The stem rot of Broccoli (Brassica oleracea var. italica Plenk) caused by Sclerotinia sclerotiorum (Lib.) de Bary is increasingly drawing attention as a destructive disease. Intensive use of fungicides for protection of crops from disease is not only injurious to human health but also polluting the environment. The effect of different bio-agents was evaluated against stem rot of broccoli caused by Sclerotinia sclerotiorum as an alternate approach to manage the disease. Different fungal and bacterial bio-agents were isolated from sclerotia of test organisms and rhizosphere of broccoli and tested against the fungus. Among them fungal bio-agent Coniothyrium minitans formed maximum inhibition zone (16 mm) while bacterial bio-agents Pseudomonas fluorscens created minimum (10 mm) inhibition zone in in vitro. In field experiments minimum disease incidence was observed with Coniothyrium minitans followed by Trichoderma viride, whereas rest of the bio-agents proved least effective.
