Carfentrazone (also known fully as Carfentrazone-ethyl) is an active ingredient found in herbicides utilized to kill broadleaf weeds. It is a contact herbicide and applied as a foliar spray, with little translocation. It is also an effective selective herbicide and causes death by targeting plant cells.

Solutions Pest & Lawn has in stock a number of quality herbicides which contain carfentrazone. On this page you can learn some interesting facts about carfentrazone, it’s history and benefits as well as be able to shop our entire line of products that are carfentrazone-based.

What is Carfentrazone?

Carfentrazone-ethyl (C 15 H 14 N 3 Cl 2 O 3 F 3 ) is a contact herbicide primarily used in agricultural settings to control broadleaf and sedge weeds in various grains and crops.  Carfentrazone is applied as a foliar spray and is systemic. 

More specifically, carfentrazone is heterocyclic organic compound from the triazolone class of chemicals.The chemical is absorbed through the leaves of the targeted plant.  Translocation after absorption is limited. 

Carfentrazone-ethyl is available at a number of different percentages and in a variety of formulations such as micro-emulsion, emulsifiable concentrate, water dispersible granule and a water soluble granule. Carfentrazone-ethyl is often used in combination with a number of different herbicides. FMC Global Specialty Solutions sells carfentrazone-ethyl under the popular brand name QuickSilver, which is 21% g/l carfentrazone-ethyl in a Emulsifiable Concentrate and is marketed to eliminate silvery thread moss from turf. 

Carfentrazone-ethyl is also often used in combination with metsulfuron-methyl to control broad-leaved weeds in winter wheat, winter barley, winter oats, spring wheat, spring barley, spring oats, durum wheat and triticale.

How Does Carfrentrazone Work?

The mode of action of carfentrazone-ethyl is the disruption of membranes by inhibiting the action of protoporphyrinogen oxidase, causing cell death.

Carfentrazone is a non-selective herbicide 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-emergently 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.

There are several characteristics which makes carfentrazone based products stand out from the more traditional broadleaf herbicides. For example, it exhibits in relatively rapid fashion: you may see browning of weed foliage as soon as 1 to 2 days, and potentially a complete kill in about a week. This contrasts with most phenoxy herbicides, which cause a gradual “melting away” of weeds over a longer time.

Also, although formulated as an ester, this product reportedly exhibits low volatility. Nevertheless, it still is best suited to spring and fall applications because its activity is greatest at temperatures under 75°F.

Carfentrazone-ethyl is not carcinogenic, neurotoxic, mutagenic and is not a developmental or reproductive toxicant. Carfentrazone-ethyl breaks down rapidly in the environment.


While low levels of chemical residue may occur in surface and groundwater, risk concerns to non-target plants or animals are not expected. Carfentrazone-ethyl is considered to be practically non-toxic to birds on an acute and sub-acute basis. The chemical is moderately toxic to aquatic animals.


This herbicide should be stored in a cool, dry place and after any handling a thorough hand-washing is advised. As with any of the herbicides we carry, we recommend using protective equipment before applying. Gloves, protective glasses and long sleeve clothing should be a bare minimum level of protection.
