Cotton Tolerance to Dimethenamid-P, S-Metolachlor, and Acetochlor Preemergence and in Replant Situations

When growers make their first postemergence herbicide application, many find that certain spots of their field need to be replanted. Often, with this first application, there is a residual herbicide which could be dimethenamid-P, S-metolachlor, acetochlor, or others. So to evaluate the response of cotton to these herbicides in a replant situation studies were conducted with these herbicides applied prior to planting and cotton was planted following strip tillage or no-till. Additionally, response of cotton to preemergence applications of these herbicides was evaluated.
