Successful weed control is one of the most important practices for economical soybean production in Florida. This 10-page publication discusses weed control methods for soybean growers. Written by J. A. Ferrell, G. E. MacDonald, and P. Devkota, and published by the UF/IFAS Agronomy Department, revised January 2021.
Successful weed control in peanuts involves use of good management practices in all phases of peanut production. This 11-page document lists herbicide products registered for use in Florida peanut production, their mode of actions group, application rate per acre and per season, and reentry interval. It also discusses the performance of these herbicides on several weeds under Florida conditions. Written by J. A. Ferrell, G. E. MacDonald, and P. Devkota, and published by the UF/IFAS Agronomy Department, revised May 2020.
Profitable sugarcane production in Florida requires effective weed management. Herbicides provide an efficient and cost-effective means of weed control, but excessive use of a single herbicide or group of herbicides with the same mechanism of action has resulted in the development of herbicide-resistant weeds. In crops such as sugarcane where a limited number of herbicides are registered, the loss of a single effective herbicide can be very costly. Thus, it is critical to manage herbicides in order to prevent or delay the development of herbicide-resistant weed populations. This 4-page fact sheet lists herbicides by group number, mechanism of action, chemical family, common name, and trade name. Written by D.C. Odero, B.A. Sellers, J.A. Ferrell, and G.E. MacDonald, and published by the UF Department of Agronomy, October 2014.
Cogongrass is found on every continent and is considered a weedy pest in 73 countries. In the U.S., cogongrass is found primarily in the Southeast. It was accidentally introduced into Alabama in the early 1900s, and purposely introduced as a potential forage and soil stabilizer in Florida (and other states) in the 1930s and early 1940s. However, soon after investigations began it was realized that cogongrass could be a weedy pest. Since its introduction, cogongrass has spread to nearly every county in Florida. In some cases, it has completely taken over pastures so that it is the only species present. This is a common thread where cogongrass invades; it quickly displaces desirable species and requires intensive management. This 5-page fact sheet was written by B. A. Sellers, J. A. Ferrell, G. E. MacDonald, K. A. Langeland, and S. L. Flory, and published by the UF Department of Agronomy, August 2012.
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.
