Alternaria blight of mustard caused by Alternaria brassicicola is one of the most wide spread and destructive disease of rapeseed-mustard. To manage the disease - nutrients and fungicides were tested against Alternaria brassicicola, causing Alternaria blight of mustard. Efficacy of five nutrients were tested through foliar spray. Out of five, potassium proved to be most effective against Alternaria blight followed by copper in reducing per cent disease intensity. Efficacy of five fungicides viz. (azoxystrobin+hexaconazole), carbendazim + mancozeb, mancozeb, propineb and copper oxychloride were tested in in vitro conditions by poisoned food technique showed that (azoxystrobin + hexaconazole) was found most effective in inhibiting mycelial growth of Alternaria brassicicola at 200 and 300 ppm concentration followed by mancozeb. Foliar application of (azoxystrobin + hexaconazole) (0.1%) was found effective in reducing disease intensity.
