USER SAFETY RECOMMENDATIONS USERS SHOULD: Wash himds before eating, drinking, chewing gum, using tobacco or using the toilet ENVIRONMENTAL HAZARDS Do not apply directly to water, or to areas where surface water is present, or to intertidal areas below the mean high water mark. Do not contaminate water by cleaning of equipment or disposal of wastes- Metribuzin is a chemical which can travel (seep or leach) through soil and can contaminate ground water which may be used as drinking water. Metribuzin has been found in ground water as a result of agriCUltural use. Users are advised not to apply metribuzin where the water table (ground water) is close to the surface and where the soils are very permeable, i.e., well drained soils such as loamy sands. Your local agricultural agencies can provide further information on the type of soil in your area and the location of ground water. CAREFULLY OPEN THE OUTER BARRIER BAG AND IMMEDIATELY DROP THE INNER PACKET INTO THE SPRAY TANK. DO NOT OPEN THE INNER PACKET OR EXCESSIVELY HANDLE THE INNER PACKET. MOISTURE WILL CAUSE BREAKAGE.

Observe all cautions and limitations on labels of all products used in mixrures. 2 USE RATES All LEXONE SP rates in this label are expressed as broadcast rates in pounds or ounces product per acre; for band treatmen~ use proponionately less. For example, for a 14" band on a 42" row, use 113 of Ihe broadcast rates given in Ihis label. When a range of rates is given, use the lower rates on coarse-texrured soils (low in clay or organic matter) and the higher rates on fine­ textured soils (high in clay or organic matter). Use rates of "Lexone" SP are expressed as pounds of formu­ lated product per acre. ''Lexone'' SP is premeasured in I pound water soluble packets, 5 packets per bag. Add whole packets only. DO NOT attempt to open the water soluble packets.

These crops are asparagus, com, potatoes, soybeans, and sugarcane. With suffi­ cient moisture, LEXONE SP continues to control weeds as Ihe crop becomes better able to compete. If a significant number of weed seedlings begin to break Ihrough Ihe preemergence treatment, secondary weed control procedures, including cultiva­ tion and postemergence herbicide application, should be imple­ mented. The degree of weed control and duration of effect vruy wilh Ihe following: Organic matter content of soil-Soils wilh high organic matter require higher application rates !han soils wilh low organic matter for equivalent herbicide performance. Soil texture-Soils with high clay content require higher appli­ cation rates than soils with lower clay content Soil pH-LEXONE SP activity increases as soil pH increases. Rainfall-Moisture is necessruy to activate the herbicide. The best results are obtained if soil is moist at application and addi-

tiona! moisture is supplied by rainfall or sprinkler irrigation (1/4 to 1I2'~ within I week after application. If moisture is insufficient to activate the herbicide, a -shallow cultivation (preferably by rotary hoe) should be made after the crop emerges and while weeds are small enough to be controlled by mechanical means. If heavy rains occur within 3 weeks of planting, crop in jury may resul~ after 3 weeks, effects are likely to be negligible. Amount applied-On a given soil, applying the higher recom­ mended rate produces greater results than applying the lower recommended rate. Other conditions-Factors such as incorporation depth of LEXONE SP, competitionoftl1e crop with weeds, weed species, drought stress of weeds, high salt content of soil, crop seed quality, soil residues of previously applied herbicides, soil insecticides, and combination herbicide treatments all can affect perfoimance. Postemergence Applica/iQn (Emerged Seedling Weedr) LEXONE SP can be applied over the top of certain crops to effectively control susceptible emerged seedling weeds. These crops are alfalfa (established, dormant), potatoes, sainfoin (dormant), sugarcane, and tomatoes (seeded and transplants). LEXONE SP should be applied when weeds are young, healthy, and growing actively. Weed control may not be apparent for 2 to 4 weeks after application; under very' dry conditions, weed control may not be apparent for 4 to 6 weeks. Adequate moisture (I12'~ is needed within 2 to 3 weeks after application to move LEXONE SP into the weed root zone. Lack of adequate moisture after application may result in poor weed control. Control or suppression of the weeds listed in this label depends on weed size. Making applications to broadleaf weeds taller than I" or grasses having more than 2 leaves may result in poor control. Directed postemergence applications of LEX ONE SP, in which spray nozzles are adjusted so that weeds are sprayed but the crop is no~ can be used on emerged soybeans (AL, AR, FL, GA, LA, MO, MS, NC & OK) and established tomatoes to control suscep­ tible emerged seedling weeds. Results of postemergence treatment of emerged seedling weeds vary with use rates and environmental conditions. The best results are obtained on succulent weeds growing in humid, warm weather. Adding a surfactant to the spray mixture (when recom­ mended) increases contact effects of LEXONE SP. Postemergence application also controls susceptible emerging seedling weeds for an extended time. WEEDS CONTROLLED LEXONE SP effectively controls the following weeds when used alone according to label directions. Additional weed control results when LEXONE SP is used in combination with other herbicides in tank mixes. See product labels of other herbicides to determine which weeds they control.

