【摘要】 通过室内浸叶法和田间药效实验,分别测定了亲态保混剂1号和2号对斜纹夜蛾、二化螟、小菜蛾、三化螟、稻纵卷叶螟等重要鳞翅目害虫的杀虫活性。室内测定共毒系数的结果表明,亲态保1号比单一制剂对斜纹夜蛾、二化螟、小菜蛾有明显的增效作用;田间药效试验结果表明,亲态保防效均高于单一制剂,其中亲态保2号和1号每亩160g剂量对3代三化螟和稻纵卷叶螟的防治效果分别为88.1%和87.1%,防效均在85%以上,高于单一制剂的药效,有较好的推广应用价值。更多还原

【Abstract】 The synergistic activity of the mixture of BT and triazophos was evaluated by using the method of CTC. The test indicated that the mixtures (1:1) had higher synergistic activities than the mixture (1:2) on Plutella xylostella, Prodenia litura , Chilo suppressalis (Walker). The Control efficacy of mixture 1 and 2 were 88.1% and 87.1% respectively, which were higher than the control of BT and triazophos on Plutella xylostella, Prodenia litura, Chilo suppressalis (Walker).更多还原
