    used with speed Zone product

    By Glenn on 04/23/2021

    The cool weather and two-three weeks of leave alone time cultivated a good batch of grass in the stead of weeds, I'm very happy with the results

    Best yet.

    By Mike on 04/04/2022

    I struggled recently with growing weeds taking over my front lawn. Living in South Carolina, deer walk thru our yards at night and leave dropping containing seeds from the weeds i've come to find in my yard. Three videos later from my research lead me to be most interestes in this product. Lawn care professionals in my area use this on the golf courses and neighboring property lines.

    Worked great...so far. Dgrass vanished after 2 applications BUT also took out some of the lawn. Apparently some grasses are effected.

    Slow, but amazing results

    By Wallace on 06/03/2022

    This herbicide takes a week or two to work, but works as advertised. I used this to spot treat crabgrass and dandelions in the spring. In a little over a week they have turned bright white without affecting the surrounding grass. Although not labeled, I also tried it on broadleaf plantain in newly seeded areas and it worked.

    I've always used tenacity on my bermuda grass, especially when spot treating for weeds. Haven't had any issues.

    Tenacity works

    By Gary on 04/19/2024

    Well fellas I had the great idea to skip pre emerge to see if I really needed it. Unfortunately the clover and crabgrass loved this. It grew everywhere. Saw this product on you tube video. Bought the surfactant and die also. It killed all the weeds with a vengeance. Only thing you have to be patient. 1st week the weeds just laughed. 2nd week the weeds began looking like it got their attention. By third week they turned white and were dead. Now Bermuda grass coming up and weeds are no longer a problem.

    Works

    By Dan on 08/14/2024

    The only thing I have used that kills actively growing crabgrass and I have tried almost everything on the market. I bought this house in the woods about 4 years ago. I have no illusions of having a golf course type lawn but I am not growing weeds and Tenacity is another item to use in my battle against weeds.

    Tenacity is a Winner!

    By Ernie on 08/16/2024

    I bought this product because my new development’s HOA landscaping crew said I had to wait 2-3 years for all the crab grass and other non-desirable weeds could not be touched with weed killer because it will kill the new seed growth. BS! This worked awesome! Pics would show you white blades of witch grass and grabgrass dying, along with my new grass seed right next to them! Totally worth every penny!

    Crabgrass control

    By Bill on 08/01/2025

    This product works as advertised. The crabgrass turns white in 7-10 days. Amazing to watch. Did not hurt my fescue grass at all. Very happy with results.

    Love it.

    By B on 07/22/2014

    Product appears to be a little pricy; however, the dosage amount needed makes it cheaper than products from the box stores and this product works better. The only draw back on this product is you have to be patient to start seeing results which I've experienced is about a week.

    Good cool season product

    By Jeff on 04/22/2015

    Verified Purchase

    This product has done a great job of knocking down some very tough weeds in my Kentucky Bluegrass turf. Waiting to see how the residual controls as a pre-emergent as the weather warms up.

    Tenacity

    By Don on 12/03/2015

    Worked beautifully to remove all forms of weed grass including bent grass and poa trivialis. Now I only have Rye grass left and the lawn is so beautiful people have asked if I just laid new turf! Would recommend this hands down, just be patient, it doesn't kill overnight and you do need to remove the dead weed grasses afterwards. Best to rake out the dead weed grasses once it has thoroughly killed them off before reseeding. The syringe is the only problem with the product, it binds up immediately. Toss it and measure out the liquid with a measuring spoon instead.

    Works but be aware of results

    By Rick on 04/20/2016

    I've been using this on my maintenance jobs and it seems to be taking out Bent and other weed grasses. But be aware that you might kill more than you expected. I found that some of my lawns were over half bent grass and now I have some pretty damaged looking lawns. May have to reseed. It turns the dying plants a brilliant white color so may be a little shocking to customers.

    Tenacity Kills Nimblewill Dead!

    By Joe on 08/18/2016

    Worked as advertised. 10 to 14 days after 1st application my Nimblewill turned white (kinda neat as you can see it working from across the yard). I have applied a 2nd application to make sure I got it all as this weed grass takes over, growing densely in areas where its gotten a foothold in my lawn. I used a surfactant (Hi-Yield Spreader Sticker) per label instructions. The syringe that came with the product is great. You don't want to waste a drop of this stuff. It's very effective but not cheap.

    FINALLY a product that will kill Nimblewill, not Bluegrass

    By Lk on 09/04/2016

    Applied the product as directed to all stands of nimblewill and broadleaf grasses, and all turned white in about 8-10 days. They have continued to die and are slowly turning brown. Easy to mix and apply. Very satisfied, great product!

    Nimblewill Killer

    By Roger on 09/17/2016

    Don't let nimblewill take over! In home turf it spreads in outgrowing circles and the effect is not good. Purdue Ag Agent advised dead kill or pick it out by hand - right! Tenacity has solved our problem. It took most of two seasons as I was very cautious not to over use. Advice about spraying a second time is excellent as you will miss some. Reaction time is longer than most and using a spreader is wise. Watch closely for regrowth and be careful handling. I'm a chem major; this is a great product but deserves care and respect.

    Love Love Love this product

    By Barbara on 05/22/2017

    I had large patches of bent grass. Used this product. It took awhile to work. Transitioning from light green to white. Put on in mid April. Now the blue grass is growing thru the remains of bent grass. I will use again this fall if needed. Thank goodness for this amazing product.

    Awesome

    By Dan on 06/06/2017

    I neighbor recommended this for my Kentucky bluegrass lawn which have several different annual blue grasses and some other fat leafed grasses in it. I have spot applied tenacity about 4 or 5 times and almost all of my annual grass has been eliminated. It is even working on the other weeds as well.

    Tenacity Herbicide from DoMyOwn

    By Steve on 06/07/2017

    With neighbors whom do not treat their yards, their nibblewill grass was creaping into my yard. After spraying, one week later the grass is white and dying. KY 31 is not affected. Good product.

    Tenacity

    By Lonnie on 06/26/2017

    Great product! Purchased it mainly to combat nimblewill and it honestly did a bang up job for me. It works well on other listed weeds as well. It's a slow acting product but sure does the job, especially with two recommended treatments.

    Bye bye crabgrass

    By Pat on 07/03/2017

    So just planted Kentucky blue it is up about 1 inch and the crabgrass just took over. So read other posts, thanks for them. Bought the 8 oz offer and mixed 8 oz to 30 gal with surfactant . Two days later the large 10 inch tall crabgrass is turning very light green HA HA HA crabgrass once it finally croaks probably Friday will pull out roots and overseed to patch bald spots. Treated 10000 sqft with pullbehind tank sprayer with 3head boom and hand wand for corner teeatment. This stuff really works

    Tenacity is 10* all the way

    By Ab on 08/02/2017

    Some of my nimblewill came back, but could be seed and it really beat it back. Works great on broadleaf too. This stuff costs a little bit, but is worth every penny. USE AS DIRECTED! Surprises how little it uses. Do use in tandem with Non-Ionic Surfactant for Herbicides.
