1. Best Management Practices for the Protection of Ground and Surface Water This pr01uct may not be mixed or loaded within 50 feet of perennial or intermittent streams and rivers, natural or impounded .lakes, .and reservoirs. This product may not be ~ mixed, loaded or used within 50 feet of all wells, inc lud­ ~ ·ing abandoned wells, drainage wells, and sinkholes. This A product may not be applied aerially or by ground within I ·66 feet of the points where field surface water run-off enters pe:rennia::' or intermittent streams and rivers or within 200 ft. of natural or impounded lakes and reser­ voirs. This product may only be applied to highly erodible land if the 66 foot buffer or setback from run0ff point5 is planted to crop or seeded with grass. Operations that involve mixing, loading, rinsing, or wash­ ing of this product into or from pesticide handling or application equipment or containers within 50 fe~t of any well are prohibited unless conducted on an imperevious pad constructed to withstand the weight of the heaviest load that may be positioned en or moved across the pad. Such a pad shall be designed ~nd maintained to contain any product spills or equipment leaks, container or equipment rinse or wash-water, and rainwater 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 precipitation 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 deliv- . ' ..

Where there are state/local requirements regarding cyanazine use (including lower maximum rates and/or higher setbacks) which are different from the label, the more restrictive/protective requirements apply. Cyanazine Rate Limits Cycle Herbicide contains 2 Ibs. of cyanazine active ingredient per gallon. a. Do not apply more than 6.5 Ibs. total cyanazine a.i. (all sources) per acre per year to ,any land. b. On highly eLodible land, as defined by the Soil Conservation Service, if plant residue cover is less than 30%, do not apply more than 3.0 Ibs. total cyana"ine·a.i. (all sources) per acre per year. '. A. : .General Information Cycle is a selective herbicide which will control most annual grasses and certain broadleaf weeds in corn and grain sorghum. Cycle can be mixed with water or fertilizer and applied as an early preplant, preplant surface-applied, preplant incorporated, or preemergence treatment. Where directions specify a Cycle tank mixture with an AAtrex® or Princep@ formulation, other brands of atrazine or simazine may be used. Cycle may also be tank mixed with Bicep®. Follow the practices, recommendations, and limita­ tions on the respective product labels. Follow the rates, recommendations, and limitations on the AAtrex or respec­ tive atrazine product label, if other brands of atrazine are used. For reduced tillage or no-till practices, Gramoxone® Extra or Roundup® may be mixed with Cycle and Cycle Lank mixtures. For some specific no-till practices, 2,4-0 and/or Banvel® may be added. Where tank mixtures are planned with 2,4-D and/or Banvel, check thoroughly for compatibility before mixing in the spray tank. : The aine form of 2,4-0 tends to be more compatible in the tank mix. Observe all precautions nd limitations on the labels of each product used in tank mixtures. Tank mixtures are permitted only in thoe states where the tank mix partner is registered. . I.

) ) 1. -6- Note: Certain states may have established rate limitations for atrazine within specific geographical areas. Consult your state lead pesticide control agency for additional information. It is a violation of this label to deviate from state use regulations. If Cycle is incorporated, any supplemental tillage before planting must not exceed the depth of incorporation. Dry weather following a preemergence application of Cycle alone or a tank mixture may reduce effectiveness. Culti­ vate if weeds appear. When reference is made to weeds partially controlled, par­ tial control can either mean erratic control from good to poor, or consistent control at a level below that generally considered acceptable for commercial weed control. Following many years of continuous use of cyanazine (one of the ingredients in Cycle), and products chemically related to cyanazine, tiotypes of some of the weeds listed'on this iabel which are controlled by the cyanazine component have been reported to develop resistance to this and chemically related herbicides. Where this is known or suspected and " weeds controlled by this product are expected to be present along with resistant biotypes, we recommend the use of Cycle in combination or in sequence with registered herbi­ cides which do not contain triazines. Consult with your state Agricultural Extension Service for specific recommen­ dations. Precaution: 1) Injury may occur following the use of Cycle under abnormally high soil moisture conditions during early development of the crop. 2) Do not apply Cycle postemer­ gence over-the-top of corn or grain sorghum. since injury may occur. Soil Textures and Herbicide Rates Where rates are based n coarse-, medium-, or fine-textured soils, it is understood that soi textural classes are generally categoLized as follows: Sand Loamy sand Sandy loam Medium Loam Silt silt loam Fine Silty clay loam Sandy clay loam Silty clay Sandy clay Clay loam Clay Within rate ranges in the rate tables and elsewhere on this

