-29- Personal Protective Egunt: Applicators and other handlers must wear: • Long-sleeved shirt and long pants • Chemical-resistant gloves • Chemical-resistant footwear plus socks • Protective eyewear Discard clothing and other absorbent materials that have been drenched or heavily contaminated with this product's concen­ trate. Do not reuse them. Follow manufacturer's instruc­ tions for cleaning/maintaining PPE. If no such instructions for washables, use detergent and hot water. Keep and wash PPE separately from other laundry. Engineering Controls Statements: When handlers use closed systems or enclosed cabs in a manner that meets the require­ ments listed in the Worker Protection Standard (WPS) for ag­ ricyltural pesticides [40 CFR 170.240(d) (4-6)], the handler PPE requirements may be reduced or modified as specified in the WPS. Usar Safety Recommendations: Users should: • Wash hands before eating, drinking, chewing gum, using tobacco or using the toilet. • Reove clothing immediately if pesticide gets inside. Then wash thoroughly and put on clean clothing. Environmental Hazards For terrestrial uses, do not apply directly to water, or to areas where surface water is present, or to intertidal areas below the mean high water mark. 00 not contaminate water when disposing of equipme~t wash waters. This pesticide con­ tains atrazine, which hdS been shown to be toxic to aquatic invertebrates. Runoff and drift from treated areas may be hazardous to aquatic organisms in neighboring are~~. Ground Water and Surface Water Advisory Bicep OF contains both the active ingredients atrazine and metolachlor. BeST AVAILABLE CO ...

-30- Atrazine can travel (seep or leach; through soil and can enter ground water which may be used as drinking water. Atrazine has been found in ground water. Users are advised not to apply atrazine to sand and loamy sand soils where the water table (ground water) is close to the surface and where these soils are very permeable, i.e., well-drained. Your local agricultural agencies can provide further information on the type of soil in your area and the location of ground water. Metolachlor has been identified in limited sampling of ground water and there is the possibility that it may leach through the soil to ground water, especially where soils are coarse and ground water is near the surface. Following application and during rainfall events that cause runoff, metolachlor may reach surface water bodies including streams, rivers, and reservoirs. Care must be taken when using this product to prevent back siphoning into wells, spills, or improper disposal of excess pesticide, spray mixtures, or rinates. Check valves or antisiphoning devices must be used on all mixing equipment. This product may not be mixed/loaded or used within 50 feet of all wells, includig abandoned wells, drainage wells, and sink holes. Operations that ipvolve mixing, loading, rinsing, or washing of this product into or from pesticide handling or applica­ tion equipment or containers within 50 feet of any well are prohibited unless conducted on an impervious pad constructed to withstand the weight of the heaviest load that may be positioned on or moved across the pad. Such a pad shall be designed and maintained to contain any product spills or equipment leaks, container or equipment rinse or wash-water, and rain-water that may fallon the pad. Surface water shall not be allowed to either flow over or from the pad, which means the pad must be self-contained. The pad shall be sloped to facilitate material removal. An unroofed pad shall be of sufficient capacity to contain at a minimum 110% of the capacity of the largest pesticide container or application equipment on the pad. A pad that is covered by a roof of sufficient size to completely exclude precipit.ation from contact with the pad shall have a minimum containment capacity of 100% of the capacity of the largest pesticide container or application equipment on the pad. Containment capacities as described above shall be maintained at all times. The above-specified minimum containment capacities do not apply to vehicles when delivering pesticide shipments to the mixing/loading site. BEST AVAILABLE CO'" 3.3 1- 3

-.5- General Information Bicep OF is a selective herbicide recommended as an early pre­ plant, preplant surface-applied, preplant incorporated, preemer­ gence, postemergence broadcast or pos~emergence-directed treat­ ment for control of most annual grasses and broadleaf weeds in corn and as an early preplant, preplant surface-applied, pre­ plant incorporated, or preemergence treatment for control of most annual grasses and broadleaf weeds in grain or forage sor­ ghum provided the sorghum seed has been properly treated by the seed company with Concep®. This product may be tank mixed with Banvel®, Bladex® (4L, BOW, 900F), Oual® formulations, AAtrex® 4L (BOW, Nine-O®), Lorox® or eqaivalent, or Princep® 4L (BOW or Caliber 90®) for weed control in conventional tillage corn. This product may also be tank mixed with either Gramoxone® Extra or Roundup® alone or in combination with AAtrex, Bladex, Oual or Princep, in minimum- tillage or no-tillage corn, or tank mixed with either Gramoxone Extra or Roundup, in minimum-tillage or no-tillage sorghum. Following many years of continuous use of atrazine (one of the ingredients in Bicep OF), and products chemically related to atrazine, biotypes of some of the weeds listed on this label which are controlled by the atrazine component have been reported to develop resistance to this and chemically related herbicides. Where this is known or suspected and weeds con­ trolled by this product are expected to be present along with resistant biotypes, we recommend the use of Bicep OF in combina­ tion or ~n ~~quence with registered herbicides which do not con­ tain triazines. Consult with your State Agricultural Extension Service for specific recommendations. Precautions: 1) If sorghum seed is not properly pretreated with Concep. Bicep OF will severely injure the crop. 2) Injury may occur to corn or sorghum follow'_ng the use of Bicep OF under abnormally high soil moisture conditions during early develop­ ment of the crop. Bicep OF alone or in tank mixture with AAtrex, Bladex, Dual, or Princep may be applied early preplant, preplant-surface, pre­ plant incorporated, or preemergence on corn in water or fluid fertilizer. Bicep OF may be applied in tank mix combination with Gramoxone Extra or Roundup with or without the above herbi­ cides preplant surface or preemergence to corn. Apply the early postemergence treatment on corn in water only. Bicep OF alone may also be applied on sorghum early preplant, preplant incorpo­ rated, preplant-surface or preemergence in water or in flqid fertilizer. To avoid spray drift, do not apply under windy conditions. Avoid spray overlap, as crop injury may result. 00 not apply this product through any type of irrigation system. BeST AVAILABLE COI'\

