２．５％溴氰菊酯缓释型微乳剂防制卫生害虫的研究

目的：以水替代有机溶剂减少环境污染，以高分子材料作为缓解剂控制药物释放速度。方法：参照农药登记室内药效实验有关方法等。结果：该剂对蚊、蝇击倒迅速、杀灭力强，与２．５％敌杀死ＥＣ相当；作为滞留喷洒其持效性长，与２．５％凯素灵相近，毒性低、热贮稳定性好，并在一定温度范围内保持特理稳定性。结论：该剂是良好的喷射剂。

Study on the Pest Control with 2.5% Control Release Micro-emulsion of Deltamethrin

Objective:To reduce the use of organic solvent and to control the release of efficiency. Methods:Refer to efficacy test concerned methods of public health insecticides for registration,on the basis of taking high-molecular compound as control release formutation and substituting organic solvent for distilled water, 2.5 % Control release micro-emulsion of Deltamethrin has been developed. Result:The insecticide knocked mosquito and fly down quickly,and killed them powerfully well-matched as 2.5 % Decis;which used as delaying spray has efficiency as long as 2.5 % K-othrine nearly. Conclusion:It's low toxicity company good stability either chemical or physical.It can be taken as an effective spray.
