Groundwater Advisory This product has properties and characteristics associated with chemicals detected in groundwater. This product may leach into groundwater if used in areas where soils are permeable, particularly where the water table is shallow. Surface Water Advisory This product may impact surface water quality due to runoff of rain water. This is especially true for poorly draining soils and soils with shallow ground water. This product is classified as having high potential for reaching surface water via runoff for several weeks or more after application. A level, well-maintained vegetative buffer strip between areas to which this product is applied and surface water features such as ponds, streams, and springs will reduce the potential loading of this product from runoff water and sediment. Runoff of this product will be greatly reduced by avoiding applications when rainfall or irrigation is expected to occur within 48 hours. Windblown Soil Particles Advisory This product has the potential to move off-site due to wind erosion. Soils that are subject to wind erosion usually have a high silt and/or fine to very fine sand fractions and low organic matter content. Other factors which can affect the movement of windblown soil include the intensity and direction of prevailing winds, vegetative cover, site slope, rainfall, and drainage patterns. Avoid applying this product if prevailing local conditions may be expected to result in off-site movement. Non-target Organism Advisory This product is toxic to plants and may adversely impact the forage and habitat of non-target organisms, including pollinators, in areas adjacent to the treated area. Protect the forage and habitat of non-target organisms by minimizing spray drift. For further guidance and instructions on how to minimize spray drift, refer to the Spray Drift Management section of this label. DIRECTIONS FOR USE It is a violation of Federal law to use this product in a manner inconsistent with its labeling. DO NOT apply this product in a way that will contact workers or other persons, either directly or through drift. Only protected handlers may be in the area during application. For any requirements specific to your State or Tribe, consult the agency responsible for pesticide regulation. T-PAC™ herbicide is for use on wheat (including durum), barley, oat, triticale and fallow in many states.

This Standard contains requirements for the protection of agricultural workers on farms, forests, nurseries, and greenhouses, and handlers of agricultural pesticides. It contains requirements for training, decontamination, notification, and emergency assistance. It also contains specific instructions and exceptions pertaining to the statements on this label about personal protective equipment (PPE) and restricted-entry interval. The requirements in this box only apply to uses of this product that are covered by the Worker Protection Standard. DO NOT enter or allow worker entry into treated areas during the restricted entry interval (REI) of 12 hours. PPE required for early entry to treated areas that is permitted under the Worker Protection Standard and that involves contact with anything that has been treated, such as plants, soil, or water, is: Coveralls. Chemical-resistant gloves made of any waterproof material. Shoes plus socks. PRODUCT INFORMATION T-PAC™ herbicide is a soluble granule that is used for selective postemergence weed control in wheat (including durum), barley, oat, triticale and fallow. The best control is obtained when T-PAC™ herbicide is applied to young, actively growing weeds. The use rate will depend on weed spectrum and size of weed at time of application. The degree and duration of control may depend on the following: • weed spectrum and infestation intensity • weed size at application • environmental conditions at and following treatment T-PAC™ herbicide is noncorrosive, nonflammable, nonvolatile, and does not freeze. T-PAC™ herbicide must be mixed, and completely dissolved in water and applied as a uniform broadcast spray. RESTRICTIONS Injury to or loss of adjacent sensitive crops, desirable trees or vegetation may result from failure to observe the following: • DO NOT apply to wheat, barley, oats, and triticale underseeded with another crop. • DO NOT harvest wheat or barley sooner than 45 days after the last application of T-PAC™ herbicide. • DO NOT apply, drain or flush equipment on or near desirable trees or other plants or on areas where their roots may extend, or in locations where the chemical may be washed or moved into contact with their roots. • DO NOT use on lawns, walks, driveways, tennis courts, or similar areas. Prevent drift of spray to desirable plants. • DO NOT apply this product through any type of irrigation system. • DO NOT apply T-PAC™ herbicide by air in the state of New York. PRECAUTIONS Injury to or loss of adjacent sensitive crops, desirable trees or vegetation may result from failure to observe the following: • Take all necessary precautions to avoid all direct or indirect contact (including spray drift) with non-target plants or areas. Carefully observe all sprayer cleanup instructions both prior to and after using this product, as spray tank residue may damage crops other than wheat, barley, oats, and triticale. Dry, dusty field conditions may result in reduced control in wheel track areas. T-PAC™ herbicide must not be applied to wheat, barley, oats, and triticale that is stressed by severe weather conditions, drought (including low levels of subsoil moisture), low fertility, water-saturated soil, disease, or insect damage, as crop injury may result. Risk of injury is greatest when crop is in the 2 to 5- leaf stage. Severe winter stress, drought, disease, or insect damage following application also may result in crop injury.

