Root rot disease is one of the few fatal diseases in the cotton crop. Plants affected by this disease suddenly start drying up. The colour of the leaves turns yellow. Affected plants can be uprooted easily. The roots of the plants start rotting and turn brown and black.
Prevention: Destroy the plants affected by the disease. To save the crop from this disease, adopt crop rotation, and select varieties resistant to root rot disease. Seed treatment before sowing is very important.
For biological control, Combat (Trichoderma viride) at 8 gm/kg seed
or
Treat with Vitavax Power (Carboxin 37.5% + Thiram 37.5% WS) 3 gm/kg seed.
