in crop injury and loss of rice stand.

After herbicide application, flush field with irrigation water with method best employed to facilitate a thorough soaking of field and a rapid drain. Tail water (runoff water) from flood irrigation that contains Pendimethalin 3.3 EC must be re-circulated and contained in the field of initial application or used only on adjacent crops for which Pendimethalin 3.3 EC (or other pendimethalin-based products) is registered for use.

Rice seed covered with water for longer than 8 days may result in reduced stand and weed control.

Delayed Preemergence - Apply Pendimethalin 3.3 EC alone or with tank mix partner for delayed preemergence weed control in grain-drilled, dry-seeded rice. Apply Pendimethalin 3.3 EC alone or in tank mixture to levees after the levees are pulled and planted. Exposed seeds that come in contact with Pendimethalin 3.3 EC may be injured. Apply only when growing conditions favor vigorous rice growth. Ensure that the seedbed has adequate moisture for seed germination. Not for use in California.

Uniformly apply the specified rate of Pendimethalin 3.3 EC after rice planting and before rice and weed emergence (spiking). Apply after the rice seed has absorbed water and germinated and after the soil has been previously sealed over the seed by at least 1 inch of rainfall or by irrigation (flush). If the soil has not been sealed by rain or flush, apply when 80 percent of germinated seeds have a primary root (radicle) or shoot at least 1/2-inch long. If there is insufficient moisture, flushing is important before Pendimethalin 3.3 EC application to supply moisture for root (radicle) initiation and for vigorous rice and weed growth. If applied to soil prior to these conditions or to cracked soil, stand reduction or stunting of rice may occur. Under some conditions, use of gibberellic acid-treated seed, heavy rainfall after application, or flushing after application may result in herbicide injury to rice. Rice can overcome moderate injury with appropriate cultural practices. Due to the residual activity of Pendimethalin 3.3 EC, this treatment may be applied if rice is too small to maintain a flood on the field for weed control. However, proper water management practices must be followed for normal rice growth and activity of Pendimethalin 3.3 EC. Early Postemergence - Apply Pendimethalin 3.3 EC as a tank mix partner. Base applications on weed and crop size guidelines of the tank mix partner. DO NOT apply to fields with standing water. If necessary, fields may be flushed prior to treatment to produce vigorous rice and weed growth. Since soil and weeds must be completely exposed to spray coverage, ensure that there is no flood water on the field at the time of application. Cloddy soil, standing water (puddles) at the time of application, or cra cks in the soil that form a fter application may result in reduced weed control. Because of residual activity of Pendimethalin 3.3 EC, this treatment may be applied if rice is too small to maintain a flood on the field for weed control. However, proper water management practices must be followed for normal rice growth and activity of Pendimethalin 3.3 EC. Since the residual activity of Pendimethalin 3.3 EC is activated by moisture, Pendimethalin 3.3 EC is most effective in controlling emerging weeds when adequate rainfall or irrigation (flush) is received within 7 days after application.

SUNFLOWERS

Pendimethalin 3.3 EC may be applied preplant incorporated in all states. Fall preplant incorporated applications may be made in North Dakota. South Dakota and Minnesota only. Pendimethalin 3.3 EC may be applied preemergence in conventional tillage sunflowers, except in the state of California.

Plant sunflowers 1.5 inches to 2 inches deep and completely cover with soil.

Use Methods and Timings Preplant Incorporated (Spring) - Apply up to 60 days prior to planting and incorporate within 7 days after application.

Preplant Incorporated (Fall applications in North Dakota. South Dakota and Minnesota) Apply Pendimethalin 3.3 EC and immediately incorporate in late fall prior to planting sunflowers the following spring. Apply Pendimethalin 3.3 EC i n the late fall when soil temperatures are 45° F or below but before the ground freezes. DO NOT apply when the air temperature is below 45° F.

Prior to sunflower planting in the spring, make at least one additional shallow incorporation, to fields treated with Pendimethalin 3.3 EC Make the spring incorporation at an angle to the last tillage operation.

Preemergence - Apply Pendimethalin 3.3 EC at planting or up to 2 days after planting. Preemergence applications of Pendimethalin 3.3 EC to sunflowers may increase the likelihood of crop injury, especially when sunflowers are grown in stress situations, such as compacted soils. Decreased herbicide performance compared to preplant incorporated applications may also result from a preemergence application. If dry conditions with limited precipitation exist or unseasonably cool temperatures following planting are forecast, apply Pendimethalin 3.3 EC prior to planting and mechanically incorporate with tillage.
