1. Submit and/or cite all data required f'ororegistration of your product under FIFRA sec. 3(c) (5) when the Agency requires all registrants of similar products to submit such data; and submit acceptable_responses required for reregistration of yourprcduct under FIFR~ section 4.
2. Make the following label changes: a. Revise the EPA Registration Number to read, "EPA Reg. No. 33270-8". b. On page 13, under the heading "Application Methods", you must include the following spray drift language on your product labeling: E:PA :o!:':n a57~-6 "Avoiding spray drift at the application is the responsibility of the applicator. The interaction of many equipment-and-weather-related factors determined the potential 'for spray drift. The applicator and the grower are responsible for considering all these factors when making decisions."

page 2 EPA Reg. No. 33270-8 In the same section as mentioned above, please incorportate the Lollowing spray drift mangement practices and the aerial drift reduction advisory information to avoid off-target drift movement from aerial applications on your product labeling: "The distance from the outer most nozzles on the boom must not exceed·3/4 the length of the wingspan or rotor." "Nozzles must always point backword parallel with the air stream and never be pointed downwards more than 45 degrees." "Aerial Drift Reduction Advisory Information" Infor.mation on Droplet Size The most effective way to reduce drift potential is to apply large droplets. The best drift strategy is to management strategy to apply the larget droplets that provide sufficient coverage and control. Applying larger droplets reduces drift potential, but will not prevent drift if applications are made improperly, or under unfavorable environmental conditions (see Wind, Temperature and Humidity, and Temperature Inversions) . Controlling Droplet Size Volume - Use 3 high flow rate nozzles to apply the highest practical spray volume. Nozzles with-higher rated flows produce larger droplets. Pressure - Do not exceed the nozzle manufacturer's recommended pressures. For may nozzle types iower pressure produced larger droplets. When higher flow rates are needed, use higher flow rate nozzles instead-of increasing pressure. Number of nozles - Use the minimum number of nozzles that provide uniform coverage. Nozzle Orientation - Orienting nozzles so that the spray is released parallel to the airstream produces larger droplets than other orientations and is the recommended praqtice. Significant deflection from horizontal will reduce droplet size and increase drift potential. Nozzle Type -Use nozzle type that is designed for the intended application. With most nozzle types, narrow stray angles produce larger droplets. ,Consider using low-drift nozzles. Solid stream nozzles oriented straight back produce the largest.droplets and the lowest drift. Boom Length

( page 3 EPA Reg. No. 33270-8 For some use patterns, reducing the effective boom length to less than 3/4 of the wingspan or rotor length may further reduce drift without reducing swath width. Application Height Applications should not be made at a height greater than 10 feet above the top of the largest plants unless a greater height is required for. aircraft safety. Making applications at the lowest height that is safe reduces exposure of droplets to evaporation and wind. Swath Adjustment When applications are made with a crosswind, the swath will be displaced downward. Therefore, on the up and downwind edges of the field, the applicator must compensate for this displacement by adjusting the path of the aircraft upwind. Swath adjustment distance should increased, with increasing drift potential (higher wind, smaller drops, etc). Wind Drift potential is lowest between wind speeds of 2- 10 mph. However, many factors, including droplet size ana equipment type determine drift potential at any given speed. Application should be avoided below 2 mph due to variable wind direction and high inversion potential. NOTE: Local terrain can influence wind patterns. Every applicator should be familiar with local wind pat~erns and how they affect spray drift. Temperature and Humidity When making applications in low relative humidity, set up equipment to produce larger droplets to compensate for evaporation. Droplet evaporation is most severe when conditions are both hot and dry. Temperature Inversions Applications should not occur during a temperature inversion because drift potential is high. Temperature inversions restrict vertical air mixing, which causes small suspended droplets to remain in a concentrated cloud. This cloud can move in unpredictable directions due to the light variable winds common during inversions. Temperature inversions are characterized by increasing temperatures with altitude and are common on nights with limited cloud cover and light to no wind. They begin to form as the sun sets and often continue into the morning. Their presence

