With any potentially resistant weed, frequent and timely scouting after a preemergence application helps retailers and their customers identify troublesome areas and formulate a timely postemergence herbicide plan. After postemergence applications, scouting allows retailers and farmers to identify at-risk fields where herbicide-resistant weeds may already exist and decide if it’s necessary to make a sequential herbicide application with an effective mode of action.

With two nonglyphosate modes of action, Sonic controls many broadleaf weeds early in the season. Sonic can be applied in the fall, preplant incorporated, preplant or preemergence up to three days after planting, before soybeans emerge.
