An experiment on evaluation of five most effective fungicides viz., azoxystrobin 23% SC (Onestar), kasugamycin 3% SL (Kasu-B), flusilazole 40% EC (Cursor), carbendazim 50% WP (Dhanustin) and metiram 55%+ pyraclostrobin 5% WG (Carbrio Top) against A. brassicicola causing leaf spot in cabbage in vitro at 250 and 500 ppm as well as in field in pots receiving two sprays of 0.05 per cent concentration in rabi season was conducted. Among them flusilazole 40% EC was highly efficient as it inhibited 100 per cent mycelial growth of A.brassicicola at both the concentrations. Per cent disease index was found minimum after application of flusilazole 40% EC. All the fungicides were superior over control in increasing the yield of cabbage per pot. The maximum weight of head (410 g) was recorded after foliar application with flusilazole 40% EC (C). This investigation will be helpful to farmers in manageing Alternaria leaf spot of cabbage.
