Rice Blast

Fungal Diseases of Crops

A fungal disease (Magnaporthe oryzae) that produces diamond shaped lesions on rice leaves, stems and panicles and is considered the most destructive disease of cultivated rice worldwide. It is estimated to destroy enough rice each year to feed tens of millions of people, and the same fungus, in a host adapted form, also causes wheat blast, an emerging disease of growing concern in South America and South Asia.
