1. The fungus affects the stem at earing and black lesions are produced on the sheath at water level.

2. Later on, the stem gets infected and rots leading to withering and lodging of the plant.

3. The incidence of this disease has declined on high yielding varieties due to improved cultural practices. Prefer to grow tolerant varieties of the Basmati group in the infested fields.