) 2. ) -7- label, use the lower rate on soils relatively coarse-textured or low in organic matter; use the higher rate on soils relatively fine-textured or high in organic matter. Note: Cycle, alone or in tank mixture, may be applied preemergence following preplant surface or preplant incor­ porated application of other herbicides. When applying Cycle following a preplant treatment that contains meto­ lachlor or cyanazine, do not exceed the maximum labeled rate for these herbicides on corn or grain sorghum. Thoroughly clean sprayer or other application device before using. Dispose of cleaning solution in a responsible man­ ner. Do not use a sprayer or applicator contaminated with other materials, or crop damage or clogging of the applica­ tion device may occur. Mixing Instructions Cycle AIQlle: Mix Cycle with water or fluid fertilizer. Fill the spray tank one-half to three-fourths full with water or fluid fertilizer, add the proper amount of Cycle, '. and then add the rest of the water or fluid fertilizer. 1 Provide sufficient agitation during mixing and application to maintain a uniform suspension. Tank Mixtures: Fill the spray tank one-fourth full with water, and start agitation. Note: When one or more tank mix partners are used with Cycle, allow each to fully dis­ perse before adding the next product. Then, add Cycle. If Gramoxone Extra or Roundup is being used with Cycle or Cycle tank mixtures, add it after Cycle and then add the remainder of the water. For tank mixtures with AAtrex, Bicep or Princep, fluid fer­ tilizers may replace all or part of the water as the car­ rier. For tank mixtures with other herbicides, see addi­ tional mixing instructions on their respective labels. For each mixture check compatibility with fluid fertilizer, as described below, before mixinr in spray tank. For all tank mixtures, agitate during mixin and application to maintain a uniform suspension. Note: Do not mix Gramoxone Extra with suspension-type fluid fertilizers containing clay as the spray carrier. Compatibility Test: Since liquid fertilizers can vary, even within the same analysis, always check compatibility with herbicide(s) each time before use. Be especially careful when using complete suspension or fluid fertilizers since serious compatibility problems are more likely to occur. Commercial compatibility agents may improve

) .) -8- compatibility in some instances. The following 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.
2. To 2ne 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 . , 4 . To QQth 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 1.5 level teaspoons to each jar. For each pint to be applied per acre, add 0.5 teaspoon or 2.5 mil­ liliters to each jar. 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 herbicide(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 her­ bicide before addition to the mixture. If incompatibility is still observed, do not use the mixture.
3. After compatibility testing is complete, dispose of any pesticide wastes in accordance with the directions in the Storage and Disposal section at the end of this label.
4. Application Procedures Application Timing Cycle alone or in tank mixtures with other labeled herbi- .,~

) '. ) -9- ides may be applied for weed control in corn and grain sorghum. Refer to the appropriate crop section of the label of the tank mix partner to determine if application timings listed below are recommended. (1) (2) (3 ) Early Prep1ant and Preplant Surface Applied: For reduced-tillage or no-tillage systems only, Cycle alone or Cycle plus AAtrex, Bicep or Princep, may be applied before planting as specified in the corn or grain sorghum section of the label. Use only split applications for early preplant treatments made 30-45 days before planting with 2/3 the recommended broad­ cast rate for the crop and soil textur applied initially and the remaining 1/3 at planting. Treat­ ments fewer than 30 days before planting may be made either as a split or a single application. If actively growing annual weeds less than 2 inches in height are present at time of treatment, apply Cycle alone or with AAtrex or Bicep as indicated in the Cycle Combinations section of the label. If weeds are present and exceed 2 inches in height at time of treatment, apply in a tank mixture with a contact herbicide (for example, Gramoxone Extra or Roundup) either alone or with AAtrex, Bicep or Princep as indicated in the Cycle Combinations section of this label. If perennial broadleaf weeds are present at the time of treatment, the addition of 2,4-D or Banve1 may improve performance. For best results, the spray gallonage and application procedure must be such that complete coverage of the foliage is obtained. Observe directions for use, precautions, and restric­ tions on the labels of the herbicides used. 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 Incorporated: Apply Cycle or Cycle plus AAtrex, Bicep or Princep to the soil and incorporate into the top 2 inches of soil within 14 days before planting. Use a finishing disk, harrow, rolling cultivator, or similar implement capable of providing uniform 2 inch incorporation. Use a preplant incorpo­ rated application if furrow irrigation is used or if a period of dry weather after application is expected. If the crop will be planted on beds, apply and incor­ porate Cycle or Cycle tank mixtures after bed forma­ tion unless specified otherwise. Preemergence: Apply Cycle or Cycle plus AAtrex, Bicep and princep, during planting (behind the planter) or after planting, but before weeds or crops emerge. .';'

