Azocyclotin is a highly toxic chemical compound from the group of organotin compounds and nitrogen heterocycles .

Extraction and presentation

Azocyclotine can be obtained by reacting 1,2,4-triazole with tricyclohexyltin chloride (TCHT).

properties

Azocyclotin is a colorless solid that is poorly soluble in water. It decomposes above a temperature of 210 ° C.

use

Azocyclotin is used as an acaricide with a long duration of action against all mobile stages of spider mites in viticulture, fruit, vegetable and cotton cultivation. It was introduced as a mite control agent in 1977.

Admission

In the EU countries such as Germany and Austria as well as in Switzerland, no pesticides are permitted that contain azocyclotine as an active ingredient.
