Dimefox is a chemical compound from the group of organic fluorine compounds and phosphoric acid amides .

Extraction and presentation

Dimefox can be obtained by fluorinating bis (dimethylamido) phosphoryl chloride.

properties

Dimefox is a colorless liquid with a fishy odor that can be mixed with water. It acts as an inhibitor of acetylcholinesterase .

use

Like the related compounds Schradan , Mazidox and Mipafox , Dimefox , which came on the market in 1940, is used as an insecticide . Dimefox was used against plant lice and spider mites , among other things . The active ingredient is absorbed and stored by the plant, where it remains effective for a long time.

However, it is classified as obsolete by the World Health Organization and is rarely used worldwide.

Admission

In the European Union, Dimefox is not included in Annex I of Directive 91/414 / EEC with Regulation (EC) No. 2076/2002 of November 20, 2002, so the active ingredient is no longer a plant protection product in the EU countries authorized. In Switzerland, too, no pesticides containing this active ingredient are permitted.
