Most, but not all, soil residual herbicides can be applied after corn has emerged. Labels usually indicate a maximum corn growth stage beyond which applications should not occur. These growth stages can range from as early as two leaf collars to as late as 40-inch tall corn, so be sure to consult the respective product labels....More

Emerged weeds have the potential to reduce crop yield. Agronomists and weed scientists recommend using more soil residual herbicides at full use rates to take weed stress off non-residual postemergence herbicides by introducing multiple, effective modes of action, different chemistries and controlling weeds for longer periods of time before they emerge. This strategy is called the Overlap System....More

Weed resistance happens when a herbicide program relies on only one mode of action. This places extreme selection pressure on weed populations, which means a number of resistant weeds can survive the herbicide application, producing thousands of resistant weeds.
