Abstract:

In field evaluation of different fungicides against powdery mildew (Erysiphe cruciferarum Opiz ex. Junell) disease of mustard (Brassica juncea (L.) Czern. & Coss.) four sprays of hexaconazole at 0.005 per cent concentration starting from initial appearance of symptoms to twelve days interval recorded the least per cent disease intensity (28.17%) and maximum disease control (54.17%) which coincides with the highest seed yield of 2225 kg/ha as compared to no spray control with 30.04 per cent increase in yield. The next best effective fungicides were penconazole followed by difenoconazole, dinocap, wettable sulphur and azoxystrobin. The highest incremental cost: benefit ratio (ICBR) was obtained in four sprays of hexaconazole (1:4.63) followed by wettable sulphur 0.2 per cent (1:3.36) and penconazole 0.010 per cent (1:1.07). The maximum oil (34.37%), protein (18.05%) and 1000 seed weight (5.39 g) was also recorded in the treatment of hexaconazole (0.005%). The corresponding increase in oil, protein and 1000 seed weight were 11.95, 26.05 and 22.78 per cent, respectively.
