Foliar and soilbome fungal disease are significant profit-limiting constraints for peanut production in Florida and the southeastern U.S. Current management strategies are effective for most diseases, but improved strategies and continued disease monitoring are needed for optimal peanut production. The integration of cultural and chemical disease management strategies is critical for determining optimal management system for producers. Disease resistant cultivars and fungicide spray frequencies have been found to affect losses from early leaf spot ( Cercospora arachidicola ), late leaf spot ( Cercosporidium personatum) and stem rot/white mold (Sclerotium rolfsii). Results from this study indicate the importance of cultivar selection in determining chemical management strategies. The data also indicates that in certain situations increased spray numbers do not consistently lead to increased profits.
