不同植物源农药对烟青虫和斜纹夜蛾防治效果研究
Study on the Control Efficiency of D ifferent Botanical Pesticides on Heficoverpa assulta and Spodoptera litura of Tobacco
摘要
Abstract
Field experiments(in Hengyang,Hengnan and Leiyang)were conducted to study the efficiency of botanical pesti-cides (4% of rotenone and 0. 3% matrine)on controlling Heficoverpa assulta and Spodoptera litura. The result indicated that,the control effect of botanical pesticides was better than chemical pesticides,and rotenone is better than matrine,but the difference was not significant. The damage rate of tobacco plant was reduced when botanical pesticides sprayed,and the insect natural enemy was protected effectively. Rotenone and matrine controlled the Spodoptera litura and Heficoverpa assul-ta effectively,but there is no residue,safe to people and no pollution to environment. It is a direction of pesticide develop-ment in the future.关键词