page 4 EPA Reg. No. 33270--'8 can be indicated by ground fog; however, if fog is riot present, inversions can also be identified by the movement of smoke from a ground source-: or andaircraf:: smoke generator. Smoke thac. layers and moVes laterall".' in a concentrated cloud (under low wind conditions) indicates an inversion, while smoke that moves upward and rapidly dissipates indicates goed vertical air mixing. Sensitive Areas The pesticide should only be applied wbenthe potential for drift to adjacent sensitiVe areas (e.g, residential areas, bodies of water; cknown habitat for threatened or endanered species, non-target crops) is minimal (e.g. when wind id blowing away from the sensitive areas)." c. On pages 2 and 8, under the heading "Environmental Hazards", you must delete the followig sentence: "This pesticide is toxic to fis!:." Please incorporate t!::te following sentence: "This pesticide is:extremely toxic::o freshwater marine, and estu:::-arir:e fish and aquatic invertebrates including shrimp a:J.doyster." d. On page 14, under the headi:J.g "General Chemigation Directions", there is a tYF:Jgra];:hical error in the firs:: paragraph. Please insert a comrr:a" between "lateral mO;~" and "end tow". 3.

To prevent foaming during filling, keep end of fill pipe below the surface of the liquid in the spray tank. Mixing Order: Fill the spray tank to 1/4 to 1/3 of the total spray volume required. Start agitation. Add different formulation types in the order indicated below, allowing time for complete mixing and dispersion after addition of each product. Allow extra mixing and dispersion time for dry flowable products. Add different formulation types in the following order: Dry flowables (OF); wettable powders 0NP); aqueous suspensions (AS), flowables (F) and liquids (L). Maintain agitation and fill spray tank to 3/4 of total spray volume. Add US Sentry Trifluralin and other emulsifiable concentrates (EC) and any solutions (S). Finish filling the spray tank. Maintain continuous agitation during mixing, final filling. and throughout application. If spraying/agitation must be stopped before the spray tank is empty. the materials may settle to the bottom. Settled materials must be resuspended before spraying is resumed. A sparger agitator is particularly useful for this purpose. Settled material may be more difficult to resuspend than when originally mixed. Precautions: Read and carefully follow all label instructions for each material added to the spray tank. Do not allow water or spray mixture to back-siphon into a water source. Premixing: Dry and flowable formulations may be premixed with water (slurried) and added to the spray tank through a 20 to 35 mesh screen. This procedure assures good initial dispersion of these products in liquid fertilizer or water. Lint? screens in the spray tank should be no finer than 50 mesh (100 mesh is finer than 50 mesh). / Testing for Compatibility in Liquid Fertilizers US Sentry Trifluralin alone or in tank mix combination with dry flowables (OF). wettable powders (WP), aqueous suspensions (AS), flowables (F), liquids (L), or solutions (S) may not combine properly with some liquid fertilizer materials. Small quantities should always be tested before full scale mixing. Follow the testing procedure below to determine if a compatibility agent is needed. If required, use only a phosphate esler-type surfactant designed for use with liquid fertilizers. Such compatibility agents can be mixed at rates as low as 1.5 to 2.0 pints per ton of liquid fertilizer. Add the compatibility agent just before adding pesticides. Testing Procedure

1. Add 1 pint of the liquid fertilizer to a quart jar.
2. Add 1 to 4 teaspoons of the OF, WP, AS, F, or L formulation (depending on mixing ratio required) to the liquid fertilizer. Close the jar and agitate until the materials 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.
3. After dispersing the materials (step 2) add 3 to 4 teaspoons of US Sentry Trifluralin and other EC formulations to the jar and shake well. Add solution herbicides to the mixture last and agitate. Observe the jar for about 10 minutes. If materials rise to the surface and form a thick layer (oily curds) that will not redisperse when agitated, a compatibility agent is needed. If the

