Apply Bicep II Magnam and Cinch ATZ only if field is planted with Concep-treated sorghum seed.These are formulated mixtures of 3.1 lb atrazine (a restricted-use herbicide) and 2.4 lb S-metolachlor/gal. Apply preplant and incorporate into the top 2 inches of soil before planting, or apply after planting but before sorghum or weeds emerge. In sensitive watersheds, atrazine best management practices suggest that soil surface applications at sorghum planting time should not exceed 1.0 lb/acre because of high potential for runoff losses. For a tank mix of Dual II Magnum and atrazine, follow directions on the Dual II Magnum label. Can injure sorghum on calcareous soils and should not be used on coarse-textured soils or other soils with less than 1% organic matter. The benoxacor safener in these products is specific to corn and does not safen these herbicides for use on sorghum. Use only Concep-safened forage or grain sorghum seed. No-till: Apply two-thirds of the recommended rate as a split treatment 30 to 45 days before planting and the remainder at planting. From 15 to 30 days preplant, a split application is preferred because it increases the chances of satisfactory activation by rainfall, but a single application is permissible. Can be tank mixed with paraquat or glyphosate.
