摘　　要：[目的]明确69%代森锰锌·精苯霜灵水分散粒剂对马铃薯晚疫病的防治效果,为生产上应用提供理论依据。[方法]依照杀菌剂田间药效试验准则进行田间药效试验。[结果] 69%代森锰锌·精苯霜灵水分散粒剂1552.5、1725 g a.i./hm^2处理对马铃薯晚疫病的防治效果都在86%以上,显著高于对照药剂,增产率分别为13.95%和18.43%。[结论] 69%代森锰锌·精苯霜灵水分散粒剂对马铃薯晚疫病有较好的防治效果,建议使用剂量为1552.5～1725g a.i./hm^2。[Aims] This study aims to clarify the control effect of mancozeb·benalaxyl-M 69% WG against potato late blight diseases, and provide the basis for security application in field. [Methods] According to guidelines for the field efficacy trials. [Results] The results showed that the control efficacy of mancozeb·benalaxyl-M 69% WG(1552.5 and1725 g a.i./ha) against potato late blight disease was over 86%, which was significantly higher than controls.Mancozeb·benalaxyl-M 69% WG(1552.5 and 1725 g a.i./ha) respectively gave 13.95 and 18.43% yield increase of potato. [Conclusions] Potato late blight disease could be effectively controlled by mancozeb·benalaxyl-M 69% WG.The recommended dose was 1552.5-1725 g a.i./ha in field.