Wheat, barley, oats, and triticale may differ in their response to various herbicides. FMC advises that you first consult your state experiment station, university, or extension agent as to sensitivity to any herbicide. If no information is available, limit the initial use of T-PAC™ herbicide to a small area. Under certain conditions, including heavy rainfall, prolonged cold weather (daily high temperature less than 50 oF), or wide fluctuations in day/night temperatures prior to or soon after T-PAC™ herbicide application, temporary discoloration and/or crop injury may occur. To reduce the potential of crop injury, tank mix T-PAC™ herbicide with 2,4-D (ester formulations perform best–see “Tank Mixtures” section of this label) and apply after the crop is in the tillering stage of growth. It is the pesticide user’s responsibility to ensure that all products 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 restrictive directions for use and precautionary statements of each product in the tank mixture.). ENVIRONMENTAL CONDITIONS AND BIOLOGICAL ACTIVITY T-PAC™ herbicide is absorbed primarily through the foliage of plants, rapidly inhibiting the growth of susceptible weeds. One to 3 weeks after application to weeds, leaves of susceptible plants appear chlorotic, and the growing point subsequently dies. T-PAC™ herbicide provides the best control in vigorously growing crops that shade competitive weeds. Weed control in areas of thin crop stand or seeding skips may not be as satisfactory. However, a crop canopy that is too dense at application can intercept spray and reduce weed control. The herbicidal action of T-PAC™ herbicide may be affected in crops stressed from adverse environmental conditions (including extreme temperatures or moisture), abnormal soil conditions, cultural practices, or variations in crop variety. In warm, moist conditions, the expression of herbicide symptoms is accelerated; in cold, dry conditions, expression of herbicide symptoms is delayed. In addition, weeds hardened-off by drought stress are less susceptible to T-PAC™ herbicide. WEED RESISTANCE MANAGEMENT T-PAC™ herbicide, which contains the active ingredients Thifensulfuron methyl and Tribenuron methyl is a group 2 herbicide based on the mode of action classification system of the Weed Science Society of America. Proactively implementing diversified weed control strategies to minimize selection for weed populations resistant to one or more herbicides is a best practice. A diversified weed management program may include the use of multiple herbicides with different sites of action and overlapping weed spectrum with or without tillage operations and/or other cultural practices. Research has demonstrated that using the labeled rate and directions for use is important to delay the selection for resistance. The continued effectiveness of this product depends on the successful implementation of a weed resistance management program. To aid in the prevention of developing weeds resistant to this product, users should: • Scout fields before application to ensure herbicides and rates will be appropriate for the weed species and weed sizes present. • Start with a clean field, using either a burndown herbicide application or tillage. • Control weeds early when they are relatively small (less than 4 inches). • Apply full rates of T-PAC™ herbicide for the most difficult to control weed in the field at the specified time (correct weed size) to minimize weed escapes. • Scout fields after application to detect weed escapes or shifts in control of weed species. • Control weed escapes before they reproduce by seed or proliferate vegetatively. • Report any incidence of non-performance of this product against a particular weed to your FMC representative, local retailer, or county extension agent. • Contact your FMC representative, crop advisor, or extension agent to find out if suspected resistant weeds to these MOAs have been found in your region. DO NOT assume that each listed weed is being controlled by multiple sites

