-5- FAILURE TO FOLLOW THE DIRECTIONS FOR USE AND PRECAUTIONS ON THIS LABEL MAY RESULT IN POOR WEEP CONTROL. CROP INJURY. OR ILLEGAL RESIDUES. Bicep 4.5L is a selective herbicide recommended as a preplant surface-applied, preplant incorporated, preemergence, post­ emergence broadcast or postemergence-directed treatment for con­ trol of most annual grasses and broadleaf weeds in corn (field corn, silage corn, sweet corn, or popcorn) and as a preplant surface-applied, preplant incorporated, or preemergence treat­ ment for control of most annual grasses and broadleaf weeds in grain or forage sorghum provided the sorghum seed has been prop­ erly treated by the seed company with Concepe. This product may be tank mixed with Bladexe (4L, BOW, 90WDG), Duale formulations, AAtrex® 4L (BOW, Nine-O®), or Princepe 4L (SOW or Calibere 90) for weed control in conventional tillage corn. This product may also be tank mixed with either Gramoxone® Extra or Roundupe alone or in combination with AAtrex, Bladex, Dual 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 4.5L), 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 4.5L in combination or in sequence with registered herbicides which do not contain triazines. Consult with your State Agricultural Extension Service for specific recommendations. Precautions; II If sorghum seed is not properly pretreated with Concep. Bicep 4.SL will severely injure the crop. 21 Injury may occur to corn or sorghum following the use of Bicep 4.5L under abnormally high soil moisture conditions during early develop­ ment of the crop. Bicep 4.SL alone or in tank mixture with AAtrex, Bladex, Dual, or Princep may be applied preplant incorporated, preplant sur­ face, or preemergence on corn in water or fluid fertilizer. Bi­ cep 4.SL may be applied in tank mix combination with Gramoxone Extra or Roundup with or without the above herbicides preplant surface or preemergence to corn. Apply the early postemergence treatment on corn in water only. Bicep 4.5L alone may also be applied on sorghum preplant incorporated, preplant surface, or preemergence in water or in fluid fertilizer. Bicep 4.SL may be applied in water by aircraft. Applications in fluid fertilizer should be only by ground equipment . .. '

-6- To avoid spray drift, do not apply under windy conditions. Avoid spray overlap, as crop injury may result. Do not apply this product through any type of irrigation system. Dry weather following preemergence application of Bicep 4.SL or a tank mixture may reduce effectiveness. Cultivate if weeds develop in conventional tillage corn or sorghum. Observe all precautions and limitations on the label of each product used in tank mixtures. Thoroughly clean sprayer prior to use. contaminated with any other materials, clogging may result. Mixing Instructions Do not use a sprayer or crop damage or sprayer Shake well before using. Bicep 4.SL is a liquid that may be mixed with water or fluid fertilizer and applied as a spray. Bicep 4.SL may also be sprayed onto dry bulk granular fertilizer and applied with the granular fertilizer. Dry Bulk Granular Fertilizers Many dry bulk granular fertilizers may be impregnated or coated with Bicep 4.SL and used to control weeds in corn or Concep-treated sorghum. When applying Bicep 4.SL with dry bulk granular fertilizers, follow all directions for use and precautions on the Bicep 4.SL label regarding target crops, rates per acre, soil texture, application methods, nd rotational crops. All individual state regulations relating to dry bulk granular fertilizer blending, registration, labeling, and application are the responsibility of the individual and/or company selling the herbicide/fertilizer mixture. Prepare the herbicide/fertilizer mixture by using any closed drum, belt, ribbon, or other commonly used dry bulk fertilizer blender. Nozzles used to spray Bicep 4.SL onto the fertilizer must be placed to provide uniform spray coverage. If the herbiciaq/fertilizer mixture is too wet, use a highly absorptive pow a r, such as Microcel E (Johns-Manville Produts Corporation), diatomaceous earth or finely powdered clay, to obtain a dry free-flowing mixture. Add the absorptive powder separately and uniformly to the herbicide/fertilizer mixture and blend to form a suitable free-flowing mixture. Generally, less than 2% by weight of absorptive powder will be needed . .. ' "

