Overview
Picolinafen is a pyridinecarboxamide resulting from the formal condensation of the carboxy group of 6-(m-trifluoromethylphenoxy)picolinic acid with the amino group of p-fluoroaniline. A carotenoid biosynthesis inhibitor, it is used as a herbicide for the control of broad-leaved weeds in cereal crops. It has a role as a carotenoid biosynthesis inhibitor, a herbicide and an agrochemical. It is a pyridinecarboxamide, an aromatic ether, a member of (trifluoromethyl)benzenes and a member of monofluorobenzenes.
