Field experiment was conducted at the research plot of the Department of Plant Pathology, SHUATS, Prayagraj, U.P. during the rabi season of 2018-19 to test, “Efficacy of botanicals and Trichoderma viride against alternaria leaf blight (Alternaria brassicicola) of Mustard (Brassica juncea L.).” By foliar spray of certain plant extracts, bioagent and fungicide. The per cent disease intensity on leaves at 45, 60 and 75 DAS was recorded. Results showed that the Trichoderma viride @ 2% (fs) significantly reduced Alternaria blight, increased yield and cost/benefit ratio and was most effective treatment, followed by Garlic bulb extract 5% (fs), Neem leaf extract 15% (fs), Neem oil 2% (fs), Eucalyptus leaf extract 10% (fs), Dhatura leaf extract 10% (fs). However seed treatment with foliar spray of Trichoderma viride @ 2% most effective treatment have shown results at par with the foliar spray of Trichoderma viride in increasing the yield. The maximum plant height (cm) was recorded at Trichoderma viride (fs) @ 2% as compared to treated and untreated check.
