[Objective] The paper was to explore the optimum dosage and application pattern of Trichoderma harzianum for controlling Potato Verticillium wilt.[Method] Two trials,sowing seed tubers in bacterial manure,sowing seed tubers in bacterial manure + root irrigation after seedling emergence,were conducted in the paper.[Result] T.harzianum could effectively control potato early dying and promote potato growth,thereby increasing potato yield.The control effects of sowing tuber in 300 times of bacterial manure + root irrigation with 300 times of conidia suspension after seedling emergence were ideal;the highest control effect and the highest saved yield loss were 72.60% and 33.33%,respectively.[Conclusion] The paper provides reference for field application of T.harzianum.
