Description

[Detailed description of the invention] Insect repellent for wood, preservative, and insect repellent for wood using the same, targeting pests that damage wood such as termites,
Concerning preservation methods.

In recent years, damage caused by pests that feed on wood, such as termite beetles and brown beetles, has become a problem. In order to prevent damage from these pests, materials have traditionally been treated with an appropriate insect repellent, and for this purpose, organochlorine insecticides such as thaloldane and dieldrin have been used as insecticidal and insect repellent ingredients.

However, all of these insect repellent components have drawbacks in terms of persistence, toxicity, irritation, environmental pollution, etc., and the development of low-toxicity insect repellents remains undesired.

On the other hand, in recent years, simultaneous treatment with insect repellents and preservatives has become common from the viewpoint of labor saving, and selection of an appropriate combination of insect repellents and preservatives has become an important issue.

By the way, according to the disclosure of Japanese Patent Publication No. 59-82309, it is proposed that an effectively soluble compound of an element selected from the group consisting of molybdenum and tungsten inhibits animals from fixing nitrogen. This discovery is as follows: 1. Molybdenum and tungsten are cheap.

2.It is safer than chrome or other metals.

8. Molybdenum and tungsten T are not toxic to pests other than nitrogen-fixing animals such as termites and carp beetles.
High selectivity.

4. It is slow-acting, so it is not repelled by termites etc.

5. Stable in various forms; In these respects, it is extremely useful as an insect repellent for wood.

The present invention Nagisa et al. further investigated the mixed use with preservatives from a practical standpoint, and found that a remarkable synergistic effect of insect repellent and preservative was observed with all conventional preservatives. Completed the invention. Although there are still many uncertainties regarding the mechanism of the synergistic effect, it is thought that molybdenum or tungsten compounds act as promoters in the process in which IIf and CCA compounds exhibit antibacterial activity. Insect repellent and antiseptic are two completely different physiological activities, and it is completely unexpected from conventional knowledge that the composition of the present invention exhibits a mutually synergistic effect.

Examples of the molybdenum and tungsten compounds used as insect repellents in the composition of the present invention include sodium molybdate (Na 2M0O4), molybdic anhydride (Mo0
3), molybdic acid (H2R(o04), ferrous molybdate (FeMo04), sodium tungstate (Na2WO4), ammonicum molybdate ((''4) 2M0207), and molybdenum ore. These salts are Although it is generally water-soluble, it can be easily converted into an insoluble compound by forming a complex with other inorganic or organic substances.

On the other hand, examples of preservatives that can be used in the composition of the present invention are as follows.

0CCA-based compounds - CCA, CCB, Forman salts, etc.

0-halofenol-based compounds - penchlorphenyl lacrate, p-bromo-2,6-dichlorophenol, dehydroabiethylamine I' CP, etc.

iodopropargyl compound-p-chlorophenyl-
3-iodopropargyl formal (IF-1000)
, haloprozin etc.

0 Quaternary ammonium compounds and amine salts - benzalconicum chloride, dialkyldimethylammonium chloride, trimyristylamine, etc.

(Organotin compounds - bis-(n-)liptyltin) oxide, tributyltin 7-di(L'-),) liphenyltin hydride oxide, tributyltin 7-malate, and the like.

Q Others - Zinc thenate, naphthenic acid.

8-oxyquinoline copper, xyligun aluminum salt, versider, amical.

TBP'4f The present invention is of course not limited to these preservatives, but provides a useful insect repellent and preservative for wood by combining it with an insect repellent containing a metal element compound of molybdenum and/or tungsten. All preservatives are included in the wood powder 1j as long as they do not depart from the spirit of the present invention.

The target pests to which the composition of the present invention is applied are pests that have nitrogen-fixing bacteria living symbiotically in their bodies, such as termites and carp beetles, and are particularly useful as termite control agents.

Another object of the present invention is to provide a method for preventing insects and preserving wood by applying the useful composition of the present invention.

As for the application method, conventional methods such as pressurized injection into wood, coating on wood, or treating the soil under and around the house can be used as is.
Furthermore, it is also possible to apply it as a termite-preventing bait agent, or as a termite-preventive coating agent by impregnating it with colored paint, varnish, or the like. When used as a bait agent,
Cellulosic materials such as cellulose tablets, tampons, water, paper, cardboard or cotton may be impregnated with the composition of the present invention along with an attractant if necessary.

The dosage form of the composition of the present invention includes insect repellent, preservative properties,
Depending on the purpose of use, oils, emulsions, aqueous phase agents, water sizing agents, powders,
Various formulations such as aerosol formulations are possible, and excellent synergistic effects were obtained with all formulations.

Hereinafter, the method for preventing insects and preserving wood using the composition of the present invention and the synergistic effect VC thereof will be explained using actual experimental examples.

Cough test example 1 ゜lXl Twenty worker termites, Yamato termites, were released and reared in petri dishes at 28±2°C and 90RH or above, and the number of dead insects at fixed intervals was counted.

At the same time, a treated test piece cut thinly on the 1X1X0.3 side was placed on agar inoculated with Trichoderma and Viridi spores, and heated at 28±2°C and 190RH for 14 hours.
After culturing for one day, the growth state of the mold on the test piece was observed. For comparison, test wood pieces treated with 2% sodium monomolybdate alone and those treated with the CCA compound alone were also observed. As a result of the test, the termicidal activity of the composition of the present invention was extremely superior to that of sodium molybdate alone, and on the other hand, the antiseptic activity was also superior to that of the CCA compound alone, and a high synergistic effect was observed.

Test Example 2゜To 2 parts of molybdenum ore and 1 s of pentachlorophenyl roughrate, 20 volumes of Tsurupol Sλ1-200 (registered trademark of Toho Chemical) and Kijirol 77 (116) were added, and these were mixed and dissolved with thorough stirring to obtain the emulsion of the present invention. This emulsion was diluted 10 times with water, and a 1X1X20σ translocator was immersed in this solution, and then buried near a nest of termites.After about 6 months, the state of feeding damage and the growth of mold were investigated.

As a result of the test, the composition of the present invention was found to contain molybdenum ore as a control,
A high synergistic effect was observed in termite prevention and antiseptic effects compared to pentachlorphenyl laflate.

Next, we investigated whether this synergistic effect was specific to insect repellents containing the metal elements molybdenum and tungsten.
In Test Example 2, a similar trial IMT was conducted by replacing the molybdenum ore with chlordane. The results are shown below.

As a result of trials, although chlordane was highly effective against termites,
No particular synergistic effect was observed in combination with pentachlorphenyl 2 chloride, confirming the usefulness of the composition of the present invention.

The composition of the present invention may contain other types of insect repellents, such as organic tJ such as thaloldane and dieldrin, pyrethroid agents such as hermethrin and fenvalerate, organic phosphorus agents such as fenitrothion, and carbamate agents, Alternatively, it is of course possible to use it in combination with nematicides, fertilizers, and other agricultural chemicals, and a multipurpose composition with excellent effects can be provided.
