-3- Follow manufacturer's instructions for cleaning/maintaining PPE. If no such instructions for washables, use detergent and hot water. Keep and wash PPE separately from other laundry. Engineering Control Statements When handlers use closed systems, enclosed cabs, or aircraft in a manner that meets the requirements listed in the Worker Protection Standard (WPS) for agricultural pesticides [40 CFR 170.240(d)(4-6)], the-handler PPE requirements may be reduced or modified as specified in the WPS. User Safety Recommendations Users should: • Wash hands before eating, drinking, chewing gum, using tobacco, or using -the toilet. • Remove clothing immediately if pesticide gets inside. Then wash thoroughly and put on clean clothing. • Remove PPE immediately after handling this product. Wash the outside of gloves before removing. As soon as possible, wash thoroughly and change into clean clothing. Environmental Hazards Do not contaminate water when disposing of equipment wash water. 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 allow this material to drift onto neighboring crops or noncrop areas or use in a manner or at a time other than in accordance with label directions because animal, plant or crop injury, illegal residues, or other undesirable results may occur. Norflurazon can contaminate surface water through spray drift. Under some conditions, norflurazon may also have a high potential for runoff into surface water (primarily via dissolution in runoff water) for several months post-application. These include poorly draining or wet soils with readily visible slopes toward adjacent surface waters, frequently flooded areas, areas over-laying extremely shallow ground water, areas with in-field canals or ditches that drain to surface water, areas not separated from adjacent surface waters with vegetated filter strips, and areas overlaying tile drainage systems that drain to surface water. This chemical is known to leach through soil into ground water under certain conditions as a result of agricultural use. Use of this chemical in areas where soils are permeable, particularly where the water table is shallow, may result in ground water contamination.

1. Do not apply this product through any type of irrigation system.
2. Follow directions for each geographic region, soil type, and crop. Applications in geographic regions not specifically mentioned should follow directions for use for mid-South, Southeast, and TX (east of 1-35).
3. Do not graze or feed cotton forage. Do not graze or harvest soybean forage or hay within 90 days of last Zorial Rapid 80 application. Multiple Applications Multiple or sequential applications can be made in certain geographic areas, but the total quantity of Zorial Rapid 80 applied in a year must not exceed the broadcast rate in pounds per acre for a given soil type. Follow Special Directions for each geographic region, soil type, and crop. Read mixing, application, and specific crop sections for additional recommendations· and precautions. Mixing Instructions Zorial Rapid 80 may be tank mixed with other herbicides and liquid fertilizer. Herbicides that may be tank mixed with Zorial Rapid 80 are listed in each crop section. All tank mix products must be approved for use on the respective crop.

-0) -8- Predetermine the compatibility of labeled tank mixes under local conditions by mixing small proportional quantities in advance. Amount of Herbicide to Add to One Pt. of Spray

• Carrier (Assuming Volume is 25 Gals. per Acre) Herbicide Formulation Rate Per Acre Level Teaspoons Dry 1 lb. 1.5 Liquid 1 pt. 0.5 If herb,icide(s) do not ball-up or forll1 flakes, sludge, gels, oily films, layers, or other precipitates, then the tested spray mix is compatible. Incompatibility in any of the above described forms will occur within 5 minutes after mixing. If components are incompatible, the use of a compatibility agent approved for agricultural use on the respective crop is recommended. Rerun the above compatibility test with a suitable compatibility agent C/4 teaspoon is equivalent to 2 pts.l100 gals. of spray carrier). Clean and calibrate the sprayer. Add Zorial Rapid 80 to the spray tank already filled with 1/4 the required volume of the water. This will eliminate or minimize foaming. Maintain agitation while filling and spraying. If a bypass line is used, discharge at the bottom of the tank to minimize foaming. Do not allow Zorial Rapid 80 spray mixture to remain in the spray tank overnight because settling could occur and resuspension would be difficult. Begin adding wettable powders, flowable liquids, emulsifiable concentrates, and surfactants after the spray tank is 3/4 full. Continue agitation during the addition of all the materials and while filling and spraying. Products should be added to the spray tank in the following order:

