Management

• Use resistant variety.
• Avoid high use of fertility.
• In field spray with benomyl, fentin acetate.
• Folliar application of captafol, mancozeb and copper oxychloride also reduce severity of the fungas disease.
• To prevent pathogen survival across cropping season.
• Remove weeds.
• Plough under of rice stubbles.
