This invention provides a steamed type fumigation formulation without a smoke agent, mainly comprising an insecticide/bactericide contained pharmaceutical agent, a heat conducting agent and a natural seed. A chemical reaction heat, which is produced by adding water and calcium oxide in a wet type exothermal reactor, is indirectly, thermally conducted by a heat conducting agent with high thermal conductivity coefficient, so that active chemicals contained in the pharmaceutical agent can be rapidly gasified and volatized into the air. Accordingly, the conventional process for miniaturizing pharmaceutical agent ingredients, which generally must be performed by melting from the solid state to the liquid state, followed by gasifying from the liquid state to the gas state, can be simplified. With this invention, a smokeless fumigation effect can be provided to replace the conventional smoking processes having smoke Further, with the addition of the natural seed in the fumigation formulation of the invention, an auditory and olfactory warning unit can be provided to replace the conventional auditory warning unit that simply determines whether the medicine is applied or not by a visible smoke.本發明為一種不含發煙劑的水蒸式燻蒸製劑,主要是由一具殺蟲(菌)成分的藥劑、一熱傳導劑及一天然種子所構成,透過在濕式放熱反應裝置中添加水與氧化鈣反應產生化學反應熱,並經高導熱係數的熱傳導劑間接導熱,將藥劑中活性化學物質快速氣化揮發到空氣中,如此即可縮短傳統藥劑成分必須由「固態」融化成「液態」,再由「液態」氣化成「氣態」微小粒子的過程。本發明可將傳統有煙霧的「煙燻」作用轉變成不會產生濃煙的「燻蒸」作用,且添加天然種子可將一般傳統僅靠看到濃煙作為施藥與否判定的「視覺」警示單元轉變為「聽覺」與「嗅覺」的警示單元。10‧‧‧藥粒容器11‧‧‧外容器111‧‧‧第一空間12‧‧‧內容器121‧‧‧第二空間122‧‧‧第三空間13‧‧‧透水材料層20‧‧‧儲水21‧‧‧燻蒸藥劑22‧‧‧發熱劑23‧‧‧升溫劑24‧‧‧警示劑25‧‧‧特定植物種子26‧‧‧添加劑