US Sentry Trifluralinldraftl09·18/97 Page 13 mixture is easily redispersed with slight agitation, a compatibility agent is not required. Good agitation, however, must be provided to maintain dispersion in the spray tank. 4. If the need for a compatibility agent is demonstrated (step 3) 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 then repeat steps 2 and 3. An effective compatibility agent will cause the mixture to remain uniformly dispersed with little or no separation (oil rising to the surface) for 1/2 hour or longer. If slight separation occurs, 2 to 3 inversions of the jar should be sufficient to uniformly redisperse the mixture. If oily curds form and will not redisperse, additional compatibility agent or an alternative compatibility agent should be tried. Use a clean jar for each test. A compatible mixture will have a uniform appearance and will be relatively easy to redisperse with gentle agitation of the jar. Note: Compliance with state regulations for liquid fertilizer mixing, registration, labeling, and application are the responsibility of the individual andlor company offering the fertilizer or chemical mixture for sale. / Application Methods General As spray volume decreases, the importance of accurate calibration and uniform application increases. Check calibration and uniformity of spray application daily. To avoid spray drift, do not apply when winds are gusting or when wind speed is greater than 15 mph. Ground Broadcast Application Apply US Sentry Trifluralin in 5 to 40 gallons of liquid carrier per acre (broadcast basis), using any properly calibrated, low pressure herbicide sprayer that will apply the spray uniformly. The carrier may be water or liquid fertilizer as specified for the crop to be treated in the "Approved Crops" section of this label. For band application, adjust herbicide rate and spray volume in proportion to the band width and row width treated. Aerial Broadcast Application Apply US Sentry Trifluralin in 5 to 10 gallons of water per acre. Adjust pump pressure, nozzle arrangements, speed, and application height to provide uniform application to the soil surface. Use swath markers or flaggers to assure proper swath width interval. Application with Dry Bulk Fertilizer Dry bulk fertilizers impregnated or coated with US Sentry Trifluralin may be applied as a preplant incorporated treatment on approved crops. All label recommendations for US Sentry Trifluralin regarding application rates, incorporation directions, special instructions, and precautions should be followed. Read and follow alllab~1 instructions below concerning use of US Sentry Trifluralin with dry bulk fertilizer. Properly applied dry bulk fertilizers impregnated with US Sentry Trifluralin provides weed and grass control equal to water sprays. Use the following formula to calculate the amount of US Sentry Trifluralin required to impregnate a ton of dry bulk fertilizer. Pints US Sentry Trifluralin 1000 Per Acre X Pounds Fertilizer Per Acre

Quarts US Sentry Trifluralin . Per Ton of Fertilizer Limitations: Apply a minimum of 200 Iblacre of dry fertilizer impregnated with US Sentry Trifluralin at the recommended broadcast rate per acre. Any commonly used dry fertilizer can be used for impregnation with US Sentry Trifluralin except coated ammonium nitrate and pure

( US Sentry Trifluralinidraft!09-18/97 limestone. These materials will not absorb the herbicide. Blends containing mixtures of these materials can be impregnated. Impregnation: Use any closed drum, belt, ribbon, or other commonly used dry bulk fertilizer blender. Nozzles used to apply US Sentry Trifluralin to dry bulk fertilizer should be placed to provide uniform spray coverage. Application and Incorporation: Spread the fertilizer/chemical mixture with properly calibrated application equipment. Be certain the material is applied uniformly to the soil surface. Dry bulk fertilizer impregnated with US Sentry Trifluralin must be incorporated 2 times. The first incorporation should occur within 24 hours after application. The second incorporation should be delayed a minimum of 5 days after the first and be completed prior to planting. Compliance with State Regulations: Compliance with state regulations relating to dry bulk fertilizer blending, registration, labeling, and application are the responsibility of the individual and/or company offering the fertilizer or chemical mixture for sale. Application by Chemigation US Sentry Trifluralin may be applied through properly equipped chemigation systems for weed control in certain crops as specified in "Approved Crops· section of this label. Read and follow all label instructions outlined below concerning chemigation before applying US Sentry Trifluralin by this method. General Chemigation Directions: Apply this product only through continuously moving center pivot, lateral move end tow, solid set, or hand move irrigation systems, or certain other systems described in EPA-accepted supplemental labeling. . Crop injury, lack of effectiveness, or illegal pesticide residues in the crop can result from nonuniform distribution of chemigation treated water. If you have questions about calibration you should contact state extension specialists, equipment manufacturers, or other experts. Do not connect an irrigation system (including greenhouse systems) used for pesticide application to a public water system. 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. Sprinkler Chemigation Directions: The following directions must be followed for all recommended sprinkler irrigation systems (center pivot, lateral move, or end tow):

