As weed resistance is increasing and weed characteristics are changing, weed management strategies have to change. That’s why agronomists and weed scientists recommend using more than one soil herbicide. This strategy, called the Overlap™ System, takes weed stress off post herbicides by introducing multiple effective modes of action, different chemistries and controlling weeds before they emerge for longer periods of time.
We recently spoke with Nick Hustedde of FMC Corporation about the system who says it is designed to address resistant weeds that have long emergence patterns. “That overlap program encompasses several different products from FMC for soybeans and corn that fit in the strategy,” said Hustedde.
The Overlap System involves: (1) applying strong residual herbicides preplant or preemergence to control weeds early in the season (2) following that application with an early postemergence herbicide that features a different mode of action.
