Abstract
Diseases damage to rice can seriously break productivity and with in short time destroys the crop. Screening of various groups of fungitoxicants in solo and in combination against major diseases of rice was carried out during summer and Kharif 2019. The pooled data revealed Fenoxanil 20% SC + Isoprothiolane 40% EC @ 2ml L-1 was effective in reducing the disease severity of leaf blast and neck blast by recording least percent disease index (PDI) of 13.33 and 12.22 with yield of 5099 kg ha-1as against 40.74 and 48.89 and yield 4034 kg ha-1 in control respectively. The combi fungitoxicants Azoxystrobin 25% SC + Hexaconazole 5% 16.25% SC @ 900 ml ha-1 and Kresoxim methyl 40% + Hexaconazole 8% WG @ 500 g ha-1 were effective against leaf blast, neck blast, sheath blight and sheath rot with PDI 9.25,10.40 13.33 and 17.77 respectively . The tank mix of Hexaconaxole 75% WG and Isoprothiolane 40% EC @ 66.7 g + 750 ml ha-1 was effective against leaf blast, neck blast, sheath blight and sheath rot with least PDI of 2.59, 6.33, 4.81 and 6.85 respectively. Kresoxim methyl 40% + Hexaconazole 8% in combination with Isoprothiolane 40% EC @ 500 g + 750 ml ha-1 recorded the reduced PDI of 4.81, 4.29, 11.85 and 11.11 for leaf blast, neck blast, sheath blight and sheath rot respectively .The fungitoxicants evaluated did not cause any phytotoxicity.
