Carfentrazone is an aryl-triazoline herbicide, used for pre-crop-establishment control of broadleaf weeds, including marshmallow, annual nettles, and volunteer cotton, and frequently in tank mixtures with knock-down herbicides, such as glyphosate. Under the system of HRAC classification it is a Group 14 (numeric), E (global) or G (Australian), since it acts by membrane disruption, through the inhibition of protoporphyrinogen oxidase. Carfentrazone is used on crops, fallows, forest plantations, industrial, horticultural and commercial areas.
