説明
Seasonal changes of lesions and mycelium distribution of sclerotial fungi on rice plants were investigated to clarify disease development during the growing season. In the tillering stage, several sclerotial fungi, Rhizoctonia solani AG2-2, R. oryzae, Sclerotium oryzae-sativae, S. fumigatum and S. hydrophilum were isolated from roots, non-elongation internodes and leaf sheaths of rice plants, and the isolation rate in lower leaf sheaths was higher than that in upper ones. At the mature stage, lesions formed by sclerotial fungi were distributed in upper leaf sheaths, and mycelia of each fungus were detected continuously from dead lower leaf sheaths to lesion-forming upper ones, regardless of lesion formation. These results suggested that sclerotial fungi penetrated into lower leaf sheaths at an early stage, and then infected upper leaf sheaths after the heading stage, forming typical lesions.
