What Is Sulfentrazone?

Sulfentrazone (Chemical Name: N-{2,4-Dichloro-5-[4-(difluoromethyl)-3-methyl-5-oxo-4,5-dihydro-1H-1,2,4-triazol-1-yl]phenyl}methanesulfonamide) s an aryl triazolinone herbicide used for pre-emergent and post-emergent control of certain broadleaf weeds, grasses and sedges. Isoxaben was registered by and manufactured by FMC Professional Solutions in 1997.

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 is used to remove tall fescue and sedges from warm season turfgrasses and Kentucky bluegrass.

How Does Sulfentrazone Work?

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.
