Warrant herbicide is an encapsulated formulation of acetochlor herbicide and labeled for postemergence use in soybean. This study was designed to evaluate crop safety from various Warrant treatments and application timings including early preplant, preemergence, and postemergence. Early preplant and preemergence applications of Warrant are currently not labeled for use in soybean.
