Abstract:
Under in vitro conditions, six fungicide combinations were selected with three different doses analyzed using the poison food technique. In which, Mancozeb 75 WP, Mancozeb 63% + Carbendazim 12% WP and Mancozeb 66.7% + Azoxystrobin 8.3% WP were found best in restricting the mycelium growth completely in all three doses. Under in vivo conditions, all the six selected fungicide combinations were significantly effective in controlling the intensity of Alternaria blight over control. The minimum% disease intensity was recorded for Carbendazim 50%WP @ 0.2%. While the highest 1000 seed weight and grain yield were recorded for Mancozeb 66.7% + Azoxystrobin 8.3% WP @ 0.05% with 3.88 g and 13.50 kg/ha respectively which is significant over all other treatments.
