Carfentrazone

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. It is also an effective selective herbicide and causes death by targeting plant cells.

Solutions Pest & Lawn has in stock quality herbicides that contain Carfentrazone. On this page you can learn some interesting facts about carfentrazone, how it works, its benefits as well as shop our recommended products that are Carfentrazone-based.

What is Carfentrazone?

Carfentrazone-ethyl 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. 

Carfentrazone is absorbed through the leaves of the targeted plant.  Translocation of the active ingredient after absorption is limited, meaning the herbicide moves very little from the site applied to another part of the plant. 

Carfentrazone is available at a number of different concentration ratios and in a variety of formulations such as micro-emulsion, emulsifiable concentrate, water dispersible granule, and a water-soluble granule.

Carfentrazone is often used in combination with a number of different herbicides active ingredients. For example, Carfentrazone is also often used in combination with Metsulfuron for agricultural herbicides to control broadleaf weeds in both winter and spring grains and barley.

How Does Carfentrazone Work?

Mode of Action

The mode of action of Carfentrazone is the disruption of plant membranes by halting the action of a necessary part of plant development known as protoporphyrinogen oxidase, resulting in the death of cells.

Benefits of Carfentrazone

There are several characteristics that make Carfentrazone-based products stand out from the more traditional broadleaf herbicides. For example, it works quickly: 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 competitor herbicides, which cause a gradual “melting away” of weeds over a longer time.

Carfentrazone is best used when dealing with invasive weeds or vegetation on agricultural, commercial or residential sites. Check the label for a full list of approved areas.

Drawbacks of Carfentrazone

Carfentrazone needs to be mixed with a surfactant for best results. There are some common broadleaf weeds that Carfentrazone is ineffective against. You will need to check the label to see which weeds work best against weed.

Do not use Carfentrazone for weeds that are not specifically labeled to be controlled by the active ingredient.

Is Carfentrazone Safe?

Carfentrazone is safe to apply when applied according to label directions. Make sure to wear the proper safety gear and equipment when handling this product, you will have nothing to worry about when applying it to your lawns.

What To Expect

An application of Carfentrazone begins to harm the plant as soon as the target weeds are contacted by the chemical and only takes approximately 72 hours to kill off most unwanted weeds if caught in early stages 1-4 inches in height. Repeat applications may be necessary if a weed is very persistent or well established.
