Bakanae disease

Symptoms:

This disease is also called white stalk, generally distributed where ever rice is grown. Infected seedlings are thin, chlorotic, may die before or after transplanting. In the field infected plants have few tillers and leaves die in short time. Live plants have empty panicles. Some infected plants may be stunted instead of elongated, while the abnormal elongation of these (infected) plants in seed bed or field is most common symptom of this disease.

Perpetuation:

The disease causing fungus is seed-and-soil-borne, through which it can survive for a long period.

Control:

1) Cultivation of resistant varieties

2) Seed treatment.
