Aside from rotating herbicide modes of action, there are several things producers can do to help prevent herbicide resistant weeds from taking hold. Use herbicides only when necessary. Use herbicides with multiple modes of action within the same year and on the same field. Whenever possible, use broad crop rotations that include 3 or 4 different crop species. Integrate mechanical control practices like rotary hoeing and cultivating.
Scout fields regularly and control escaping weeds as needed.
Clean tillage and harvest equipment before moving from fields or farms with known resistant weed problems.
