The application method of choice will depend on the anticipated weed spectrum and the preference of the applicator. When lMAZAQUINIlMAZETIMPYR DG is applied to the soil, susceptible weeds emerge, growth stops, and then the weeds either die or are not competitive with the crop. When lMAZAQUINIlMAZETIMPYR DG is applied postemergence, absorption occurs through both the foliage and roots. Susceptible weeds stop growing and either die or are not competitive with the crop. A timely cultivation may aid in the control of certain weeds or improve general weed control when adequate moisture is not received after application. Cultivation should be shallow After postemergence treatments. wait at least 10 days before cultivating. The mode of weed killing activity involves uptake of IMAZAQUrNlIMAZETHAPYR DG by weed rvots andlor foliage and rap:d translocation to growing points. Therefore, adequate soil moisture is important for optimum lMAZAQUINIlMAZETHAPYR DG activity. The amount of rainfall or irrigatio" required following application depends on existing soil moisture, soil texture and organic matter content. Sufficient water to moisten the soil to a depth of 2 inches is normally adequate. If ~dequate moisture is not received within 7 day, after treatment, then a culti,ation or postcmergence herbicide application may be needed to improve weed control. When adequatc moisture is received after dry conditions, IMAZAQUINIIMAZFTHAPYR DG will provide residual control of susceptible gerrrinating weeds; activity on established weeds will depend on the weed species and the location of its root system in the soil. Occasionally, internode shortening of soybean pl,,,.;s may be (observed with IMAZAQUrNl:MAZETHAPYR DG applications. This has no effect on soybean yields. Following the use of this product and chemically related products with the same mode of action, naturally occurring biotypes' of some of the weeds listed on this label cannot be effectively controlled by this and related products. This product should be tank-mixed or appiied sequentially with an appropriate registered herbicide having a different mode of action to ensure control of resistant biotypes . • A weed biotype is a naturally occurring individual within a given species that has a slightly different. but distinct genetic makeup from other individuals. See your Cyanamid representative for additional information. PRECAUTIONS DO NOT use on crops other than soybeans. Crops other than soybeans, such as cotton, corn and vegetables, may be injured by spray drift or other indirect cotjtan with IMAZAQUrNlIMAZETHAPYR DG. · . • • • To avoid injury to sensitive crops from spray drift, follow all use di;e,ctions and prec~utions in SPRAYING rNSTRUCTIONS on pages 18 & 19. ' •• •. • • · . ~ DO NOT use IMAZAQUINIIMAZETIIAPYR DG other than tn arrordance .witP the instructions set forth on this label. To avoid injury to sensitive cmps, spray equipment used for IMAZAQUIN/IMAZrn,APYR DG applications must be drained and thoroughly cleaned with water before being used to apply other products to these crops. Sec pages 20 & 21 for ROTATIONAL CI<.OP RESTRICTIONS. -6- 9/94 c PROPOSED IMAZAQUINIlMAZETHAPYR DG LABEL IMAZAQUINlIMAZETHAPYR DG should be made before soybean bloom. There must be an interval of at least 90 days between the last IMAZAQUINIIMAZETHAPYR DG application and soybean harvest. DO NOT graze or feed treated soybean forage, hay or straw to livestock. Use of IMAZAQUINIIMAZETHAPYR DG herbicide in accordance with label directions is expected to result in normal growth of rotational crops in most situations; however, various environmental and agronomic factors make it impossible to eliminate all risks a'soeiated with the use of this product and, therefore, crop injury, is always possible. See pages 20 & 2 I for ROTA TIONAL CROP RESTRICTIONS. Replanting: If replanting is neces>ary In a field previously treated with IMAZAQUIN/IMAZETHAPYR DG, the field may be replanted to soybeans. Rework the soil no deeper than the treated zone. DO NOT apply a second treatment of IMAZAQUINIIMAZETHAPYR DG. -7- 9/94 • J ~ -. / ,.~ .f.:;, I PROPOSED IMAZAQUIN/IMAZETHAPYR DG LABEL USE AREA IMAZAQU1NllMAZETHAPYR DG can be applied only in the stales or parts of stales shaded in the following map: USE REGION 1 includes easlem Oklahoma, Arkansas, Ihe Missouri bnolheel, Tennessee, Nonh Carolina, South Caro!ina, Georgia, Florid", Alabama, Mississippi, Louisiana, and eastern Texas.

