Publications Available On Utilizing Site of Action Resistance to Fungicides, Herbicides and Insecticides

The University of Illinois Extension bulletins entitled, "Utilizing Herbicide Site of Action to Combat Weed Resistance to Herbicides" and "Utilizing Insecticide Mode of Action to Combat Insect Resistance to Insecticides” are now available for purchase. These publications establish a color-coded site-of-action classification system based on the various sites of action. This three-page bulletin is intended to enhance the ability of growers to rotate pesticides based on site of action to slow development of resistant biotypes. The front cover explains the importance of using a site-of-action classification scheme for resistance management. The inner table separates pesticides by site of action into "primary" colors. For example, herbicide chemical families sharing a particular site of action are coded in shades of the respective site-of-action family "primary" color. The bulletin also includes common and trade names of pesticides commonly used in agronomic production systems in the Midwest. Information on the back page of this bulletin varies. The herbicide publication includes corn and soybean herbicide premixes, with individual premix components coded with the appropriate color based on their respective site of action. While the insecticides publication goes into detail on how the different sites of action work.

These publications can be purchased for $2 each, or you can order one of each (insecticide, herbicide, and fungicide – when available) as a set for $5. For orders of 25 or more, the publications are $1 each plus the cost of shipping. Please email Kris Ritter at karitter@uiuc.edu or call 217-333-4424 to place an order.
