| 摘 要： | [目的]筛选出对桑园害虫防治效果好,桑叶残毒对家蚕影响小的杀虫剂。[方法]采用室内毒力测定、田间药效试验、农药残留速测以及残毒测定相结合的方法进行试验。[结果]室内毒力测定结果表明,桑树1号对桃粉绿芽的LC50为（316.1±57.3）mg/kg,桑树1号在药后14d,防效达62.58%;药后7d的农药残留速测显示可安全饲育家蚕,达到用叶标准。[结论]推荐桑树1号作为桑园专用杀虫剂使用。

| Abstract: | [Objective]The paper was to screen the pesticides with good control effects against pests in mulberry and small impact on silkworm.[Method]The combined method of indoor toxicity test,field efficacy test,fast testing of pesticide residues and residual toxicity determination were adopted to carry out test.[Result]Indoor toxicity results showed that LC50 of Mulberry No.1 against Hyalopterus amygdale was(316.1 ±57.3) mg/kg,and the control effect of Mulberry No.1 at 14 d reached 62.58%;fast testing of pesticide residues at 7 d showed that the mulberry leaves were safe to silkworms,which reached the standard of leaves for silkworm.[Conclusion]Mulberry No.1 was recommended to be the special pesticide to apply in mulberry field. |