1. The 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 back-flow.
2. The pesticide injection pipeline must contain a functional, automatic, quick-closing check valve to prevent the flow of fluid back toward the injection pump.
3. 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.
4. The system must contain functional interlocking controls to automatically shut off the pesticide injection pump when the water pump motor stops.

"'- ( US Sentry Trifluralinldraftl09-18/97 Page 15 5. The irrigation line or water pump must include a functional pressure switch which will stop the water pump motor when the water pressure decreases to the point that pesticide distribution is adversely affected. 6. 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. 7. Do not apply when wind speed favors drift beyond the area intended for treatment. 8. US Sentry Trifluralin should be injected continuously throughout the chemigation period. The chemigation metering pump should be checked periodically during application to insure proper operation. 9. The injection metering pump must be calibrated as specified by the manufacturer. 10. Pesticide injection hoses which connect chemigation metering equipment to the sprinkler irrigation system should be of braided reinforced construction with an internal tube made of nylon, cross-linked polyethylene, or high density polyethylene. 11. US Sentry Trifluralin may cause staining of plastic hoses and tanks. 12. Apply US Sentry Trifluralin in sprinkler irrigation equal to 1/2 to 1 inch of water. 13. During chemigation, maintain agitation in supply tank at all times. Chemigation System Calibration: Sample calculation for use of US Sentry Trifluralin in a chemigation system: • Assume, in this example, 133 acres are to be covered by a chemigation treatment. • Product required, assuming 1.5 pints per acre is 199.5 pints (133 acres X 1.5 ptlacre = 199.5 pt = 25 gallons) • Add 25 gallons of product directly to the injection supply tank. • Adjust the injection system to deliver 25 gallons during the time required to apply 1 inch of water to 133 acres. If the irrigation system requires 20 hours to apply 1 inch of water to 133 acres, the injection rate is 1.25 gallhr and is calculated as follOWS: • 25 gal .;. 20 hr = 1.25 gallhr 1.25 gal/hr = 160 fI ozlhr Proper calibration requires the injection pump to be adjusted to deliver 2.7 fl ozlmin and is calculated as follows: • 160 fl ozlhr .;. 60 min.lhr = 2.7 fl 02 per min. Chemigation Mixing Directions: Undiluted US Sentry TrifluraliA: When used alone, the injection of undiluted US Sentry Trifluralin is recommended in chemigation systems. For undiluted use, the metering pump, supply tank, and any associated equipment must be thoroughly clean and dry before US Sentry Trifluralin is added to the system for injection. ''When injecting undiluted US Sentry Trifluralin, maintain continuous agitation in the supply tank. Diluted US Sentry Trifluralin: US Sentry Trifluralin may be diluted if required to achieve accurate calibration for existing equipment. Partially fill the injection supply tank with a volume of water equal to the amount of US Sentry Trifluralin required (Do not add water to US Sentry Trifluralin). Start agitation. Add the required amount of US Sentry Trifluralin to water in the supply tank and continue mixing while filling the tank to the final volume required by the injection pump calibration. When injecting diluted US Sentry Trifluralin, maintain continuous agitation in supply tank. Application Timing

