A new disease of cymbidium was found in Japan in the prefectures of Yamanashi, Shizuoka, Kochi, Shiga, Saitama and Yamaguchi from 1992 to 1998. Dark brown to black lesion appeared on the base of the leaves, dry rot was seen on pseudobulb and rot was seen on roots. Disease progress was slow, so that the plant grew up suppressively. The causal pathogen was identified as Fusarium solani on the basis of its morphology, and the common name of the disease, dry rot, was proposed.
