Objective: To study the antibacterial activity of crude extracts from 6 medicinal plants against 4 plant pathogenic fungi. Method: The antibacterial activities of 6 medicinal plants against Fungi Imperficti, Fusarium oxysporum, Pythium aphanidermatum and Phytoph-thora capsici were observed. The results showed that the crude extracts of Lycoris radiata, Zingiber officinale and Xanthium sibiricum had good antibacterial effects on four pathogenic fungi. Among them, Lycoris radiata and Xanthium sibiricum had obvious antibacterial activities against Fusarium oxysporum, and the antibacterial rates were 90.17% and 85.58% respectively. Zanthoxylum bungeanum can inhibit Fungi Imperficti and promote the growth of other three pathogenic fungi. Conclusion: The crude extracts of Lycoris radiata and Xanthium sibiricum have extensive antibacterial activities. The antibacterial rates of Lycoris radiata and Zingiber officinale against four plant pathogenic fungi were more than 70%, and the antibacterial rate against Fungi Imperficti was as high as 90%. The antibacterial rate of Xanthium sibiricum to Fungi Imperficti was more than 85%. Therefore, these two plants contain certain agricultural antibacterial components, which can be used as two potential plant derived pesticide development resources and have good antibacterial activity.
