Onion (Allium cepa L.) is the important vegetable crop. Under favourable condition onion is attacked by various diseases. Out of which, purple blotch is caused by Alternaria porri and is one of the predominant disease of onion. In the present studies, efficacy of bioagents, botanicals and fungicides were tested against Alternaria porri in vitro and toxigenic potential of Alternaria porri. Among the fungicides, Thiram+Carboxin and Propineb (0.3%) has shown 100% mycelial inhibition of Alternaria porri. Maximum mycelial inhibition of Alternaria porri was observed with Ocimum sanctum (60.83%) followed by Neem leaf extract. Among the bioagents tested, maximum mycelial growth inhibition of Alternaria porri was recorded with Trichoderma viride (85.45%) followed by Chaetomium globosum.
