5种药剂对川麦冬根结线虫的防治效果

Control Effect of Five Nematicides against Ophiopogonis radix Root-kont Nematode Disease

[目的]防治麦冬根结线虫病,对5种杀线虫药剂进行田间防效评价试验。[方法]2019年在四川省绵阳市三台县永明镇麦冬种植基地进行了5种不同杀线虫药剂对麦冬根结线虫防治的田间试验,通过防效时长、J2线虫防治效果对供试药剂进行评价。[结果]处理③噻唑磷防效最高,为86.11%,处理①淡紫拟青霉防效最低,仅为30.56%,其余处理防效均在80.00%以上。[结论]5种供试药剂均对麦冬根结线虫有一定防效,建议在生产上优先推广应用10%噻唑磷颗粒剂,同时可以采用药剂复配,减药增效,进一步提高中药材种植用药安全。

[Objective]To control root knot nematode disease of Ophiopodiae Radix,five nematode killing agents were evaluated in field.[Method]In 2019,a field experiment was conducted on the control of five different nematode killing agents against root nematodes in the planting base of Ophiopodiae Radix in Yongming Town,Santai County,Mianyang City,Sichuan Province,and duration of control effect,J2 nematode control effect were evaluated.[Result]③treatment was the highest(86.11%),the control effect of①was the lowest(30.56%),and the control effect of other treatments were more than 80.00%.[Conclusion]All the five nematode killing agents tested had certain control effect on Ophiopogonis radix.It was suggested that fosthiazatem10%GR should be given priority in the production.Meanwhile,different nematode killing agents could be used in combination to reduce the use of pesticides and improve the effect,which would further improve the safety of planting and administering Chinese medicinal materials.