• controlled with LEXONE SP at !'ales above O.661b per' acre I partial cortlrOl APPLICATION INFORMATION SPRAY APPLICATION Spray Preparation Spray Tank Cleanup Spray equipment must be clean and free of previous pesticide deposits before applying LEXONE SP and properly cleaned out after applying this herbicide. Prior to applying LEXONE SP, clean the spray tank following the procedures described on the label of the product used previously. Immediately following applications of LEXONE SP, thoroughly clean all mixing and spray equipment according to the following instructions. I. Drain tank; thoroughly hose down the interior swfaces of the tank; then flush tank, boom, and hoses with clean water for a minimum of 5 minutes. Loosen and physically remove any visible deposits.

2. Fill the spray tank with clean water and add a heavy-duty detergent at the rate of one cup per 20 gallons of water. Hush the cleaning solution through the boom, hoses, and nozzles. Add more water to completely fill the tank and allow to agitate/recirculate for at least 15 minutes. Again, flush the hoses, boom, and nozzles with the cleaning solution, then drain the tank.
3. Repeat step 2.
4. Clean the nozzles and screens.
5. Thoroughly rinse the tank with clean water for a minimum of 5 minutes, flushing the water through the hoses and boom.
6. All rinse water must be disposed of in compliance with local, State, and Federal guideline. Mixing in Water I. Calculate the number of LEXONE SP packets required.
7. Fill the spray tank 114 full of water.
8. Star! the agitation system. Add the required number of LEXONE SP soluble packets. Allow the packets to dissolve and the chemical to fully disperse before adding other pesticides or spray adjuvants. Continue agitation. NOTE: To add LEXONE SP packets, open the outer barrier bag and drop the inner soluble packet directly in to water. The barrier bag is NOT soluble in water. DO NOT place in spray tank. At anyone time, open only those bags which will be used immediately.
9. Add any additional tank mix components one at a time while continuing to add water 4 :- When using tank mix components for the first time, it is a good idea to check their compatibility in a 'Jar test" before mixing in the spray tank.

• Any component that does not mix in well in the spray tank should be premixed with two parts water before being added to the spray tank.
• Always premix Treflan' (or trifluralin containing products) or Prowl' with water before adding to the spray tank.
• Add any surfactant last, when the tank is nearly full.

5. Continue agitation throughout preparation; agitation is required for uniform mixing and application.
6. Apply spray preparation promptly. Do not store tank mixes of LEXONE SP with ''Treflan'' or "Prowl" overnight
7. Hush sprayer with water after use and dispose of rinsate properly. NOTE: Do not use ''Lexone'' SP when liquid fertilizer solutions or suspensions are intended to be the carrier. ''Lexone'' SP is intended to be used only when water is the carrier. Liquid fertilizer solutions or suspensions may be added as spray additives, but should not exceed 10% of the total finished spray volume. Fertilizers must be the last components added to the tank, after the ''Lexone'' SP has fully dispersed. Application (Also see Spray Drift Management) Ground Apply LEXONE SP spray preparation with a properly calibrated low pressure (20 to 40 psi) boom sprayer equipped with fan-type nozzles and screens no finer than 50 mesh-Continuous agitation in the spray tank is required to keep the material suspended. To avoid crop irijwy, avoid overlapping, and shut off spray booms while starting, turning, slowing, or stopping. Use 10 to 40 gal of water per acre; when using tankmixes refer to label of the tank mix partners. Aerial Apply unifonnly with aerial equipment Continuous agitation in the spray tank is required to keep the material suspended. Avoid overlapping. Do not apply under conditions that favor drift. See Spray Drift Management Use 2 to 10 gal per acre, except "as follows:

