An adjuvant used to strengthen the spreading power of pesticide sprays. Examples include synthetic surfactants, casein lime, agricultural soap, and rosin spreading agents, with surfactants being the most widely used today. Casein lime is a powder made by adding slaked lime to milk casein, and has excellent dispersion stability and adhesion. Among surfactants, anionic surfactants (also called negative ionic surfactants) include soapless soap, sulfated oil, higher alcohol sulfate esters, and sulfonates, while nonionic surfactants are mainly composed of polyoxyethylene alkyl allyl ether, and most of the spreading agents currently on the market belong to this category. Surfactants have excellent performance in terms of dispersion stability, wetting and spreading ability, adhesion, adhesion, stability against the main agent, and resistance to hard water.

農薬の散布液の展着力を強めるために配合する補助剤。合成界面活性剤,カゼイン石灰,農業用石鹸,松脂展着剤などがあり,現在では界面活性剤が最も広く使われている。カゼイン石灰は牛乳カゼインに消石灰を加えた粉末で,分散安定性と固着性にすぐれている。界面活性剤のうちアニオン界面活性剤 (陰イオン界面活性剤ともいう) にはソープレスソープ,硫酸化油,高級アルコール硫酸化エステル,スルホン化物などが含まれ,非イオン界面活性剤はポリオキシエチレンアルキルアリルエーテルを主成分とし,現在市販されている展着剤のほとんどはこれに属する。界面活性剤は分散安定性,湿展性,付着性,固着性,主剤に対する安定性,耐硬水性においてすぐれた性能をもっている。
