Document Type and Number:
Japanese Patent JP5073516
Kind Code:
B2
Abstract:
This invention provides a method for manufacturing pesticide granules, which includes: blending water with a mixture of pesticide active components, plastic hollow micro bodies, surfactant, adhesive and calcium carbonate (CaCO3); proceeding an extrusion-granulation process to make granules; and drying the granules. Furthermore, the content of water in the composition after blending is 15-25 wt%, and the content of CaCO3 in the mixture before blending with water is 30-90 wt%. The quantity of CaCO3 takes up a proportion of 15-30 parts by weight with respect to 1 part by weight of the plastic hollow micro-cells. The pesticide granules obtained by the manufacture method of this invention have excellent floatability on the water, the diffusion property and so on to be suitable for a use in rice field. This manufacture method can be used in the industry to efficiently make pesticide granules.
