Tolerance & Weed Shifts
 
 
COST OF RESISTANCE


Herbicide-resistant weeds force production system changes that increase crop production costs, may require additional herbicide applications or tillage passes, and lead to yield and profit losses. By the time weed resistance is recognized in the field and identified, it is already well established. Researchers estimate that about 30 percent of the weed population is resistant by the time it’s recognized in the field. This requires serious intervention.
