Cinosulfuron is a chemical compound from the group of triazine yl sulfonylureas .

Extraction and presentation

Cinosulfuron can be obtained by reacting chlorobenzene with ethylene glycol methyl ether , chlorosulfonic acid , ammonia and phosgene .

properties

Cinosulfuron is a colorless solid that is insoluble in water. It is stable to hydrolysis at a pH of 7 to 10, but hydrolyzes at a pH of 3 to 5.

use

Cinosulfuron is used as a post-emergence herbicide against grass and broad-leaved weeds.

Admission

The EU Commission decided in 2004 not to approve the active ingredient cinosulfuron in the European Union. A transition period until June 2007 has been set for the use of cinosulfuron in rice cultivation in Italy and Spain.

In Germany, Austria and Switzerland, no pesticides with this active ingredient are permitted.
