Common NameCarfentrazone-Ethyl(F05038)
2D Structure
Description

Carfentrazone-ethyl is a contact herbicide used to control broadleaf and sedge weeds in cereals.  The mode of action of carfentrazone-ethyl is the disruption of membranes by inhibiting the action of protoporphyrinogen oxidase, causing cell death.  Carfentrazone is non-selective, and can be used for complete vegetation control, as well as as a desiccant and a defoliant in some crops.