5

of action. Products with multiple active ingredients are intended to broaden the spectrum of weeds that are controlled. Some weeds may be controlled by only one of the active ingredient in this product. • If resistance is suspected, treat weed escapes with an herbicide having a site of action other than Group 2 and/or use nonchemical methods to remove escapes, as practical, with the goal of preventing further seed production. • Suspected herbicide-resistant weeds may be identified by these indicators:

• Failure to control a weed species normally controlled by the herbicide at the dose applied, especially if control is achieved on adjacent weeds;
• A spreading patch of non-controlled plants of a particular weed species; and
• Surviving plants mixed with controlled individuals of the same species. Additionally, users should follow as many of the following herbicide resistance management practices as is practical: • Use a broad spectrum soil-applied herbicide with other sites of action as a foundation in a weed control program. • Utilize sequential applications of herbicides with alternative sites of action. • Rotate the use of this product with non-Group 2 herbicides. • Avoid making more than two applications of T-PAC™ herbicide and any other Group 2 herbicides within a single growing season unless mixed with an herbicide with a different site of action with an overlapping spectrum for the difficult-to-control weeds. • Incorporate non-chemical weed control practices, including mechanical cultivation, crop rotation, cover crops and weed-free crop seeds, as part of an integrated weed control program. • Use good agronomic principles that enhance crop development and crop competitiveness. • Thoroughly clean plant residues from equipment before leaving fields suspected to contain resistant weeds. • Manage weeds in and around fields, during and after harvest to reduce weed seed production. INTEGRATED PEST MANAGEMENT FMC recommends the use of Integrated Pest Management (IPM) programs to control pests. This product may be used as part of an Integrated Pest Management (IPM) program that can include biological, cultural, and genetic practices aimed at preventing economic pest damage. Application of this product should be based on IPM principles and practices including field scouting or other detection methods, correct target pest identification, population monitoring, and treating when target pest populations reach locally determined action thresholds. Consult your state cooperative extension service, professional consultants or other qualified authorities to determine appropriate action treatment threshold levels for treating specific pest/crop systems in your area.

