摘　　要：为了研究生物药剂对马铃薯晚疫病的防治效果,本试验选择了6种生物药剂,在大田常规栽培模式下进行马铃薯晚疫病防治的药效比较试验。结果表明:不同处理对马铃薯晚疫病均具有防治和增产的效果。其中,0.3%的丁子香酚防治和增产效果最好,防效达82.58%,增产20.97%,净增加效益3472.30元·hm^(-2);其次是3%多抗霉素,防效达81.44%,增产20.54%,净增加效益3064.40元·hm^(-2)。In order to study the control effect of biological agents on potato late blight,six biological agents were selected to carry out a comparative test on the control effect of potato late blight under the field conventional cultivation mode.The results showed that different treatments had the effects of controlling and increasing production of potato late blight.Among them,0.3%eugenol had the best control effect and yield increase,with control effect of 82.58%,yield increase of 20.97%,and net increase benefit was 3472.30 yuan·hm^(-2);Followed by 3%polyantimycin,the control effect was 81.44%,the yield increased by 20.54%,and the net benefit increased by 3064.40 yuan·hm^(-2).
