Abstract
In Aug. 1978, Sclerotinia blight of soybean was found in southeastern Virginia, [USA] where soybean and peanut [Arachis hypogaea] are major field crops. S. minor was identified as the cause of blight in all but 1 soybean field, where S. sclerotiorum was the cause of disease. Pathogenicity tests demonstrated that both species of the fungus were virulent on soybean and peanut. Because of the sporadic incidence of Sclerotinia blight of soybean, the disease probably has little or no effect on soybean yield. The continued intercropping of soybean and peanut may increase its occurrence on both hosts.
