Control of pervasive row crop weeds with dicamba and glufosinate applied alone, mixed, or sequentially

Abstract Dicamba and glufosinate are among the few effective postemergence herbicides to control multiple herbicide-resistant weeds in southeastern U.S. cotton soybean production. Field studies were conducted determine effect of weed size application dicamba individually, mixed, or sequentially on common ragweed, goosegrass, large crabgrass, ivyleaf morningglory, Palmer amaranth, sicklepod control. Sequential herbicide treatments applied 7 d after initial treatment. The tested sizes predominantly did not affect Control broadleaf species with sequential applications never increased compared application. Two and/or + controlled grasses better than one order control, whereas was important for grass weeds. Grass higher when before dicamba. additively weeds, except which less alone. results experiment provide evidence that row crop found United States, but present may dictate how together.
