Sheath blight of rice

A rice leaf exhibiting typical watermark lesions associated with sheath blight disease

Rice-sheath blight is a disease caused by Rhizoctonia solani (teleomorph is Thanetophorus cucumeris), a basidiomycete, that causes major limitations on rice production in India and other countries of Asia.[1] It is also a problem in the southern US, where rice is also produced.[2] It can decrease yield up to 50%, and reduce its quality.[3] It causes lesions on the rice plant, and can also cause pre- and post-emergence seedling blight, banded leaf blight, panicle infection and spotted seed.[4]
