Carfentrazone-ethyl is a contact herbicide used to control broadleaf and sedge weeds in cereals.  Carfentrazone is applied as a foliar spray and is absorbed through the leaves.  Translocation after absorption is limited.  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.   Some of the broad-leaved weeds, controlled post-emergance, by carfentrazone-ethyl include Galium aparine, Abutilon theophrasti, Ipomoea ederacea  var.  hederacea, Chenopodium  album and several mustard species.  Crops for which carfentrazone-ethyl is approved for all edible and non-edible crops, including potatoes, barley, durum wheat, oats, triticale and wheat.
