General formula (I) (wherein, X and or an alkoxy group; a carboxyl group; an alkoxycarbonyl group; or a phenyl group which may be substituted with a halogen atom, and Xt and X4 are a hydrogen atom or an alkyl group,
Xl and It is known from European Patent Publication No. 146,748 that it exhibits a control effect against mites, nematodes, etc., and on the other hand, other specific compounds are also effective as pest control agents. This is well known.

[Background of the invention]

Although the compound represented by the general formula (I) generally has a high control effect on nematodes, it may not have such a high control effect on insects, mites, etc., and organic phosphorus compounds, Carbamate-based compounds, pyrethroid-based compounds, urea-based compounds, sulfone-based compounds, or N-pyridylaniline-based compounds may exhibit only a practically insufficient control effect against harmful animals depending on the application situation.

The present inventors have demonstrated that by applying a specific compound to the compound represented by the general formula (I), a synergistic control effect can be obtained compared to when each agent is applied alone, and the dosage can be reduced. It was found that the application situations of each drug will be expanded because the effects of reducing the number of pests and expanding the control spectrum can be obtained.

It is also effective in controlling fleas, lice, flies, etc. that parasitize livestock, etc., as well as cat nematodes, cyst nematodes, nematode nematodes, rice nematodes, strawberry nematodes, pine tree nematodes, etc. The pest control agent of the present invention has excellent permeability, so it can be applied to the soil. By doing so, it is possible to control insects harmful to the soil, mites, nematodes, gastropods, and isopods, and at the same time, pests living in the stems and leaves can be controlled.

When using the pest control agent of the present invention, it can be used in various forms such as emulsions, powders, granules, wettable powders, liquids, aerosols, pastes, etc., together with pesticide auxiliaries, as in the case of conventional pesticide formulations. The compounding ratio of these ingredients is usually 0.5 to 90 parts by weight of the active ingredient and 10 parts by weight of the agricultural chemical adjuvant.
~99.5 parts by weight.

When these preparations are actually used, they can be used as they are, or they can be diluted to a predetermined concentration with a diluent such as water.

The agrochemical auxiliaries mentioned here include carriers, emulsifiers, suspending agents, dispersants, spreading agents, penetrating agents, wetting agents, thickeners, stabilizers, etc., and may be added as appropriate if necessary. They are divided into solid carriers and liquid carriers. Solid carriers include starch, activated carbon, soybean flour, wheat flour, wood flour, fish meal, animal and vegetable powders such as milk powder, talc, kaolin, bentonite, calcium carbonate, zeolite, and diatomaceous earth. Examples of liquid carriers include water, alcohols such as methyl alcohol and ethylene glycol, ketones such as acetone and methyl ethyl ketone, dioxane,
Ethers such as teirahydrofuran, aliphatic hydrocarbons such as kerosene and kerosene, aromatic hydrocarbons such as xylene, trimethylbenzene, tetramethylbenzene, cyclohexane, and solvent naphtha, and halogenated hydrocarbons such as chloroform and chlorobenzene. , acid amides such as dimethylformamide, esters such as ethyl acetate and glycerin ester of fatty acids, nitrites such as acetonitrile, and sulfide-containing metals such as dimethyl sulfoxide.

In addition, other agricultural chemicals such as insecticides, acaricides, nematicides, fungicides, antiviral agents, attractants, herbicides,
It can be mixed or used in combination with plant growth regulators, etc., and may exhibit even better effects in this case.

The pest control agent of the present invention generally has a content of 1 to 20,0 OOpp.
It is preferably applied at an active ingredient concentration of 20 to 2,000 ppm. The concentration of these active ingredients can be changed appropriately depending on the form of the preparation, application method, purpose, timing, location, pest outbreak status, etc. For example, in the case of aquatic pests, a chemical solution with the above concentration range can be sprayed on the outbreak site. However, the concentration range of the active ingredient in water is below the above range.

The application amount per unit area is about 0.1 to 5.000 g, preferably 10 to 1 g, as the active ingredient compound per 10 a.
,000. is used.

However, in special cases it is also possible to depart from these ranges. Moreover, the compounding ratio of the compound represented by formula (I) and other specific compounds is 0.1 to 100:
0°005-100, preferably 1-50:0.01
~50.

The various formulations containing the compounds of the present invention or their diluents can be applied by commonly used application methods, such as scattering (e.g., scattering, spraying, misting, atomizing, dusting, surface application, etc.); Soil application (mixing, irrigation, etc.)
It can be carried out by surface application (painting, powder coating, coating, etc.), immersion of poison bait, etc. Also, the so-called ultra-high concentration small amount spraying method (
It can also be applied at ultralow volumes. In this way, 100% active ingredient content is possible.
