The bio-efficacy of seven popular fungicides viz., tricyclazole 45% + hexaconazole 10 WG,  tricyclazole 18% + mancozeb 62% , tricyclazole 75 WP , hexaconazole 5EC, mancozeb 75 WP, mancozeb 63%  WP + carbendazim12% WP and  cabendazim 50 WP were evaluated against rice blast (Pyricularia grisea) during kharif 2015 and 2016 under temperate agro-climatic conditions of  Kashmir.  Four foliar sprays of each fungicide at their recommended concentrations were separately applied. The first foliar spray of each fungicide was applied separately after appearance of disease, followed by two sprays at 10 to 15 days interval while last spay was applied at milk/dough stage of rice variety Kamad. Two years of experimentation revealed, that tricylazole 75 WP was most efficacious in management of disease and resulted in mean disease incidence of 27.00 per cent, mean disease intensity of 11.63 per cent, neck blast incidence of 8.35 per cent and a grain yield of 36.50 qha-1. Tricyclazole 45% + hexaconazole 10 WG was next in efficacy with mean disease incidence, intensity and neck blast incidence of 32.41, 14.34 and 11.62 per cent and a grain yield 35.10 qha-1, respectively. Tricyclazole 18% + mancozeb 62%; mancozeb 63% WP + carbendazim12% WP; carbendazim 50 WP and hexaconazole 5 EC resulted in disease incidence of 35.62, 36.9 37.75 and 47.79 per cent,  mean disease intensity of 16.62, 20.11, 23.45 and 29.06 per cent while mean neck blast incidence was 14.35, 17.37, 19.62 and 21.80 per cent with a consequent grain yield of 34.00,  33.20, 32.75 and 30.20 qha-1, respectively. Mancozeb 75 WP was found least efficacious and resulted in highest mean disease incidence, intensity, neck blast incidence and lowest grain yield of 56.12, 41.01 and 25.55 per cent and 28.25 qha-1, respectively. However it was significantly superior than the untreated control where mean disease incidence, intensity, neck blast incidence and grain yield was 91.12, 57.40 and 35.55 per cent and 21.75 qha-1, respectively.
