Bacillus subtilis is a bacterial fungicide, which can inhibit a variety of pathogenic bacteria. Its mechanism of action is mainly through nutritional competition with a certain degree of site competition. The secretion of Bacillus sp. Has a certain inhibitory effect on some plant pathogens, but it is not the main inhibitory factor of plant pathogens. The field efficacy test results showed that the Bacillus subtilis WP had better control effect on cucumber powdery mildew, strawberry powdery mildew and gray mold. Dosage: 840~1260G/hm2 for cucumber powdery mildew (generally diluted with 50 ~ 60kg of water); 600~900g/hm2 for strawberry powdery mildew (generally diluted with 40 ~ 50kg of water); strawberry gray mold with 480~720g/hm2 (generally diluted with water 40 ~ 50kg). The method of use is a uniform spray. Beginning in the early stage of the disease, continuous spraying 2~3 times, usually 7 days interval spray 1 time,