It is the pesticide user’s responsibility to ensure that all products are registered for the intended use. Read and follow the applicable restrictions, limitations and directions for use on all product labels involved in tank mixing. Users must follow the most restrictive directions for use and precautionary statements of each product in the tank mixture. If the instructions on the tank mix partner label conflict with this T-PAC™ herbicide, then DO NOT use in a tank mixture with T-PAC™ herbicide. TANK MIXTURES It is the pesticide user’s responsibility to ensure that all products are registered for the intended use. Read and follow the applicable restrictions, limitations and directions for use on all product labels involved in tank mixing. Users must follow the most restrictive directions for use and precautionary statements of each product in the tank mixture. If the instructions on the tank mix partner label conflict with this T-PAC™ herbicide, then DO NOT use in a tank mixture with T-PAC™ herbicide. T-PAC™ herbicide may be tank mixed with one or more suitable registered herbicides to control weeds listed as suppressed, weeds resistant to T-PAC™ herbicide or weeds not listed under Weeds Controlled. Read and follow all manufacturer’s label instructions for the companion herbicide. If those instructions conflict with this label, DO NOT tank mix the herbicide with T-PAC™ herbicide. T-PAC™ herbicide can also be mixed with registered fungicides, insecticides, or liquid fertilizer for use on wheat, barley, or fallow. With Other Grass Control Products T-PAC™ herbicide can be tank mixed with grass control products. Antagonism generally does not occur. Under certain environmental conditions, however, antagonism to Group 1 graminicides can occur. This may be reduced by using the higher rate of the graminicide. FMC advises that you first consult your state experiment station, university, or extension agent, Agricultural dealer, or FMC representative as to the potential for antagonism before using the mixture. If no information is available, limit the initial use of T-PAC™ herbicide and the grass product to a small area. With Insecticides or Fungicides T-PAC™ herbicide may be tank mixed or used sequentially with insecticides (or fungicides) registered for use on cereal grains. However, under certain conditions (drought stress, or if the crop is in the 2-4 leaf stage), tank mixes or sequential applications of T-PAC™ herbicide with organophosphate insecticides may produce temporary crop yellowing or, in severe cases, crop injury. Test these mixtures in a small area before treating large areas. However, review all insecticide and fungicide labels for restrictions. DO NOT use T-PAC™ herbicide plus products containing malathion, as crop injury will result. With Liquid Nitrogen Solution Fertilizer Liquid nitrogen fertilizer solutions may be used as a carrier in place of water. Run a tank mix compatibility test before mixing T-PAC™ herbicide in fertilizer solution. DO NOT add T-PAC™ herbicide directly to liquid nitrogen fertilizer; the granules will not dissolve. T-PAC™ herbicide must be thoroughly mixed with clean water before it is added to liquid nitrogen fertilizer. If granules remain when the mixture is poured out, add more clean water and mix until all granules have disappeared. Ensure that the agitator is running when the T-PAC™ herbicide premix is added. Use of this mixture may result in temporary crop yellowing and stunting. If using low rates of liquid nitrogen fertilizer in the spray solution (less than 50% of the spray solution volume), the addition of surfactant is necessary. Add surfactant at 1/4 qt - 1 qt per 100 gal of spray solution (0.06 -0.25% v/v) based on local guidance. When using high rates of liquid nitrogen fertilizer solution in the spray solution, adding surfactant increases the risk of crop injury. Consult your agricultural dealer, consultant, fieldman, or FMC representative for specific instructions before adding an adjuvant to these tank mixtures.

13

If 2,4-D or MCPA is included with T-PAC™ herbicide and fertilizer mixture, ester formulations tend to be more compatible (see manufacturer’s label). Additional surfactant is not needed when using T-PAC™ herbicide in tank mix with 2,4-D ester or MCPA ester and liquid nitrogen fertilizer solutions. DO NOT use low rates of liquid nitrogen fertilizer solution as a substitute for a surfactant. DO NOT use with liquid fertilizer solutions with a pH less than 3.0. CROP ROTATION Labeled crops may be planted at specified time intervals following application of labeled rates of T-PAC™ herbicide. Use the time intervals listed below to determine the required time interval before planting. Time Interval Before Planting* (days after treatment with T-PAC™ herbicide) Crop Days Barley, Rice, Triticale, and Wheat (including durum) 0 Soybeans 7** Cotton, Field Corn, and Grain Sorghum 14** Sugarbeets, Winter Rape, and Canola 60 Any other crop 45

• Refer to individual product labels to determine rotational crop restrictions when tank mixtures are used. **Where T-PAC™ herbicide is used on light textured soils, including sands and loamy sands, extend time to planting by 7 additional days. Where T-PAC™ herbicide is used on high pH soils (>7.9), extend time to planting by 7 additional days.

• See SPECIFIC WEED PROBLEMS for more information. **Partial control: A visual reduction of weed population as well as a significant loss of vigor. For better results, use the highest specified rate of T-PAC™ herbicide per acre and include a tank mix partner including 2,4-D, MCPA, bromoxynil containing herbicides or dicamba containing herbicides.

