Abstract

PURPOSE:To obtain a granule coated with an agricultural chemical active ingredient, by dissolving an isocyanate compound and water-soluble high polymer which is a solid at ordinary temperature in water and bringing the resultant solution into contact with a granular carrier, adding and mixing the agricultural chemical ingredient to form a film on the surface of the granular carrier. CONSTITUTION:Water and a solid water-soluble high polymer (e.g. polyvinyl alcohol) having >=10,000 average mol.wt. are previously placed in a container and a granular carrier (e.g. silica sand or CaCO3) is then added and mixed. An isocyanate compound is further added to form a film from the formed polyurethane and water-soluble high polymer. An agricultural chemical active ingredient is directly or adsorbed on an oil absorbing fine powder and then added and mixed therewith to afford the aimed granule containing the carrier homogeneously coated with the composite film in a state of the active ingredient homogeneously dispersed therein. Since there is no heating step, this method can be applied even to an active ingredient unstable to heat. Since the active ingredient is firmly and homogeneously adhered, peeling and scattering will not occur in storing and transporting and danger and injury to operators and environmental pollution are prevented.
