Authority® Assist Herbicide
 Tough broadleaf weed control with added grass assistance
University studies show that in the absence of an effective soil residual herbicide, early-season weed competition can begin to reduce soybean yields as early as 10 days after crop emergence. Research studies show that Authority® Assist herbicide is effective in providing control of weeds as a soil foundation program.
Authority® Assist herbicide is a new premix product for soybeans. Combining multiple modes of action, it provides excellent control of glyphosate-resistant summer weeds like waterhemp, lambsquarters, nightshade, kochia, velvetleaf, Pennsylvania smartweed, morningglory, Venice mallow and many other broadleaves. It also offers good suppression of problem grasses like foxtails, fall panicum and nutsedges.
And, with its 4 lb per gallon SC formulation, Authority Assist has proven to be effective in no-till, minimum-till and conventional tillage systems using pre-plant surface, preemergence or preplant incorporated applications. Authority Assist has some foliar activity to provide burndown on emerged weeds. It offers a broader spectrum and excellent control when combined with 2,4-D, Rage™ D-Tech herbicide or glyphosate in no-till systems.
