Abstract

The invention relates to emamectin emamectin salt water dispersible granules and a preparation method thereof, belonging to the technical field of pesticide preparation. The above-mentioned emamectin emamectin saline dispersible granule is composed of the following components in mass percentage: 5% to 30% emamectin emamectin salt original drug, 1% to 5% anionic dispersant, 1% to 5% solid wetting agent, 5% to 20% modified cyclodextrin, and the remaining fillers make up to 100%; the modified cyclodextrin is a sulfonate, carboxylate, carbamic acid esterified with the C-2, 3, and 6 positions of the cyclodextrin one or more of esters. The water-dispersible granule of the invention has the advantages of good dispersibility, easy disintegration, stable performance and the like.

Description

technical field [0001] The invention relates to the technical field of pesticide preparation, and specifically provides emamectin emamectin salt water dispersible granules and a preparation method thereof. Background technique [0002] Water-dispersible granules are mainly composed of dispersants, wetting agents, defoamers, pH regulators, fillers, etc. The main properties are: effective content, disintegration, dispersibility, suspension rate, persistent foaming, pH value And room temperature, thermal storage stability, etc. The level of disintegration and suspension rate directly affects the efficacy of the drug, which is closely related to the properties of the active ingredients, the dispersant, wetting agent, and filler used. In the same formulation, the use of different dispersants or wetting agents will significantly affect the performance of the formulation. If the active ingredients of pesticides, dispersants, wetting agents, and fillers are not compatible, the perf...
