摘　　要：为了筛选对腐烂茎线虫有良好防治效果且适宜生产应用的药剂,采用蘸根法分别测试了6种药剂对甘薯腐烂茎线虫病防治效果,并对其经济效益进行分析。试验结果表明,药剂蘸根处理后,薯苗成活率都在95%以上,长势健壮。5%阿维菌素微囊悬浮剂、30%辛硫磷微囊悬浮剂和21%阿维·噻唑膦水乳剂对腐烂茎线虫病的防治效果都在80%以上,其中,30%辛硫磷微囊悬浮剂防治效果最高为91.5%。各处理均可显著降低病株率、病薯率,提高健薯产量,667 m2增收107.50~855.00元。综合考虑防治效果、用药成本和投入产出比,30%辛硫磷微囊悬浮剂防治甘薯茎线虫病较为经济有效,可在适宜地区考虑推广应用。In order to screen the nematocides with excellent efficacy against Ditylenchus destructor and suitable for application,the efficacies and economic benefits of 6 kinds of nematocide on Ditylenchus destructor were evaluated by root-dipping method in three different counties of Henan Province.The results showed that the sweet potato seedlings grew vigorously and the survival rates of each treatment were more than 95%.The efficacies of abamectin 5%CS,phoxim 30%CS and abamectin·fosthiazate 21%EW on Ditylenchus destructor were more than 80%,and the control effect of phoxim 30%CS was the best.All nematocides could reduce the rates of diseased plant and potato,increase the yield of healthy potatoes,with an averaged income of 107.50-855.00 yuan per 667 m2.Phoxim 30%CS was the most economical and effective nematicide against Ditylenchus destructor on sweet potato and could be promoted and applied in suitable areas.
