Fenobucarb is a chemical compound from the group of carbamates , its racemate as an active ingredient in plant protection products is used.

Extraction and presentation

Fenobucarb can be obtained by reacting 2 sec -butylphenol with phosgene to form 2 sec -butylphenol chloroformate , which reacts with methylamine to form the end product.

use

Fenobucarb is used as an insecticide in rice, sugar cane, tea, wheat and vegetable cultivation. Fenobucarb was and is not approved as an active ingredient in plant protection products in the EU. In Germany, Austria and Switzerland, no pesticides with this active ingredient are permitted.
