Biocontrol agents transform the stability and functional characteristics of the grape phyllosphere microenvironment

The spread of grape leaf diseases has a negative impact on the sustainable development of agriculture. Diseases induced by significantly affect the quality of grapes. biocontrol agents have been proven effective in disease management. However, limited research has been conducted on the impact of biocontrol agents on the assembly and potential functions of plant phyllosphere microbial communities. This study used high-throughput sequencing combined with bioinformatics analysis and culture omics technology for analysis. The results showed that biocontrol bacteria utilized in this study can significantly reduce the disease index of powdery mildew (
