If the farmers are unable to take proper steps to prevent this disease, then the entire crop becomes diseased in 3 to 4 days and there is a complete possibility of crop failure. The disease begins in 30-35 days. Initially, brown dots are found on leaves and branches, and over time the entire plant becomes dry brown in colour.
