生物杀虫剂B_(9-1)是由几种植物有机体合成的,性状稳定。通过室内模拟试验及田间试验,对棉花、油菜、四季豆、菊花、枝枝花等作物蚜虫及夜蛾,叶蜂的幼虫药效可达95％以上,对小麦穗蚜、菜青虫、小菜蛾幼虫药效可达70.4％～76.7％。研究结果表明,应用生物杀虫剂同样可以防治作物害虫,并为绿色食品生产提供了重要措施。
Biopesticide B_ (9-1) is synthesized by several plant organisms and has stable characters. Through indoor simulation experiments and field experiments, the efficacy of cotton, rape, green beans, chrysanthemum, branch flowers and other crops aphids and larvae of the moth, leaf bee larva of up to 95%, spike aphids, Pieris rapae, Plutella xylostella Larvae efficacy up to 70.4% ~ 76.7%. The results show that the application of biological pesticides can also prevent crop pests and provide important measures for green food production.
