Turfgrass Weed Control Database

The Turfgrass Weed Control Database contains the same information and pictures included in the Miscellaneous Publication MP-521. The weeds are arranged alphabetically by scientific name because common names vary and thus be inaccurate.

Annual Sedge, Cyperus compressus
Cyperus compressus
Monument (trifloxysulfuron), Certainty (sulfosulfuron) and Dismiss South (sulfentrazone + imazethapyr) provide excellent annual sedge control. SedgeHammer+ (halosulfuron + surfactant) is a good sedge control choice for homeowners because it is effective on common sedges, comes in a small package with surfactant added, and is safe on all turfgrasses. Hi Yield Nutsedge control also contains halosulfuron. Ortho Nutsedge Killer for Lawns (0.05% sulfentrazone) is quick acting herbicide that is fairly effective on most sedges and safe on most lawn grasses. Sulfentrazone is fast acting and will cause leaf burn on sedges within two to three days. It is weaker on purple nutsedge compared to halosulfuron.