1. Wettable powders and water-dispersible granules. Wettable powders should be premixed in a small amount of water. Water-dispersible granules should be added during filling. Allow both to disperse before other products are added. The order of addition is not important.
2. Flowable liquids
3. Emulsifiable concentrates
4. Surfactants

. ~) -9- Note: In addition, Zorial Rapid 80 may not always be compatible with other formulations of dinitroaniline (DNA) herbicides. Always predetermine tank mix compatibility by mixing small proportional quantities in a quart jar or other small container. If after vigorous shaking there are large flakes, gel, sludge, or other signs of incompatibility, do not spray the combination. Always follow the order of addition given . in the Mixing Instructions section of this label. Application Equipment Ground Application: Apply the recommended rate of Zorial Rapid 80 in 10 or more gals. of water per acre. Apply accurately with a fixed-boom sprayer. Equip sprayer with fan-jet nozzle tips or equivalent for broadcast application. Use nozzle tips which provide uniform coverage for band applications. Use screen size 50-mesh or larger. Be sure to calculate the correct amount of product per acre for band applications. Use the following formulas to determine the appropriate rate and volume per treated acre needed for band applications: band width in inches row width in inches band width in inches row width in inches x x broadcast rate per treated acre broadcast volume per treated acre band rate = per planted acre band volume = per planted acre The solution should be mixed to the maximum label rate and at no point on the field should the solution be applied at a concentration any higher than this rate. Aerial Application: Apply the recommended rate of Zorial Rapid 80 in 5 or more gals. of water per acre. To minimize drift, use Zorial Rapid 80 with a drift control agent such as Nalco-Trol®. Aerial Drift Management Avoiding spray drift at the application site is the responsibility of the applicator. The interaction of many equipment- and weather-related factors determine the potential for spray drift. The applicator is responsible for conSidering all these factors when making decisions. The following drift management requirements must be followed to avoid off-target drift movement from aerial applications to agricultural field crops. These requirements do not apply to forestry applications, public health uses, or to applications using dry formulations.

1. The distance of the outermost nozzles on the boom must not exceed % the length of the wingspan or rotor.

-10- 2. Nozzles must always point backward parallel with the air stream and never be pointed downward more than 45 degrees. Where states have more stringent regulations, they should be observed. The applicator should be familiar with and take into account the information covered in the Aerial Drift Reduction Advisory Information section below. Aerial Drift Reduction AdviSOry Information Information on Droplet Size The most effective way to reduce drift potential is to apply large droplets. The best drift management strategy is to apply the largest 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 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 many nozzle types, lower pressure produces larger droplets. When higher flow rates are needed, use higher flow rate nozzles instead of increasing pressure. • Number of nozzles - 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 practice. Significant deflection from horizontal will reduce droplet size and increase drift potential. • 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. Solid 'stream nozzles oriented straight back produce the largest droplets and the lowest drift. Boom Length For some use patterns, reducing the effective boom length to less than 3/4 of the wingspaf) or rotor length may further reduce drift without reducing swath width.

-11- Application Height Applications should not be made at a height greater than 10ft. 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 increase with increasing drift potential (higher wind, smaller drops, etc.) Wind Drift potential is lowest between wind speeds of 3-10 mph .. However, many factors, including droplet size and equipment type, determine drift potential at any given speed. Application should be avoided below 3 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 patterns 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 can be indicated by ground fog; however, if fog is not present, 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 that moves upward and rapidly dissipates indicates good vertical air mixing.

