摘　　要：[方法]采用含毒介质法明确了19种杀菌剂对桃褐腐病菌丝生长的影响及对桃褐腐病的离体抑菌活性。[结果]质量浓度10 mg/L时,啶菌噁唑、腈苯唑、戊唑醇和多菌灵对桃褐腐病菌丝生长抑菌率达100%;1 mg/L时,以上4种药剂对菌丝生长抑菌率达98%以上。[结论]啶菌噁唑、腈苯唑、戊唑醇、多菌灵和氟啶胺的离体抑菌活性高于其他药剂,0.1 mg/L质量浓度下,啶菌噁唑和腈苯唑的抑菌活性较为突出,明显高于戊唑醇和多菌灵。[Methods] The effect on mycelial growth and antibacterial activity of 19 fungicides on peach brown rot in vitro were tested by a medium of containing a poison. [Results] The results showed that the inhibitory ratio of mycelial growth of SYP-Z048, fenbuconazole, tebuconazole and carbendazim was 100% at 10 mg/L, and over 98% at 1 mg/L. [Conclusions] The antibacterial activity in vitro of four fungicides were all higher than others, SYP-Z048 and fenbuconazole had more significant activity at the low concentration of 0.1 mg/L, much higher than tebuconazole and carbendazim.
