Nutgrass herbicide


Do you prefer Sedgehammer or Dismiss when attacking Nutgrass? I have had more success with Dismiss but was told it sends out runners when used. Sedgehammer seems to work but only after a 3 or 4 week wait. - Harold -

    Harold, here’s a link to an article about nutsedge, which may be helpful: http://www.johnson.ksu.edu/p.aspx?tabid=516 Be sure to read the labels and apply as directed.

    Both are good but I would go with the active ingredient in the Dismiss product. That is a commercial herbicide so it is not available to a home owner. But sulfentrazone is available in some over the counter products. Dennis Johnson County extension

    I don’t care how long something takes, as long as it kills the nutgrass for good. I think some of the best herbicides are the ones that require the most patience from us. They thoroughly kill the roots and nutlets, and the topgrowth is the last part of the plant to show symptoms. By that time, it’s a zombie.
