ДИЕНОХЛОР

Использование

Dienochlor is used for the control of mites (Tetrunychus spp., Panonychus ulmi and Polyphagotarsonemus latus) on roses, Chrysanthemums and other ornamentals.

Экологическая судьба

Plant. On plants, dienochlor was converted by sunlight to form perchloro ketones (Quistad and Mulholland, 1983).
Chemical/Physical. Dienochlor is unstable when exposed to sunlight. When dienochlor applied as a thin ?lm on glass plates was exposed to sunlight, nonpolar products, a tricyclic chlorocarbon and 3 isomeric perchloro ketones were formed at yields
Dienochlor begins to decompose at 130°C (Worthing and Hance, 1991).

Метаболический путь

Dienochlor is readily degraded in sunlight to many products, only a few of which have been identified. It is also metabolised in animals but to unknown products. In vitro studies have shown that it interacts with thiols (glutathione, cysteine, efc.) and proteins.

Метаболизм

Dienochlor decomposes in simulated sunlight (DT₅₀ 1.6 min). Degradation is mainly environmental rather than metabolic, and photochemical breakdown is rapid. It decomposes in soils, DT₅₀ 3.1 days and DT₅₀ 2–3 days on plants exposed to sunlight.The major degradation products of dienochlor in plants are perchloroketones. It is rapidly degraded in rats.