Avoid deeper incorporation or reduced weed control andlor crop i~jury mal result. lMAZAQUlNllMAZETHAPYR 00 may be applied immediately before planting or up to 45 days (30 days in Use Region I) prior to planting. If soybeans are planted on bed;, apply and incorporate after bed formation using PTO-driven equipment or rolling cultivator. Maintain lMAZAQUlN/lMAZETHAPYR DG in the surface I to 2 inches of the finished beds. PREPLANT AND PRE EMERGENCE SURFACE APPLICA TJONS (including no-till) Apply IMAZAQUINIlMAZETHAPYR DG up to 45 days (30 days in Usc Region I) before, during or after planting but before the crop emerges. As with other herbicides applied preemergence, rainfall or irrigation is necessary to activate IMAZAQUINIlMAZETHAPYR DG in the soil. If sufficient rainfall or irrigation to activate IMAZAQUIN/1MAZETHl.PYR DG is not received within 7 days after application, a thorough shallow tillage, cultivation, or postemergence treatment may be required for control of emerged weeds. POSTEMERG ENCE A PPLICA TIONS IMAZAQUINIlMAZETHAPYR DG is effective in controlling weeds in conservation tillage as well as :n conventional production systems. Apply IMAZAQUINIlMAZETHAPYR DG herbicide as an early postemergence treatment when weeds are actively growing and before they exceed a height of 3 inches, unless otherwise mdicated. Delay application until the majority of the weeds are at the recommended growth stage. Application timing should be based on weed size and not crop growth stage IMAZAQUINIIMAZETHAPYR DG applied post emergence not only controls the emerged weed speci" listed previously, but can also provide residual control of susceptible weeds that may emerge after .:.pplication. Application should be made to small soybeans so more herbicide reaches the soil surface. The level of residual contrf'! wi'! depend on weed density and canopy closure which affect the a'l,ouni of iMAZAQUlNllMAZETYAPYR DG reaching the soil surface and environmental conditions, such as ramfall, at the time of and following application. . ..• Apply IMAZAQUlN/IMAZETHAPYR DG to crops and weeds that are actively growing.

ADJUVANTS , ADDITION OF SURF ACT ANTS: Use a non-ionic or organo-silicone surfactant The nonionic surfactant should contain at least 80% active ingredient and should be applied at a rate of 2 pints per 100 gallons of spray mixture, The organo-silicone surfactant should be applied at a rate of at least I pint per 100 gallons of water, Refer to the specific surfactant label for more specific use instructions. OR CROP OIL CONCENTRATE: Instead of a surfactant, a petroleum or vegetable seed based oil concentrate (such as SUN-IT Ill) may be used. SUN-IT II is recommended when weeds -'are under moisture or temperature stress. Use SUN-IT II or other methylated seed oils at the rate of 1,5 to 2 pints per acre (use the higher rate when weeds are at the maximum label size), or use a crop oil concentrate at 2 pints per acre, AND II. LIQUID FERTILIZER SOLUTION Recommended nitrogen based fertilizers include liquid fertilizers (such as 28%N, 32%N or 10-34-0) at the rate of 1-2 quarts per acre, Use the higher rate when weeds dre under moisture or temperature stress, Instead ofa liquid fertilizer, spray grade ammonium sulfate may be used at the rate of2,5 Ibs per acre, Note: Liquid fertilizer solutions are not required in IMAZAQUINIlMAZETHA.PYR DG applications in use areas south of Interstate highway 40. There must be an interval of at least 90 days between t',e last IMAZAQUIN/IMAZETHAPYR DG application and soybean harvest. IMAZAQUIN/IMAZETHAPYR DG should be applied a minimum of one hour before rainfall or overhead irrigation.

GRASS WEEDS ! POST APPLIED COMBINA TIONS IMAZAQUIN/lMAZETHAPYR DG may be tank mixed with selective postem~rgence grass herbicides registered for use in soybeans such as Select 7, Poast Plus8, Fusilade 2000 9, Fusion9, Assure lO or Option I 1 These seltctive grass herbicides may also be applied following a soil application and prior to or following a post application of lMAZAQUINIIMAZETI-lAPYR DG. For best results use SUN-IT II or a crop oil concentrate AND liquid fertilizer with grass herbicide tank-mixtures. In some cases the activity of the grass herbicide may be reduced when mixed with IMAZAQUINIlMAZETHAPY;, DG. The reduction in activity may be overcome by delaying the application of the postemergence grass herbicide 7 days following the application of lMAZAQUINlIMAZETHAPYR DG. If the grass herbicide is applied first, wait 3 days before applying IMAZAQUINlIMAZETHAPYR DG. Refer to the respective grass herbicide label for recommended application rate, weed size and restrictions.
