| 摘 要： | 采用田间喷雾施药，在陕西省榆林市进行了马铃薯早疫病防治技术研究。开展不同药剂混配的防效比较试验。试验结果表明：不同处理均对早疫病有抑制作用，且存在显著差异，其中：苯酰锰锌+精甲霜锰锌、吡唑醚菌酯+枯草芽孢杆菌、代森锰锌+ 氟噻唑吡乙酮药剂组合对早疫病防效较好，防效分别为74.2%、70.3%、67.6%，兼有防控晚疫病作用，建议推广使用；丙森锌+烯酰吗啉、苯酰锰锌+精甲霜锰锌、氟啶胺+氟菌·霜霉威、嘧菌酯+噁酮·霜脲氰处理的防效较差，依次为：58.9%、54.6%、50.8%和50.5%。

| Abstract: | To effectively prevent and control potato early blight, the control technology was investigated in Yulin area, Shaanxi Province. The field spraying was used to compare the efficacy of different pesticide mixtures. The results showed that different treatments had inhibitory effects on early blight, with significant differences. Among them, the combination of benzoyl mancozeb + metalaxylmancozeb, pyraclostrobin + Bacillus subtilis, mancozeb + fluthiazolylpyrazole ethyl ketone had better control effect on early blight, which were 74.2%, 70.3% and 67.6%, respectively,and had effect on preventing and controlling late blight, which was recommended for widespread use. The control effects of propineb + dimethomorph, mancozeb + metalaxyl, fluazinam + fludioxonil · propamocarb, azoxystrobin + oxone · cymoxanil were 58.9%, 54.6%, 50.8% and 50.5 %, respectively. |
