It inhibits the biosynthesis of essential branched-chain amino acids valine and isoleucine, which prevents cell division and the plant growth is stopped. It is used as a herbicide in the cultivation of cereals (wheat, barley and triticale ) and can be applied before or after the emergence of the weeds. "}]
