What is Sulfentrazone?

Sulfentrazone is a herbicide used for pre-emergent and post-emergent control of broadleaf weeds, grasses and sedges. It also works selectively, targeting only problem weeds while sparing desirable vegetation.

Sulfentrazone has the ability to eliminate annual and perennial sedges as well as cool-season grasses(Poa annua, Poa trivialis, tall fescue). It also controls broadleaf weeds that are in established, warm-season, perennial grasses including bermudagrass, St. Augustinegrass and zoysiagrass, centipede, and kikuyugrass. Sulfentrazone has shown effectiveness against tall fescue and sedges from warm-season turfgrasses and Kentucky bluegrass.

How Does Sulfentrazone Work?

Mode of Action

Sulfentrazone control weeds through its mode of action by inhibiting photosynthesis in plants. Sulfentrazone disrupts membranes and inhibits photosynthesis in plants by a process referred to as PPO inhibition. Sulfentrazone is received in the plants through the roots of the plants.

As the plants come out of the soil, they die after exposure to light. It also works on foliar contact causing rapid desiccation.

Benefits of Sulfentrazone

Sulfentrazone is versatile in that it can be used as a pre-emergent or for post-emergent control. Sulfentrazone does an excellent job on both warm-season and cool-season grasses and has a broad list of weeds that it can control. It is also known to have a residual of up to 60 days so you won't have to reapply often.

Use Sulfentrazone to control weeds in established warm and cool-season turf, trees and shrubs and other ornamentals.

Drawbacks of Sulfentrazone

Sulfentrazone is not known to be effective in controlling grassy weeds and is mainly used for broadleaf weed control and sedges. It also has a limited residual effect on spurge and bittercress weeds.

Is Sulfentrazone Safe?

Sulfentrazone is safe to use when applied according to label directions. 

It is recommended that when handling Sulfentrazone (or any of the other chemicals we carry) to use proper personal protective equipment (PPE) before handling or applying (Gloves, protective eyewear, long-sleeved clothing). Please refer to the label for proper safety instructions.

What To Expect

Apply Sulfentrazone products as a broadcast or spot treatments to areas where you have problem weeds. You should see visible signs of weeds dying within 1 to 3 weeks depending on the weed. For more stubborn weeds, reapplication may be necessary.