US Sentry Trifluralinidraftl09-18/97 Page 16 ~pring Application Apply and incorporate US Sentry Trifluralin any time after January 1 when soil can be worked and is in a condition which allows thorough mixing to insure uniform incorporation. See "Approved Crops" section for application timing recommendations for specific crops. Fall Application Fall application can be used for all crops for which US Sentry Trifluralin is recommended as a preplant incorporated treatment. Refer to "Approved Crops" section for any crop specific fall application instructions. In the states of California, North Dakota, South Dakota and Minnesota, apply and incorporate US Sentry Trifluralin any time between September 1 and December 31. In all other states, fall apply US Sentry Trifluralin between October 15 and December 31. Ground may be bedded up over winter. On bedded ground, reduce beds to desired height before planting, by moving some treated soil from beds into furrows. Where soil is left flat over winter, care should be taken not to turn up untreated soil during spring bedding operations. Destroy established weeds during seedbed preparation. Weeds established in furrows as a result of exposing untreated soil should be destroyed before planting. Fall application of US Sentry Trifluralin is not recommended on fields which remain wet or are subject to periods of flooding. Preemergence Application Immediately After Planting Apply and incorporate US Sentry Trifluralin immediately after planting and prior to crop germination. Adjust incorporation equipment so as to not disturb planted seed. Refer to the "Approved Crops' section of this label for crop specific instructions. Postemergence and Layby Application Apply and incorporate US Sentry Trifluralin at the recommended rate to the established crop at or before the last cultivation. Required preharvest intervals for treatments with US Sentry Trifluralin for certain crops are specified in the· Approved Crops· section of this label. Crop cover may prevent uniform soil coverage from over-the-top sprays. To avoid this problem, use drop nozzles or directed sprays to achieve uniform soil coverage. / Incorporation Directions Soil Preparation and Incorporation Ground cover or existing weeds, can interfere with uniform soil incorporation of US Sentry Trifluralin. A manageable level of ground cover will allow uniform incorporation into the top 2 to 3 inches of the final seedbed. Ground cover and crop residues, if excessive, should be reduced by appropriate soil tillage prior to application. US Sentry Trifluralin must be incorporated within 24 hours after application unless otherwise specified on supplemental labeling. Non-uniform application may result in erratic weed control or crop injury. With most equipment and methods of application, a second incorporation is required and may occur any time before planting. The second incorporation should be in a different direction, and to avoid bringing untreated soil to the surface, should not be deeper than the first. Note: Two-pass incorporation is required for all special use programs unless otherwise specified. General Soil Conditions: The soil surface should be smooth enough to allow for uniform application and efficient incorporation of US Sentry Trifluralin. Break up clods using tillage equipment prior to application of US Sentry Trifluralin. Apply when soil moisture is sufficient to allow the breakup of large clods and uniform mixing during the incorporation process. Soil compaction and/or non-uniform incorporation may occur if soil is excessively moist.

