25%苯氧威水分散粒剂的研制及应用

在25％苯氧威水分散粒剂的研究中，我们进行了载体、溶剂、润湿剂、分散剂、崩解剂和乳化剂等的研究，并就不同的加工工艺对产品性能的影响进行了深入研究。筛选出最佳配方：苯氧威25％，乳酸丁酯12％，聚氧乙烯聚氧丙烯嵌段共聚物2．7％，无水十二烷基苯磺酸钙(500^#)2．3％，N-甲基-脂肪酰基-牛磺酸盐3．2％，2-乙基己基丁二酸酯磺酸盐1．9％，淀粉乙醇酸钠和碳酸氢钠3．4％，白碳黑约47．2％；选择的加工工艺可行、经济，制剂的性能优良；田间试验结果表明，与乳油的防效相当。

Fenoxycarb 25% Water Dispersible Granule

In formulating a fenoxycarb 25% water dispersible granule, research was conducted on the carrier, solvent,wetting agent, dispersing agent, disintegration agent, and emulsifier. In addition, detailed research was conducted on theeffect of different formulation methods on product properties. An optimized preparation mixture was as follows: 25?noxycarb, 12% lactate butyl ester, 2.7% polyoxyethylene polyoxypropylene block copolymer, 2.3% pesticideemulsifier #500, 3.2% dispersing agent, 1.9% wetting agent, 3.4% disintegration agent, and 47.2% micro silica powder.The selected formulating process was economical and produced a formulation with excellent properties. In field trials,the fenoxycarb 25% water dispersible granule showed efficacy equal that of the emulsifiable concentrate.
