Description

  The present invention relates to a photocatalytic animal and plant protective agent capable of protecting animals and plants from harmful organic compounds and the like.

  Chemical pesticides such as organophosphorus, organochlorine, and organomercury are almost all of the pesticides that control animal and plant diseases, viruses, molds, and bacteria. When using it, it is necessary to use different pesticides depending on the disease and the type of fungus.

Therefore, it is costly to spray multiple pesticides over and over, and repeated use reduces resistance and effectiveness, and chemically synthesized pesticides accumulate in animals and plants. There is also a problem that it often has an adverse effect.

None of the conventional agricultural materials have the ability to decompose environmental hormones, dioxins, chemically synthesized pesticides, etc., which are said to be environmental pollutants.

There is no material that can be used safely, easily, environmentally, or in animals and plants that has low running costs and is capable of degrading organic compounds, viruses, molds, and bacteria.

The photocatalytic animal and plant protection agent of the present invention is an animal and plant protection agent capable of protecting animals and plants from various environmental pollutants and the like, and is a photocatalytic animal and plant protection agent containing titanium dioxide. The photocatalyst type animal and plant protection agent of the present invention is a substance that decomposes and protects harmful substances by undergoing a photocatalytic reaction when exposed to ultraviolet light without being changed or decomposed. Make it easy for farmers to dilute and disperse the titanium dioxide at the site where it is used.

  Applications of photocatalysts have been developed all over the world for the purpose of sterilization, deodorization, decomposition purification, etc. due to their strong oxidizing power. In the photocatalyst of titanium dioxide, electrons and holes are generated on the surface by irradiation with light of a wavelength of 300 to 400 nm, particularly with ultraviolet rays, and an oxidation-reduction reaction occurs. Therefore, photocatalysts are used in air purifiers, tiles, protective walls, lamps, etc. that oxidize and decompose organic compounds by the oxidation-reduction reaction to normalize air.

When titanium dioxide undergoes a photocatalytic reaction, ultraviolet rays can be cut by utilizing the wavelength of 300 to 400 nm of ultraviolet rays, which can also be used for temperature adjustment inside the facility for facility cultivation or the like. The UV-blocking action is also used for women's cosmetics, automobile glass, clothing materials for facility cultivation, and the like.

Does not contain chemically synthesized emulsifiers, dispersants, surfactants, auxiliary ingredients, etc. By using titanium dioxide that can be safely used for animals and plants in the environment as a photocatalyst, it combines chemical removal with harmful organic compounds such as agricultural chemicals, environmental pollutants, various odorous components, and antibacterial, bactericidal, and viral decomposition. The use of pesticides can be reduced, and for use on roofs, exterior walls, etc. in facility cultivation, etc., the high-temperature damage of crops in the facility due to UV protection is suppressed, and some pests act with UV light There can be things to minimize the damage of such pests.

Since it does not contain chemical synthesis auxiliary ingredients when sprayed on animals and plants, add 0.01% to 10% as a spreading agent, etc., which is safe for human animals, animals and plants, etc. Spraying is preferred.

When spraying on the roof, outer wall, workplace, etc. of the facility, it is preferable to add 1% to 30% as a bonding agent for woodworking to a diluted solution of titanium dioxide and carefully spray so that there is no unevenness.

Like conventional emulsions, wettable powders, flowables, sols, etc. of agricultural chemicals, they can be easily dispersed on the site where they are used, so that they can be easily sprayed on farming machines, etc. I can do it now. For this reason, crops that are exposed to ultraviolet rays can be used without being selected for crops and diseases.

In the sterilization and antibacterial effect of strawberry powdery mildew, when sprayed on July 15, the white lesion of powdery mildew turned reddish brown on the next day, and on December 20, the color changed after 4 to 5 days. The second spraying was better on the 7th to the 10th, and after 14 days it was partially recurred. In addition, in the case of cucumber's powdery mildew and downy mildew, once sprayed, it was good to leave the spraying interval about 14-20 days. However, spraying once or twice a month is desirable. An effect that cannot be obtained with ordinary chemically synthesized pesticides was obtained. This has made it easier than ever to reduce pesticide-free and pesticide-free cultivation.

By coating the roof and outer walls of a greenhouse, glass greenhouse, etc. with titanium dioxide, the ultraviolet rays are cut and the temperature inside the facility can be lowered by 3 to 6 degrees, and the high temperature damage of plants is alleviated and grown. Promoted good quality crops from May to July. In addition, some insect pests were blocked by UV rays, and the damage caused by the insects was suppressed.

From the viewpoint of safe production of agricultural products, it is speculated that there is no limit to the possibility of use in agriculture, forestry, and civil engineering in terms of use in the agricultural field, environmental purification, and removal of pollutants.
