[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. |
