Certainty Herbicide
By Al on 05/09/2017
Used as directed for nut sedges, first attempt very poor results. After three weeks, will reapply and will post update. The very thick nut sedge I had to use Round Up because it has taken over that area and was afraid to wait anymore for Certainty to work. Three stars and pending...

Certainty Didn't Kill
By Terrypowell on 06/10/2025
Applied as directed. In about a week my lawn started turning yellow and within 2 weeks I had dead patches everywhere. Was gonna kill and till anyway if this didn't work. Just wanna reiterate that you probably would be better off and test a small area first. I took it for granted and that was stupid of me to assume.
