Abstract
From 2004 to 2005, the stem rot of Disporum sessile D. $D_{ON}$ caused by Sclerotium rolfsii occurred spoyadieally in an herbs exhibition farm of Hamyang, Gyeongsangnam-do Agricultural Research and Extension Services, Korea. The typical symptom is water-soaking, dark brown on the stem and rotting, wilting. The infected plants were mostly died. White mycelial mats were spread over lesions, and then sclerotia were formed on stems and near soil line. The sclerotia were globoid in shape, 1$\sim$3 mm in size and white to brown in color, The optimum temperature and sclerotia on PDA was 30$^{\circ}C$ and the hyphal width was $3{\sim}10{\mu]m$. The typical clamp connections were observed in the hyphae of the fungus grown on PDA. Pathogenicity of the causal organism was proved on D. sessile according to Koch's postulate. On the basis of mycological characteristics and pathogenicity to host plants, this fungus was identified as Sclerotium rolfsii Saccardo. This is the first report on the stem rot of D. sessile caused by S. rolfsii in Korea.
