Nematodes, non-segmented roundworms, can cause serious yield suppression in peanut production. This 10-page fact sheet written by Zane J. Grabau and Donald W. Dickson and published by the UF/IFAS Department of Entomology and Nematology explains how to recognize a potential nematode problem in a peanut production, confirm it with an expert, and choose the best management tools to control the problem.

This 10-page fact sheet summarizes the 2013 in-furrow and foliar fungicide programs for control of early and late leaf spot and white mold (southern stem rot) of peanut in Jay, Florida. It shows the effectiveness of 13 fungicide programs for disease control, as compared to no treatment. This data represents only one year and one location, and readers are cautioned that test results should be considered over several locations and years before final conclusions are valid. Written by Darcy E. P. Telenko, John Atkins, and Nick Dufault, and published by the UF Department of Plant Pathology, January 2014.
