Bentgrass invaded 1.5 acres
By Nancy on 11/19/2016
Amazing product. Wish had known after new seeding of 5000 sq ft in summer after pool install. Summer grass planting - Big mistake - was overrun with barnyard grass - good thing I love to weed = 6 hours a day for days and days. I knew I had bent grass, too - was invaded by neighbors - 'course easy to blame them (smile). Now am conquering bent grass and spray 2 feet into neighbor's yards on either side as a buffer. Lovin' the results. Happy to pay the price. thanks so much. Ohio

2nd REVIEW OF TENACITY
By Ab on 08/25/2017
I think the fact that I came back and bought more speaks volumes of what I think of Tenacity. Works on nimblewill, but also works great on just about all weeds. USE AS DIRECTED. A little goes a LONG WAY! Thanks for being helpful Tenacity! 10*. Note: Do use in tandem with Non-Ionic Surfactant for Herbicides.

Kills crabgrass as promised
By Billy on 08/27/2017
Applied tenacity as directed with the addition of Astrazine and Surfactant on centipede grass. In about a week you could tell something was happening, and in few more days the crabgrass turned white, the death sentence has been delivered. I plan on applying a 2nd application in 2 to 3 weeks after the initial application. Tenacity is the only herbicide you can safely apply on centipede grass and kill crabgrass.

Finally success
By Gb on 04/20/2018
After struggling for a year with weeds in my buffalo grass I found something that works and doesn't harm my grass. It is not an overnight process but the weeds are slowly turning white. I sprayed and waited a week to spray a second time. Then I sat back and waited. Love this stuff.

Tenacity over-hyped
By Walter on 08/17/2019
Seen some you-tube presentations on this and decided to give it a try. I used for spot-treatment and my observations: - takes at least a week to see if it's working - it's marginal when it comes to taking out mature crabgrass - For the cost/hype, I had expected it to be able to handle more weed varieties.....which it did not. There are other similar products that I expect to try once I use up this bottle

Jury Is Still Out
By Dennis on 08/30/2019
Sprayed as directed and added another product to make sure that is stayed on the weeds. Here it is almost 2 weeks now and still not much change as I would have expected. Especially, given the cost of this product. Wanted to get away from that deadly RoundUp garbage product. At least that made the weeds dry up and disappear.

Tenacity
By Jeremy on 08/30/2019
I have a centipede yard, which I had to resod this year due to spraying with some Home Depot herbicide... Expensive and back breaking experience. I have a bit of crabgrass and nutsedge coming up. The Tenacity turned it white and it is dying. I think I might have to apply once more to totally kill it. It works well and the centipede looks great! Didn't effect it at all. There is one weed the Tenacity didn't kill so I will have to treat with something else.

Not effective
By Ramesh on 05/11/2020
Bought Tenacity a couple of weeks ago and was excited to try it out based on the reviews. Unfortunately it was a huge disappointment. Added surfactant and blue dye so thatI could put it exactly in the right spots. Unfortunately, the product did not work as advertised. I still have weeds. Heck, it couldn't even kill the dandelions leave alone crabgrass. Very disappointed. In fact, I bought Moss Out and that didn't work either.

Bentgrass on the run
By Greg on 06/13/2020
Noticed a new invasive grass in my yard. IDed by searching invasive grasses on the web. Called Creeping Bentgrass, it will take over your yard if you let it. An old article from the Chicago Tribune said Tenacity is the only selective herbicide that will kill it. One must do 2-3 applications. I have done 3 and most of this bentgrass is dead. Tenacity is expensive but so far, worth it. It saved me from using Round Up and killing all the grass. P.S. do not get any of this on other plants. I had a little spillage near a couple of bushes and it killed a part of each bush.

Not working for me...
By Jeff on 07/03/2020
I'm not sure how this product gets such great reviews but it is certainly not working for me. I have mixed it carefully, used the recommended surfactant, and applied as directed. No type of weed has been killed off yet. I am on my fifth (yes, fifth) application with Tenacity, waiting two weeks between. It seems to slow them down but never kill them off. The grassy weeds, like nutsedge and crabgrass, do turn white but then come back. The broadleaf types, like wild violet and plantain, have their edges turn brown but never die off. For an expensive, professional product, I am very disappointed.

Great product
By Rc on 09/06/2020
Fantastic as a pre emergent when seeding; this has eradicated a significant crabgrass problem in my lawn and provided good poa annua suppression. A little goes a long way so spend some time reading the label. I had complete whitening of my fescue upon first use but this has reduced with each subsequent application.

It Works Great - Just Follow the Directions
By Vincent on 09/11/2020
This is an effective and easily-applied herbicide that will kill even established crabgrass, the reason for my purchase. Within several days of application per the easy instructions - I also added a surfactant and an agricultural dye to the solution - the crabgrass blades started turning white, the indication that the weed is dying. I chose to pull out the dead and dying weeds, a chore which is made easier by the Tenacity because the roots loosen - before spot re-seeding approximately seven days after the first and only application. Be forewarned: even if you're careful when spraying the herbicide, there will still be discoloration of the immediate surrounding grass.

50/50 Results
By The on 09/19/2020
Heard a lot about Tenacity. Figured I gice it a try as I have a lot of crabgrass. It only attacked about 25% of my lawn. It may need a second application. Along the way I studied that a healthy soil attacks or prevents weeds and grows good grass. I opted not for a second application b/c the crabgrass is soon to die any how. Instead of wasting chemical I decided to patch and overseed and focus on healthy soil and good watering practices.

Salvation
By Justin on 09/29/2020
After a decade of fighting crabgrass, from big-box-store granular pre-emergents, to the unending toil of manual removal of mature physical crabgrass plants with a weed removal tool....when i tried tenacity this year as a post-emergent for very well established crabgrass plants, I cried tears of joy for how effective it worked. I wish I could have all the time back I wasted over many years...had I only known about Tenacity.

Disappointed...Nothing has died yet
By G. on 10/23/2020
Fantastic Product
By Andrew on 05/21/2021
Bought a new home in January and discovered that, much like the inside of the home, the previous owners did little to care for the yard and landscaping. Come Spring, we discovered that the lawn was full of weeds. I've applied one application of Tenacity and most of the weeds are dead or dying. Only a few remain, but I would attribute that to the volume of weeds and my having never sprayed a lawn before. Will be following up with some spot treatment, but am thrilled with how the lawn is looking.
