摘　　要： [目的]研究普洱茶醇提物对几种植物病原菌抑菌活性,为普洱茶在农业病害防治方面的应用提供参考。[方法]利用菌丝生长速率抑制法研究普洱茶醇提物对几种植物病原菌的抑制作用。[结果]普洱茶醇提物对水稻纹枯病菌、西瓜枯萎病菌、棉花枯萎病菌和棉花黄萎病菌均有一定的抑制作用。其中,对水稻纹枯病菌抑制作用最好,其EC50为1435.5mg/L;对棉花枯萎病菌的抑制作用最小,其EC为3013.0mg/L。[结论]普洱茶醇取物在植物病害防治和新型杀菌剂开发方面具有潜在功能。 [Objective] The aim was to study Pu-erh tea methanol extracts on antibacterial activity of several plant pathogens and provide reference for application of Pu-erh tea in agriculture disease prevention and control. [Method]The inhibitive effect of Pu-erh tea methanol extracts on several plant pathogens was studied by adopting mycelium growth rate method. [Result] The results showed that Pu-erh tea methanol extracts had inhibitive effects on Thanatephorus cucomeris （Frank） Donk,Fusarium oxysporum f.sp.niveum,Fusarium oxysporum f.sp.Vesinfectum （Atk·） Snyder et Hawsen and Verticillium dahliae kleb. Among which,the inhibitory effect on Thanatephorus cucomeris （Frank） Donk was the best,the EC50 was 1 435.5 mg/L; the inhibitory effect on Fusarium oxysporum f·sp·Vesinfectum （Atk·） Snyder et Hawsen was the lowest,the EC50 was 3 013.0 mg/L. [Conclusion] Pu-erh tea methanol extracts have potential function in the control of plant disease and development of new fungicide.
