Management of alternaria blight through genotypes, fungicides, bio-agents and botanical in rapeseed-mustard

Alternaria blight caused by Alternaria brassicae (Berk) Sacc. and A. brassicicola (Schw) Wiltshire is one of the most common and destructive disease of rapeseedmustard. The experiments were conducted under field condition to develop effective management strategies for this disease through evaluation of genotypes for resistance and application of fungicide, bio-agents and botanical.
