Abstract： To explore effective technological paths for green prevention and control of tobacco bacterial wilt disease，address the over-reliance on chemical pesticides and promote green sustainable development in the tobacco industry， this study implemented an integrated“grain-tobacco integration” model in Shiyuan village，Pengshui county， Chongqing. Firstly，the research introduced crop rotation （tobacco/potato） disrupted pathogen cycles. Additionally，we systematically integrated green technologies such as disease resistant variety screening， biological control （antagonistic microbial agents），soil improvement （organic fertilizer combined with microbial agents），and healthy cultivation management. We， finally，constructed a comprehensive prevention and control system with ecological regulation as the core and multi technology collaboration. The field test results showed that，compared with conventional control，the technology significantly reduced the incidence rate of tobacco bacterial wilt disease by 31.38% ，increased the yield of tobacco leaf over 26% ，and advanced the soil Chaol index by 39.86% .Research demonstrates that the integrated grain-tobacco management model， through optimized farmland ecology and enhanced system resilience，achieves effective ecological control of tobacco bacterial wilt disease. This approach delivers triple benefits in economic，ecological，and social dimensions. This study provides technical support for promoting green plant protection in wul. 1 ing Mountain area and similar tobacco-growing areas.