q -6- Dry weather following preemergence application of Bicep DF or a tank mixture may reduce effctiveness. Cultivate if weeds develop in conventi0nal tillage corn or sorghum. Observe all precautions and limitations on the label of each product used in tank mixtures. Thoroughly clean sprayer or other application device before using. Dispose of cleaning solution in a responsible manner. Do not use a sprayer or applicator contamjnated with other mate­ rials, or crop damage or sprayer clogging of the application device may occur. Mixing Instructions Thoroughly recirculate larger containers and bulk tanks before using. Bicep OF is a dry flowable that may be mixed with water or fluid fertilizer and applied as a spray. hpplication in Water or Fluid Fertilizers Bicep OF Alone: Fill the spray tank one-half to three-fourths full with water or fluid fertilizer, add the proper amount of Bicep OF, then add the rest of the water or fluid fertilizer. Provide vigorous agitation during mixing and application to maintain a uniform suspension. Tank Mixtures: Fill the spray tank one-half to three-fourths full with water or fluid fertilizer, add the proper amount of Bicep DF, then add AAtrex, Banvel®, linuron, or Princep; next add Dual; then add Gramoxone Extra or Roundup, depending on the tank mix cOinbination desired; and finally add the rest of the water or fluid fertilizer. When Bladex is used in the tank mixture, add it before Bicep DF unless otherwise specified. (See Bladex section under Bicep DF Combinations - Corn for fur­ ther mixing instructions.) Provide vigorous agitation during mixing and application to maintain a uniform suspension. Compatibility Test: Check the compatibility of Bicep DF and tank mixtures in fluid fertilizer by mixing proportionate quan­ tities in a small container, as described below, before mixing in the spray tank. Nitrogen solutions or complete fluid fertil­ izers may replace all or part of the water in the spray. Since liquid fertilizers can vary, even within the same analysis, always heck compatibility each time before reuse. Be espe­ cially careful when using complete suspension or fluid fertiliz­ ers as serious compatibility problems are more apt to occur. Commercial application equipment may improve compatibility in some insances. The followng test assumes a spray volume of 25 gals. per acre. For other spray volumes, make appropriate changes in the ingredients. Check compatibility using this procedure:

1. Add 1 pint of fertilizer to each of 2 one-quart jars with tight lids. 9EST AVAILABLE CO"

) 0 -7- 2) To one of the jars add 1/4 tsp. or 1.2 milliliters of a compatibility agent approved for this use, such as Compex® or Unite® (1/4 tsp. is equialent to 2 pts. per 100 gals. spray). Shake or stir gently to mix. 3) To both jars add the appropriate amount of herbicide(s) . If more than one herbicide is used, add them separately with dry herbicides first, flowables next, and emulsifi­ able concentrates last. After each addition, shake or stir gently to thoroughly mix. The appropriate amount of herbicides for this test follows: Dry herbicides: For each pound to be applied per acre, add 1.4 teaspoons to each jar. Liquid herbicides: For each pint to be applied per acre add 0.5 teaspoon or 2.5 milliliters to each jar. 4) After adding all ingredients, put lids on and tighten, and invert each jar ten times to mix. Let the mixtures stand 15 minutes and then look for separation, large flakes, precipitates, gels, heavy oily film on the jar, or other signs of incompatibility. Determine if the compatibility agent is needed in the spray mixture by comparing the two jars. If either mixture separates, but can be remixed readily, the mixture can be sprayed as long as good agita­ tion is used. If the mixtures are incompatible, test the following methods of improving compatibility: (A) slurry the dry herbicides(s) in water before addition, or (B) add 1/2 of the compatibilty agent to the fer.tilizer and the other 1/2 to the emulsifiable concentrate or flowable her­ bicide before addition to the mixture. If still incom­ patible, do ~ot ~se the mixture. 5) After compatibility testing is complete, dispose of any pesticide wastes in accordance with the dir€ctions in the Storage and Disp05al section at the end of this label. Application Procedures Ground Application: Use sprayers that provide accurate and uni­ form application. Screens in nozzles should be no finer than 50-mesh. Suction and in-line screens should be no finer than 16-mesh. Use a pump with capacity to (1) maintain 35-40 psi at the nozzles, and (2) provide sufficient agitation in tank to keep mixture in suspension. Unless otherwise specified, use a minimum of 10 gals. of spray mixture per acre. Rinse sprayer thoroughly with clean water immediately after use. For band applications, calculate amount to be ~pplied per acre as follows: band width in inches width in inches broadcast rate amount needed X per acre = per acre of field BEST AVAILABLE CO'"

