When compounds (X) are used as the active ingredients of pesticide compositions, they may be used as such without addition of any other ingredients. However, they are usually used in admixture with solid carriers, hquid carriers and/or gaseous carriers, and if necessary, by addition of adjuvants such as surfactants, followed by formulation into various forms such emulsifiable concentrates, oil formulations, flowables, dusts, wettable powders, granules, paste formulations, microcapsule formulations, foams, aerosol formulations, carbon dioxide gas formulations, tablets, or resin formulations. These formulations may be used by processing into poison baits, shampoo, mosquito coils, electric mosquito mats, smokes, fumigants, or sheets.
In these formulations, compounds (X) are usually contained each in an amount of 0.1% to 95% by weight.
The sohd carrier which can be used in the formulation may include the following materials in fine powder or granular form: clays (e.g., kaolin clay, diatomaceous earth, bentonite, Fubasami clay, acid clay); talc, ceramic, and other inorganic minerals (e.g., sericite, quartz, sulfur, activated carbon, calcium carbonate, hydrated silica); and chemical fertilizers (e.g., ammonium sulfate, ammonium phosphate, ammonium nitrate, ammonium chloride, urea). The hquid carrier may include aromatic or aliphatic hydrocarbons
(e.g., xylene, toluene, alkylnaphthalene, phenylxylylethane, kerosine, light oils, hexane, cyclohexane); halogenated hydrocarbons (e.g., chlorobenzene, dichloromethane, dichloroethane, trichloroethane); alcohols (e.g., methanol, ethanol, isopropyl alcohol, butanol, hexanol, ethylene glycol); ethers (e.g., diethyl ether, ethylene glycol dimethyl ether, diethylene glycol monomethyl ether, diethylene glycol monoethyl ether, propylene glycol monomethyl ether, tetrahydrofuran, dioxane); esters (e.g., ethyl acetate, butyl acetate); ketones (e.g., acetone, methyl ethyl ketone, methyl isobutyl ketone, cyclohexanone); nitriles (acetonitrile, isobutyronitrile); sulfoxides (e.g., dimethylsulfoxide); acid amides (e.g., N,N-dimethylformamide, N,N-dimethylacetamide); vegetable oils (e.g., soy bean oil and cotton seed oil); plant essential oils (e.g., orange oil, hyssop oil, lemon oil); and water. The gaseous carrier may include butane gas, Freon gas, liquefied petroleum gas (LPG), dimethyl ether, and carbon dioxide.
The surfactant may include alkyl sulfate salts; alkylsulfonic acid salts; alkylarylsulfonic acid salts; alkyl aryl ethers and their polyoxyethylene derivatives; polyethylene glycol ethers; polyol esters; and sugar alcohol deri- vatives.
The other adjuvants may include binders, dispersants, and stabilizers, specific examples of which are casein, gelatin, polysaccharides (e.g., starch, gum arabic, cellulose derivatives, alginic acid), lignin derivatives, bentonite, sugars, synthetic water-soluble polymers (e.g., polyvinyl alcohol, polyvinylpyrrohdone, polyacryhc acid), PAP (isopropyl acid phosphate), BHT (2,6-di-t-butyl-4-methylphenoι), BHA (mixtures of 2-t-butyl-4-methoxyphe- nol and 3-t-butyl-4-methoxyphenoι), vegetable oils, mineral oils, fatty acids, and fatty acid esters.
The base material for resin formulations may include vinyl chloride polymers and polyurethanes. These base materials may contain, if necessary, plasticizers such as phthalic acid esters (e.g., dimethyl phthalate, di- octyl phthalate), adipic acid esters, and stearic acid. The resin formulations can be obtained by kneading the compounds into the base materials with an ordinary kneader and subsequent forming such as injection molding, extru- sion, or pressing. They can be processed, if necessary, though further forming and cutting into resin formulations in various shapes such as plates, films, tapes, nets, or strings. These resin formulations are processed as, for example, collars for animals, ear tags for animals, sheet formulations, at- tractive strings, or poles for horticultural use.
The base material for poison baits may include grain powders, vegetable oils, sugars, and crystalline ceUulose. If necessary, additional agents may be added, including antioxidants such as dibutylhydroxytoluene and nordihydroguaiaretic acid; preservatives such as dehydroacetic acid; agents for preventing children and pets from erroneously eating, such as hot pepper powder; and pest-attractive flavors such as cheese flavor, onion flavor, and peanut oil.
The pesticide compositions of the present invention may be used by, for example, direct apphcation to pests and/or apphcation to the habitats of pests (e.g., plant bodies, animal bodies, soil).
When the pesticide compositions of the present invention are used for the control of pests in agriculture and forestry, their apphcation amounts are usually 1 to 10,000 g/ha, preferably 10 to 500 g/ha. Formulations such as emulsifiable concentrates, wettable powders, flowables, and microcapsule formulations are usually used after dilution with water to have an active ingredient concentration of 1 to 1000 ppm, while formulations such as dusts and granules are usually used as such. These formulations may be directly apphed to plants to be protected from pests. These formulations can also be incorporated into soil for the control of pests inhabiting the soil, or can also be apphed to beds before planting or apphed to planting holes or plant bottoms in the planting. Further, the pesticide compositions of the present invention in the form of sheet formulations can be apphed by the methods in which the sheet formulations are wound around plants, disposed in the vi- cinity of plants, or laid on the soil surface at the plant bottoms.
When the pesticide compositions of the present invention are used for the prevention of epidemics, their apphcation amounts as active ingredient amounts are usually 0.001 to 10 mg/m3 for spatial apphcation or 0.001 to 100 mg/m2 for planar apphcation. Formulations such as emulsifiable concentrates, wettable powders, and flowables are usually apphed after dilution with water to have an active ingredient concentration of 0.01 to 10,000 ppm, while formulations such as oil formulations, aerosols, smokes, or poison baits are usually apphed as such.
When the pesticide compositions of the present invention are used for the control of external parasites on domestic animals such as cattle, sheep, goat, and fowl or small animals such as dogs, cats, rats, and mice, they can be used by the veterinarily well-known methods. As the specific methods of use, administration is achieved by, for example, tablets, feed incorporation, suppositories, or injections (e.g., intramuscular, subcutaneous, intravenous, intraperitoneal) for systemic control, or by, for example, spraying, pour-on treatment, or spot-on treatment with an oil formulation or an aqueous solution, washing animals with a shampoo formulation, or attachment of a collar or ear tag prepared from a resin formulation to animals for non-systemic control. The amounts of compounds (X) when administered to animal bodies are usually in the range of 0.1 to 1000 mg per 1 kg weight of each animal. The pesticide compositions of the present invention can also be used in admixture or combination with other insecticides, nematocides, acaricides, bactericides, fungicides, herbicides, plant growth regulators, synergists, fertilizers, soil conditioners, animal feeds, and the like.
