Does Quinclorac Kill Nutsedge?

Quinclorac has been shown to kill and control yellow nutsedge. However, it is still not demonstrated to kill purple nutsedge. Other products, including Sedgehammer, and herbicide sprays that mix Sulfentrazone with Quinclorac are among the most effective for killing nutsedge.

Is Quinclorac the Best Product for Killing Nutsedge?

Although Quinclorac will kill yellow nutsedge, it is not the most effective sedge killer. There are several other herbicides on the market that kill all types of sedge grasses and are gentle on turf grass.

  • Quinclorac is only effective at killing yellow nutsedge. It won’t kill purple nutsedge.
  • Multiple applications of Quinclorac may be necessary to completely kill sedge.
  • Alternative products are more effective than Quinclorac at killing and preventing nutsedge.

If you are looking for a product specifically designed to control nutsedge, Quinclorac is not the best option. When searching for a Quinclorac product that also kills all types of sedge, check to see if Sulfentrazone is listed on the product label. Sulfentrazone is a nutsedge killer that boosts the sedge control properties of Quinclorac. It is included in this weed spray.
