ABSTRACT
This chapter provides information on diseases of mulberry Rice - Oryza sativa L., their symptoms, pathogen characters, epidemiology, and management. The diseases covered are brown spot, sheath rot, sheath blight, stem rot, false smut, udbatta, stackburn, narrow brown leaf spot, foot rot, grain discolouration, bunt, leaf smut, leaf scald, bacterial blight, bacterial leaf streak, rice tungro disease, rice grassy stunt disease, rice ragged stunt disease, rice dwarf disease, white leaf disease, rice yellow dwarf disease, ufra disease, and khaira disease. Sheath rot disease was first identified by Sawada from Taiwan in 1922 and later it became a common problem in Japan. Sheath rot is present in most of the rice growing countries worldwide, particularly in rainfed rice ecosystems and is more prevalent during wet than dry seasons. The genus Sarocladium was established in 1975. It is a saltatory morphological apomorph. No teleomorphs are known to be associated with the small group. The fungus produces whitish, sparsely branched, septate mycelium.