• For sugarcane (irrigated only) in Hawaii, use 7 gal per acre.
• For sugarcane in Horida, Louisiana and Texas, use 5 to 10 gal per acre.
• For potatoes west of the Rocky Mountains, use 5 to 10 gal per acre. CHEMIGATION (POTATOES ONLy] Apply this product only through sprinkler irrigation systems (including center pivot, linear, solid set, and wheel roll). Do not apply this product through any other Iype of irrigation system. Crop injury, lack of effectiveness, or illegal pesticide residues in the crop can result from nonuniformdistribution of treated water. If you have questions about calibration, you should contact State Extension Service specialiSts, equipment manufacturers, or other experts.

irrigiIlWn System Requirements The irrigation system must contain the following: a functional check valve. vacuum relief valve. a low-pressure drain (to prevent contamination of the water sowce from backflow; should be located on the irrigation pipeline). functional interlocking controls (to shut off the pesticide injection pump automatically when the water pump motor stops). • a metering pump, such as a positive displacement injection pump (e.g., diaphragm pump) designed and constructed of materials that are compatible with pesticides and capable of being fitted with a system interlock. The pesticide injection pipeline must contain the following: • a functional, automatic, quick-closing check valve (to prevent the flow of fluid back toward the injection pump). • a functional, solenoid-operated valve (normally closed) located on the intake side of the injection pump (should be connected to the system interlock to prevent fluid from being withdrawn from the supply tank when the irrigation system is shut down either automatically or manually). The irrigation line or water pump must include a functional pressure switch that will stop the water pump molor when pesticide distribution is adversely affected by a decrease in water pressure. Clremigation Precautions Distributing treated water unevenly can result in crop injury, lack of herbicide effectiveness, or pesticide residues that are over tolerance. To ensure that the mixture is applied evenly at the recommended rate, use sufficient water and apply the mixture for the proper length of time. Do not permit runoff during chemigation. Do not apply when wind speed favors drift beyond the area intended for treatment ChemigiIlWn Systems Connected to Public Water Systems A "public water system" is defined as 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 2S individuals daily at least 60 days out of the year. Chemigation systems connected to public water systems must contain the following: 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 alter­ native to the RPZ, the water from the public water system should be discharged into a reservoir tank prior to pesticide introduction. a complete physical break (air gap) between the outlet end of the fill pipe and the top or overflow rim of the reservoir tank of at least twice the inside~ diameter of the fill pipe. a functionai, automatic, quick-closing check valve in the pestiCide injection pipeline to prevent the flow of fluid back toward the injection pump. a functional, solenoid-operated valve (normally closed) located on the intake side of the injection pump (should be connected to the system interlock to prevent fluid from being withdrawn 5 from the supply tank when the irrigation system is shut down either automatically or manually). • functional intetlocking controls to automatic;!lly 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. Systems must use a metering pump, such as a positive displace­ ment 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. Application See Spray Application for mixing, agitation, and application instructions. For application rate information, see Potatoes under Specific Crop Uses.

" ' ,.,:;om?::.?;... .... ~ FALLOW Corn or Tomotoes -Fall Bedded Fields in California (OnIy) Apply 0.66 to 1.0 Ib LEXONE SP per acre in the fall. Use the lower rates on soils contaIning 0.5 to 2% organic matter and the higher rates on soIls containing greater than 2% organic matter. To prevent crop injury, do not plant corn within 120 days of applIcation or tomatoes within 90 days of application. At least 2" of mOIsture IS needed to acUvate LEXONE SP for weed control and to begm breakdown of the herbicide in soil for crop safety. Do not disturb the soil surface after applicauOn-doing so reduces weed control. Whear (Reduced Tillage F aikJw) LEXONE SP may be applied for weed control during the fallow period after wheat harvest or in the spring before winter wheat is planted. Winter wheat can be seeded 4 months (120 days) after spring application. Mechanical iillage or applicanon of a contaCt herbiCide may be reqUIred to control weed germination prior to seeding of winter wheal Best results are obtained when straw and chaff are evenly distributed across the field.

