松树枯梢病是松树的重要病害之一,本试验采用抑菌圈法测定了银杏枝叶提取物及4种化学杀菌剂对松树枯梢病菌的抑制作用。结果表明:可杀得对松树枯梢病菌抑制作用最强,其次为多菌灵、银杏枝提取液、银杏叶提取液。银杏枝、叶提取液对松树枯梢病菌有很高的抑菌活性,与可杀得及多菌灵对病菌的抑制作用差异不显著。而杜邦易保和瑞毒霉—锰锌抑菌效果较差,与银杏枝、叶提取液对病菌的抑制作用差异显著。

Pine blight is one of the important diseases of pine. In this experiment, the inhibitory effect of Ginkgo biloba extract and four kinds of chemical fungicides on pine blight was determined by inhibition zone method. The results showed that the killing effect on the pine blight was the strongest, followed by carbendazim, ginkgo biloba extract and ginkgo biloba extract. Ginkgo biloba, leaf extract on the pine blight bacteria have a high antibacterial activity, and can kill and carbendazim on bacteria inhibitory effect was not significant. However, the inhibitory effect of DuPont easy to protect and reesei mildew - manganese and zinc is poor, and ginkgo sticks and leaves extract on bacteria significantly different.