-12- Sensitive Areas This pesticide should only be applied when the potential for drift to adjacent sensitive areas (e.g. residential areas, bodies of water, known habitat for threatened or endangered species, nontarget crops) is minimal (e.g., when wind is blowing away from the sensitive areas). Application Methods Preplantlncorporated Application (PPI) and Preplant Applications (PPA) for cotton: Apply Zorial Rapid 80 at the recommended rate prior to planting. Incorporate PPI applications within one week after application and not deeper than 2-3 inches. Preemergence Surface Applications (PRE) for cotton, soybeans, and peanuts: Apply Zorial Rapid 80 at the recommended rate prior to the emergence of the crop and weeds. Do not apply when the crop is at or near emergence (soil cracking). Emerged weeds must be controlled by tillage prior to application or tank mixing with a postemergence herbicide, such as Gramoxone® or Roundup®. Split Application - The Zorial SpliPM for cotton and soybeans: First apply 112 of the Zorial Rapid 80 rate preplant incorporated, then apply the remaining 112 of the Zorial Rapid 80 rate preemergence surface as recommended above. The soil surface should be free of clods and existing weeds prior to Zorial Rapid 80 application. Use tillage or a postemergence herbicide to control emerged weeds. Dry Bulk Fertilizer/Zorial Rapid 80 Blends for Use in Cotton Zorial Rapid 80 may be coated onto dry bulk granular fertilizers for fall or spring early preplant surface, preplant incorporated, or preemergence applications. Coating may be conducted by either an in-plant bulk system or the on-board system. Individuals or agents selling Zorial Rapid 80 in dry bulk fertilizer blends are responsible for following all state and local regulations regarding fertilizer/herbicide blending. Rate recommendations, restrictions, and weeds controlled are the same as for the sprayable product. . Slurry the desired amount of Zorial Rapid 80 in an adequate amount of water (3 pts. water per lb. of Zorial Rapid 80) required to uniformly cover the fertilizer particle. Apply slurry to fertilizer, using any closed rotary-drum mixer or other commonly used dry fertilizer blender. Spray nozzles must be positioned to provide uniform coverage of Zorial Rapid 80 onto fertilizer during mixing. Addition of a drying agent may be necessary if the fertilizer/herbicide blend is too wet for uniform application due to high humidity, high urea concentration, and/or low fertilizer use rate. Slowly add the drying agent to the blend until a flowable mixture is obtained. Drying agents are not recommended for use with on-board systems.

-13- Apply 200-750 Ibs. of fertilizer/herbicide blend per acre. Application must be made uniformly to the soil to prevent possible crop injury and to assure satisfactory weed control. Coated fertilizer spread at 112 rate and overlapped to obtain a full rate will insure a more uniform distribution. A shallow (1 to 2-inch) incorporation is desirable for improved weed control. Deeper incorporation may result in unsatisfactory weed control. Formula to determine herbicide used per ton of fertilizer: Ibs. of product per acre Ibs. of fertilizer per acre Geographic Information x 2000 = Ibs. of herbicide per ton of fertilizer. The following geographic regions are described in this label: Mid-South, Southeast, and TX (East of 1-35), which includes the states !If AL, AR, FL, GA, LA, MS, MO (boot heel only), NC, SC, TN, and TX (east of 1-35). Zorial Rapid 80 can be applied preplant incorporated, preemergence surface, or as a split application (when allowed in specific' use directions) in areas with 35 inches or more annual rainfall. In areas with less than 35 inches rainfall, apply only as preplant incorporated or split application (when allowed in specific use directions), unless irrigation is available for incorporation. Zorial Rapid 80 may be used in conventional or conservation (Le., no-till, reduced till) tillage systems. (See special directions for conservation tillage below.) TX (West of 1-35), Southwest OK, and NM which includes the states of NM, OK (west of 1-35 and south of 1-40), and TX (west of 1-35). Precaution: Zorial Rapid 80 may not be used in conventional or conservation tillage cotton systems in areas with more than 65% sand. Zorial Rapid 80 should only be applied as a preemergence application as part of a program in sequence with Prowl® or in combination with Caparol® 4L. . AZ. (includes all areas within state boundaries) Precaution: Zorial Rapid 80 may be applied only as a prep/ant incorporated application. Shallow incorporation is required. When cotton is irrigated up, do not exceed 0.60 Ibs'/A preplant incorporated when applied prior to listing and irrigate every other furrow. Do not exceed 0.60 Ibs'/A on soils with 65% or more sand.

