Information presented updates the First edition and discusses the current state-of-the-art relative to epidemiology and control of this peanut disease. No new research is reported. Technical Abstract: Sclerotinia blight, first observed on peanut plants in Argentina in 1922, is now present in most peanut-producing countries of the world. It was first observed in the United States in Virginia in 1971, thereafter spreading to North Carolina, Oklahoma, and Texas. By 1982, Sclerotinia blight was considered the most important disease of the peanut in Virginia and Oklahoma. Yield losses of 10% are common. In areas of fields showing severe symptoms of disease, 1,500-2,000 kg of pods per hectare often remain in the soil after harvest. In such fields, pod losses often exceed 50% of expected yield. |
