摘　　要：[目的]筛选出防治马铃薯晚疫病和早疫病的有效药剂。[方法]选取不同杀菌剂对马铃薯晚疫病和早疫病进行了田间防效研究。[结果]烯酰·吡唑酯、双炔酰菌胺和噁酮·霜脲氰对马铃薯晚疫病的田间防效最高,分别为95.89%、95.86%和95.81%;苯甲·嘧菌酯和肟菌·戊唑醇对马铃薯早疫病的田间防效最高,分别为92.66%和91.21%。[结论 ]为马铃薯晚疫病和早疫病的综合防控提供技术支持。[Objective] The aim was to screen out the effective fungicides for control of potato late blight and potato early blight. [Method] The control effects of different fungicides on potato late blight and potato early blight were studied in the field. [Result] The control effects of Dimethomorph·pyraclostrobin,Mandipropamid and Famoxadone·cymoxanil on potato late blight were the highest,95.89%,95.86% and 95.81% respectively;Difenoconazole·azoxystrobin and Trifloxystrobin·tebuconazole had the highest control effects on potato early blight,92.66% and 91.21% respectively. [Conclusion] The results provided technical support for the comprehensive control of potato late blight and potato early blight.
