Abstract

The invention discloses an iprobenfos microemulsion and a manufacturing method thereof. The iprobenfos microemulsion is prepared from 5-40 percent of iprobenfos, 0-5 percent of cosolvent, 0.5-5 percent of stabilizer, 8-20 percent of surface active agent and water up to 100%. In the iprobenfos microemulsion, aromatic organic solvent in missible oil is replaced by water, thereby preventing the environment from being polluted by triphenyl organic solvent and ensuring safer production, package, transportation and use, and simple and easy production technique. The iprobenfos microemulsion has thinner liquor particles than the missible oil after being diluted, which is favorable for the absorption of crops, thereby improving the use ratio of medicaments and enhancing the prevention and treatmenteffect of medicaments.

Description

technical field [0001] The invention relates to a micro-emulsion of isidaobangjing and a manufacturing method thereof, belonging to the technical field of pesticide preparation processing. Background technique [0002] Isodobenfos, chemical name: O, O-diisopropyl-S-benzyl phosphorothioate, English common name iprobenfos, molecular formula: C 13 h 21 o 3 PS, boiling point: 126°C / 5.33Pa, melting point: 22.5-23.8°C, the original drug is light yellow oily liquid, slightly soluble in water, easily soluble in various organic solvents. It is relatively stable to light and acid, and it is easy to decompose when it encounters alkaline substances, and it will also cause decomposition when exposed to high temperature or long-term high temperature. The systemic fungicide of Isomidajing mainly hinders the synthesis of chitin by interfering with the permeability of the cell membrane, so that the bacteria cannot develop normally. It is mainly used to prevent and control rice blast. It ...
