Uses
Formerly in the control of woody plants on uncropped land.
Production Methods
Fenoprop-butometyl was produced through a classic “ester of an ester” route that mirrored other phenoxy herbicide derivatives of its era. Manufacturers began with technical-grade fenoprop, itself obtained by chlorinating and then etherifying the appropriate phenolic precursor to install the 2-propyl side chain. Once purified, this phenoxy acid was converted into its butoxyethyl ester by reacting fenoprop’s carboxyl group with 2-butoxyethanol under standard esterification conditions, typically using an acid catalyst and controlled heating to drive off water and prevent side reactions.
Mechanism of action
Synthetic auxin affecting nucleic acid biosynthesis and cell elongation. Systemic, selective.
Pesticide Type
Herbicide; Plant Growth Regulator
