Technical Abstract: Sclerotinia blight and other soilborne diseases adversely affect peanut health, productivity, and quality in Oklahoma and other peanut-producing states. These diseases are caused by pathogens that have broad host ranges and are able to survive under adverse conditions for extended periods, sometimes for several years, by producing resistant structures. These diseases are being manifested by continuous cropping of peanut. Continuous cropping favors build up of populations of soil pathogens to a level that reduces normal plant growth, development, and productivity. In Oklahoma, the most economically important soilborne diseases of peanut besides sclerotinia blight include southern blight, pod rot, verticillium wilt, and diseases caused by nematodes. Chemical management of these diseases is necessary, but it is costly and sometimes offers less than acceptable level of control. The ultimate goal of this research is to develop a management system for peanut production with minimum input for sustaining profitability under the 1996 farm commodity program. |
