Method of producing granular preparation of agricultural cehmical for rice paddy
专利汇可以提供Method of producing granular preparation of agricultural cehmical for rice paddy专利检索，专利查询，专利分析的服务。并且PURPOSE: When title preparation is produced by impregnation of bentonite-crushed particles, the impregnation is effected in the coexistenece of a specific higher fatty acid, fluid paraffin or surfactant, thus controlling the initial elution of the ingredients of agricultural chemicals.
CONSTITUTION: Crushed particles of bentonite is impregnated with liquid ingredients of agricultural chemicals at room temperature or with a solution of the solid ingredients in nonvolatile solvents at room temperature to prepare granular preparation of agricultural chemicals for rice paddy without passing throgh drying step wherein a liquid fatty acid at room temperature such as oleic acid or vegetable oil and fluid paraffin or surfactant such as sodium alkylbenzenesulfonate or sodium dinaphthylsulfosuccinate are added to the impregnant. The paraffin increases the initial elution of the effective components to develop the early effect, whereas the surfactant depresses the elution of high extractive components to delay the development of the effect.