) ) '. -10- Ground Application: Apply Cycle alone or in tank mixtures by ground equipment in a minimum of 10 gals. of spray mix­ ture per acre unless otherwise specified. Use sprayers that provide accurate and uniform application. For Cycle tank mixtures with wettable powder or dry flow­ able formulations, screens and strainers should be no finer than 50-mesh. Rinse sprayer thoroughly with clean water immediately after use. Calculate the amount of herbicide needed for band treatment by the formula: band width in inch~ broadcast rate amount needed = per acre of field row width in inches X per acre Avoid application to humans or animals. Loaders should avoid inhalation of spray mist and prolonged contact with skin and should wash thoroughly before eating and at the end of each day's operation. Notes: (1) Do not irrigation system. apply this product through any type of (2) Do not apply by aerial equipment. 4. Dry Bulk Granular Fertilizers Many dry bulk granular fertilizers may be impregnated or coated with Cycle al0n~ or with selected Cycle tank mix­ tures which are (1) registered for preplant incorporated or preplant-surface application; (2) which are used to control weeds in corn; and (3) are not prohibited from use on dry bulk granular fertilizers. When applying Cycle or Cycle mixtures with dry bulk granu­ lar fertilizers, follow all directions for use and precau­ tions on the respective product labels including rates per acre, soil texture, application methods (including timing of application), and 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 mixtures by using any closed drum, belt, ribbon, or other commonly used dry bulk fertilizer blender. Nozzles used to spray Cycle onto the fertilizer must be placed to provide uniform spray cover­ age. Care should be taken to aim the spray onto the fer­ tilizer only, and to avoid spraying the walls of the blender. 11r+=</--!"

) ) -11- If the herbicide/fertilizer mix is too wet, add a highly absorptive material such as Agsorb®, or similar granular clay materials, to obtain a dry free-flowing mixture. Absorptive materials should be added only after the herbi­ cide has been thoroughly blended into the fertilizer mix­ ture. Actively blend the herbicide/fertilizer mixture for five minutes before adding absorptive materials. Best application results will be obtained by using a granule of 6/30 particle size or of a size similar to that of the fertilizer material being used. Generally, less than 2% by weight of absorptive material will be needed. Avoid using more than 5% absorptive material by weight. When the impregnation process is being conducted with on-board impregnation devices on pneumatic applicators, use of absorptive materials (drying agents) is not recommended. Calculate amounts of Cycle, AAtrex, Bicep or Princep by the following formula: '2.00~ Ibs. of fertilizer per acre . 2.000 lbs. of fertilizer per acre x pts./acre of liquid or· flowable product = pts. of liquid or flowable product per ton of f8rtilizer lbs. of dry product lbs./acre of dry X product = per ton of fertilizer ~recautions: To avoid potential for explosion. (1) Do not imPLegnate Cycle or Cycle mixtures on ammonium nitrate. potassium nitrate or sodium nitrate either alone or in blends with other fertilizers. (2) Do not combine Cycle or Cycle mixtures plus any other herbicide with single super­ ~osphate (0-20-0) or treble superphosphate (0-46-0) because inactivation of the herbicide can occur. (3) Do not use Cycle or Cycle mixtures on straight limestone. since absorption will not be achieved. Fertilizer blends containing limestone can be impregnated. Application Apply 200-700 pounds of the herbicide/fertilizer mixture per acre. For best results, use properly-calibrated equip­ ment and apply the mixture immediately after blending. Uniform application of the herbicide/fertilizer mixture is essential to prevent possible crop injury. Non-uniform application may also result in unsatisfactory weed control. In areas where conventional tillage is practiced, a shallow incorp0ration of the mixture into the soil may improve weed control. On fine- or medium-textured soils in areas where soil incorporation is not planned apply the mixture 14 days before planting to allow moisture to move the --.----------------------

