Abstract: Taking strawberry variety Red Face as the research object, using Bacillus subtilis wettable powder, Trichoderma wettable powder, and composite microbial inoculants as the test materials, and 25% pyraclostrobin suspension as the chemical agent and water control, the control effects of 3 kinds of microbial agents on strawberry anthracnose, powdery mildew and gray mold and their influence on strawberry growth were studied. The results showed that the three microbial agents all showed good control effects on strawberry anthracnose, with the control effects exceeding 65%, and the treatment and control effects of the compound microbial agent was the most obvious; in the control of strawberry powdery mildew, the control effect of using Bacillus subtilis wettable powder was the most obvious, with a control effect of more than 60%, but the control effect of using Trichoderma wettable powder and compound microbial inoculants was poor, both below 40%; the three microbial agents all showed varying degrees of control effects on strawberry gray mold, with the control effect ranging from 30% to 55%. At the same time, the three microbial agents all had certain growth-promoting and yield-increasing effects on strawberry plants.
