To identify the pathogenic fungus that caused peanut southern blight in Jingzhou City of Hubei Province, the pathogens of peanut southern blight were isolated, purified and identified using the methods of tissue isolation, morphological identification, and molecular identification, which is based on ITS. The pathogenic fungi (QZ) that caused peanut southern blight were identified as Athelia rolfsii, which belonged to the subphylum basidiomycete fungus.
