Rated 5.0 out of 5.0 by Luvcats Really kills poa annua!!!
After searching on line and finding all information which basically said Poa Annua cannot be controlled by homeowners, only professionals. I tried this product, and lo an behold it has killed the invasive Poa annua in my Kentucky bluegrass lawn. Thank you Ortho, but how about a larger size?

Rated 1.0 out of 5.0 by tap50 Killed Lawn in several places....
Used this product to knock my nutsedge back in several places, but it has killed the centipede in three places of main application. The only thing left is dead grass and bare dirt. Doesn't seem to hurt the bermuda that volunteers up though. Very disappointed because I was using another product that DIDN't kill my grass. May have to re-sod the three areas. Will be contacting customer service for help.

Rated 5.0 out of 5.0 by abcmommy This KILLED my nutsedge
In July, Day 1... At 6pm I sprayed the patches of nutsedge all over my front and backyard during 80 degree weather. 24 hours later, the previously green nutsedge was turning yellow/brown. On Day 3, it rained for 30 minutes, hopefully pushing the poison down into the dirt to kill the bulbs of the nutsedge, and there was more wilting and dying. On Day 5 before mowing the lawn, they were wilting and brown even more. AND this was all during days of 90 degree summer heat.... my grass was hardly damaged; there were two small patches probably where I sprayed a bit too much. On Day 7, after mowing you can barely see the nutsedge that is left.
Now to be honest, I had the same results last year, but some still grew back. I guess it'll take a few years to get rid of it all.

Rated 5.0 out of 5.0 by Tom62 Ortho Nutsedge Killer works great
I have had a huge Nutsedge problem in my yard for years - my lawn always looks great in the spring but as soon as the St. Louis heat starts up so did the Nutsedge. Over the years I have tried everything and nothing seemed to work until I found Ortho Nutsedge Killer. This product worked perfectly on my lawn and did not kill the regular grass - (I have a mixture of Tall Fescue / Bluegrass / Zoysia). I have a very large yard and it took a few bottles to get the Nutsedge under control and then a few spot applications as some new areas started to spring up but my yard has never been this free of Nutsedge in over 20 years that I have lived here. I always spray the Nutsedge a few days after I mow, because it is easy to see as it grows so much faster than the regular grass. I then can see it turn brown and die and by the next time I mow it doesn't come back. Hopefully I won't have any new Nutsedge next year but if I do, I know how to get rid of it now. Thank You Ortho for making a product that really works.

Rated 5.0 out of 5.0 by Austin4128 Works 100% better than the other products; wish they still had the concetrate
I tried the concentrate 'Image' and bought two large containers with a sprayer. Diluted according to directions and nothing. Never worked. The Nutsedge is still there. Ortho ready to use is much more effective within 24 hours you see results. They use to have it in a concentrate and now I guess it is no longer available unless you want to hook it up to your hose. I have a large yard with a pool and do not want to hook up with my hose and trail around my yard trying to get to areas that the challenging to maneuver around. Purchasing the 24 oz I have used about 8 of them so far and this is getting expensive. Come on Ortho! Produce a concentrate that can be diluted for more convenient larger yards!
This product works.

Rated 5.0 out of 5.0 by ralphmouth Overall satisfied
I like this product but must use caution as it will "kill" the grass if it is left to long on the sprayed area (I use the hose/attached bottle).
I also used the Ortho dial-a-spray bottle for diluting other Ortho products and was wondering what the attached bottle orifice is as I'd like to put the setting on half on that of the attach bottle.

Rated 3.0 out of 5.0 by tcool6 Killed nutsedge but browned grass
I have a nutsedge problem in my back yard in north central Florida. I applied it to St Augustinr grass which it says is safe. It saw great results within 48 hours and noticed that the nutsedge was dying. However, my grass has turned yellow and looks really bad in the days since. I know the bottle says that stressed lawns may discolor but I'm a little worried that I've killed my lawn. I'll give this better reviews if my lawn comes back, just be cautious with this product and try it on a small patch first.

Rated 1.0 out of 5.0 by Qneo Killed my lawn , nutsedge still growing
Used to the direction, has browned or killed my tall fescue, nutsedge still growing. Do not use, use a spot treatment, not a broadcast spray. Just keeps getting worse, after 2 weeks of almost constant rain it just kills more lawn and nutsedge is still present.
