摘　　要：为明确5%香芹酚水剂对马铃薯晚疫病的防效和安全性,采用田间药效试验的方法进行了5%香芹酚水剂对马铃薯晚疫病的田间药效试验。结果表明,5%香芹酚水剂对马铃薯晚疫病的防效良好,2250 mL/hm^(2)喷雾的防效达到83.13%,显著高于70%烯酰·丙森锌可湿性粉剂1500 g/hm^(2)喷雾的防效76.78%,较对照增产17.59%。In order to clarify the control effect and safety of 5% carvacrol aqueous solution on potato late blight,the field efficacy test of 5% carvacrol aqueous solution on potato late blight was carried out in the field.The results show that the 5% carvacrol aqueous solution has a good control effect on potato late blight,and the control effect of 2250mL/hm^(2) spray reaches 83.13% ,which is significantly higher than that of 70% acryloxyethyl-zinc wettable powder 1500 g/hm^(2) spray(76.78% ).The output was increased by 17.59% compared with the control.
