化学的特性

ethion is an odorless amber liquid. It is very sparingly soluble in water, but soluble in most organic solvents. Ethion undergoes decomposition on heating or on burning and produces toxic and corrosive fumes, including phosphorus oxides and sulfur oxides. It is used for the control of crop pests and household insects. These include, but are not limited to, aphids, mite, sticks, scales, thrips, leaf hoppers, maggots, leaf-feeding insects, foliar-feeding larvae, and house fl ies. It may be used on a wide variety of food, fi ber, and ornamental crops, including greenhouse crops, lawns, and turf. Ethion is often used on citrus and apples. It is mixed with oil and sprayed on dormant trees to kill eggs and scales. Occupational workers and the general public are exposed to ethion while working in industries that manufacture ethion and when eating raw fruits or vegetables that have been treated with ethion. There are no residential uses for ethion.

輸送ラベル（DOT）	Poison
火災危険	Shock can shatter the container, releasing the contents. Fire may produce irritating or poisonous gases. Decomposes above 302F. When heated to decomposition it emits highly toxic fumes of oxides of sulfur and phosphorus. Hydrolyzed by acids and alkalies. Slowly oxidized in air. (EPA, 1998)Combustible. Liquid formulations containing organic solvents may be flammable. Gives off irritating or toxic fumes (or gases) in a fire. Risk of fire and explosion if formulations contain flammable/explosive solvents.
健康有害性	This material is very toxicthe probable oral lethal dose for humans is 50-500 mg/kg, which is between one teaspoonful and one ounce for a 150-lb person. (EPA, 1998)
有害性の概要	Ethion is an organophosphate pesticide. Pure ethion is a clear to yellowish liquid with an unpleasant sulfur-like smell. It does not occur naturally in the environment. Ethion is used in agriculture, mainly to control insects on citrus trees, but also on cotton, fruit and nut trees, and some vegetables. It may also be used on lawns and turf grasses, but it is not used in the home for pest control.

用途

農薬(接触性殺虫、殺ダニ剤)

使用

Ethion is used to control mites and sucking insects, larval Lepidoptera and soil pests in a wide range of crops and in turf. An additional use is as an ectoparasiticide to control cattle ticks.
