Abstract

Incidences of herbicide-resistant weed biotypes continue to increase throughout the Midwest. Management approaches to reduce the selection of herbicide-resistant weed biotypes include rotating herbicides based on modes or sites of action. The University of Illinois Extension bulletin, "Utilizing Herbicide Site of Action to Combat Weed Resistance to Herbicides," establishes a classification based on 14 sites of action with each individual site of action coded with a distinct "primary" color. This bulletin is intended to enhance the ability of growers to rotate herbicides based on site of action to slow further development of herbicide-resistant weed biotypes.
