Biology and Control of Ragweed Parthenium in Non-Cropland (SSAGR343/AG353)

Ragweed parthenium is considered a noxious weed in many parts of the world because of its allelopathic effect on other plants and the health risks it poses to humans. It causes allergic contact dermatitis, rhinitis, and respiratory problems in sensitive humans. Learn more in this 3-page fact sheet was written by D.C. Odero, B.A. Sellers, and J.A. Ferrell, and published by the UF Department of Agronomy, April 2011.

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.
