The method for controlling harmful arthropods of the present invention is conducted by applying an effective amount of the compound of the present invention to a harmful arthropod directly and/or a habitat thereof (for example, plant bodies, soil, an interior of a house, or animal bodies). In the method for controlling harmful arthropods of the present invention, the compound of the present invention is usually used in the form of a harmful arthropod controlling agent.
When an agent for controlling harmful arthropods of the present invention is used for controlling harmful arthropods in an agricultural field, the application dose as an amount of the compound of the present invention is usually within a range from 1 to 10, 000 g per 10, 000 m2. The emulsifiable concentrate, the wettable powder, or the flowable formulation etc. of an agent for controlling harmful arthropods of the present invention is usually applied by diluting it with water in such a way that a concentration of the active ingredient is within a range from 0.01 to 10,000 ppm. The granular formulation or the dust formulation etc., is usually applied as itself without diluting it.
These formulations and diluents of the formulations with water may be directly sprayed to a harmful arthropod or a plant such as a crop to be protected from a harmful arthropod, or applied to a soil in a cultivated area to control a harmful arthropod that inhabits the soil.
Also, a resin formulation processed into sheet shape or string shape may be wrapped around a crop, stretched near a crop, spread on a plant foot soil, or the like.
When the agent for controlling harmful arthropods of the present invention is used to control harmful arthropods that live inside a house, the application dose as an amount of the compound of the present invention is usually within a range from 0.01 to 1,000 mg per 1 m2 of an area to be treated, in the case of using it on a planar area. In the case of using it spatially, the application dose as an amount of the compound of the present invention is usually within a range from 0.01 to 500 mg per 1 m3 of the space to be treated. When the agent for controlling harmful arthropods of the present invention is formulated into emulsifiable concentrates, wettable powders, flowables, or the others, such formulations are usually applied after diluting it with water in such a way that a concentration of the active ingredient is within a range from 0.1 to 10,000 ppm, and then sparging it. In the case of being formulated into oil solutions, aerosols, smoking agents, poison baits, or the others, such formulations are used as itself without diluting it.
When the agent for controlling harmful arthropods of the present invention is used for controlling external parasites of livestock such as cows, horses, pigs, sheep, goats, and chickens, and small animals such as dogs, cats, rats, and mice, the pest control agent of the present invention can be applied to the animals by a known method in the veterinary field. Specifically, when systemic control is intended, the pest control agent of the present invention is administered to the animals as a tablet, a mixture with feed, or a suppository, or by injection (including intramuscular, subcutaneous, intravenous, and intraperitoneal injections). On the other hand, when non-systemic control is intended, the pest control agent of the present invention is applied to the animals by means of spraying of the oil solution or aqueous solution, pour-on or spot-on treatment, or washing of the animal with a shampoo formulation, or by putting a collar or ear tag made of the resin formulations to the animal. In the case of administering to an animal body, the dose of the compound of the present invention is usually within a range from 0.1 to 1,000 mg per 1 kg of an animal body weight.
