I have always used either Prosedge or Hi-yied to kill Nutgrass. I actually accidentally ordered this one, and was not pleased. It seemed to have no affect on the Nutgrass in my Bermuda/Rye lawn. This was twice the price, and no result.
Thank you for your feedback! We are sorry that you did not see the desired results from the Monterey Nutgrass Killer. This product does require the use of a surfactant for best results. You will also need to give the product about 14 days to start seeing results on the target weeds, and more mature nutsedge can require two applications 8 to 10 weeks apart. It is also possible that the weeds you are treating may not be yellow nutsedge, but a more difficult weed such as kyllinga which can be difficult to identify. Please feel free to reply to our email or give us a call at 866-581-7378 M-F 9a-5p EST to troubleshoot or if you have any other questions or concerns.
