Technical Abstract: Although the peanut acreage diminished in 2008 to 18,000 acres, the peanut crop remains a viable agricultural commodity in western and southwestern Oklahoma with an annual estimated value of $14 million. Production of peanut is adversely affected by soilborne pathogens, especially Sclerotinia minor, the causal agent of Sclerotinia blight disease. Besides Sclerotinia blight management, other important factors to consider for profitable peanut production in Oklahoma and the Southwest are to improve yield, grade, and oil quality (high oleic/linoleic ratio), and investigate avenues to reduce production inputs (i.e. reduce water consumption). Research has been directed to chemical management of S. minor on several hosts, including peanut and biological antagonists. Chemical management of Sclerotinia blight adds substantial cost to peanut production. Planting Sclerotinia-resistant cultivars is the most efficient and cost effective form of disease management available to growers. Efforts by peanut breeders and plant pathologists in the last 25 years were fruitful in developing several cultivars with resistance to Sclerotinia blight.
