This invention relates to the field of agricultural plant protection technology, specifically to an integrated pest management method for rapeseed suitable for aerial application, comprising the following steps: mixing Bacillus amyloliquefaciens Bam22 with imidacloprid and cyazofamid for aerial application; wherein, the Bacillus amyloliquefaciens Bam22 bacterial solution is diluted to a concentration of (2.5-5.0) × 10⁻⁶. 7 The dosage of cfu / mL was reduced to (6-9) g / mu for imidacloprid and (18-26) g / mu for boscalid. This invention achieves a synergistic effect by combining the pathogen-inhibiting effect of the Bam22 strain with the targeted control function of chemical agents. This significantly reduces the concentration of chemical agents and avoids pesticide damage from aerial spraying while ensuring that the efficacy of pest and disease control is not reduced. At the same time, the growth-promoting function of the Bam22 strain is used to restore the growth status of rapeseed, enhance the plant's stress resistance, and further ensure the yield and quality of rapeseed.
