 ABSTRACT

Alternaria leaf spot of cabbage caused by Alternaria brassicicola is one of the most destructive disease of cabbage (Brassica oleracea var. capitata) causing both quantitative as well as qualitative losses all over the kerala. The disease is difficult to manage alone with fungicides or bioagents. Hence the present study was undertaken to manage the disease effectively by utilization of fungicides, bioagents and their combinations. The results from in vivo assay showed that lowest per cent disease index was recorded with the treatment hexaconazole + B. subtilis (10.8%) and the disease suppression over control was 79.4%. This was followed by hexaconazole (16.6%) which was on par with tebuconazole (18.3%) and propiconazole (19.1%). Maximum yield was recorded with the treatment hexaconazole + B. subtilis (0.58 kg/plant) followed by hexaconazole (0.54 kg/plant), tebuconazole (0.52 kg/plant) and propiconazole (0.48 kg/plant).

Key words: Alternaria, Tebuconazole, Propiconazole, Hexaconazole,
