摘　　要：为验证荧光假单胞杆菌PF7-5对烟草角斑病的生物防治效果,设计了荧光假单胞杆菌PF7-5对烟草角斑病菌的室内和大田抑菌试验。结果表明,室内试验中荧光假单胞杆菌PF7-5代谢产物对烟草角斑病的抑菌效果达到71%,大田试验中PF7-5活菌的50倍稀释液田间防治效果达87.34%,说明荧光假单胞杆菌PF7-5对烟草角斑病有一定的防治效果。In order to validate the biological control effect of Pseudomonas fluorescens PF7-5 against Pseudomonas syringae pv.tabacil,test was designed in archery and field.The results show that Pseudomonas fluorescens PF7-5 metabolites inhibitory effects of Pseudomonas syringae pv.tabaci to 71% in indoor test,Pseudomonas fluorescens PF7-5 to 50 times dilution of field control effect 87.34%,This experiment shows Pseudomonas fluorescens PF7-5 have a certain control effect against Pseudomonas syringae pv.tabaci.
