TaskWater environmentBy dropping it on the surface of the water, self diffusion in the entire water surface in a short timeToMedicineHow to spray, Jumbo agent and water surface spreading agentUse ofSaving labor for drug spraying work on the water environment and spreading evenlyHow labor-saving chemicals can be sprayedI will provide a.SOLUTION:Chemical ingredients, Which dissolves or adsorbs in the chemical component or covers the chemical component,The chemical component is supported on the water surface without sedimentation,A flowable mixture comprising a liquid diffusion action component for diffusing the chemical component on the water surfaceA self-water surface diffusion type labor saving agentFirst, it poured into the water surface of the water environment, diffused horizontally on the surface of the water, and subsequently reach the bottom of the water environment later than the diffusion distribution of the self-water surface diffusion type labor-saving agent in the horizontal direction To gradually dissolve from the water surface in water vertically in order to diffuse the chemical component into the water environment by a sequential two-stage diffusion mechanismCharacterized byLabor-saving agent spraying methodRespectively.BACKGROUND OF THE INVENTION【課題】水環境の水面に滴下することで、水面全面に短時間で自己拡散させる薬剤の散布方法であって、ジャンボ剤及び水面展開剤の使用よりもさらに水環境への薬剤散布作業の省力化、均一拡散化を図ることができる省力化薬剤散布方法を提供する。【解決手段】薬品成分と、前記薬品成分に溶解又は吸着し、或いは前記薬品成分を被覆し、前記薬品成分を沈降させることなく水面上に支持し、前記水面で前記薬品成分を拡散させる液状の拡散作用成分を含んでなる流動性の混合物である自己水面拡散型省力化薬剤を先ず、水環境の水面に注ぎ入れ、水面で水平方向に拡散分布させ、続いて、前記自己水面拡散型省力化薬剤を、前記水平方向に拡散分布するよりも遅れて前記水環境の底部に到達する前記水面から水中へ鉛直方向に緩やかに溶解させる、逐次的二段階拡散機構によって前記薬品成分を前記水環境に拡散させることを特徴とする省力化薬剤散布方法とした。【選択図】図1