15

SPECIFIC WEED PROBLEMS Canada thistle: For control in wheat and barley, use 0.8 oz/A T-PAC™ herbicide plus surfactant when all thistles are 4" to 8" with 2" to 6" of new growth. Make the application in the spring. Control will be improved by using T- PAC™ herbicide in combination with 2,4-D, dicamba, WideMatch® herbicide, or Colt® AS herbicide. Refer to TANK MIXTURES. Common cocklebur, Common ragweed, Lanceleaf sage: In wheat and barley, apply T-PAC™ herbicide at 0.4 to 0.8 oz/A in combination with 2,4-D at rates from 1/4 to 3/8 lb active ingredient (ester formulations work best) when weeds are small and actively growing. When using 1/4 lb active ingredient of 2,4-D, be sure to add surfactant at the rate of 1/4 to 1/2 quart per 100 gallons of spray solution (0.06 to 0.125% v/v--use the higher rate under stress conditions). Corn gromwell, Wild buckwheat: For control in wheat and barley, use 0.8 oz/A T-PAC™ herbicide plus surfactant. Kochia, Russian thistle, Prickly lettuce: Naturally occurring resistant biotypes of these weeds are known to occur. For best results, use T-PAC™ herbicide in a tank mix with Colt + Sword® herbicide, Colt + Salvo® herbicide, dicamba and 2,4-D; or Bromoxynil (including Buctril® herbicide) and 2,4-D (3/4 - 1 pt Buctril herbicide + 1/4 - 3/8 lb active ingredient 2, 4-D ester). For improved broadleaf weed control including kochia, T-PAC™ herbicide can also be tank mixed with WideMatch® herbicide, Colt® AS herbicide or Starane® NXT herbicide. T-PAC™ herbicide must be applied in the spring when weeds are 2” to 4" tall or 2” to 4" across and are actively growing. Refer to the Tank Mixtures section of this label for additional details. SPRAY ADJUVANTS Always include a spray adjuvant with applications of T-PAC™ herbicide. In addition to a spray adjuvant, an ammonium nitrogen fertilizer may be used. Consult your Ag dealer or applicator, local FMC fact sheets, technical bulletins, and service policies prior to using an adjuvant system. If another herbicide is tank mixed with T-PAC™ herbicide, select adjuvants authorized for use with both products. Products must contain only EPA-exempt ingredients (40CFR 1001). Nonionic Surfactant (NIS) • Apply 0.06 to 0.50% volume/volume (1/2 pt to 4 pt per 100 gal of spray solution). • Surfactant products must contain at least 60% nonionic surfactant with a hydrophilic/lipophilic balance (HLB) greater than 12. See the Tank Mixtures section of this label for additional information. Petroleum Crop Oil Concentrate (COC) or Modified Seed Oil (MSO) • Apply at 1% volume/volume (1 gal per 100 gal spray solution) or 2% volume/volume under arid conditions. • Oil adjuvants must contain at least 80% high quality, petroleum (mineral) or modified vegetable seed oil with at least 15% surfactant emulsifiers. Special Adjuvant Types • Combination adjuvant products may be used at doses that provide the required amount of NIS, COC, MSO and/or ammonium nitrogen fertilizer. Consult product literature for use rates and restrictions. • In addition to the adjuvants specified above, other adjuvant types may be used if they provide the same functionality and have been evaluated and approved by FMC product management. Consult separate FMC technical bulletins for detailed information before using adjuvant types not specified on this label. Ammonium Nitrogen Fertilizer • Use 2 qt/acre of a high-quality urea ammonium nitrate (UAN), including 28%N or 32%N, or 2 lb/acre of a spray- grade ammonium sulfate (AMS). Use 4 qt/acre UAN or 4 lb/acre AMS under arid conditions. APPLICATION TIMING Since T-PAC™ herbicide has very little or no soil activity, it controls only those weeds that have germinated; therefore, apply T-PAC ™ herbicide when all or most of the weeds have germinated. Annual broadleaf weeds must be past the cotyledon stage, actively growing, and less than 4" tall or wide. Rainfall immediately after treatment can wash T-PAC™ herbicide off of weed foliage, resulting in reduced weed control. Several hours of dry weather are needed to allow T-PAC™ herbicide to be sufficiently absorbed by weed foliage.

