Interpretive Summary:

Technical Abstract: Yield and grade of peanuts are adversely affected by several fungal pathogens, which cause several diseases in Oklahoma and other peanut producing states. These diseases are caused by pathogens that have a broad host range and are able to survive under adverse conditions for extended periods, sometimes for several years, by producing resistant structures. Continuous cropping favors the build-up of populations of soil pathogens to a level that can cause severe epidemics on an annual basis. In Oklahoma, the most economically important soil-borne diseases include Sclerotinia blight, Southern blight, pod rot, and diseases caused by root-knot nematodes. Chemical management of these diseases is often necessary and contributes to increased peanut production cost. Therefore, the ultimate goal of this research is to develop a management system for peanut production with minimum inputs (reducing number of fungicide and/or nematicide applications) for sustaining profitability under future farm commodity programs.
