2014年在福建省沙县选取具有代表性的闽粤栲林标准样地，采用不同处理的植物源杀虫剂对其食叶害虫进行防治，其中不同浓度的1.2％烟碱·苦参碱乳油、5％桉油精可溶液剂、碧绿1％苦参碱采用喷烟技术，不同用药量的1.1％苦参碱粉剂采用喷粉技术，防治黄刺蛾、栎黄掌舟蛾、扁刺蛾、褐边绿刺蛾、毒蛾的幼虫。结果表明：用药3 d 后，4种药剂防治效果均可达90％以上，其中2种苦参碱类药剂1∶9为林间防治最佳使用浓度；5％桉油精可溶液剂林间防治最佳使用浓度为1∶50；22.5 kg／hm2为1.1％苦参碱粉剂生产中最佳林间药剂用量，供试的4种药剂均可以作为闽粤栲的无公害防治药剂。

A representative standard plot of Castanopsis fissarehd forest in Shaxian County was selected in 2014,and applied different plant source pesticides on Castanopsis fissarehd forest to test the control efficiency of leaf eating pest.Of them,application method of 1.2% nicotine,5% eucalyptol solution,1% soluble matrine was applying smoke spraying technology,and different dosage of 1.1% matrine powder was applying dusting technology to prevention of Cnidocampa flavescens,Phalera assimilis,Thosea sinensis,Latoia consocia,Porthesia similis moth larvae.The results showed that:administration for 3 d,control efficiency of 4 kinds of chemical could reach more than 90%,of which 2 kinds of matrine type with 1∶9 was the control optimal concentration.For 5% eucalyptol so-lution,control efficiency of the concentration of 1∶50 was the best.The dosage of 1.1% matrine powder production with 22.5 kg/hm2 was the optimal amount for forest.Therefore,the all tested 4 reagents could be as Castanopsis fis-sarehd pollution-free control agent.