16

GROUND APPLICATION For optimum spray distribution and thorough coverage, use flat-fan or low-volume flood nozzles. For flat-fan nozzles, use a spray volume of at least 5 gal per acre (GPA). For flood nozzles on 30” spacings, use at least 10 GPA, flood nozzles no larger than TK10 (or the equivalent), and a pressure of at least 30 psi. For 40” nozzle spacings, use at least 13 GPA; for 60” spacings use at least 20 GPA. It is essential to overlap the nozzles 100% for all spacings. Raindrop “RA” nozzles are not advised for T-PAC™ herbicide applications, as weed control performance may be reduced. Use screens that are 50-mesh or larger. AERIAL APPLICATION Use nozzle types and arrangements that provide optimum spray distribution and maximum coverage at 2 to 5 GPA. Use at least 3 GPA in Idaho, Oregon, or Utah. This product is limited to ground application only in the State of New York. See the Spray Drift Management section of this label. CHEMIGATION DO NOT apply this product through any irrigation system. PRODUCT MEASUREMENT T-PAC™ herbicide is measured using the T-PAC™ herbicide volumetric measuring cylinder. The degree of accuracy of this cylinder varies by + 7.5%. For more precise measurement, use scales calibrated in ounces. PESTICIDE HANDLING • Calibrate sprayers only with clean water away from the well site. • Make scheduled checks of spray equipment. • Ensure that all operation employees accurately measure pesticides. • Mix only enough product for the job at hand. • Avoid overfilling of spray tank. • DO NOT discharge excess material on the soil at a single spot in the field, grove, or mixing/loading station. • Dilute and agitate excess solution and apply at labeled rates or uses. • Avoid storage of pesticides near well sites. • When triple-rinsing the pesticide container, be sure to add the rinsate to the spray mix. MIXING INSTRUCTIONS DO NOT use with spray additives that alter the pH of the spray solution below pH 5.0 or above pH 9.0 as rapid product degradation can occur. Spray solutions of pH 6.0-8.0 allow for optimum stability of T-PAC™ herbicide.

1. Fill the tank 1/4 to 1/3 full of water.
2. While agitating, add the required amount of T-PAC™ herbicide
3. Continue agitation until the T-PAC™ herbicide is fully dissolved, at least 5 minutes.
4. Once the T-PAC™ herbicide is fully dissolved, maintain agitation and continue filling tank with water.
5. As the tank is filling, add tank mix partners and then add the required volume of spray adjuvant. Always add spray adjuvant last. Antifoaming agents may be used. DO NOT use with spray additives that alter the pH of the spray solution below pH 6.0 as rapid product degradation can occur. Spray solutions of pH 7.0 and higher allow for optimum stability of T-PAC™ herbicide.
6. Dispersed tank mix partners can settle if the tank mixture is not continually agitated. If settling occurs, thoroughly reagitate before using.
7. Apply T-PAC™ herbicide spray mixture within 24 hours of mixing to avoid product degradation.
8. If T-PAC™ herbicide and a tank mix partner are to be applied in multiple loads, fully dissolve the T-PAC™ herbicide in clean water prior to adding to the tank.

