Abstract: Early (Alternaria solani) and late blight (Phytophthora infestans) are very destructive diseases which cause heavy economic yield loss of potato. The early and late blight diseases of potato appear every year in varying intensity and cause heavy yield losses in potato tuber. An experiment was conducted at Main Experiment Station (MES) of Vegetable Science, Narendra Deva University of Agriculture and Technology, Kumarganj, Faizabad during Rabi Season of 2011-2012. Seven treatments including control i.e. T1 (Control), T2 (Tuber treatment with Trichoderma viride @ 8g/kg at planting), T3 (Tuber treatment with Bacillus subtilis @ 0.25 per cent at planting), T4 (Tuber treatment with spray of Boric acid @ 3 per cent before storage), T5- Bio-fumigation (mustard were sown at least one month before potato planting and used as green manure), T6 (Bleaching powder @ 12 kg/ha with fertilizer at the time of planting) and T7 (Gypsum application @ 200 kg/ha at the time of planting) with four replications were taken up using RBD. The maximum plant emergence (88.00%) was recorded with T5. Minimum disease intensity (10.05 and 34.14%) was recorded with T2 against early and late blight of potato as compared to T1. Maximum tuber yield (225.83 q/ha) was also recorded with T2 as compared to T1. Trichoderma viride was most effective in reducing the disease intensity and increasing tuber yield
