GRANULAR AGRICHEMICAL HAVING IMPROVED DISINTEGRATING ACTIVITY AND STABILITY AND PREPARATION METHOD THEREOF

摘要

PURPOSE: The granular agrichemical having improved disintegrating activity and stability and a preparation method thereof are provided. The granular agrichemical is rapidly disintegrated and spread when applied to a paddy field. Therefore, the agrichemically active ingredients of the granular agrichemical can be effectively dispersed. CONSTITUTION: The granular agrichemical having improved disintegrating activity and stability comprises agrichemically active ingredients containing imazosulfuron, mefenacet and dymron, an extending agent, polyacrylate salt and dialkylsulfosuccinate salt, wherein the amount of polyacrylate salt is contained in the amount of 0.1 to 10 wt.%; and the amount of dialkylsulfosuccinate salt is contained in the amount of 0.1 to 5 wt.%. The method for preparing the granular agrichemical having improved disintegrating activity and stability comprises adding polyacrylate salt and dialkylsulfosuccinate salt into a system comprising an agrichemically active ingredient and an extending agent, wherein the granular agrichemical further contains a surfactant and a binder.
