Description

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 herbicide, an agrochemical and a carotenoid biosynthesis inhibitor. It is a pyridinecarboxamide, a member of (trifluoromethyl)benzenes, an aromatic ether and a member of monofluorobenzenes.
