ALTERNARIA BRASSICICOLA INCITED LEAF SPOT OF OIL-SEED BRASSICAS OF KALYANI AND ITS CONTROL
Seeds of yellow sarson and brown sarson carry A. brassicicola and treatment of seeds with ED50 doses of blitox, copper sulphate, ziride, and dithane M-45 eradicated the pathogen from the seeds. A total of 18 species of fungi were isolated from the phylloplane of mustard including A. brassicicola. Leaf surface saprophytes Cladosporium cladosporoides, Penicillium variable and P.sp. isolate B-2 were inhibitory to A. brasicicola in vitro.
