  Rice blast, caused by the fungus Magnaporthe grisea, is the most serious disease of growing rice. It and bacterial leaf streak (caused by Xanthomonas oryzae pv. oryzae) are perennially the two worst rice diseases worldwide; they are both among the ten most important diseases of all crop plants. Other major rice diseases include sheath blight (caused by Rhizoctonia solani), false smut (Ustilaginoidea virens), and bacterial panicle blight (Burkholderia glumae). Viral diseases include rice bunchy stunt, rice dwarf, rice tungro, and rice yellow mottle.