) ) -14- Corn - Cycle Alone Apply Cycle early preplant (30-45 days before planting), preplant surface, preplant incorporated, or preemergence using the appropriate rate from Table 1. Do not use on sand or loamy san·j soils with less than 1% organ1c matter. Early Preplant and Preplant Surface Applied: Refer to instructions for use of Cycle alone under Application Procedures. Use on medium- and fine- textuLed soils with minimum-tillage or no-tillage systems in CO, IL, IN, lA, KS, KY, MN, MO, MT, NE, ND, SO, TN, WI, and WY. Broadcast the recommended rate of Cycle for soil texture and percent organic matter indicated in Table 1. In no-till corn where heavy crop residue exists, the rates in Table 1 should be increased by 15%. Under dry conditions, irrigation after application is recommended to move Cycle into the soil. 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 i .the earlier Cycle treatment, a postemergence application of an appropriately labeled broadleaf and/or grass weed herbi­ cide may be used, i.e., AAtrex, Beacon®, Bicep®, 2,4-0, Banvel, Basagran®, bromoxynil (Brominal® or Buctril®), Laddok® or Marksman®. Notes: (1) If the postemergence treatment includes meto­ lachlor, do not exceed the maximum labeled rate for meto­ lahlor on corn based on soil texture. (2) Observe all directions for use, precautions and limitations on the label of the postemergent herbicide. Preplant Incorporaqd or Preemergence: Follow instructions for use of Cycle a le under Application Procedures. Use rates of Cycle for ,oil textures and organic matter levels indicated in Table 1. Notes: (1) Do not apply more than the labeled application rate for a given soil texture per year either as a single or split treatment or illegal residues may result. (2) In. the event of escape of annual broadleaf weeds following preplant surface, preplant incorporated, or preemergence treatm',nt with Cycle, follow with a postemergence applica­ tion of an appropriately labeled broadleaf and/or grass weed herbicide, i.e., AAtrex, Bdsagran, Beacon, Bicep, Brominal, Buctril, Banvel, Laddok, Marksman or 2,4-0. (3) If the postemergence treatment includes metolachlor, do not exceed the maximum labeled rate for metolachlor on corn based on soil texture. . '.

) ) -16- Corn - Cycle Combinations IMPORTANT FOR TANK MIXTURES WITH BICEP OR AATREX (OR OTHER BRANDS OF ATRAZINE) - If applying Cycle in tank mixture with atrex or Bicep. all the restrictions and rate limita­ tions appearing on the AAtrex or Bicep label must be fol­ lowed if more restrictive/protective than those on this label. In additioll. if lAtrex or B.cep is/must be ap.,lied at rates lower than ~hose recommended on this label. broad­ leaf weed control may be affected. Refer to the AAtrex or Bicep label for weeds controlled at the reduced rates.

1. Tank Mixture with AAtrex or Princep In addition to the weeds controlled by Cycle alone, Cycle plus AAtrex or Princep, ~pplied preplant surface, preplant incorporated or preemergence, also controls such additional weeds as follows: cocklebur, common purslane, hairy night­ shade, and velvetleaf. Early preplant and Preplant Surface Applied: Follow instructions for use of Cycle alone under Application Procedures and under application instructions for Cycle Alone on corn. Apply Cycle + AAtrex or Princep in CO, IL, IN, lA, KS, KY, MN, MO, MT, NE, NO, SO, TN, WI, and WY at rates indicated in Table 2. Apply the tank mixtures as a split or single treatment in the 3tates above using the procedure indicated in the Corn - Cycle Alone - Early Pre­ plant and Preplant Surface ~plied section of the label. Preplant Incorpor?ted or Preemergence: Follow instructions for use of Cycle alone under Application Procedures. Apply the rates of Cycle + AAtrex or Princep indicated in Table 2 . Note: Do not apply more than the labeled rate for a given soil texture per year either as a split or single treat­ ment, or illegal residues may result.
2. Tank Mixture with Bicep If a lower rate of atrazine is desired than that applied with Bicep alone, a tank mixture of Cycle plus Bicep may be used for control of annual weeds. Applications may be made early preplant, preplant surface, preplant incorporated or preemergence. For control of actively growing, emerged annual weeds less than 2 inches in height, a contact herbicide will generally not be required for u~e with the Cycle plus Bicep tank mixture.

For weeds exceeding 2 inches in height, addition of a cont2ct herbi­ cide (e. g., Gramoxone Extra or Roundup®) to ·the 'nixture is recommended in accordance with its label. For applications made less than 30 days before planting, apply 1/2-3/4 the recommended rate of Cycle Alone for the given soil texture and organic matter content in Table 1 in tank mixture with 1/2-3/4 the r2te of Bicep alone as speci­ fied in the Bicep label. For applications made 30-45 daya before planting, the rate of Cycle and Bicep as indicated above may be applied as a split treatment with 2/3 of the Cycle and Bicep rates applied initially followed by the remaining 1/3 at plant­ ing. Notes: (1) Tank mixtures of Cycle and Bicep as described above may provide less effective residual control of large seeded broadleaf weeds (e.g., velvetleaf and cocklebur) than Bicep applied alone at the full rate. (2) If" peren­ nial broadleaf w~eds are present at the time of treatment, .the addition of 2,4-D and/or Banvel to the tank mixture in accordance with its label may improve performance.

