Description

[Detailed description of the invention] <Industrial application field> The present invention relates to pest control compositions.

<Prior Art> Conventionally, it has been known to use a drying agent separately in order to prevent the solidification of the preparation.

<Problems to be Solved by the Invention> Conventionally, in order to prevent the formulation from caking, a desiccant was separately used in the container for the formulation, but the formulation itself would cause caking. Therefore, during and after pest control work, the formulation solidifies due to moisture due to rain, etc., resulting in a decrease in commercial value and a significant drop in activity against pests.

The object of the present invention is to obtain a pest control composition that eliminates the above-mentioned conventional problems.

<Means for Solving the Problems> The present invention relates to a pest control composition characterized in that a pest control agent is blended with a pest control component.

<Function> By blending the above-mentioned water repellent with a pest control component, the present invention has an excellent anti-assimilation effect and a strong pest control effect.

In the present invention, the pest control components include pyrethroid compounds, carbamate compounds, dracin compounds,
Any compound having an insecticidal, termiticidal or acaricidal effect, such as an organic phosphorus compound, a boron compound, or a silicon compound, may be used alone or in combination. To name a few, pyrethrin, allethrin, flamethrin, resmethrin (A-8), phthalthrin, phenothrin (A-3), vermethrin

and hydrazone compounds such as fatty acid salts thereof, boric acid (
Examples include boric acid compounds such as A-r9).

The powder/bulk carrier used in the present invention is typically, for example, silicic acid, activated carbon, bentonite, diatom (C-3
), talc (C-1), clay (C-2), calcium carbonate, carbon black, various minerals and powders such as ceramic powder, various vegetable powders such as wood flour, soybean flour, wheat flour, starch, or cyclodextrin. Examples of packaging compounds include IN or two or more of them may be mixed as required.

One or more commonly used bactericidal agents, repellents, insecticides, attractants, potency enhancers, etc. may be used in combination with the above compounds, and stabilizers, antifungal agents, fragrances, etc. may also be optionally added. I can do it.

In the present invention, water repellents include paraffin, aluminum stearate, curconium stearate, magnesium stearate, silicone resin, and reactive long-chain saturated hydrocarbon compounds (e.g., pyridinium salt type cationic surfactants). , methylol stearamide, octadecyl ethylene urea'S) reactive silicone compounds (e.g. methylhydropolysiloxane, etc.), polymers with perfluoroalkyl groups in side chains (e.g. acrylic acid polyfluoroalkyl ester (B-4) products) Scotchgard, 3M?t[), silicone oil with dimethylpolysiloxane structure (product name KF

The addition rate of the above water repellent is approximately 0.001 to 0.001 to the dry weight of the formulation.
Can be added at a rate of 50%, preferably 0.4%
It is better to add more than that.

Directly mix and stir at least one of the pest control ingredients, a water repellent (C), a bulking agent (Q), or a water repellent (
In order to enhance the dispersion of (b), the water repellent (b) is diluted in advance with a solvent, added to at least one insect control ingredient^ and 0 fillers, thoroughly mixed and stirred, and then the solvent is immediately distilled off. In this way, the pest control composition (powder) of the present invention as shown in Table 1 below was obtained.

, 3f were each sprayed and air-dried, and this process was repeated orally.

As a result, after repeating the test four times, it was confirmed that the surface of the control treated with 3F of water had become lumpy, whereas the surface of the control of the present invention was found to maintain a fine powder. .

Test Example 2 Example Arashi 4 listed in Table 1 was mixed with water at a ratio of 1:1, the 13F paste was placed in a 93-diameter Petri dish, and the paste was dried for 24 hours. One house termite was released per petri dish. Processing time is 1
The duration was 0 seconds and 1 minute. Thereafter, it was transferred to an untreated Petri dish. Then I observed the time it took for him to suffer. The test results are also listed in Table 2 below, with Comparative Examples &, Comparative Examples, and No Treatment as Comparative Examples.

〇 -1 minute 5 0 0 - No clam 11j 5 0
0 - As is clear from the results in Table 2 above, the insecticidal activity against termites of the present invention was significantly higher than that of the comparative example.

Test Example 3 In a Petri dish prepared by the method described in Test Example 2, one dried preparation and one domestic termite were released. After that, I observed how long it took for them to start suffering. As a comparative example, the test results are also listed in Table 3 below.

Comparative example a I 7 100 20-35±6.
40 Comparative Example c 10 0 - No treatment
10 - As is clear from the results in Table 3 above, the degree of solidification of the products of the present invention was weaker than that of the comparative example, so the powder easily adhered to the surface of the house termite body, and the time required for insecticidal activity to be achieved was faster.

Test Example 4 Using the powder of Example Tooth 18 listed in Table 1 above, an insecticidal efficacy test was conducted against adults of woodlice, pillbugs, black-bellied beetles, and yellow millipedes in the following manner. Inner diameter 1
Soil 501 grated with Kendo was placed in a 2 cm large petri dish. Put the above powder in it, per door, eye f, 201
．． 401, and 10 ml of water was evenly dropped onto the treated surface in each treatment section. The control group was conducted in the same manner as the powder formulation described above, except that only the carrier was used (no drugs or water repellent added).

The above test insects were released on the treated surface at the start of the test in each treatment area. In this case, the number of test animals is 1 ward, 2
It was held in consecutive districts.

Immediately after the treatment and 10 days later, the number of knockdowns and the number of deaths were observed and evaluated at each elapsed time after the treatment. The results obtained are listed in Table 4 below.

It had superior residual efficacy and more immediate insecticidal activity than other commercially available drugs.

Test Example 5 An insecticidal efficacy test against young American cockroach larvae was conducted using the chemicals listed in Table 5 below in the following manner. Diameter 1
Two pieces of filter paper with a diameter of 9 c1M were placed in a 1.7 cPI polycup, and the drug was applied thereto at a rate of 10 nos per 1 d. After treatment, 21 hours of water was added dropwise, and 10 young American cockroach larvae were released into a polycup. After a predetermined period of time, the solid was observed to be knocked down or in agony.

The results obtained are shown in Table 6.
