目的 探讨氯硝柳胺和氯辛硫磷复方乳剂的研制及杀螺效果。方法 对常用的乳化剂进行筛选 ,筛选出最佳乳化剂 ,然后利用该两药均溶于植物油这个特性 ,制成单乳处方和复乳处方进行杀螺试验。结果 制成的乳剂稳定性好 ,能提高氯硝柳胺的杀螺效果 ,保持氯辛硫磷的增效作用。结论 氯硝柳胺和氯辛硫磷复方乳剂可以减少氯硝柳胺的用量 ,不仅降低了成本 。

Objective Study on the preparati on of the compound emulsion of niclosamide and chlorphoxim and its molluscicidal effect. Methods The best emulsifier f rom the common emulsifiers was chosen. The emulsions of niclosamide or chlorpho xim and their compound emulsion were prepared using the property of the tw o drugs that they al l can dissolve in vegetable oil, and their molluscicdal effect were tested. Results The preparation were stable and niclosamide emulsion had an increased mollu scicidal effect and c hlorphoxim emulsion increased molluscicidal effect. Conclusions The compound emulsion of niclosamide and chlorphoxim can decre a se the dosage of niclosamide, and reduce the cost and the toxicity to fish also.