Apply 0.5 to 0.751b LEXONE SP per acre as an after-harvest treatment prior to subsequent planting of winter wheat !he following year. Use the lower rate on coarse-textured soils and the higher rate on medium-to fine-textured soils. Use higher rates for longer weed control or for weeds requiring higher rates for control. For best results. apply before weeds emerge. One-half inch or more of rainfall is necessary to activate !he herbicide. See Weeds Controlled for a listing of weeds controlled or suppressed in fallow. If weeds are larger than 2" tall or across. or weeds other than those listed on the label are presen~ use a suitable registered companion herbicide such as DuPont FINESSE" Herbicide, Grarnoxone' Extra, or "Roundup" in a tank mix with LEXONE SP. Refer to companion product labeling for additional use instructions and precautions. 7 PEAS AND LENTILS Preemergence and postemergence application of LEXONE SP is recommended for suppression of certain braadleaf weeds in lentils and certain peas, including green peas, dry peas, and Austrian winter peas. For weed suppression in chick peas, only preemergence applications of LEXONE SP are recommended. For weed suppression in Austrian winter peas, only postemer­ gence applications of LEXONE SP are recommended. LEXONE SP suppresses common chickweed, common groundsel, henbi~ lambsquarter, chamomile mayweed, field pennycress, prostrate pigweed, redroot pigweed, pineappleweed, shepherd's purse, and Pennsylvania smartweed. Weed suppres­ sion is a visual reduction in weed competition (reduced popula­ tion andlor size and vigor compared to an untreated area). Degree of suppression varies with rate used, size of weeds at application. and environmental conditions before, during, and after treatment. For common chickweed, henbi~ and shepherd's purse, best results are obtained from preemergence application. Preemergence Application to Lentils, Green Peas, Dry Peas, and Chick Peas Apply 033 to 0.50 lb LEXONE SP per acre as a broadcast appli­ cation in !O to 40 gal of water with ground spray equipment after planting but before crop germinates. Crop should be planted 2" deep. Use the higher rate on fine-textured soils (high in clay or organic mauer) or when a history of high weed populations exists. LEXONE SP must be thoroughly incorporated into the soil either by rainfall or mechanical means before weeds germinate and become established_ To incorporate LEXONE SP mechani­ cally, use a spike harrow or similar shallow incorporation equipment set to mix the top I" to 2" of soil. After the initial incorporation tillage, cross-harrow to ensure uniform soil mixing. Mechanical incorporation is important when soil conditions are dry. If soil is moist at application and rain follows before weeds emerge, weed control should be adequate without supplemental incorporation. Postemergence ApplicatWn to Lentils, Green Peas, Dry Peas, andAuslrilln Winter p,eas Apply 0.2 to 033 lb LEXONE SP per acre as a broadcast appli­ cation in 20 to 40 gal of water with ground spray equipment. Make the application when the crop is 2" to 6" tall and weeds are less than 2" tailor across. Use the higher rate on fine-textured soils (high in clay or organic mauer). During application, maintain continuous agitation in the spray tank to keep product in suspension. To avoid crop injury. do not overlap spray swaths and shut off booms while ttlrning, slowing, or stopping. Note: Treatment may cause some chlorosis (yellowing of leaves) or minor necrosis (burning of leaves characterized by brown tissue at outer margin). Symptoms are most severe when LEXONE SP is applied to wet foliage andlor wet soils.

