Author(s): Yogita Thakur and Sunil Zacharia

Abstract: Field experiment was conducted at the research plot of the Department of Plant Pathology, SHIATS, Allahabad, U. P. during the rabi season of 2014-15 to test, “Efficacy of Trichoderma spp. and garlic extract against Alternarial leaf blight of mustard (Brassica juncea L.)” by seed treatment and foliar spray of certain fungicides, plant extract and bioagents. Per cent disease intensity on leaves at 45, 60 and 75 DAS were recorded. Results showed that the foliar spray of Mancozeb63%+carbendazim12% (fs) significantly reduced Alternaria blight, increased yield and cost/benefit ratio and was most effective treatment, followed by seed treatment with Mancozeb63%+carbendazim12% 3g/kg, foliar sprays of Tricoderma viride (fs) 2%, Trichoderma harzianum (fs) 2%, seed treatment Trichoderma harzianum @ 2%. foliar spray of Allium sativam 10%. However seed treatment and foliar spray of Mancozeb63%+carbendazim12% most effective treatment have shown results at par with the foliar spray of Mancozeb63%+carbendazim12% in increasing the yield. The maximum plant height (cm) was recorded at Trichoderma viride (foliar spray) @ 2%