Do not apply in areas with poor drainage. Replacement and Rotational Crops For 16 months following the last Zorial Rapid 80 application, treated acreage must only be rotated to alfalfa, cotton, soybeans, or peanuts. Visual symptoms of injury (loss of pigment [whitening] in the leaf veins) and stand reduction may occur in rotational crops of soybeans or peanuts in TX (west of 1-35), southwest OK, and NM planted within 16 months following the last Zorial Rapid 80 application. In AZ, treated acreage must only be rotated to cotton. Peanuts can be planted as a replacement crop (e.g., following hail damage) 30 days after the last Zorial Rapid 80 application. Soybeans can be planted as a replacement crop 45 days after the last Zorial Rapid 80 application. In areas of the mid-South,

-16- Southeast, and TX (east of 1-35), a light reworking of the soil is recommended to remove existing plant material and maintain herbicidal activity. Zorial Rapid 80 treated acreage may be planted to a cover crop to control soil erosion. Cover crops should be plowed under and not grazed or harvested for 16 months following the last application of Zorial Rapid 80. Small grain cover crops should be broadcast planted rather than drilled to reduce risk of injury. If replanting to cotton, peanuts, or soybeans is necessary, a light reworking of the topsoil will retain the herbicidal activity of Zorial Rapid 80. In AZ replanting will mean irrigating up, so irrigation must be every other furrow. SPECIFIC COTTON DIRECTIONS Zorial Rapid 80 can be used for weed control in all cotton producing states, except CA.

) -24- SPECIFIC PEANUT DIRECTIONS Zorial Rapid 80 can be used for weed control in peanuts in the states of AL, FL, GA, MS, NC, NM, OK, SC, TX, and VA. Zorial Rapid 80 will control certain grass and broad leaf weeds when applied preemergence at planting (see the Weeds Controlled section). Only one application per crop is allowed in peanuts and this application must be made at planting. Zorial Rapid 80 must be applied and incorporated by tillage, irrigation, or rainfall before weeds germinate. For use only in the states of AL, FL, GA, MS, NC, NM, OK, SC, TX, and VA on runner type.or Virginia-type peanut cultivars, including 'Florunner', 'GK-T, 'GA-Runner', 'Southern Runner', 'NC 1', 'VA 938', 'NC 9', 'NC-V11', 'VA-C 92R', 'AgraTech VC-1', and 'NC 1 ~C'. Do not use Zorial Rapid 80 iri other states or on spanish peanut cultivars. Crop tolerance of cultivars not listed on this label may not be acceptable. Rate Selection Broadcast Rate East of the Mississippi River West of the Mississippi River 1 .5 - 1.8 Ibs. of Zorial Rapid 80 per treated acre (Apply preemergence only) 0.5 lb. of Zorial Rapid 80 per treated acre (Apply preemergence only) Use the higher recommended rate when Zorial Rapid 80 is used alone or on fine­ textured soils, or where populations of susceptible weeds are very heavy. Use of rates higher than 0.5 lb. Zorial Rapid 80 west of the Mississippi River will result in crop injury and is not recommended.' Apply as a preemergence surface application immediately after planting and before weeds or crop emerge. Use Precautions • Do not use on peanuts that were treated preplant incorporated with Vernam®, as crop injury will result. .00 not apply Zorial Rapid 80 when peanuts are near cracking, at cracking, or emerged, as crop injury may result. Make only one application per year.

