Although numerous insecticides, miticides and other pest control agents have been used in the past, since their efficacy has been inadequate, their use has been limited due to problems with drug resistance, or they have caused damage or contamination of plant bodies or demonstrated potent toxicity against human beings, livestock or fish, there have been more than a few cases in which these conventional pest control agents were hardly considered to be satisfactory control agents. Thus, there has been a desire for the development of a chemical having few of these disadvantages that can also be used safely.

In addition, the compounds according to the present invention can also be used in plants that have acquired characteristics such as pest resistance, disease resistance or herbicide resistance and the like through gene recombination or artificial hybridization.
In addition, numerous pests such as diamondback moths, planthoppers, leafhoppers and aphids have recently developed resistance to organic phosphorous agents, carbamate agents and miticides, and problems have occurred regarding the inadequate effects of these chemicals, thus resulting in the desire for an effective chemical against resistant strains of pests and mites.

In addition, the pest control agent according to the present invention has low levels of chemical damage, low toxicity with respect to fish and mammals, and is highly safe.
In the case of an actual application of the pest control agent according to the present invention, although one type or two or more types of compounds according to the present invention can be used as is without adding other components, it is normally mixed with a solid vehicle, liquid vehicle or gaseous vehicle, or impregnated into a base material such as a porous ceramic plate or non-woven fabric, followed by the addition of a surfactant or other auxiliary agent as necessary, and is used by formulating into a form that can be adopted by ordinary agricultural chemicals for the purpose of use as an agricultural chemical, examples of which include wettable powders, granules, powders, emulsions, aqueous solutions, suspensions, water-dispersible granules, flowable preparations, aerosols, spraying agents, heat transpiration agents, smoking agents, poison bait and microcapsules.
In the case of using an additive or vehicle for the purpose of obtaining a solid agent, a plant-based powder such as powdered soybeans or powdered wheat, a mineral-based fine powder such as diatomaceous earth, apatite, gypsum, talc, bentonite, pyrophyllite or clay, or an organic or inorganic compound such as sodium benzoate, urea or sodium sulfate can be used. In the case of using for the purpose of obtaining a liquid agent, a petroleum distillate such as kerosene, xylene or solvent naphtha, or cyclohexane, cyclohexanone, dimethylformamide, dimethylsulfoxide, alcohol, acetone, methyl isobutyl ketone, mineral oil, vegetable oil, water, or the like can be used as a solvent. Examples of gaseous vehicles used in a spraying agent include butane gas, LG, dimethylether and carbon dioxide gas.

In the case of using the pest control agent according to the present invention in agricultural applications, the preparation form is in the form of a wettable powder, emulsion, suspension, flowable preparation, aqueous solution or water-dispersible granules, and can be used by diluting these preparations to a prescribed concentration with water to obtain a solution, suspension or emulsion, and then spraying a powder or granules directly onto plants or soil.
In addition, in the case of using the compound according to the present invention as a pest control agent for preventing disease, the preparation form thereof is in the form of an emulsion, wettable powder, flowable preparation, or the like, and these preparations can be applied by diluting to a prescribed concentration with water. In addition, the compound according to the present invention can be used directly in the case where the preparation form thereof is an oily agent, aerosol, spraying agent, poison bait or miticidal sheet.
In the case of using the compound according to the present invention as a pest control agent for controlling external parasites of livestock such as cows or pigs or pets such as dogs or cats, a preparation of the compound according to the present invention can normally be used according to a known veterinary method.
Examples of such methods include administration in the form of a tablet, capsule, permeating liquid, feed additive, suppository or injection (intramuscular, subcutaneous, intravenous or intraperitoneal injection) in the case of aiming systemic control, and administration by spraying, pouring or spotting an oily or aqueous liquid, or forming a resin preparation into a suitable shape such as that of a collar, ear tag, or the like to attach the resin preparation to the animal in the case of aiming non-systemic control. In this case, the preparation is normally used at the rate of 0.01 to 1000 mg of the compound according to the present invention per 1 kg of body weight of the host animal.
Although the miticidal agent according to the present invention naturally demonstrates adequate effects when used alone, it can also be mixed or used in combination with one type or two or more types of other miticidal agents, antimicrobial agents, insecticidal and acaricidal agents, herbicides, plant growth regulators, synergists, fertilizers, soil conditioners or animal feeds.
In addition, in the case of using the compound according to the present invention as an agricultural chemical, it may be applied after mixing with other types of herbicides, various types of insecticides, miticides, nematocides, antimicrobial agents, plant growth regulators, synergists, fertilizers or soil conditioners as necessary either during formulation or during spraying.
By applying after mixing with other agricultural chemicals or plant hormones in particular, reduced costs resulting from decreasing the amount of chemical applied, and a broader insecticidal spectrum and greater pest control effects due to the synergistic action of the mixed chemicals, can be expected.
