ROLE OF ADJUVANTS ON SULFONYLUREA HERBICIDE EFFICACY. D. Sanyal*1, P. C. Bhowmik2; 1Monsanto Company, St. Louis, MO, 2University of Massachusetts, Amherst, MA (169)
Sulfonylurea herbicides kill weeds by inhibiting acetolactate synthase, an enzyme required for cell growth. They work on a range of grasses and broadleaf weeds. Previous studies have been conducted to identify the proper adjuvant systems to obtain optimum activity of sulfonylurea herbicides. The impact of adjuvant varies among the weed species and growth stages. This presentation will review the effect of various adjuvants on sulfonylurea herbicide activity from published literature.
