1. Only a few grains in the panicle are infected. Frequently, only a part of the grain is replaced by a black powder.

2. Sometimes, entire grain is also attacked and the black powder scatters on to other grains or leaves, and this is often the easiest way to detect the disease in the field.

3. The disease incidence is more on short duration varieties, planted early. Also avoid heavy doses of nitrogenous fertilizers.

4. Two sprays of Tilt 25 EC @ 200 ml in 200 litres of water/acre at 10% flowering stage and 10 days after should be given for controlling the disease.
