Abstract Background: The ginseng endophyte Paenibacillus polymyxa Pp-7250 (Pp-7250) have multifaceted roles such as preventing diseases, promoting growth, increasing ginsenoside accumulation and degrading pesticide residues, these effects still room for improvements. Composite fungicide is an effective means to improve the biocontrol effect of fungicide, but in combination with its symbiotic bacteria on needs be further researched, mechanism action remains elucidated. In order elucidate Bacillus cereus co-bacterial agent yield quality understory ginseng, well investigate action. Firstly, (BS), Pp-7250(PS) (PB) treatments yield, content, disease prevention degradation rate were evaluated by field experiments. Secondly, differences microbial communities rhizosphere soils different analyzed using high‐throughput amplicon sequencing. Finally, correlation analysis was performed PB improving ginseng. Results: results indicate that treatment improved accumulation, degradation. increased abundance beneficial microorganisms Rhodanobacter , Pseudolabrys Gemmatimonas Cortinarius Russula Paecilomyces Trechispora decreased pathogenic Ellin6067 Acidibacter Fusarium Tetracladium Alternaria Ilyonectria soil. enhanced function metabolic pathways, biosynthesis secondary metabolites, antibiotics, amino acids, carbon fixation pathways prokaryotes, DNA replication, terpenoid backbone biosynthesis, plant pathogen animal pathogen. This study provided a theoretical reference indepth research Conclusion: combined may potential promote resistance disease,
