Cabbage [Brassica oleracea var capitata (L.)] is an economically important cool season vegetable crop belongs to family Cruciferae. Alternaria leaf spot of cabbage caused by Alternaria brassicicola is the most destructive disease causing significant yield losses every year. In vitro evaluation were done with fungicides including the new generation viz., propiconazole, hexaconazole, tebuconazole, azoxystrobin each at three different concentrations (0.05%, 0.1%, 0.2%) and propineb, mancozeb, copper oxychloride at 0.1%, 0.2% and 0.4% concentrations respectively against the pathogen using poisoned food technique. The results revealed that propiconazole, hexaconazole, tebuconazole and copper oxychloride completely inhibited the mycelial growth of pathogen followed by mancozeb (0.1%), propineb (0.1%) and azoxystrobin (0.1%) by 51.1%, 50% and 27.7% respectively.

Keywords: Alternaria brassicicola, In vitro, Poisoned food technique
