  • Microbial agents play an important role in the construction of a crop rhizosphere biological barrier to prevent the invasion of soil-borne pathogens, which has become a research hotspot in recent years. In order to provide a theoretical basis for the biological control of tobacco bacterial wilt in the future, field experiments were conducted to explore the effects of single and mixed application of three microbial agents on tobacco bacterial wilt.The results revealed that all the three kinds of microbial agents possessed a remarkable effect of controlling disease and promoting the growth of tobacco plants. When applied in the seedling transplanting period, Genjingkang, a recently developed microbial agent, effectively promoted the growth of the tobacco plants and controlled tobacco bacterial wilt, the overall control efficiency being more than 49%, while the addition of Bacillus polymyxa and Trichoderma harzianum compound agent further improved the control efficiency (>55%).
