PCT No. PCT/JP96/02116 Sec. 371 Date Jan. 28, 1998 Sec. 102(e) Date Jan. 28, 1998 PCT Filed Jul. 26, 1996 PCT Pub. No. WO97/04652 PCT Pub. Date Feb. 13, 1997A coated granular pesticide comprising a granular pesticide for use on plants which comprises at least one hardly water-soluble active ingredient and at least one water-swelling substance, and a thermoplastic resin-based film which covers the surface of the granular pesticide; a method for producing the same; and applications thereof. A surfactant, inorganic powder insoluble or hardly soluble in water, water-absorbing and/or water-soluble polymer fine powder, a thermosetting resin, or a biodegradable polymer insoluble or hardly soluble in water, or a combination thereof may be incorporated into the film. The coated granular pesticide can externally release the hardly water-soluble active ingredient due to the combined effects of the thermoplastic resin as the film-forming component and the water-swelling component as the core component whereby the water-swelling substance absorbs the water present in the exterior of the coated granular pesticide, which gradually penetrates into the granule through the coating film. |
