摘　　要：为了更好地防治豇豆根结线虫病,对4种杀线虫剂进行了田间防效评价试验。结果表明,供试的4种药剂均对豇豆根结线虫有一定的防效,能控制土壤中2龄幼虫的数量和抑制根结的形成,其中10%噻唑膦颗粒剂对豇豆根结线虫的防效最好,具有低残留、持效期长等优点,可作为防治豇豆根结线虫的首选药剂;其次为5%阿维菌素颗粒剂。同时供试的4种药剂在试验剂量范围内均对豇豆安全,建议在生产上推广应用10%噻唑膦颗粒剂和5%阿维菌素颗粒剂来防治豇豆根结线虫病。In order to control cowpea root-knot nematode disease,field trials were conducted to validate the efficacy of four nematicides.The results indicated that these chemicals had good efficacy on nematodes.Fosthiazate10% GR had the best effects on J2 and formation of root-knot,followed by abamectin5% GR.Meanwhile,four nematicides were safe to cowpea within the treated doses.We suggested that fosthiazate 10% GR and abamectin5% GR could be recommended for the control of root-knot nematode disease in cowpea production.
