摘　　要：介绍了通过绘制烟嘧磺隆/表面活性剂/正丁醇/水拟三元体系相图,制备烟嘧磺隆水基化微乳剂的方法。从表面活性剂筛选入手,对阴离子、非离子表面活性剂复配,确定了水基化微乳液的配方,研究了水质、热贮、冷贮对制剂稳定性的影响,同时进行了流变性及高效液相测定原药含量等实验,分析原药分解率。该方法获得的烟嘧磺隆水基化微乳剂,具有成本低,质量稳定,使用环保、安全,市场前景看好等特点,社会、经济效益显著。In this paper, the composition and additives of water dispersible pesticide formulation of nieosulfuron microemulsions was introduce. By drawing the phase diagrams of the surfactants/nicosulfuron solution/water system determine the micro-emulsion composition. It studied the affect of temperature and water quality on the physical to stability of the water dispersible pesticide formulation preparation. The composition has many good characteristics, for example low cost, stable quality, safety in use, good foreground in market and notable society benefit.
