Rice sheath blight fungus, Rhizoctonia solani (IA), was isolated at the rate of 100% from the mature rice plants having many sheath blight lesions. However, from the diseased samples of sheath blight like lesions, Sclerotium oryzae-sativae was isolated at the rate of 70%. High isolation rate of S. hydrophilum was observed in the plants with many sheath blight lesions, but R. oryzae was detected more often in the plants with sheath blight like lesions. S. hydrophilum and S. oryzae-sativae were frequently isolated from lesions near the basal parts of the plants.