Do not exceed 0.33 Ib per acre per application on coarse-textured solis containing 05 to 1.0% organic matter. ApplicaiWn by ChemigaiWn Before applying LEXONE SP by sprinkler irrigation, read the ehemigation section in this labeL Apply at the specified rate in 0.25 to 0.75" of water per acre (0.25 to 050" of water per acre on sandy soil). In center pivot and self­ propelled Wheel-move systems, apply as a continuous injection; in set-in, permanent, solid-set sprinkler systems apply the herbicide in such a manner that 0.25 to OS' of water follow the herbicide application. Irrigation systems must be equipped with automatic shutoff devices that prevent backflow to the water source. Maintain continuous agitation in injection nurse tanks during application.

Directed postemergence application to soybeans may be made only under the conditions discussed in the Postemergence to Soybeans section of this label. LEXONE SP can be used alone or in combination with another herbicide. Combination treatments control not only weeds that are susceptible to LEXONE SP but also weeds that are suscep­ tible to the companion herbicide(s). DuPont recommends using one or more of the following herbicides either before applying LEXONE SP or in a tank mix combination. "Treflan" (or other registered soybean products that contain trifluraJin as the sole active ingredient) Sonalan' "Lasso" (or other registered soybean products that contain alachlor as the sole active ingredient) "Roundup" Bronco~ • 'DuaI" "Prowl' • Frontier' Freedom"" (or other registered soybean products that contain alachlor and triflurnlin as the sole active ingredients) Command' Commences "Gramoxone" Extra (or other registered soybean products containing paraquat as the sole active ingredient) Preemergence to Soybeans Prepkznt incorporation of a LEXONE SP tankmix

• see Rote Table 1 For improved weed control, use a combination of LEX ONE SP and one of the herbicides listed below. Consult the companion herbicide labels for rates and use directions. Follow the most restrictive labeling of the tank mix herbicides involved. • "Treflan", "Dual", or "Sonalan" - apply within 14 days of planting • "Lasso" or "Prowl" - apply within 7 days of planting Select the appropriate LEXONESP rate from Rate Table 1. For light infestations and applications closer to planting, use the lower rate. For heavy infestations and applications further from planting, use the higher rate. Mix the LEXONE SP and tankmix partner in water and incorporate into the soil before planting soybeans. Improper soil incorporation can result in erratic weed control or crop injury. Do not plant seeds more than 2" deep. Preemergence application of LEXONE SP in a tankmix or preceded by prepkznt incorporation of a companion herbicide • See Rote Table 1 • Apply LEXONE SP or LEXONE SP tankmix before soybeans emerge, otherwise severe crop injury may occur • To avoid crop injury, plant seed 1·112 to 2" deep on Oat or raised seedbeds.

• See Rate Table 2 For broadleaf weed control in soybeans. DuPont recommends reduced rates of LEXONE SP either preplant, preplant incorpo­ rated, or preemergence followed by a postemergence application of DuPont CLASSIC, SYNCHRONY STS, RELIANCE STS or PINNACLE herbicides. For grass weed control, LEXONE SP can be applied in a tank mix with, or as a sequential overlay after, ''"Treflan'', "Dual", '"Sonalan", "Lasso", "Prowl", or "Frontier'. Alternatively, a soil application of LEXONE DF may be followed by a postemer­ gence grass herbicide stich as ASSURE II. Follow the instruc­ tions on the producllabels. Selecl the appropriate LEXONE SP reduced rate from Rate Table

