近期,福建农林大学生物农药与化学生物学教育部重点实验室成功制备2.5%毒死蜱微球悬浮剂。研究人员首先采用流点法,对毒死蜱微球悬浮剂的润湿分散剂种类进行了筛选,在所筛选的10种分散剂中,SOPA和N-甲基脂肪酰基牛磺酸盐的流点值较小,分别为0.5032和0.4656。进一步筛选了增稠剂和防冻剂,较优配方为:11.2%毒死蜱聚乳酸微球、2.5%SOPA,2.5%N-甲基脂肪酰基牛磺酸盐、3.5%硅酸镁铝、5%乙二醇、0.15%有机 Recently, the Key Laboratory of Biopesticide and Chemical Biology, Ministry of Education, Fujian Agriculture and Forestry University successfully prepared 2.5% chlorpyrifos microsphere suspending agent. The researchers first using flow point method, chlorpyrifos microsphere suspending agent wetting and dispersing agent were screened in the selected 10 kinds of dispersant, SOPA and N-methyl fatty acyl taurate flow point value Smaller, respectively 0.5032 and 0.4656. Thickeners and antifreeze were further screened. The optimal formulation was: 11.2% chlorpyrifos PLA beads, 2.5% SOPA, 2.5% N-methyl fatty acyl taurate, 3.5% Diol, 0.15% organic
