摘要
通过对氟磺胺草醚可分散油悬浮剂配方的筛选实验,考察了各种助剂在配方中的作用及其对制剂性能的影响,实验结果表明,优惠配方为:氟磺胺草醚25%,乳化剂500#用量为7%,乳化剂HS-02N用量为8%,增稠剂有机膨润土为1.2%,增稠剂气相白炭黑为3%,分散剂7810为1.5%,大豆油为20%,油酸甲酯为34.3%。田间试验结果表明:25%氟磺胺草醚可分散油悬浮剂株防效和鲜重防效均优于同等剂量的25%氟磺胺草醚水剂。
he roles of various adjuvants and their influences on formulation properties of 25% fomesafen dispersed oil flowable concentrate were investigated through formula screening of fomesafen dispersed oil flowable concentrate. The optimum formulation was as follows： the amount of fomesafen 25%, the amount of emulsified agents 500# 7%, the amount of emulsified agents HS-02N 8%, the thickening agent organic bentonite 1.2%, the thickening agent fumed silica 3%, dispersant 7810 1.5%, soybean oil 20%, and methyl oleate 34.3%. Field test results showed that weed plant control efficacy and fresh weight control efficacy of 25% fomesafen dispersed oil flowable concentrate were better than that of 25% fomesafen SL at the equal application rate.
