Description

Spreader composition Invention field

The present invention relates to a spreader composition.

Background of the invention

The leaves and stems of plants and the epidermis of insects have components or structures that can repel liquids. Therefore, the sprayed pesticide cannot adhere to the above-mentioned skin surface, and may not exhibit sufficient effects.

Therefore, currently, a spreading agent is blended with a pesticide to enhance the wetting, penetration, and fixation properties of the pesticide to increase the efficacy (Non-Patent Document 1).

Hitherto, nonionic surfactants such as polyoxyethylene alkyl ether, sorbitan fatty acid ester, polyoxyethylene alkyl ether, polyether modified silicone, etc. (Patent Documents 1 and 2), alkane Anionic surfactants (Patent Document 3) such as alkali sulfosuccinic acid alkali metal salt and dinaphthyl methanesulfonic acid alkali metal salt (Patent Document 3) are used as spreading agents for agricultural chemicals.

However, when these spreading agents are used, although the wettability and other properties of the liquid are improved, there is a problem of poor rain resistance of the pesticide components in the spray liquid sprayed on the object.

In addition, the spreading agent composition described in Patent Document 2 uses Alcohol solvents have adverse effects on the environment or the human body, and even have the problem of poor water dispersion.

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