Managing Against the Development of Herbicide-Resistant Weeds: Sugarcane (SSAGR244/SC077)

Although it is likely that small populations of herbicide-resistant weeds are already present in the Everglades Agricultural Area (EAA), herbicide resistance is currently not a significant problem. The continued use of integrated and properly managed weed control programs should ensure that resistance does not become a major issue in the future. In order to successfully manage herbicides against the development of herbicide-resistant weeds, you must have a basic understanding of which herbicides have the same site of action. This revised 4-page fact sheet lists herbicides by group number, site of action, chemical family, common name, and trade name.