US Sentry T rifluralinJdraftl09-18197 'i1! Page 17 /-f Ct.!' Incorporation in Bedded Culture: In bedded culture, WS Sentry Trifluralin should be incorporated to a depth of 2 to 3 inches in the final seedbed. Application Prior to Bedding: Apply US Sentry Trifluralin and incorporate 1 time with recommended equipment. The bedding operation serves as the second incorporation. Do not expose untreated soil during post-bedding operations such as planting since removal of treated soil during planting can allow weed germination and establishment in the drill row. Application After Bedding: Knock off beds to planting height before applying US Sentry Trifluralin. Apply and incorporate US Sentry Trifluralin with recommended equipment that will conform to the shape of the bed. Do not expose untreated soil. Cultivation After Planting: Treated crops may be shallowly CUltivated without reducing the weed control activity of US Sentry Trifluralin. Limit depth of cultivation to the zone of treated soil to avoid moving untreated soil to the surface. Exposure of untreated soil may cause loss of weed control. Incorporation Equipment Use incorporation equipment capable of mixing US Sentry Trifluralin uniformly into the top 2 to 3 inches of the final seedbed. Use of inappropriate equipment or improper use of recommended equipment may result in erratic weed control and/or crop injury. Incorporation equipment such as a tandem disc will mix US Sentry Trifluralin approximately half as deep as the equipment is set to operate. For example, a disc set to cut 4 inches deep will mix most of the US Sentry Trifluralin within the top 2 inches of soil. Any recommended incorporation implement may be used alone or in combination with any other recommended implement. Two incorporation passes are required when using the following incorporation implements (for single pass incorporation, refer to soil conditions and equipment listed under Single Pass Incorporation Option below): Tandem Disc: Set equipment to cut 4 to 6 inches deep and operate at 4 to 6 mph. Rolling Cultivator: Set equipment to cut 2 to 4 inches deep and operate at 6 to 8 mph. Bed Conditioner (DO-All): Set equipment to cut 2 to 4 inches deep and operate at 4 to 6 mph. One incorporation pass is adequate in bedded culture, while 2 incorporation passes are required in flat planted culture. The Do-All should be used only on coarse and medium textured soils. Mulch Treader and other similar disc-type implements: Set equipment to cut 3 to 4 inches deep and operate at 5 to 8 mph. Other Equipment: Other implements including the flexible tine-tooth harrow (Flextine or Melroe), are recommended, but only for certain uses defined in the' Approved Crops" section of this label. Conservation Tillage Practices: In reduced or minimum tillage situations, fall or spring application and incorporation of US Sentry Triffuralin may be combined with tillage operations. The first incorporation may utilize equipment such as a tandem disc, combination implement or bedding equipment that provides gobd soil mixing but leaves a maximum amount of crop residue on the soil surface. The second incorporation may be accomplished with tillage equipment that provides uniform soil mixing used in conjunction with no-till planters (See specific recommendations for reduced or conservation tillage situations for cotton and soybeans in the "Approved Crops' section). Single Pass Incorporation Option US Sentry Trifluralin may be incorporated in a single pass if incorporation conditions allow for thorough and uniform mixing into the top 2 to 3 inches of the final seedbed. Thorough and uniform incorporation may be achieved if the soil at the time of incorporation is of good tilth with moderate moisture, and is relatively free of clods and crop residue. The following types of equipment can be used to obtain thorough and uniform soil mixing from a single incorporation pass:

US Sentry Trifluralinidraftl09-18/97 Finishing Disc with disc blades no greater than 22 inches in diameter, spaced no more than 7 1/2 inches apart. Operate at 4 to 6 mph. Best results are obtained when the disc is equipped with harrow, reel, or basket attachments. Field Cultivator: Set equipment to cut 3 to 4 inches deep and operate at a minimum of 5 mph. A field cUltivator is defined as an implement with 3 to 4 rows of sweeps, spaced at intervals of 7 inches or less with sweeps on successive rows staggered so that no scil is left untumed. Chisel points should not be used. Best results are obtained when the field cultivator is equipped with harrow, reel, or basket attachments. Combination Implements: These implements are defined as 2 or more tillage devices combined to operate as a single tillage unit. For example, 2 to 3 rows of field cultivator C- or S-shaped shanks with successive rows of sweeps staggered so that no soil is left unturned, followed by a spike-tooth or flextine harrow, followed by ground driven reel, basket or incorporator wheels. Combination implements should be set to cut 3 to 4 inches deep and operated at a minimum of 6 mph. Two incorporations are recommended under conditions which prevent optimum soil mixing such as excessive surface residue, roughness, high clay content or soil is too wet or too dry. Combination tools can also be composed of 2 rows of wide crown sweeps that overlap so that the roots of all weeds and plants are severed. This should be followed by 2 gangs of rotating spoked wheels that thoroughly mix US Sentry Trifluralin into the top 2 to 3 inches of the final seedbed. P.T.O.-Driven Equipment (tillers, cultivators, hoes): Adjust equipment to incorporate US Sentry Trifluralin into the top 2 to 3 inches of the final seedbed with rotors spaced to provide a clean sweep of the soil. P.T.O. equipment should not be operated more than 4 mph. / Weeds Controlled by US Sentry Trifluralin I Grass Weeds Common Name annual bluegrass barnyardgrass (watergrass) brachiaria (signalgrass) bromegrass (cheatg rass) (downy brome) cheat (chess) crabgrass (large crabgrass) (smooth crabgrass) foxtail (bottlegrass) (bristlegrass) (g iant foxtail) (green foxtail) (foxtail millet) (pigeongrass) (robust foxtail) (yellow foxtail) Scientific Name Poaannua Eehinochloa crus-galli Braehiaria spp. Bromus teetorum Bromus secalinus -oigitaria spp. Setaria spp. guineagrass Panieum maximum (See special instructions for control in sugarcane in the "Approved Crops" section.)

