Abstract: Highest per cent increase in grain yield over unsprayed control was recorded in the spray schedule hexaconzole @ 0.1 per cent – hexaconazole @ 0.1 per cent (52.80)  followed by  carbendazim + mancozeb @ 0.2 per cent – wanis @ 0.5 per cent (28.80), hexaconazole @ 0.1 per cent – wanis @ 0.5 per cent (26.74), and carbendazim + mancozeb @ 0.2 per cent- carbendazim + mancozeb @ 0.2 per cent (24.61). Least per cent increase in grain yield over unsprayed control was observed in spray schedule wanis @0.5per cent- wanis @0.5 per cent (10.34). The highest B: C was obtained with spray schedule hexaconazole @ 0.1 per cent – hexaconzole @ 0.1 per cent (1:3.81) followed by hexaconazole @ 0.1 per cent – wanis @ 0.5 per cent and carbendazim + mancozeb @ 0.2 per cent – wanis @ 0.5per cent  both were recorded B:C (1:2.81). Most of the remaining spray schedules treatments, T4, T7, and T2 recorded next highest B: C of 1: 2.71, 1:2.69, 1: 2.43 and 1: 2.42, respectively. Least B: C of 1:2.18 was recorded in unsprayed control.