Apply the rate of Cycle indicated in Table 3. In no-till sorghum where heavy crop resdue exists, the rates in Table 3' should be increased by 15%. Under dry conditions, irrigation after application is recommended to move Cycle into the soil. Preplant Incorporated or Preemergence: Refer to instruc­ tions for use of Cycle under Application Procedures. Apply the rates of Cycle indicated in Table 3. Do not incorpo­ rate Cycle more than three inches deep nor use a spike­ toothed harrow, deep tillage disk or rolling basket device to incorporate Cycle. Precautions; (1) If sorghum seed is not properly treated with Concep. Cycle may severely injure the crop. (2) Under high soil moisture conditions prior to sorghum emergence. injury may occur following the use of Cycle. The crop will normally Qutgrow this effect. (3) Do not use Cycle on sor­ ghum grown under dry mulch tillage or injury may occur. (4) Do not make more than one preemergence application or preplant incorporated application per year. or illegal residues may result. (5) Do not apply to furrow-planted sorghum until furrows are leveled. (6) Deep planter marks or seed furrows should be leveled prior to application.

IMPORTANT: FOR TANK MIXTURES WITH BICEP OR AATREX (OR OTHER BRANDS OF ATRAZINE) - If applying Cycle in tank mix­ ture with AAtrex or Bicep. all the restrictions and rate limitations appearing on the AAtrex or Bicep label must be followed if more restrictive/protective than those on this label. In addition. if AAtrex or Bicep is/must be applied at rates lower than those recommended on this label. broad­ leaf weed control may be affected. Refer to the AAtrex or Bicep label for weeds controlled at the reduced rates. Precautions: . (1) APplications of Cycle + AAtrex or Cycle + Bicep on highly alkaline soils or on eroded areas where calcareous subsoils are exposed may cause sorghum injury. (2) If sorghum seed is not properly treated with Concep. Cycle + AAtrex or Cycle + Bicep may severely injure the crop. (3) Under high soil moisture conditions befor sorghum emergence. injury may occur following the use of Cycle + AAtrex or Cycle + Bicep. The crop wilrmally outgrow this effect.

Applications may be made early preplant, preplant surface, preplant incorporated or preemergence. For control of actively growing, emerged annual weeds that do not exceed 2 inches in height, a contact-type herbicide will generally not be required fo"r use with the Cycle plus Bicep tank mix­ tures. The use of a nitrogen solution or complete fertil­ izer solution in the spray or as the carrier will improve the burndown activity of the tank mixture. For weeds exceeding 2 inches in height, addition of a contact-type herbicide (e.g., Gramoxone Extra or Roundup) to the mixture is recommended in accordance with its label. For applications made less than 30 days before planting, apply one-half (1/2) the recommended rate of Cycle Alone in Table 3 for t"he given soil texture and organic matter content in tank mixture with one-half (i/2) the rate of Bicep Alone specified on the Bicep label . . For applications made 30-45 days before planting, the rate of Cycle and Bicep indicated above may be applied as a split treatment with 2/3 of the Cycle and Bicep rate applied initially followed by the remaining 1/3 at plant­ ing. Notes: (1) Tank mixtures of Cycle and Bicep as described above may provide less effective residual control of large seeded broadleaf weeds (e.g., velvetleaf and cocklebur) than Bicep applied alone at the full rate. (2) If peren­ nial broadleaf weeds are present at time of treatment, the addition of 2,4-D O~ Banvel to the tank mixture in accor­ dance with its label may improve performance. Tank Mixture of Cycle + AAtrex or Bicep with Gramoxone Extra or Roundup for Minimum-Tillage or No-Tillage Systems In minimum-tillage or no-tillage systems where sorghum (seed treated with Concep) is planted directly into a cover crop, stale seedbed, established sod or previous crop resi­ dues, the contact herbicides Gramoxone Extra or Roundup may be tank mixed with Cycle or Cycle + AAtrex or Cycle + Bicep. When used as directed, the Gramoxone Extra controls most emerged annual wellds and suppresses many perennial weeds.