2. Apply preplant, preplanl incorporated or preemergence as directed. Follow with a postemergence application of DuPont CLASSIC, SYNCHRONY STS, RELIANCE STS or PINNACLE herbicides when weeds are small and actively growing (usually 14-28 days after planting). Preplant or Preemergence to Soybeans in Conservation TiUage When soybeans will be planted directly into a preformed bed (stale seedbed), cover crop, or in previous crop residues such as com or small grain stubble, LEXONE SP tankmixes may be used for bumdown or suppression of annual broadleaf weeds and grasses and some perennials. LEXONE DF plus crop oil concen­ trate (COC) or nonionic surfactant (NIS) will control or bum off most small weeds ($ I"). For improved burndown of existing broadJeaf weeds and grasses, LEXONE SP may be tonkmixed with "Gramoxone" Extra, "Roundup", "Bronco", or 2,4D (LVE). For LEXONE SP + "Gramoxone" Extra tankmix applications, use 20-60 gallons of water per acre, using the higher rate for dense stubble or vegetation. For LEXONE SP + "Roundup"f"Bronco" applications, use 20 gallons of water per acre. Use nonionic surfactant or COC in any application where bumdown of existing vegetation is desired according to recom­ mendations on companion product label. When using 2,4-D (L VE) in a tankmix with LEXONE SP, follow the minimum preplant intervals and directions for use listed below. 7 days for 0.5 pI per acre 2,4-D (3.8 Ibfgal L VE) or 0.24 Ib acid equivalents per acre. 30 days for 1.0 pt per acre 2,4-D (3.8 Iblgal L VE) or 0.48 Ib acid equivalents per acre. Regardless of the rate of2,4-D used, make only one applica­ tion per growing season. Use a minimum of IO gal total spray volume per acre with ground equipment, or a minimum of 5 gal total spray per acre with aerial equipment When 2,4-D is applied, do not feed hay, forage or fodder. Restrict livestock from grazing treated fields or cover crops treated for bumdown. • Refer to the 2,4-D label for precautionary statements and use instructions. Read the crop injury statements on the 2,4-D (L VE) herbicide label and use only if these statements are acceptable. For improved residual control of specific grasses or broadleaf weeds, LEXONE SP may be tankmixed with one or more of the products listed at the beginning of the soybean section of this label. Postemergence to Soybeans LEXONE Sf' may be applied as a directed postemergence treatment in the states of AI., AR, FL, GA, LA, MO, MS, NC, OK according to the use direction below. DO NOT SPRAY LEXONE SP OVER THE TOP OF SOYBEANS. Apply when soybeans are at least 12" tall and when broadleaf weeds do not exceed 3 and grasses and common ragweeds do not exceed I" in height Direct the spray to cover weeds with minimal or no contact to the soybean plant Crop injury may result if the spray is higher than 2" on the soybean stem. 10 Add a nonionic surfactant at 112 pt per 100 gal spray solution. Apply 0.33 to O.66lb per acre in25 to 40 gal of water. Use the lower rate for seedling weeds and the higher rate for larger weeds. • Application of 0.33 lb per acre controls Rorida beggarweed, carpetweed, cocklebur, daytlower, Mexican weed, prostrate and smooth pigweed, redroot pigweed (carelessweed)*, common purslane, sieklepod (Cassia), velvetleaf, and crabgrass (large, smooth). Application of 0.33 to 0.66 Ib per acre controls hemp sesbania, prickly sida (spiny sida, leaweed). • Application of 0.66 Ib per aCre controls jimsonweed, Pennsylvania smartweed, and common ragweed. It also gives partial control of momingglories, horsenettle, Rorida purslane (Aorida pusley), spotted spurge, and wild poinsettia when weeds are less than 3" tall and of broadlcaf signalgrass . up to I" tall. "'except triazine-resistant weeds If needed, a second application may be made after 7 days. Do not exceed nozzle pressure of 25 psi or use nozzle tips smaller than 8002 T-jet (or equiValent). . For post-directed broadcast application, use a single flood-type spray nozzle ("K" series or equivalent) per middle, mounted on an oiling shoe or gauge wheel. For a post-directed band treatmen~ use two nozzles per row, mounted on oiling shoes or gauge wheels (one on each side of the row).

