Ametryn is an organic compound that belongs to the nitrogen heterocycles and thioethers . The connection was first established by Geigy in 1964 .

presentation

The compound is usually obtained by nucleophilic aromatic substitution of atrazine with methanethiol and sodium hydroxide as the base . It is also possible to react atrazine with sodium disulfide in a solution of dimethyl sulfate in sodium hydroxide solution .

use

Ametryn is a herbicide that is used against large-leaved weeds and grasses mainly from maize , pineapple and sugar cane plantations . The competition usually takes place on the ground, less often by plane. The herbicide is absorbed by the plants through the leaves and roots. In these it mainly causes a disruption of photosynthesis .

No pesticides containing this active ingredient are permitted in the EU .