17

GRAZING Allow at least 7 days between application and grazing of treated forage. In addition, allow at least 7 days between application and feeding of forage from treated areas to livestock. Allow at least 30 days between application and feeding of hay from treated areas to livestock. Harvested straw may be used for bedding and/or feed. Allow at least 45 days between application and harvesting of grain. SPRAY EQUIPMENT For specific application equipment, refer to the manufacturer’s instructions for additional information on GPA, pressure, speed, nozzle types and arrangements, nozzle heights above the target canopy, etc. Be sure to calibrate air or ground equipment properly before application. Select a spray volume and delivery system that will ensure thorough coverage and a uniform spray pattern with minimum drift. Use higher spray volumes to obtain better coverage when crop canopy is dense. Avoid swath overlapping, and shut off spray booms while starting, turning, slowing, or stopping, to avoid injury to the crop. For additional information on spray drift refer to Spray Drift Management section of label. Continuous agitation is not required for T-PAC™ herbicide but may be required to keep tank-mix partners in solution or suspension. Refer to tank-mix partner labels for additional information. SPRAYER CLEANUP The spray equipment must be cleaned before T-PAC™ herbicide is sprayed. Follow the cleanup procedures specified on the labels of the previously applied products. If no directions are provided, follow the six steps outlined in "After Spraying T-PAC™ herbicide" in this label. AT THE END OF THE DAY It is advised that during periods when multiple loads of T-PAC™ herbicide are applied, at the end of each day of spraying, the interior of the tank be rinsed with fresh water and then partially filled, and the boom and hoses flushed. This will prevent the buildup of dried pesticide deposits which can accumulate in the application equipment. AFTER SPRAYING T-PAC™ HERBICIDE AND BEFORE SPRAYING CROPS OTHER THAN WHEAT AND BARLEY To avoid subsequent injury to desirable crops, thoroughly clean all mixing and spray equipment immediately following applications of T-PAC™ herbicide as follows:

1. Empty the tank and drain the sump completely.
2. Spray the tank walls with clean water using a minimum volume of 10% of the tank volume. Circulate the water through the lines, including all by-pass lines, for at least two minutes. Flush the boom well and empty the sprayer. Completely drain the sump.
3. Repeat step 2.
4. Remove the nozzles and screens and clean separately in a bucket containing water. The rinsate solution may be applied to the crop(s) specified on this label. DO NOT exceed the maximum-labeled use rate. If cleaners are used, consult the cleaner label for rinsate disposal instructions. If no instructions are given, dispose of the rinsate on site or at an approved waste disposal facility. Notes:
5. Always start with a clean spray tank.
6. Steam-cleaning aerial spray tanks is advised to facilitate the removal of any caked deposits.
7. When T-PAC™ herbicide is tank mixed with other pesticides, all cleanout procedures for each product must be examined and the most rigorous procedure must be followed.
8. In addition to this cleanout procedure, all pre-cleanout guidelines on subsequently applied products must be followed as per the individual labels.

MANDATORY SPRAY DRIFT MANAGEMENT Ground Boom Applications: • Apply with the nozzle height recommended by the manufacturer, but no more than 3 feet above the ground or crop canopy. • For applications prior to the emergence of crops and target weeds, applicators are required to use a Coarse or coarser droplet size (ASABE S572.1). • For all other applications, applicators are required to use a Medium or coarser droplet size (ASABE S572.1). • DO NOT apply when wind speeds exceed 10 miles per hour at the application site. • DO NOT apply during temperature inversions. Aerial Applications: • DO NOT release spray at a height greater than 10 feet above the vegetative canopy, unless a greater application height is necessary for pilot safety. • For applications prior to the emergence of crops and target weeds, applicators are required to use a Coarse or coarser droplet size (ASABE S572.1). • For all other applications, applicators are required to use a Medium or coarser droplet size (ASABE S572.1). • The boom length must not exceed 65% of the wingspan for airplanes or 75% of the rotor blade diameter for helicopters. • Applicators must use one-half 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 when wind speeds exceed 10 miles per hour at the application site. • DO NOT apply during temperature inversions. SPRAY DRIFT MANAGEMENT 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 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 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 Use the lowest boom height that is compatible with the spray nozzles that will provide uniform coverage. 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. When applying aerially to crops, 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.

19

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 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. Handheld Technology Applications: • Take precautions to minimize spray drift. DRIFT CONTROL ADDITIVES Using product compatible drift control additives can reduce drift potential. When a drift control additive is used, read and carefully observe cautionary statements and all other information on the additive’s label. If using an additive that increases viscosity, ensure that the nozzles and other application equipment will function properly with a viscous spray solution. Preferred drift control additives have been certified by the Chemical Producers and Distributors Association (CPDA).
