This invention, (1) the inactive carrier and the interfacial active agent and prescribing the pest shooting destruction characteristic active ingredient together, makes the granule or the powder, with the water covers the said granule or the powder with the emulsification characteristic thermoplastic polymer and becomes, the solid pest shooting destruction medicine which controlled release characteristic covered and, (2) the aforementioned pest shooting destruction medicine (1) the inactive carrier and the interfacial active agent and prescribing the same active ingredient as the active ingredient together, it makes the granule or the powder, with the water covers the said granule or the powder with the emulsification characteristic thermoplastic polymer and becomes, the solid pest which fast releasing characteristic coveredContaining with the shooting destruction medicine, controlled release characteristic and fast releasing characteristic, only by adjusting the content of the aforementioned active ingredient only by adjusting the content of the aforementioned thermoplastic polymer feature that it is allowed or by adjusting with the content of the aforementioned thermoplastic polymer and the content of the aforementioned active ingredient in the pest shooting destruction medicine composition which becomes, the pest shooting destruction medicine composition is stated. This composition changes makes the emission characteristic of desire possible under the temperature condition especially for rising.本発明は、(1)有害生物殺滅性の有効成分を不活性担体及び表面活性剤と一緒に処方して顆粒又は粉末とし、該顆粒又は粉末を水で乳化性の熱可塑性ポリマーで被覆してなる、徐放性の被覆した固体有害生物殺滅剤と、(2)前記有害生物殺滅剤(1)の有効成分と同じ有効成分を不活性担体及び表面活性剤と一緒に処方して顆粒又は粉末とし、該顆粒又は粉末を水で乳化性の熱可塑性ポリマーで被覆してなる、速放性の被覆した固体有害生物殺滅剤とを含有してなる有害生物殺滅剤組成物において、徐放性及び速放性は前記熱可塑性ポリマーの含量を調節することによってのみ、前記有効成分の含量を調節することによってのみあるいは前記熱可塑性ポリマーの含量と前記有効成分の含量とを調節することにより加減されることを特徴とする、有害生物殺滅剤組成物を記載する。この組成物は、変化する特に上昇する温度条件下で所望の放出特性を可能とする。
