Host: Oryza sativa L. (rice)Disease name: Rice blastPathogen name: Magnaporthe grisea (T. T. Hebert) M. E. Barr
Symptoms originate as small specks that enlarge into spindle-shaped lesions with reddish brown margins and gray centers. The lesions eventually coalesce, resulting in drying of the entire leaf. Symptoms are observed at all growth stages of the plant on all aerial parts, and the disease can be classified on the basis of the part infected: leaf blast, nodal blast, neck blast, and grain blast. Of the four, neck blast is the most destructive. The infected neck region breaks, causing the panicles of the plant to fall over and resulting in economic loss to the farmer.
