Abstract
Antagonism was evaluated among four grass and seven broadleaf herbicides applied postemergence for seedling and rhizome johnsongrass control in soybeans. Imazaquin and chlorimuron were most antagonistic to grass herbicides. Haloxyfop and quizalofop were least affected by the addition of broadleaf herbicides. Johnsongrass control was reduced 11 to 46% when grass herbicides were applied with broadleaf herbicides and were evaluated 3 and 12 weeks after treatment (WAT).Keywords
