摘　　要：为减轻马铃薯晚疫病对马铃薯生产造成的损失,本研究选择了8种药剂,在马铃薯地上垄体栽培模式下进行晚疫病防治的药效比较试验。结果表明,不同处理均对地上垄体栽培模式下马铃薯晚疫病具有防治和保产的效果。其中,在马铃薯晚疫病发病前期喷施的保护性杀菌剂种中,60%百泰的防治和保产效果最好,防效达79%以上,增产43.54%;其次是银法利,防效达70%以上,增产42.55%。在发病中期喷施的治疗性杀菌剂中,防效和保产效果最好的药剂为50%安克,防效达73%以上,增产36.71%。In order to prevent yield loss and poor quality of potatoes on aboveground ridge body cultivation model, eight fungicides were evaluated for their late blight control efficacy. The results showed that all fungicides were effective for late blight control and yield prevention. The best control effect was 60% Pyraclostrobin ＋ Metiram WG, when used as protective fungicide at initial stage of potato late blight, with control effect being above 79% and yield increase by 43.54%. Followed was Propamocarb ＋ Fluopicolide with control effect being above 70% and yield increase by 42.55%. For therapeutic fungicides sprayed at middle stage of potato late blight, the best control effect was 50% Dimethomorph, with control effect being above 73% and yield increase by 36.71%.
