Another Revisitation of Using 2,4-D and Dicamba for Corn Weed Management: Application timing and rates matter
While doing some final weed control ratings this season, ears were pulled from plants in plots treated with 2,4-D, dicamba, and a standard Group 27 herbicide program pre-and-postemergence. Learn what impacts these herbicides had on the ear's size and appearance.
Perennial Weed Management in the Fall
