In practical applications, the effectiveness of biological control agents such as is often unstable due to different soil environments. Herein, we aimed to explore the control effect and intrinsic mechanism of in black soil and red soil in combination with tomato Verticillium wilt. application effectively controlled the occurrence of Verticillium wilt in red soil, reducing the incidence by 19.83%, but played a limited role in black soil. colonized red soil more efficiently. The pathogen decreased by 71.13% and 76.09% after the application of combinations in the rhizosphere and bulk of the red soil, respectively, while there was no significant difference in the black soil. Additionally, application to red soil significantly promoted phosphorus absorption. Furthermore, it significantly altered the bacterial community in red soil and enriched genes related to pathogen antagonism and phosphorus activation, which jointly participated in soil nutrient activation and disease prevention, promoting tomato plant growth in red soil. This study revealed that the shaping of the bacterial community by native soil may be the key factor affecting the colonization and function of exogenous .
