In recent years, in order to increase the marketability and productivity of agricultural crops through forced, semi-forced or suppressed cultivation, so-called greenhouse cultivation, in which useful crops are grown under agricultural covering materials such as agricultural vinyl film, has been introduced. Tunnel cultivation is widely practiced. Most of the synthetic resin covering materials currently used in greenhouse cultivation and tunnel cultivation, such as vinyl chloride resin films, cover the inner surface of the covering material (the surface facing the inside of the greenhouse or tunnel).

In order to promote the flow of water droplets (the same applies hereafter) and increase the amount of sunlight incident, an antifogging agent (1), which is a type of surfactant, is used.
It mainly contains zorbitan fatty acid ester, glycerin fatty acid ester, etc.). However, under a covering material containing such an antifogging agent, in the morning, evening, and/or night when the temperature difference between the outside and outside of the covering material is large, or during rain, the inner surface of the covering material may The phenomenon of fog (or haze) is often observed. This fog phenomenon often occurs during the winter, which is the most important period for greenhouse cultivation, tunnel cultivation, and other facility cultivation.

We do not know exactly why this phenomenon occurs, but it is likely that the electrostatic properties of the moisture evaporating from the earth's surface and the degree of hydrophilicity of the wet surface of the covering material have subtle effects on each other. It is presumed that this is because the moisture inside the house or tunnel does not adhere to the surface of the sheathing material and flow smoothly due to temperature changes, and some of the moisture becomes atomized near the inner surface of the sheathing material. Ru. This fog generation phenomenon is caused by the formation of leaves, stems, flowers, etc. of crops grown in greenhouses or tunnels.
It wets the fruit and causes diseases such as downy mildew, gray mold, sclerotium, vine blight, scab, and bacterial spot.
Alternatively, it may help spread the disease, and furthermore, when cultivated crops get wet, the amount of heat required to dry them is required.
Disadvantages arise, such as a greater amount of fuel being required for heating the house or tunnel.

In order to eliminate this disadvantage, conventionally, colored agricultural vinyl films have been used to alleviate temperature changes inside greenhouses and tunnels, or intentionally dirty agricultural films have been used, or Mulching the soil inside the tunnel to reduce the amount of water evaporation, and changing the timing of irrigation (for example, watering late in the evening, controlling the area and amount of water to be irrigated, etc.)
Measures have been taken to improve the water rinsing method and equipment, but none of these measures have been effective in suppressing the fogging phenomenon.