See detailed information for tank mixing in the "General Information" section of this label. / Special Use Programs

1. Cotton - Chemigation US Sentry Trifluralin may be applied through properly equipped chemigation systems for weed control in cotton. Refer to "Application by Chemigation" in the "General Information" section of this label for use directions for chemigation. Do not apply US Sentry Trifluralin through any type of irrigation sysfem unless these directions are carefully followed. Apply US Sentry Trifluralin in overhead sprinkler irrigation equal to 1/2 to 1 inch of water. Planting and application should occur as soon as possible after the last tillage operation. US Sentry Trifluralin must be applied within 2 days after planting prior to crop emergence. US Sentry Trifluralin does not control established weeds. Soil incorporation is not required when US Sentry Trifluralin is applied through chemigation systems. Broadcast Application Rates/Acre for Chemigation Application Where Conventional Tillage Practices are Used: See rates for cotton "US Sentry Trifluralin - Alone" above. Apply at the maximum recommended rate for spring application for each soil texture class to be treated. Cultivation: Soil treated by chemigation with US Sentry Trifluralin may be shallow cultivated without reducing weed control activity. Broadcast Application Rates/Acre for Chemigation Application Where Minimum Tillage Practices are Used: Soil Texture US Sentry Trifluralin (pints) Coarse 1.0 - 3.0 Medium 1.5 - 4.0 Fine 2.0 - 4.0 Use the lower rate in the rate rantle when additional sequential applications of US Sentry Trifluralin are anticipated. Use the higher rate in the rate range when high crop residue levels are present, where dense weed populations are anticipated, or where no additional sequential applications of US Sentry Trifluralin are to be made. Rotational Crop Restrictions • Conventional Tillage: Refer to the rotational crop restrictions in the "General Use Precautions" section of this label. • Minimum Tillage: In addition to the rotational crop restrictions listed in the General Use Precautions section of this label, do not plant grain sorghum in the year following the application of US Sentry T rifluralin.
2. Cotton - Weed Control in Conservation Tillage This section describes application methods and techniques for weed control with US Sentry Trifluralin in conservation tillage cotton. US Sentry Trifluralin may be applied and incorporated in the fall in advance of spring planting, in the spring before planting, after planting prior to crop

