Nutsedge destroyer!
By Mark on 07/20/2022
I have only used this once on a large patch of nutsedge in my lawn, in my neighbor's flower bed, and in another neighbor's lawn all in the same day. It has been 6 weeks now and we are completely nutsedge free. Me and my neighbors are so pleased. It was a little slow to show it was working, but don't let that fool you! The kill rate with this stuff was 100% with just one application. I'm shocked that 6 weeks later there is still zero nutsedge in my lawn. I mean one of it came back. I was expecting at least some nutsedge to pop up that hadn't been sprayed but, no there is nothing. I don't have enough good things to say about this product. It simply works. Location: Austin TX Grass type: Bermuda.
Still waiting to see...
By Rhoda on 03/24/2023
I bought Certainty to take care of the poa annua that was trying to take over my yard. I have bermuda grass and after testing the soil temperature to make sure the bermuda was still dormant, I sprayed my lawn and 5 feet into my neighbor's yard. Now it's wait and see since getting rid of poa annua is not an overnight process. I just want to prevent it from going to seed.

Not quite what I expected
By Rob on 07/22/2023
First, I want to say that I really like dealing with DoMyOwn, but this product has been a letdown. I was in a chat about Poa in my lawn, and bought a pre emergent for use this fall. I do admit that the person I was chatting with said that using pre emergent was The Best way to deal with it. I asked about anything else that could be done, and they said there is this product call Certainty that can be used Post Emergent, so I bought some. It's about $129 for 1 1/2 ounces of powder. I mixed it according to directions and sprayed it on a couple test patches. Not much happened with the first application for about 10 days, so I reapplied. I think I would have been better off with Roundup. It totally kills Poa, but no one can tell me if I can now reseed these areas or if they are barren for six months. So I have horrible dead patches in the lawn, still have 95% of the Certainty left, and am left wondering if anyone should ever use this on a residential lawn......it's a big waste of money. Use Pre Emergent in the fall!
Expert response:
You may notice signs of the poa dying (discoloration-yellowing or browning) within 2-3 weeks after you have applied Certainty but it is normal not to see anything for at least a month. Per the product label, you can make an additional application 4 or more weeks after the initial application as needed. According to the product label, you should wait at least 3 weeks before re-seeding or over-seeding after application.
Excellent Herbicide/Surfactant

Certainty helped clear up a massive infestation of Yellow Sedge in my Bermudagrass. The surfactant obviously helped with penetration. However, I didn't find the blue indicator dye particularly useful in my residential application because I couldn't see it (medium concentration) and it makes a mess.
Johnson grass
By Randy on 10/27/2023
I used certainty on what I would call Johnson grass broad leaf grass that growers a stem of seeds.the stuff was expensive so I put 3 little scoops about half a teaspoon in 2 gallon of water in a back pack sprayer about 3 weeks ago in Oct. Spayed where ever I saw it heavy in some areasnd had just enough to cover all the areas,all dead! I'll have to spray again next year when I see before it seeds,but I have several years of product left.sprayed it on a burmuda grass called celebration no damage.
