采用优化组合法选择了几种阴离子和非离子表面活性剂的复配体系及其他助剂,对15%毒死蜱.吡虫啉悬浮剂的配方进行了研究。简述了该剂型的特点、配方选择、贮存稳定性等试验结果。确定了较佳配方组成:毒死蜱5.0%,吡虫啉10.0%,分散剂MF 2.0%,分散剂NNO 0.5%,HY-11.5%,农乳500#1.0%,黄原胶0.15%,硅酸镁铝1.5%,丙二醇4.0%,正辛醇0.5%,水73.85%,配制方法及其质量控制指标。试验结果表明该配方具有成本低、工艺简单、经济效益显著等特点。
The compounding system of anionic and nonionic surfactants and other auxiliaries were selected by the optimized combination method, and the formulation of 15% chlorpyrifos and imidacloprid suspension was studied. The characteristics of the formulation, formulation selection, storage stability and other test results are briefly described. The optimum formulation was determined as follows: chlorpyrifos 5.0%, imidacloprid 10.0%, dispersant MF 2.0%, dispersant NNO 0.5%, HY-11.5%, agronomy 500 # 1.0%, xanthan gum 0.15% %, Propylene glycol 4.0%, n-octanol 0.5%, water 73.85%, preparation methods and quality control indicators. The test results show that the formula has the characteristics of low cost, simple process and significant economic benefits.
