Description

  The present invention relates to a spreading agent composition.

  Plant leaves, stems, and insect epidermis have components or structures that repel liquids. For this reason, the sprayed pesticide may not adhere to the skin surface and may not exhibit a sufficient effect.

  Therefore, by mixing a spreading agent with an agrochemical, various properties such as wetting, penetration, and fixation of the agrochemical are strengthened to increase the medicinal effect (Non-patent Document 1).

  So far, nonionic surfactants such as polyoxyethylene alkyl ethers, sorbitan fatty acid esters, polyoxyethylene alkyl ethers, polyether-modified silicones (Patent Documents 1 and 2), alkali alkylsulfosuccinates are used as spreading agents for agricultural chemicals. Anionic surfactants such as salts and alkali salts of dinaphthylmethanesulfonic acid (Patent Document 3) are used.

  However, when these spreading agents are used, properties such as wettability of the liquid are improved, but there is a problem that the rain resistance of the agrochemical component in the spray liquid with respect to the object is lowered.

  Moreover, since the spreading agent composition described in Patent Document 2 uses an alcohol solvent, it has an adverse effect on the environment or the human body, and further has a problem that the dispersibility in water is lowered.

  Therefore, a spreading agent that has excellent rain resistance and water dispersibility and is friendly to the environment and the human body is desired.
