Description

Detailed Description of the Invention [Industrial Application Field] The present invention effectively uses 1-(jodomethylsulfonyl)4-methylbenzene and 2-(4-ethoxyphenyl)-2-methylpropyl-3-phenoxybenzyl ether. The present invention relates to a bactericidal/insecticide composition containing the present invention as an ingredient.

[Prior art]

Conventionally, household or various industrial products such as wall covering materials, textiles, and plastic products1. Adding antibacterial and antifungal agents or insecticides to organic glues, emulsion paints, or their raw materials, or alternatively, dissolving antibacterial and antifungal agents or insecticides in suitable dispersion media. Alternatively, by dispersing and coating these products or the surface to be coated, it has been carried out to impart an antibacterial, antifungal or insect repellent effect to these products or the surface to which they are applied.

As antibacterial agents, collectors of heavy metals such as mercury and tin, or organic compounds have been widely used, but although these compounds have excellent bactericidal effects, they are highly toxic to humans and livestock, causing problems when used. Furthermore, there is a large risk that it may remain in the used product and cause secondary damage, and it is also unsuitable for use due to pollution problems such as environmental pollution caused by wastewater and waste.

The non-metallic fungicides that have appeared in place of this have limited scope of use and do not have sufficient antifungal effects.

Organic phosphorus agents, carbamate agents, and the like are used as insecticides, but many of them are relatively toxic to humans and livestock and have a bad odor, making them particularly unsuitable for use in household products.

Furthermore, when these compounds are added to industrial products,
In many cases, the pest control effect is not sufficient, resulting in product contamination or deterioration due to pest breeding.

1-(jodomethylsulfonyl)-4 used in the present invention
-Methylbenzene (trade name: Amical) is already used as an industrial fungicide in the United States. Also 2-(4-
Ethoxyphenyl)-2-methylpropyl-3-phenoxybenzyl ether is already used in Japan as an agricultural insecticide and an insecticide for epidemic prevention (trade name: Trebon; Mitsui Toatsu Chemical ■), and is extremely safe. Known as an insecticide.

However, the action of these active compounds is only a bactericidal or insecticidal effect when used alone, and it is not possible to simultaneously control damage caused by contaminating bacteria and pests to various industrial products.

[Problems to be Solved by the Invention] The present invention solves the problem when attempting to obtain a bactericidal, fungicidal or insect repellent effect by adding the above-mentioned conventional fungicides or insecticides to household or industrial products. It is an object of the present invention to provide a fungicidal and insecticidal composition that overcomes the resulting drawbacks and has extremely excellent properties.

In other words, we are developing an extremely safe industrial fungicide that can simultaneously control a wide variety of fungi and pests that cause contamination and deterioration of household or industrial products over a long period of time at lower doses. The challenge is to provide.

[Means for solving problems]

In order to solve the above problems, various combinations of a large number of fungicides and insecticides were investigated. As a result, when the fungicidal and insecticide of the present invention is actually added to household or industrial products, it not only exhibits a wide spectrum of effects that would be unmatched by each active compound alone, but is also surprising. The present invention was completed based on the discovery of a synergistic effect that shows excellent bactericidal effects against various fungi over a long period of time.

That is, the present invention provides 1-(jodomethylsulfonyl)-4
-Methylbenzene and 2- (4-ethoxyphenyl)-
This is a bactericidal/insecticide composition characterized by containing 2-methylpropyl-3-phenoxybenzyl ether.

When the fungicidal insecticide of the present invention is added to household or industrial products, it can kill Aspergillus, Penicillium, Lycoderma, which often occurs in paints, pastes, wood and bamboo products, textiles, etc.
Mold such as Alternaria trichodersa, which often occurs on the surface of emulsion paints, artificial leather, cloth walls, etc.
molds such as or), and Staphylococcus molds that grow in latex emulsion mushrooms and cutting oil.
In addition to controlling bacteria such as C.occus and Bacillus for a long time, it can also control many sanitary pests such as cockroaches, houseflies, Culex mosquitoes, fleas, mites, and lice.

The mixing ratio of the two active ingredients in the fungicidal and insecticidal composition of the present invention is not particularly limited and can be varied within a relatively wide range.

-i preferably contains, for example, 0.01 to 50 parts by weight of 2-(4-ethoxyphenyl)-2-methylpropyl 3-phenoxybenzyl ether per 1 part by weight of 1-(jodomethylsulfonyl)-4-methylbenzene. is 0.
The composition of the present invention, which can be used in a range of 1 to 10 parts by weight, includes:
Although it can be used directly, it can also be used by appropriately dispersing it in a carrier, or by mixing it with a suitable solid carrier.

Furthermore, dispersants, suspending agents, spreading agents, wetting agents, stabilizers, etc. are added to these as necessary to form wettable powders, powders, granules, etc.
It may also be used in the form of a paste, suspension, spray, fumigation, or smoke.

The liquid carrier used in the &It product of the present invention may be any liquid as long as it does not react with the active ingredient, such as water, alcohols, (such as ethanol ethylene glycol), ketones (methyl ether ketone), and ethers ( Dioxane, Cello 9 Rub, etc.), aliphatic hydrocarbons (kerosene, gasoline, etc.), aromatic hydrocarbons (toluene, xylene, etc.), halogenated hydrocarbons (chloroform, dichloroethane, etc.), esters (acetic acid ethyl ester, etc.) ), diethylene glycol monomethyl ether, diethylene glycol monomethyl ether, etc. can be used.

In addition, inorganic solid carriers such as clay, talc, bentonite, and kaolin, and gas carriers such as halogenated hydrocarbons such as butane, propane, nitrogen gas, carbon dioxide, and chlorofluorocarbon gas can also be used.

Furthermore, as adjuvants to further enhance the formulation effect, ionic and nonionic surfactants, as well as vinyl acetate,
A polymer compound such as methylcellulose can be used in combination. Furthermore, when the composition of the present invention is applied as a bactericidal insecticide, it may be used in combination or as a mixture with other fungicidal and fungicidal agents or other agricultural chemicals such as bactericides, insecticides, herbicides, colorants, fragrances, etc. You can also do that.

The composition of the present invention can be treated by methods such as impregnation, poultice application, or mixing with the base material, depending on the characteristics and usage conditions of houses, fittings, furniture, household goods, various industrial products, and raw materials. For example, walls and ceilings in ordinary homes,
Antibacterial, mold and insect repellent for tatami mats, floors, carpets, furniture, etc.
It is also suitable as an anti-mold and insect repellent for many industrial raw materials and products such as paints, resins, pastes, adhesives, wood and bamboo products, leather, and fibers.
