AZINPHOS-ETHYL

Химические свойства

Azinphos-ethyl forms colorless, clear crystals. It is insoluble in water, but soluble in most organic solvents. As an acaricide, azinphos-ethyl is used for the control of pests, such as, spider mites, aphids, caterpillars, potato bug, beetles, bollweevils, whitefl ies, bollworms, thrips, and other biting and sucking insects. Human exposures to azinphos-ethyl occur through absorption from the gastrointestinal tract, through the intact skin, and by inhalation of fi ne spray mist and dusts.
Azinphos-ethyl is a non-systemic organophosphorus insecticide, which is used against a relatively broad spectrum of insects. These include lepidopterous larvae, beetles and their larvae, aphids, jassids, and spider mites on various crops. And also crops of cotton, rice, sugar and fodder beets, fruits such as apples, pears, citrus-fruit, grapes; tobacco. Many countries around the world have stopped the use of this pesticide.

Использование

Azinphos-ethyl is used to control both chewing and sucking pests on a wide range of crops.

Общее описание

Colorless crystals. Used as a non-systemic insecticide with good ovicidal properties and long persistence. Used on cotton, citrus, vegetables, potatoes, tobacco, rice, and cereals to control caterpillars, beetles, aphids, spiders and many other insects. Not registered for use in the U.S.

Реакции воздуха и воды

Nearly insoluble in water. What little amount is solubilized will readily hydrolyze.

Профиль реактивности

The BPS Pesticide incident in Helena resulted in an explosion and death of three firemen. The burning of a 1,000 pound sack of Azinphos Methyl or the flashing of Maneb which was present on the facility may have caused the explosion. Azinphos Ethyl may behave similarly. At elevated temperatures, AZINPHOS-ETHYL will decompose generating toxic gases.

Угроза здоровью

The systemic effects of AZINPHOS-ETHYL are similar to parathion. It is an extremely potent systemic toxicant via ingestion, inhalation and skin contact. It may cause death or permanent injury after very short exposure to small quantities.

Пожароопасность

(Non-Specific -- Organophosphorus Pesticide, n.o.s.) When heated to decomposition, AZINPHOS-ETHYL emits very toxic fumes of sulfur, phosphorus and nitrogen oxides. Container may explode in heat of fire.

Профиль безопасности

Poison by ingestion, inhalation, skin contact, and intraperitoneal route. A cholinesterase inhibitor type of insecticide. When heated to decomposition it emits toxic fumes of SOx, POx,, and NOx. See also PARATHION.

Метаболический путь

Although the metabolism of azinphos-ethyl has been studied much less than that of azinphos-methyl, the biotransformations which have been reported appear to be totally analogous.

Меры предосторожности

Azinphos-ethyl is an organophosphorus compound that inhibits cholinesterase enzymes. It is very toxic and occupational workers should be very careful during use, storage, and waste disposal of it.