If Bicep DF is to be used preemergence, apply at planting or immediately after planting. 3) If available, sprinkler irrigate within 2 days after application. Apply 1/2-1 inch of water. Use lower water volume (1/2 inch) on coarse-textured soils and higher vol­ ume (1 inch) on finer textured soils. 4) If irrigation is not possible and rain does not occur within 2 days after planting and application, weed control may be decreased. Under these conditions, a uniform, shallow cultivation is recommended as soon as weeds emerge.

\3 -10- FOR ALL SOIL APPLICATIONS PRIOR TO CROP EMERGENCE On Highly Erodible Soils (as defined by SCS) If conservation tillage is practiced, leaving at least 30% of the soil covered with plant residues at planting, apply a maximum of 8.2 Ibs./A as a broadcast spray. Refer to "B" in tables following. If the soil coverage with plant residue is less than 30% at planting, a maximum of 6.6 Ibs./A may be applied. Refer to "A" in tables following. On Soils Not Highly Erodible Apply a maximum of 8.2 Ibs./A as a broadcast spray. Refer to "B" in tables following. FOR POSTEMERGENCE APPLICATION TO CORN If no atrazine was applied prior to corn emergence, apply a maximum of 8.2 Ibs./A broadcast. If a postemergence treatment is required following an earlier herbicide application, the total atrazine applied may not exceed 2.5 Ibs. active ingredi­ ent (10.1 Ibs. of Bicep OF) per acre per calendar year. Application Timings Early Preplant (Corn): Use on medium- and fine- textured soils with minimum-tillage or no-tillage systems in CO, lA, IL, IN, KS, KY, MN, MO, MT, NO, NE, SO, TN, WI, and WY. Apply 2/3 the recommended rate of Bicep OF as a split treatment 30-45 days before planting and the remainder at planting using the rates in Table 1. Applications made less than 30 days prior to planting may be as either a split or single treatment. Use the lower rate for light expected weed infestations and the higher rate for heavy expected weed infestations. On coarse-textured soils, apply 6.6 Ibs./A not more th?n 2 weeks prior to planting. The above procedure may be followed if A~trex or Dual or Princep is used in tank mixtures with Bicep DF. If weeds are present at the time of treatment, apply in a tank mixture combination with a contact herbicide (for example, Gramoxone Extra or Roundup) . Observe directions for use, precautions, and restrictions on the label of the contact herbicide. On medium- and fine-textured soils with minimum- or no-tillage syster.1s in DE, MO, MI, NY, OH, PA, VA, AND WV, early preplant applications may be applied following the directions for use above. If the amount of rainfall results in unsatisfactory length of weed control following the earlier trectment, a post­ emergence application of an appropriately labeled broadleaf and/or grass weed herbicide may be used, i.e., AAtrex, BEST AVAILABLE CO" 1

If the postemergence treatment includes the herbicide used early preplant, do not exceed the labeled rate for corn on a given soil texture. Observe all direction~ for use, precautions, and limitations on the label of the postemergent herbicide. Bicep DF may be used according to the above directions to con­ trol winter wheat planted as a cover crop in IN, KY, and OH, in addition to providing residual weed control. The wheat must be less than 6 inches tall (preferably still in a dormant or semi­ dormant state coming out of winter) at the time of application. Depending on rainfall, 10-20 days may be required to completely kill the wheat. In the event that adequate rainfall does not occur, control of the winter wheat may be unsatisfactory and the application of a contact herbicide (i.e., Gramoxone Extra or Roundup) may be required before planting the crop. On medium- and fine-textured soils following final seed bed preparation in the Blackland and Gulf Coast areas of TX, an early preplant application of Bicep DF at 4.9 to 5.9 lbs./A may be made 30-45 days before planting. Grass suppression of 2-3 weeks after planting can be expected as a result of this application. Do not incorporate or disturb the soil before planting and avoid moving the soil during the planting opra­ tion. A follow-up application of Dual may be needed in fields with a history of heavy grass pressure. Apply after planting, but before corn and grass weeds emerge. Notes: (1) If a follow-up application of Dual is needed, do not exceed a total of 2.5 lbs. ai of meto1achlor/A including the preplant Bicep DF application on medium or fine-textured soils. On fine-textured soils wit .. more than 3% organic matter, do not exceed 3 Ibs. ai of metolachlor.
