| Abstract/Contents: | "Incidences of herbicide-resistant weed biotypes continue to increase in Illinois agronomic production systems. Several different management approaches have been proposed to reduce the selection for herbicide-resistant weed biotypes, but virtually all suggest rotation of herbicide modes of action as a critical element. While this recommendation is valid, the lack of uniformity which exists in selection of herbicide mode of action families, coupled with nonuniform placement of individual herbicides into these families, can result in confusion at the producer level. Classification of herbicides by their respective sites of action may allow for more consistent herbicide rotation and may prove to be more reliable to delay the onset of herbicide-resistant weed biotypes. The Weed Science Society of America (WSSA) and the Herbicide Resistance Action Committee have each developed classification schemes based entirely on herbicide site of action. We have adapted the WSSA herbicide site of action classification scheme described by Retzinger and Mallory-Smith (Weed Technol. 11:384-391) into a color-enhanced bulletin targeted to producers and herbicide applicators. The University of Illinois extension bulletin, "Utilizing Herbicide Site of Action to Combat Weed Resistance to Herbicides" establishes herbicide site of action classification based on 14 sites of action, with each individual site of action coded with a distinct "primary" color. 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 herbicides commonly used in Illinois agronomic production systems. The back page of this bulletin includes corn and soybean herbicide premixes, with individual premix components coded with the appropriate color based on their respective site of action. The intention of this bulletin is to enhance the ability of growers to rotate herbicides based on site of action to slow further development of herbicide-resistant weed biotypes." |
