Rhizoctonia solani has a wide host range among both monocotyledons and dicotyledons, causing what has been variously called sclerotial disease, banded sclerotial disease, banded sheath rot, sheath spot, sheath blight, sharp eye spot, oriental leaf, sheath blight, etc. The pathogen will form sclerotium, a compact mass of hardened fungal mycelium, at late stage on the surface of infected tissue.
