| 中文摘要: |
| 通过对香蕉枯萎病株中尖镰孢菌进行分离鉴定并培养，研究不同pH、温度和盐浓度下百菌清与多菌灵对尖镰孢菌的抑制效果。实验结果表明：百菌清和多菌灵对尖镰孢菌孢子均没有明显的抑制效果，但有明显的抑菌作用。百菌清对尖镰孢菌的最低抑菌浓度(MIC)为16.62μg/mL，而多菌灵的MIC为10.99μg/mL，后者比前者低33.90%；百菌清的抑菌效果不受温度、pH、离子强度等环境条件的影响，多菌灵则在温度升高和pH大于6.0后抑菌效果会因其稳定性降低而降低。在防治香蕉枯萎病方面，多菌灵比百菌清更为有效，但在使用时要注意避开高温和高pH环境。 |
| 英文摘要: |
| Based on the scanning, identifying and incubating of Fusarium oxysporum f. sp. Cubense, the antifungal effects of chlorothalonil and carbendazim on it were researched under different pH, temperature and salt concentration. The results of experiments showed that both chlorothalonil and carbendazim have noticeable antifungal activity to the mycelium growth but to the spore germinating. The MIC of chlorothalonil on Fusarium oxysporum f. sp. Cubensewas 16.62μg/mL. The MIC of carbendazim was 10.99μg/mL and lower 33.90% than chlorothalonil’s. The anti-fungus’ effects of chlorothalonil was not affected byTemperature, pH and ionic strength, but the effects of carbendazim was decreased with the stability declination under higher temperature and pH higher than 6.0. Using of carbendazim should avoid high temperature and high pH environment. |
