桓仁县杨扇舟蛾化学防治试验

杨扇舟蛾是一种对杨树危害性较强的森林害虫。在辽宁省桓仁县黑沟林场应用3.6%烟碱·苦参碱微囊悬浮剂等3种化学药剂开展了杨扇舟蛾防治试验,结果表明:3种药剂中以喷施3.6%烟碱·苦参碱微囊悬浮剂1500倍液为佳,7d后防治效果达到99%以上。3.6%烟碱·苦参碱微囊悬浮剂烟碱在自然环境里降解速度快,对大气、土壤、植物无污染,可在杨扇舟蛾防治中推广应用。

Chemical Control Experiment Against Scolophora alopecuroides

Clostera anachoreta is a forest pest which is more harmful to poplar.Experiments of controlling Populus delavayi was conducted by applying 3.6% nicotine matrine microcapsule suspension in Huanren County of Benxi City in Liaoning Province.Result shows that 1 500 times 3.6% nicotine matrine microcapsule suspending agent can obtain the optimal effect;control effect reach above 99% after 7 days;3.6% nicotine matrine microcapsule suspension nicotine degraded quickly in the natural environment,which has no pollution to atmosphere,land and plant;it is recommended to promote in controlling Scolophora alopecuroides.
