Abstract

Paddy is an important food crop of the world including India. Under field condition, the productivity of rice is affected by many biotic and abiotic factors. Among the different biotic constraints, diseases caused by fungal pathogens such as blast and sheath rot, grain discoloration are more frequent and ferocious disease in irrigated rice of both temperate and subtropical areas and which cause damage at all stages of crop growth. Blast, sheath rot and grain discoloration are major constrain of paddy production reported to cause extensive damage in crop production. An experiment was conducted to assess the Bio-efficacy of Thiophanate methyl 70% WP against blast, sheath rot and grain discoloration diseases of Paddy at ARS, Gangavathi. Results revealed that, among the various treatments evaluated, Thiophanate methyl 70% WP @ 1143 g/ha (T3) and Thiophanate methyl 70% WP @ 857 g/ha (T2) were found to be the best treatments to control blast, sheath rot and grain discoloration during both th
