摘　　要：盈江县是云南省重要的马铃薯冬作区,马铃薯晚疫病成为产业提质增效过程中的一大阻碍。生态环境保护压力不断加大,对科学用药提出更为严格的要求。为科学指导盈江县马铃薯晚疫病防控,采用小区试验,以清水为对照,比较6种杀菌剂对马铃薯晚疫病的防治效果。结果表明,处理组病斑面积百分比图曲线下平均面积极显著小于但小区平均产量却极显著高于对照。其中,500 g/L氟啶胺悬浮剂、60%霜脲·嘧菌酯水分散粒剂和10%氟噻唑吡乙酮可分散油悬浮剂处理组的病斑面积百分比图曲线下平均面积均为12.50,小区平均产量121.60~126.33 kg/22.5 m^(2),大薯率71.57~75.01%,折合产量3605~3745 kg/667m^(2),较对照增产595~735 kg/667m^(2)。选用的6种杀菌剂均对马铃薯晚疫病有良好的防治效果,其中,500 g/L氟啶胺悬浮剂、60%霜脲·嘧菌酯水分散粒剂和10%氟噻唑吡乙酮可分散油悬浮剂防治效果较好,在盈江县马铃薯种植区可以交替使用这3种药剂来防治晚疫病。Yingjiang County is an important winter potato cropping area in Yunnan Province.Potato late blight is one of the main diseases,which has become a major obstacle in the process of improving potato industry quality and efficiency.As the pressure of ecological environment protection is increasing,more strict requirements are put forward for scientific fungicide application.To scientifically guide the prevention and control of potato late blight in Yingjiang County,plot experiments were carried out to compare the control effect of six fungicides on potato late blight using water as a control.For treatments,the average areas under the curves were highly significantly less than but the average yields were highly significantly higher than that of the control.In the fungicides tested,the area under the disease progress curve of 500 g/L Fluazinam SC,60%Cymoxanil·Azoxystrobin WG and 10%Oxathiapiprolin OD was all 12.50.For these three fungicides,large-sized tuber percentage was 71.57%-75.01%,and plot yield was 121.60-126.33 kg/22.5 m^(2),equivalent to 3605-3745 kg/667m(2),increased by 595-735 kg/667m(2)compared with control.All the six fungicides tested have good control effect on potato late blight,among which,500 g/L Fluazinam SC,60%Cymoxanil·Azoxystrobin WG and 10%Oxathiapiprolin OD show better control effect.These three fungicides could be used alternately to control potato late blight in the potato planting area of Yingjiang County.
