Abstract

PURPOSE:To provide the title agent active to indoor Tarsonemidae at low dosage along with its ovicidal activity for the mite, also serving as a fumigant, containing 3-iodo-2-propynylbutyl carbamate. CONSTITUTION:The objective mite-controlling agent or mite-controlling fumigant containing, as active ingredient, pref. 0.1-50 (esp. 0.1-20) wt.% of 3-iodo-2- propynylbutyl carbamate. The present agent may be used by mixing with other bactericide(s) and/or insecticide(s). The 3-iodo-2-propynylbutyl carbamate can nearly perfectly control up to the indoor Tarsonemidae in 'tatami' or carpets at low dosage; furthermore, it can kill not only adult mite but also its ova, thus effectively preventing mite recurrence.

Description

Detailed Description of the Invention: "Industrial Application Field" The present invention relates to a mite control agent and a mite control method, and more particularly, it is characterized by containing 3-iodo-2-propynylbutyl carbamate as an active ingredient. In particular, the present invention relates to a mite control agent and a mite control method that are highly effective in controlling indoor dust-borne goo and killing the eggs of the mites.

``Conventional technology'' Traditionally, drying tatami and carpets has been considered the most effective means of controlling mites that occur inside houses, but these methods are extremely difficult to implement due to space and labor requirements. Therefore, chemical control using drugs is generally used.

Conventionally used drugs include organophosphorus drugs such as fenthion, fenitrothion, diazinon, and DDVP, lychlorfon, pyrethroids such as chrythrone and permethrin, and carbamate propoxur.

However, in environments such as tatami mats and carpets where indoor dust mites live, uniform treatment of chemicals is often difficult.
Also, because spraying indoors is dangerous, the amount used had to be reduced.

Furthermore, conventional chemicals have poor ovicidal effects, which is one of the causes of mite re-emergence after chemical treatment. Therefore, many of the currently used mite control agents could not be expected to have a large control effect on indoor dust mites.

The indoor dust mites referred to here include Dermatophagoides mites, Dermatophagoides nigricans, Woolly spider mites, Isa salad mites, Physcomitrella sinensis mites, Aphthalmos mites, Sugar mites, Stag mites, Grass mites belonging to the genus Keracharobsis, Porphyra mites, House mites, and the like.

"Problems to be Solved by the Invention" In view of these circumstances, the present inventor has developed a mite control agent that is effective against indoor dust mites at a low dose and also has an ovicidal effect on these mites. As a result of intensive research,
The inventors have discovered that all of these points can be solved by using 3-iodo-2-propynylbutyl carbamate, and have completed the present invention.

"Means for Solving the Problems" Therefore, the gist of the present invention is that 3-iodine-2
- A tick-controlling agent and a tick-controlling smoke agent characterized by containing propynyl butyl carbamate as an active ingredient, and a tick-controlling method using these.

In addition, when using 3-1-)'-2-propynylbutyl carbamate as a mite control agent for indoor dust mites, it may be used as it is without adding any other ingredients. It can be mixed with various solid, liquid, and gaseous carriers used in general medicines, formulation auxiliaries, baits, etc. to produce oils, emulsions, powders, granules, wettable powders, aerosols, sheet preparations, etc. It can also be manufactured.

The carriers used in the formulation may be used alone or in combination. Examples of solid carriers include talc, clay, bentonite, kaolin, diatomaceous earth, calcium carbonate, urea, ammonium sulfate, white carbon, activated carbon, and wood. Examples of liquid carriers include powders and granules such as powder and starch, and examples of liquid carriers include aliphatic hydrocarbons such as kerosene and kerosene, aromatic hydrocarbons such as xylene, methylnaphthalene, toluene, and benzene, dichloroethane, and trichloroethylene. halogenated hydrocarbons such as ethanol, isopropanol, cellosolve, ketones such as acetone, methyl ethyl ketone, ethers such as diethyl ether and tetrahydrofuran,
Examples of the carrier include esters such as ethyl acetate, nitriles such as acetonitrile, amides such as dimethylformamide, vegetable oils such as soybean oil and cottonseed oil, and examples of the gaseous carrier include chlorofluorocarbon gas, LPG, and dimethyl ether. Examples of formulation auxiliaries include surfactants such as alkyl sulfate salts, polyoxyethylene sorbitan esters, and polyoxyethylene alkyl ethers, film forming agents such as cellulose derivatives, vinyl resins, polyvinyl alcohol, CMC, and gum arabic. Examples include thickeners or dispersants, foaming agents, combustion agents, etc.

In formulation, the mixing ratio is generally 0.1 to 50%, preferably 0.1 to 20% by weight of the compound of the present invention.
%, the optimal amount is 50-99.9% as a carrier and 0-15% as an adjuvant.

In addition, when actually using the present invention, how to use it,
It goes without saying that the amount of active ingredient to be used is 0.05 to 5 g, preferably 0.5 to 2 g per 1 d of the active ingredient, although it is a matter of course that it is selected appropriately depending on the dosage form used, the place of use, etc.

Furthermore, it is also possible to use it in combination with an organophosphorus-based, pyrethroid-based, carbamate-based bactericide or insecticide.

The present invention will be explained in more detail below using formulation examples and test examples, but the present invention is not limited thereto.