Single or multiple applications may be made so long as maximum application rates are not exceeded and rotational crop restrictions are followed. Broadcast Application Rates for Conservatio n Tillage: Soil Texture US Sentry Trifluralin (pints/A) Coarse 1.0 - 2.0 Medium 1.5 - 2.0 Fine 2.0 -4.0 Strip Planting into Small Grain Cover Crops Fall planted cover crops may be utilized to control wind erosion and protect developing crop seedlings from wind damage. Prior to planting cotton, the cover crop may be treated with a contact herbicide to prevent continued growth and development and prevent competition with crop seedlings for water and soil nutrients. The standing cover crop (now dead) continues to control wind erosion and provide protection to the developing crop until it is well established. Strip Planting: In strip planting, cotton is seeded into competition-free bands established in the cover crop. Competition-free bands may be established by leaving unseeded drill rows when seeding the cover crop, by tillage, or by use of a contact herbicide to prepare competition-free bands prior to planting. Fall Application Before Establishing a Cover Crop Small grain cover crops (wheat, barley or rye) may be established following a preplant incorporated application of US Sentry Trifluralin. Apply US Sentry Trifluralin to flat ground at a broadcast rate of 2.0 to 3.0 pints per acre and incorporate once within 24 hours using incorporation implements that can be set to cut no more than 2 to 3 inches deep, such as a springtooth harrow. Do not incorporate with a tandem disc. Form beds with disc bedders or other bedding implements that will mix and move most of the treated soil from the furrows to the beds. Phosphate and other fertilizer may be applied as appropriate during incorporation operations. Plant 2 to 4 rows of the small grain cover crop 2 inches deep in the furrows between the beds. To avoid injury to small grain seedlings, place seed below the treated layer of soil. Sarley is usually less susceptible to injury than wheat or rye. Soil moisture must be adequate to establish and maintain the cover crop. In late winter (February), apply 2,4-0 if necessary for broadleaf weed control. Spring Application Before or After Planting (Within Competition-Free Bands) Apply US Sentry Trifluralin using low pressure ground equipment as a band (within the weed free zone) or as a broadcast treatment. Application and incorporation may occur before planting or after planting prior to crop emergence. If applied after planting, set incorporation equipment so as to not disturb the planted seed (~ee incorporation instructions). Incorporation: Equipment should be adapted to the width of the competition-free band. Use equipment that will uniformly mix US Sentry Trifluralin into the weed germination zone. Weed control resulting from single pass incorporation or with incorporation equipment that does not result in thorough mixing of soil treated with US Sentry Trifluralin may be reduced compared to conventional double pass incorporation. Implements used to incorporate US Sentry Trifluralin after planting should be operated so that they do not disturb the planted seed or growing crop. Use the lower rate in the rate range when additional sequential applications of US Sentry Trifluralin are anticipated. Use the higher rate in the rate range where high crop residues are present, and where dense weed populations are anticipated. For band treatments, reduce the application rate in proportion to the row spacing and band width treated. For example, treating a 12-inch band where the row spacing is 36 inches would require 1/3 of the recommended broadcast rate per acre (12 inches divided by 36 inches = 1/3). Layby Applications

US Sentry Trifluralin/draW09-18/97 Page 31 Layby applications may be made in established cotton from the 4 true leaf stage of growth up to layby, but not less than 90 days before harvest. Apply US Sentry Trifluralin uniformly to the soil surface using drop nozzles if necessary. Soil incorporate using 1 pass of a sweep-type CUltivator or properly adjusted rolling cultivator. Operate CUltivation equipment at speeds sufficient to provide vigorous soil mixing and exercise care to avoid mechanical injury to the crop.

Special Precautions for Use of US Sentry Trifluralin on Small Grains Carefully follow directions for use of US Sentry Trifluralin on small grains to minimize potential crop stress. Under certain conditions, delayed crop emergence and or stand reduction may occur when US Sentry Trifluralin is applied to barley, durum, or wheat. The combined effect of certain cultural practices and unfavorable soil or environmental conditions may cause excessive crop seedling stress resulting in retarded crop growth, stand reduction, and possibly reduced yield. For best results, observe the following cultural practices or precautions: Use tillage methods that provide a uniformly firm seedbed and time tillage operations to conserve moisture. Irrigate prior to planting or after germination and emergence. Moisture received between planting and emergence may cause crusting, especially on loose seedbeds.

US Sentry Trifluralinidraftl09-18/97 Page 44 Do not exceed recommended application rates for US Sentry Trifluralin. This is particularly important on coarse textured or low organic matter soils. Carefully follow incorporation directions. When applying preplant incorporated treatments, operate equipment at recommended depth and speed to place US Sentry Trifluralin into the upper 1 to 1 1/2 inches of soil. If applied after planting, set equipment so as to not disturb planted seed. Set drills to place seed at a the depth specified in use directions. A planting depth greater than 2 1/2 inches for spring wheat or durum will result in increased seedling stress 1:ind decreased emergence. Use only high quality seed where US Sentry Trifluralin is to be applied (avoid use of small seed with low starch reserves). If seed treatments are used, apply at the correct rate and uniformly across all seeds. Misapplication may result in reduced germination and/or seedling vigor. Avoid use of seed varieties known to have poor seedling (emergence) vigor. Soil characteristics and environmental conditions which may contribute to crop seedling stress that may be accentuated by use of US Sentry Trifluralin include: Soil related: High salinity, eroded knolls/hilltops, loose dry soils and compaction. Weather related: Cold and/or wet soils, excessively hot soils, excessive moisture, drought, and soil crusting from heavy rainfall.
