Abstract ：Antagonist strain MT-06 was isolated from the soil strawberry root. This paper was to study the antagonism between several common pathogen antagonisms and strain MT-06. The result indicated that right Fusarium oxysporum, Zhejiang Fritillaria alternaria, safflower blight, the fungus watermelon, tomato late blight bacteria and Pumpkin hyphae of the fungus growth were significantly inhibited by strain MT-06. In addition, this paper sheds on the strain of greenhouse strawberries and prevention of powdery mildew. The result of greenhouse strawberries experiments, which was designed to prevent powdery mildew, indicated that the effect was significant after 7 days application of the strain MT-06. This effect was just lower than using pharmaceutical Tsui Pui 50% Dry Suspension. After 14 days application of the strain MT-06, the prevention effect was more significant than using the Pharmacy cui Pu 50% dry suspension. The result of two tests showed that air humidity has a direct impact on the occuring frequency of strawberry powdery mildew. Air humidity environment could increase the occuring frequency of strawberry powdery mildew. Antagonist MT-06 had excellent prevention ability upon strawberry powdery mildew, especially more better than genenral fungicides.