-7- Calculate the amount of Bicep 4.SL to be used by the following: 2.000 Ibs. of fertilizer per acre x qts. of Bicep 4.SL per acre = qts. of Bicep 4.SL per ton of fertilizer Precautions: To avoid potential for explosion. (1) po not impregnate Bicep 4.SL on ammonium nitrate. potassium nitrate. or sodium nitrate either alone or in blends with other fertilizers. (2) po not combine Bicep 4.SL with a single supeosphate (0-20-0) or treble supehosphate /0-46-0). (3) po not use Bi­ cep 4.SL on straight limestone. since absorption will not be achieved. Fertilizer blends containing limestone can be impreg­ nated. Application Apply 200-700 pounds of the herbicide/fertilizer mixture per acre. For best results, apply the mixture uniformly to .. the soil with properly calibrated equipment immediately after blending. Uniform application of the herbicide/fertilizer mixture is essential in order to prevent possible crop injury or injury to subsequent rotational crops. Non-uniform application may also result in unsatisfactory weed control. In areas where conven­ tional tillage is practiced, a shallow incorporation of the mix­ ture into the soil is recommended to obtain satisfactory weed control. On fine or medium-textured soils in areas where soil incorporation is not planned, i.e., reduced tillage situations or in some conventional till situations, make applications approximately 30 days before planting to allow moisture to move the herbicide/fertilizer mixture into the soil. On coarse­ textured soils, make applications approximately 14 days prior to planting. Precautions: (1) To help avoid rotational crop injury. make applications as early as possible. since Bicep 4.SL impregnated onto dry bulk granular fertilizers can be expected to last longer in the soil than when Bicep 4.SL is applied as a spray in water or fluid fertilizer. (2) po not use on crops where bed­ ding occurs. or crop injury may occur. application in Water or Fluid Fertilizers Bicep 4.SL Alone: Fill the spray tank onehalf·tn-Lhreefourths full with water or fluid fertilizer, add the proper amount of Bicep 4.SL, then add the rest of the water or fluid fertilizer. Provide sufficient agitation during mixing and application to maintain a uniform suspension. ~ank Mixtures: Fill the spray tank one-half to three-fourths full with water or fluid fertilizer, add the proper amount of Bicep 4.SL, then add AAtrex, Banvel, linuron, or Princep; next

-8- add Dual; then Gramoxone Extra or Roundup, depending on the tank mix combination desired; and finally add the rest of the water or fluid fertilizer. When Bladex is used in the tank mixture, add it before Bicep 4.5L unless otherwise specified. (See Bladex section under Bicep 4.5L Combinations-Corn for further mixing instructions.) Provide sufficient agitation during mixing and application to maintain a uniform suspension. Compatibility Test: Check the compatibility of Bicep 4. 5L 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 check compatibility each time before reuse. Be espe­ cially careful when using complete suspension or fluid fertilizers as serious compatibility problems are more apt to occur. Commercial application equipment may improve compatibil­ ity in some instances. The following test assumes a spray vol­ ume of 25 gals. per acre. For other spray volumes, make appro­ priate 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.
2. To Qfie 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 equivalent 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 emulsifiable concentrates last. After each addition, shake or stir gen­ tly to thoroughly mix. The appropriate amount of herbi­ cides for this test follows: Dry herbicides: Liquid herbicides: For each pound to be applied per acre add 1.4 teaspoons to each jar. 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, pre­ cipitates, 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 agitation is

