[目的]筛选出百合根部害虫根螨、根蛆、根腐线虫的有效防治药剂。[方法]通过药效筛选试验研究20种药剂对百合根部害虫根螨、根蛆、根腐线虫的防治效果。[结果]40%道康·三唑磷乳油1 500倍稀释液+3%猎线·阿维菌素水乳剂1 500倍稀释液+50%甲基嘧啶磷800倍稀释液、2.5%黑卡·联苯菊酯乳油1 500倍稀释液+40%道康·三唑磷乳油1 500倍稀释液+3%猎线·阿维菌素水乳剂1 500倍稀释液、40%道康·三唑磷乳油1 500倍稀释液+50%甲基嘧啶磷800倍稀释液+50%敌百·辛硫磷1 500倍稀释液3个复配剂组合对百合根部害虫根螨、根蛆、根腐线虫的平均防效较好,分别为98.7%、98.3%和97.8%。[结论]40%道康·三唑磷乳油1 500倍稀释液+3%猎线·阿维菌素水乳剂1 500倍稀释液+50%甲基嘧啶磷800倍稀释液、2.5%黑卡·联苯菊酯乳油1 500倍稀释液+40%道康·三唑磷乳油1 500倍稀释液+3%猎线·阿维菌素水乳剂1 500倍稀释液、40%道康·三唑磷乳油1 500倍稀释液+50%甲基嘧啶磷800倍稀释液+50%敌百·辛硫磷1 500倍稀释液3个复配剂组合均可作为百合种球采收包装前的消毒药剂。
[Objective] The aim was to screen out effective fungicides for mite,maggot,rot nematode in roots of lily. [Method] Through pharmacodynamic screening test,the control effects of 20 fungicides on mite,maggot,rot nematode in roots of lily were studied. [Result]The average control effects of 3 compound fungicides（ 1500 times diluent of 40% daokang·triazophos EC ＋ 1 500 times diluent of 3% liexian·avermectin EW ＋ 800 times diluent of 50% methyl pyrimithate,1 500 times diluent of 2. 5% heika·bifenthrin EC ＋ 1 500 times diluent of40% daokang·triazole phosphorus EC ＋ 1 500 times diluent of 3% liexian·avermectin EW,1 500 times diluent of 40% daokang·triazole phosphorus EC ＋ 800 times diluent of 50% methyl pyrimithate ＋ 1 500 times diluent of 50% dibai·phoxime） on mite,maggot,rot nematode in roots of lily were 98. 7%,98. 3%,97. 8% respectively. [Conclusion] Three compound fungicides（ 1500 times diluent of 40% daokang·triazophos EC ＋ 1 500 times diluent of 3% liexian·avermectin EW ＋ 800 times diluent of 50% methyl pyrimithate,1 500 times diluent of2. 5% heika·bifenthrin EC ＋ 1 500 times diluent of 40% daokang·triazole phosphorus EC ＋ 1 500 times diluent of 3% liexian avermectin EW,1 500 times diluent of 40% daokang triazole phosphorus EC ＋ 800 times diluent of 50% methyl pyrimithate ＋ 1 500 times diluent of 50%dibai·phoxime） all can be used as disinfectant for Lily bulb before packaging.