-25- ) • Crop injury may result from the use of Zorial Rapid 80 following Dual when used on very coarse-textured soils, such as sand. • Delaying applications. of postemergence herbicides, such as Starfire®, may be advisable if severe crop whitening is observed (greater than 50%). 'Do not apply in areas with poor drainage. Temporary whitening of the peanut leaves may occur. If the peanut plant is not stressed by adverse environmental factors or diseases, this· whitening generally dissipates within 4-6 weeks after planting. Early season whitening of peanuts from Zorial Rapid 80 does not result in significant crop stunting, stand reduction, or yield loss, if the plants are not stressed by environmental conditions, improper cultural practices, or diseases. High levels of seedling disease, adverse environmental stress, or improper application may result in increased levels of crop whitening or injury. Sequential Applications/Tank Mixes in Peanuts Read and follow all label directions for other herbicides listed below used in either sequential applications or as tank mix partners with Zorial Rapid 80 for specific rate recommendations, application timing, and precautions. Application of Zorial Rapid 80 to freshly tilled soil will give optim~m weed control with crop safety. However, if weeds are emerged at the time of application, use a suitable burndown agent, such as Starfire (paraquat), to control emerged weeds. The burndown herbicide may be applied prior to or tank mixed with the Zorial Rapid 80 treatment. Zorial Rapid 80 is especially useful for control of Florida beggarweed when in weed control programs that utilize cultivation or both preemergence and postemergence herbicides. Zorial Rapid 80 can be applied as a sequential overlay treatmentfollowing apreplant incorporated application of Balan® OF, Sonalan® HFP, Prowl, or Dual. Do not apply Zorial Rapid 80 to peanuts that have been treated with Vernam because of increased potential for crop injury. Zorial Rapid 80 tank mixes with Lasso and Dual will increase preemergence control of the "difficult to control species," such as Florida beggarweed ,and yellow nutsedge, and will broaden the spectrum of species controlled. Zorial Rapid , 80 may be applied as a preemergence tank mix with Lasso and/or Dual. Under most conditions, a burndown application of Starfire (or tank mixes of Starfire and Basagran and/or 2,4-DB) applied early postemergence will improve residual control of Florida beggarweed obtained with Zorial Rapid 80 by removing Florida beggarweeds that germinated or emerged prior to the activation of Zorial Rapid 80. Sequential applications of Classic, Pursuit®, and Butoxone® (2,4-DB) may be used following Zorial Rapid 80 to control tolerant weeds. .

) -26- SPECIFIC ALFALFA DIRECTIONS Zorial Rapid 80 can be used for weed control in alfalfa in the states of AL, AR, AZ, CA, FL, GA, 10, LA, MS, NC, NM, NV, OK, OR, SC, TN, TX, WA, and the portions of CO, KS, and MO south of 1-70. . Use Precautions Do not apply this product through any type of irrigation system. Zorial Rapid 80 is only recommended for preemergent weed control in established alfalfa; do not apply to seedling alfalfa until it has emerged and been actively growing for 5 months. . Do not apply Zorial Rapid 80 within 28 days of harvest. Soil disturbances, such as rodentburrowing and fire ant mounding, may result in temporary bleaching or reduced growth in alfalfa treated with Zorial Rapid 80. Do not apply to alfalfa planted with small grain or grass companion cover, unless injury to the companion crop is acceptable. Alfalfa seed germinating after Zorial Rapid 80 is activated in the soil will not become established. Application Timing and Rates Zorial Rapid 80 may be applied to healthy stands of established alfalfa at 1.25 Ibs./A; do not apply to seedling alfalfa until it has emerged and been actively growing for 5 months. An additional 1.25 Ibs.lA may be applied later in the first crop year to extend late season weed control. . Application in each of the following crop years may be made at 1.25-2.5 Ibs./A, depending upon weed pressure, soil texture, and cultural practices: • Use the lower rate on coarse soils (sand, loamy sand, sandy loam) and when low populations of easily controlled annual weeds are expected. • Use the higher rate on medium- to fine-textured soils (sandy clay through clay) and­ when heavier weed pressure is expected. The 2.5 lb. maximum annual rate may be applied in a single application or in split applications. Do not apply more than 2.5 Ibs./A per calendar year. Incorporation by rainfall, irrigation, or tillage (for example, by spring tine, disk, or spike tooth harrow) is necessary to activate Zorial Rapid 80 in soil before weed seeds germinate and emerge. A minimum of 112-1 .inch of rainfall or irrigation is necessary to incorporate Zorial Rapid 80.

-27- Application may be made during dormancy, as long as soil is not frozen or in actively growing stands. On nondormant alfalfa, application should always follow mowing and removal of hay to ensure spray reaches the soil surface. In nonirrigated areas which have less than 15 inches annual moisture (rainfall and snow combined) or less than 4 inches spring rainfall, fall or winter applications are recommended. Fall or winter applications are necessary for control of winter annual weeds. Zorial Rapid 80 will not control emerged weeds. Established weeds or weeds that emerge before activation may be controlled with postemergent herbicides that bear labeling for use in the culture of alfalfa. Tank Mixes Zorial Rapid 80 may be tank mixed with any of the following products that bear labeling for use on alfalfa. Read and follow directions for use, precautionary statements, and rates of application of these tank mix partners.
