Abstract
This paper presents the development of a suspo-emulsion(SE)formulation product containing 76% acetochlor,atrazine and 2,4-D-isoctyl(D).The optimal formulation was obtained through experiment with various components,including dispersing agents,emulsifiers,structural regulator,antifreeze agents,defoamer,and preservatives.The final formulation consists of acetochlor(32.2% ),atrazine(32.2),% and 2,4-D-isoctyl(D)(11.6% ),500#(2.6% ),1602(2.4% ),dispersant B(1.5% ),Xanthan gum(0.02% ),Magnesium Aluminum Silicate(0.5% ),SAG1572(0.15% ),kathon(0.5% ),and water to make up 100% .The test results showed that the decomposition rate of active ingredients under accelerated storage[(54±2)℃]was less than 2%,and that all the product other parameters met the requirements for SE formulation.