-9- II i 3S used. If the mixtures are incompatible, test the following methods of improving compatibility: (A) slurry the dry hert><.cide (s) in water before addition, or (B) add 1/2 of the compatibility agent to the fertilizer and the other 1/2 to the emulsifiable concentrate or flowable herbicide before addition to the mixture. If still incompatible, do not use the mixture. Application Procedu~ Ground Application: Use sprayers that provide accurate and uni­ form application. Screens in nozzles and in suction and in-line strainers should be no finer than 50-mesh. Use a pump with capacity to (1) maintain 35-40 psi at the nozzles, and (~) pro­ vide 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 applied per acre as follows: band width in inches row width in inches broadcast rate amount needed X per acre = per acre of field Aerial Application (for Bicep 4.SL alone): Use aerial applica­ tion only where broadcast ~pplications are specified. Apply a minimum of 1 gal. of water for each 1 gal. of this product applied per acre, but for rates below 1 gal./acre, use in suffi­ cient water to equal 2 gals./acre of total spray. Avoid appli­ cations under conditions where uniform coverage cannot be obtained or where excessive spray drift may occur. In order to assure that spray will be controllable within the target area when used according to label directions, make applications at a maximum height of 10 ft., using low drift nozzles at a maximum pressure of 40 psi, and restrict application to periods when wind speed does not exceed 10 mph. To assure that spray will not adversely affect adjacent sensitive nontarget plants, apply Bicep 4.SL by aircraft at a minimum upwind distance of 400 ft. from sensitive plants. Avoid application to humans or animals. Flagmen and loaders should avoid inhalation of spray mist and prolonged contact with skin. Within rate ranges in all tables on this label, use the lower rate on soil I'elatively coarse-textured or low in organic mat­ ter; use the higher rate on soil relatively fine-textured or high in organic matter.

1. Thoroughly till moist soil to de~troy germinating and emerged weeds. If Bicep 4.SL is to be applied preplant incorporated, this tillage may be used to incorporate Bicep 4.SL if uniform 2 inch incorporation is achieved as recom­ mended under Application Procedures.
2. Plant crop into moist soil iromediate1y after till~. If Bicep 4.SL is to be used preemergence, apply at planting or immediately after planting.
3. If available, sprinkler irrigate within 2 days after appli­ cation. Apply 1/2-1 inch of water. Use lower water volume (1/2 inch) on coarse-textured soils. Also, refer to the section on Center Pivot Irrigation Application for this method of applying Bicep 4.SL. 0"

-11- 13~ 35 4) If irrigation is not possible and rain does not occur with­ in 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. Bicep 4.5L Rate Limitations - Corn and Sorghum *Where there are state/local requirements regarding atrazine use (including lower ~aximum rates and/or greater setbacks) which are different from the label, the more restrictive/protective requirements must be followed. Certain states have established rate limitations within specific geographical areas. Consult your state lead pesticide control agency for additional informa­ tion. It is a violation of this label to deviate from state use regulations. Note: For purposes of calculating total atrazine active ingre­ dient applied, Bicep 4.5L contains 2.0 lbs. ai per gal. (0.5 lb. ai per qt.). FOR ALL SOIL APPLICATIONS PRIOR TO CROP EMERGENCE On Highly Erodible Soils (as defined by SCSI • If conservation tillage is practiced, leaving at least 30% of the soil covered with plant residues at planting, apply 4 qtS./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 3.2 qtS./A may be applied. Refer to "A" in tables following. • On Soils Not Highly Erodible Apply a maximum of 4 qts./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 4 qts./A broadcast. If a postgmergence treatment is required following an earlier herbicide application, the total atrazine applied may not exceed 2.5 lbs. active ingredient (5 qts. of Bicep 4.5L) per acre per calendar year. Application Timings Preplant Surface Applied (Corn): Use on medium- and fine­ textured soils with minimum-tillage or no-tillage systems in CO, lA, IN, IL, KS, KY, MN, MO, MT, NO, NE, SO, TN, WI, and WY . .. ,

