Abstract

The present invention relates to a chromafenozide water emulsion and a preparation method thereof. The chromafenozide water emulsion includes the components by weight: 1-25% of chromafenozide, 3-25% of a solvent, 4-15% of an emulsifier, 1-5% of a stabilizer, 0.5-2% of a dispersing agent, 1-5% of an antifreezing agent, and the balance deionized water. The preparation method includes: dissolving the chromafenozide in a solvent to obtain an oil phase, mixing the remaining components with water to obtain an aqueous phase, and processing the oil phase and the aqueous phase under high shear conditions to obtain a finished product. The present invention provides an environmental-friendly formulation, which is simple in preparation process, low in cost, and easy for industrial production, and has broad production and application prospects.

Description

technical field [0001] The invention relates to a pesticide preparation and a preparation method thereof, in particular to a water-emulsion of chlorfenozide and a preparation method thereof. Background technique [0002] Cyclofenozide, molecular formula C 34 h 30 N 2 o 3 , chemical name: 2'-tert-butyl-5-methyl-2'-(3,5-dimethylbenzoyl) chroman-6-carbohydrazide, mainly used in vegetables, tea, fruit trees, rice fields , other crops and ornamental plants, it is not only safe for the above-mentioned plants, has no phytotoxicity, but also has no adverse effects on the environment and ecology, and is an ideal medicament in the integrated pest management system. [0003] Modern pesticide dosage forms are developing towards water-based, ultra-micronized, powder-free and controlled release, that is, water-based pesticide dosage forms. Among them, water emulsion is a kind of organic solvent that can be used less or even no, and has good efficacy and environmental protection. It i...
