JP6671880B2 - Spreading agent composition - Google Patents

Description

  The present invention relates to a spreading composition.

  Plant leaves, stems, and epidermis surfaces of insects have components or structures that repel liquids. For this reason, the sprayed pesticides may not adhere to the epidermis surface and may not show a sufficient effect.

  Therefore, by mixing a spreading agent with the pesticide, various properties of the pesticide such as wetting, permeation and sticking are strengthened to increase the medicinal effect (Non-Patent Document 1).

  So far, non-ionic surfactants such as polyoxyethylene alkyl ether, sorbitan fatty acid ester, polyoxyethylene alkyl ether, and polyether-modified silicone (Patent Documents 1 and 2), alkali alkyl sulfosuccinates have been used as pesticide spreading agents. Salts and anionic surfactants such as an alkali salt of dinaphthylmethanesulfonic acid (Patent Document 3) are used.

  However, when these spreading agents are used, the properties such as wettability of the liquid are improved, but there is a problem that the rain resistance of the pesticide component in the spray liquid for the target object is reduced.

  Further, 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 reduced.

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

2. 2. Weigh 10 g of the pesticide spreader into a 200 ml beaker and dilute with 40 g of distilled water. When a pesticide (Marathon Emulsion (Nissan Chemical Industries, Ltd.)) is used in combination, 10 g of the pesticide and 10 g of the spreader for pesticide are weighed in a 200 ml beaker and diluted with 30 g of distilled water.
4. One filter paper is immersed in the above-mentioned diluting liquid, and the liquid is sufficiently impregnated.
5. After hanging and drying at room temperature 25 ± 3 ° C. and humidity 55 ± 3% for 3 hours, the weight (B) is measured.
6. Place 300 mL of distilled water in a 300 mL beaker and completely immerse the dried filter paper for 10 minutes.
7. After drying for 24 hours under the same conditions as in 5 above (room temperature 25 ± 3 ° C., humidity 55 ± 3%), the weight (C) of the filter paper is measured, and the residual ratio is calculated by the following equation.

Residual rate (%): [(C)-(A)] / [(B)-(A)] × 100
Judgment ：: It is determined that there is rain resistance at a residual rate of 70% or more.

  X: It is determined that there is no rain resistance when the residual ratio is less than 70%.

Water dispersibility test 1 L of water was placed in a 1 L beaker, and 0.1 ml of each sample of each of Examples 1 to 19 and Comparative Examples 1 to 9 was put with a pipette, stirred with a glass rod, and allowed to stand still for 5 minutes to visually observe the dispersion state.