-12- Apply 2/3 the recommended rate of Bicep 4.SL (3.2-4 qts./A o~ medium soils and 4 qts. on fine soils) as a split treatment 30-45 days before planting and the remainddr at planting. 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 coars.-textured soils, apply 3.2 qts./A not more than 2 weeks prior to planting. The above pro­ cedure also may be followed if AAtrex or Dual BE or Princep is used in tank mixtures with Bicep 4.SL. 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 systems in DE, MD, MI, NY, OH, PA, VA, and WV, preplant surface 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 treatment, a post­ emergence application of an appropriately labeled broadleaf and/or grass weed herbicide may be used, i.e., AAtrex, Basagran®, 2,4-0, Banvel®, bromoxynil (Brominal® or Buctril®) . If the postemergence treatment includes the herbicide used pre­ plant surface-applied, do not exceed the labeled rate for corn on a given soil texture. Observe all directions for use, pre­ cautions and limitations on the label of the post emergent herbi­ cide. Note: To the extent possible, do not move treated soil out of the row or move untreated soil to the surface during planting, or weed control will be diminished. Preplant Surface-IJplied (Sorghum-Seed Treated with Concep) : For minimum-tillage and no-tillage systems only, Bicep 4.SL may be applied up to 45 days before planting grain sorghum in IL, lA, eastern KS, MO, NE, and SO. Use only split applications for treatments made 30 to 45 days before planting with 2/3 the rec­ ommended rate applied initially and the remaining 1/3 at plant­ ing. On medium soils with greater than 1.5% organic matter, and on fine soils with less than 1.5% organic matter, apply 3.2-3.6 qts./A of Bicep 4.SL; on fine soils with greater than 1.5% organic matter, apply 3.6-4 qts./A of Bicep 4.SL. Applications made less than 30 days prior to planting may be as either a split or a single application. If weeds are present at the time of treatment, apply in a tank mixture combination with a contact herbicide (for example, Gra­ moxone Extra or Roundup). Observe directions for use, precau­ tions, and restrictions on the label of the contact herbicide. Under dry conditions, irrigation after application is recom­ mended to move Bicep 4.SL into the soil. Use of low rates on fine soils may result in reduced control of certain broadleaf weeds. ..'

-13- Note: To the extent possible, do not move treated soil out of the row or move untreated soil to the surface during planting, or weed control will be diminished. Do not use on coarse soils. Do not use on medium soils with less than 1.5% organic matter. Preplant Incorporated or Preemergence (Corn or Sorghum-Seed Treated with Concep): Apply Bicep 4.5J. preplant incorporated or preemergence using the appropriate rates from Table 1 for corn, or from Table 2 for sorghum. Preplant Incorporated: Apply to the soil and incorporate into the top 2 inches of the soil within 14 days prior to planting uSing a finishing disk harrow, rolling cultivator, or similar implement capable of providing uniform 2-inch incorporation. Use preplant incorporated if furrow irrigation is used or when a period of dry weather after application is expected. If crop is to be planted on beds, apply and incorporate after bed forma­ tion. Preemergence: Apply to the soil surface at planting (behind the planter), or after planting but before weeds or crop emerge. I~ ~35

-16- Rotational Crops: (1) If treated crop is lost due to poor ger­ mination, hail, flood, insects, etc., corn may be replanted immediately or sorghum may e replanted immediately provided the seed has been properly treated with Concep. Do not make a sec­ ond broadcast application. If the original application was banded and the second crop is planted in the untreated row middles, a second banded treatment may be applied. (2) Corn, sorghum, soybeans, cotton, or peanuts may be planed the spring following treatment. Do not graze or feed forage or fodder from cotton to livestock or illegal residues may result. Injury may occur to soybeans planted the year following application on soils having a calcareous surface layer, including, but not lim­ ited to those found in north-central and northwest IA; south-central, western and southwest MN; northeast NE; NO and eastern SO. (3) If applied after June 10, do not rotate with crops other than corn or sorghum the next year, or crop injury may occur. (4) In the High Plains and Intermountain areas of the West where rainfall is sparse and erratic or where irriga­ tion is required, use only when corn or sorghum is to be planted the following year, or a crop of untreated corn or sorghum is to pecede other rotational crops. (5) Small grains may be planted 15 months following treatment. (6) All other crops may be planted 18 months after application.

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. Do not contaminate water when disposing of equipment wash waters. his pesticide contains atrazine, which has been shown to be tcxic to aquatic inverte­ brates. Runoff and drift from treated areas may be hazardous to aquatic organisms in neighboring areas. Ground Water and Surface Water Advisory Bicep 4.5L contains both the active Llgredients atrazine and metolachlor. Atrazine can travel (seep or leah) 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 agricul­ tural agencies can provide further information on the type of soil in your area and the location of ground water . ...

-28- 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 rinsates. Chec~ valves or antisiphoning devices must be used on all mix­ ing equipment.
