Apply herbicides in tank-mixed, prepackaged, or sequential mixtures that include multiple sites of action. Both herbicides must have substantial activity against potentially resistant weeds for this strategy to be effective. Planting new herbicide-resistant crop varieties should not result in more than two consecutive applications of herbicides with the same site of action against the same weed unless other effective control practices also are included. Combine, where feasible, mechanical weed control. Where soil erosion potential is minimal, include primary tillage as a component of the weed-management program.
Scout fields regularly and identify weeds present.
Respond quickly to changes in weed populations to restrict the spread of weeds that may have been selected for resistance. Clean tillage and harvest equipment before moving it from fields infested with resistant weeds to those that are not. Resistant weeds for TVC areas could spread to cropland.
