Organic bentonite pesticide sustained-release granular formulation and preparation method thereof

InactiveCN102578081AGood compatibilityDoes not constitute pollutionBiocideFungicidesChemical structureControl release
The invention relates to a sustained-release granular formulation for preventing and treating crop diseases and insect pests and a preparation method thereof. The pesticide sustained-release granular formulation comprises bentonite, an organic modifier, pesticide active ingredients, an inert filler and a binding agent, and is prepared by the preparation method comprising the steps of: (1) with the bentonite as a basic material, modifying the bentonite by the organic modifier to obtain organic bentonite; (2) loading the pesticide active ingredients on the organic bentonite to prepare medicine-carrying organic bentonite; and (3) mixing the medicine-carrying organic bentonite, the inert filler and the binding agent proportionally, and pelleting to obtain the sustained-release granular formulation. The preparation method of the sustained-release granular formulation, provided by the invention, not only overcomes the defect of low pesticide loading rate of the natural bentonite, but also realizes the controlled release of the pesticide by adjusting a chemical structure and the amount of the modifier, so that the sustained-release granular formulation is coincident with an occurrence rule of the plant diseases and insect pests, and the pesticide sustained-release granular formulation is used safely, reasonably, economically and effectively.
