5％啶虫脒乳油的配方研究

目的]为了提高药效，同时减少对环境的污染，设计了5％啶虫脒乳油的不同配方。方法】通过冷贮、热贮、外观比较、酸碱度测定等方法测试了溶剂的溶解性和乳化剂的乳化效果。结果]混苯作溶剂；乳化剂3．2％103、2．7％107、1．5％农乳500比例下得到的药剂溶解性好，稳定性较强；冷贮后pH值稳定而且啶虫脒析出率为0．36％，热贮后pH值稳定，没有絮状物出现，啶虫脒分解率为1．84％。结论]5％啶虫脒乳油配方为：3％二甲基甲酰胺作助溶剂，由3．2％103、2．7％107、1．5％农乳500混合作乳化剂，混苯作溶剂补齐100％。

Research on the Formula of 5% Acetamiprid EC

Objective] The present study aims to look for the perfect formula of 5% acetamiprid EC based on the several formulas.Methods] Solubility of solvents and the emulsification of emulsifier were measured.Results] when the pesticides were dissolved with mix Benzene and were emulsified by 3.2% 103,2.7% 107 and 1.5% Nongru 500 emulsifier,the pesticides were looked very well and the pesticides also showed a higher stability.The low or high temperature had no effect on the pH value and the content of 5% acetamipr...