SPRAY DRIFT MANAGEMENT The interaction of many equipment and weather-related factors determines the potential for spray drift The applicator is respon­ sible for considering all these factors when making application decisions_ AVOIDING SPRAY DRIfT IS THE RESPONSIBILITY OF THE APPUCATOR. IMPORTANCE OF DROPLET SIZE The most effective way to reduce drift potential is to apply large droplets (> 150 - 200 microns).-The best drift management strategy is to apply the largest droplets that provide sufficient coverage and control. The presence of sensitive species nearby, the environmental conditions, and pest pressure may affect how an applicator balances drift control and coverage. APPLYING LARGER DROPLETS REDUCES DRIfT POTENTIAL, BUT WILL NOT PREVENT DRIfT IF APPUCATIONS ARE MADE IMPROPERLY OR UNDER UNFAVORABLE ENVI­ RONMENT AL CONDmONS! See Wind, Temperature and Humidity, and Temperature Inversions sections of this label. Controlling Droplet Size - General Techniques • Volume - Use high flow rate nozzles to apply the higbest practical spray volume. Nozzles with higher rated flows produce larger droplets. • Pressure - Use the lower spray pressures recommended for the nozzle. Higher pressure reduces droplet size and does not improve canopy penetration. WHEN HIGHER FLOW RATES ARE NEEDED, USE A HIGHER-CAPACITY NOZZLE INSTEAD OF INCREASING PRESSURR • Nozzle Type - Use a nozzle type that is designed for the intended application. With most nozzle types, narrower spray angles produce larger droplets. Consider using low-drift nozzles. Controlling Droplet Size - Aircraft • Number of Nozzles - Use the minimum nurober of nozzles with the highest flow rate that provide uniform coverage. • Nozzle Orientation - Orienting nozzles so that the spray is emitted backwards, parallel to the airstream will produce larger droplets than other orientations. • Nozzle Type - Solid stream nozzles (such as disc and core with swirl plate removed) oriented straight back produce larger droplets than other nozzle types. • Boom Length - The boom length should not exceed 314 of the wing or rotor length - longer booms increase drift potential. • Application Height - Application more than lOft above the canopy increases the potential for spray drift BOOM HEIGHT Setting the boom at the lowest labeled height (if specified) which provides uniform coverage reduces the exposure of droplets to evaporation and wind. For ground equipmen~ the boom should remain level with the crop and have minimal bounce. WIND Drift potential increases at wind speeds of less lIIan 3 mph (due to inversion potential) or more lIIan 10 mph. However, many factors, including droplet size and equipment type determine drift potential at any given wind speed. AVOID GUSTY OR WINDLESS CONDmONS. Note: Local terrain can influence wind patterns. EveI)' appli­ cator should be familiar with local wind patterns and how they affect spray drift TEMPERATURE AND HUMIDITY When making applications in hot and dl)' conditions, set up equipment to produce larger droplets to reduce effects of evapo­ ration. TEMPERATURE INVERSIONS Drift potential is high during a temperature inversion. Temperature inversions restrict vertical air mixing, which causes small suspended droplets to remain close to the ground and move laterally in a concentrated cloud. Temperature inversions are characterized by increasing temperature with altirude and are common on nights with limited cloud cover and light to no wind. They begin to form as lIIe sun sets and often continue into the morning. Their presence can be indicated by ground fog; however, if fog is not presen~ inversions can also be identified 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 lIIat moves upward and rapidly dissipates indicates good vertical air mixing. SHIELDED SPRAYERS 15 Shielding lIIe boom or individual nozzles can reduce the effects of wind. However, it is the responsibility of the applicator to verify that the shields are preventing drift and not interfering with uniform deposition of the product AIR ASSISTED (AIR BLAST) FIELD CROP SPRAYERS Air assisted field crop sprayers carry droplets to the target via a downward directed air stream. Some may reduce the potential for drift, but if a sprayer is unsuitable for the application and/or set up improperly, high drift potential can result It is the respon­ sibility of lIIe applicator to determine that a sprayer is suitable for the intended application, is configured properly, and IIIat drift is not occurring. Note: Air assisted field sprayers can affect product performance by affecting spray coverage and canopy penetration. Consult the application equipment section of this label to determine if use of an air assisted sprayer is recommended. . RESISTANCE When herbicides willi lIIe same mode of action are used repeat­ edly over several years to controlllle same weed species in the same field, naturally-occurring resistant weed biotypes may survive a correctly applied herbicide treatment, propagate, and become dominant in lIIat field. These resistant weed biotypes may not be adequately controlled. Cultural practices such as tillage, preventing weed escapes from going to seed, and using herbicides with different modes of action within and between crop seasons can aid in delaying the proliferation and possible dominance of herbicide resistant weed biotypes.
