Southern blight of winged bean (Psophocarpus tetragonolobus (L.) DC.) occurred on Chichijima in Ogasawara (Bonin) Islands in 2011. A pathogen isolated from the diseased plant was identified as Sclerotium rolfsii Saccardo. An inoculation test confirmed that the fungus was the causal agent of the disease. This is the first report of the disease in Japan.
