Tenacity Herbicide Kit

Tenacity yuck
By Cher on 09/17/2021
My entire yard turned white and or died from the tenacity application. I followed the directions perfectly, and watched tons of yard care videos on top of that. Very disappointed at the ugly and disastrous results. I did read that the grass that turned white might recover but it looks pretty dead to me. Oh well. I tried.

Does not work for my crap grass
By Andre on 09/26/2021
I bought the Tenacity Herbicide along with the Spreader Sticker and the Dye. Instructs are clear and with the included syringe it was easy to mix and spray with my Husqvarna 4-Gallon Backpack Sprayer. The first application did have no effect at all. Further applications killed some of the weeds, but did not get rid of the broad leaf grass. In fact, after all the grass turned white, the crab grass was the first to recover. After another application, I have spots where nothing but broad leaf grass remains. I am awarding 2 points because it kills some weed. But there are a lot of cheaper alternatives out there in the market. For the purpose that I bought this, it did not work at all.

I love what it's doing to my weeds
By Jose on 10/01/2021
Allocate lots of Preparation time. Effective.
By Zach on 11/13/2021
Potent, Handle with Care. Read ALL instructions in ADVANCE. Like medical prescriptions, 'how much to use' is buried very deep within instructions. I would like this information highlighted and easy to find. Wear protective and double-protective clothing. Beyond spot weeds, recommend a (power) battery operated sprayer. Your back will thank me. Results were positive for a home lawn of an acre. Will reapply selectively about 3 months after initial application. Unaffected weeds will be addressed with a different herbicide. Lawn unaffected. Be careful, be prepared, go for it. DMO-easy and helpful.

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.

Didn't work
By Craig on 04/22/2022
Fair
By Sherman on 04/25/2022
Followed instructions to the "T". Applied to clover as described. Nothing happened. My St. Augustine grass turned colors but that's about it. I believe the clover called over its friends and had a party. The surfactant and dye worked but the Tenacity not so much.

Tenacity
By Cindy on 05/06/2022
Ordering and receiving the pkg was good as usual but after reading about it again so I would use it properly I found that a lot of the people who have purchased and used it are not happy with the results, wish I would have bought something else as it is expensive.

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.

Application
By James on 06/27/2022
I recently applied tenacity to my lawn after mixing the ingredients according to instructions. After several days I mowed my grass and under the top growth it has turned white. I am very nervous as to how this may turn out.

Works great!
By Pete on 08/26/2022
I loaded up a field king backpack sprayer with tenacity, surfactant, and dye as directed. You definitely need to die or you have no idea where you sprayed. One pass did a lot of damage to the crab grass, even pretty established plants, with no damage to the lawn. I'm very pleased with it.

Weeds that defy
By Daniel on 10/16/2022
Spent the $ sprayed the weeds, twice, and the clover just laughed and mocked me. After two applications the clover had leaves showing some damage from the application, but overall they just carried on spreading here there and everywhere. Very disappointed in the product!

Tenacity

What to expect
By Dave on 06/08/2023
First off, this stuff works. But it works like glyphosate works. My cool season lawn was becoming overrun by wild violet and some poa patches. The wild violet was out of control and extremely difficult to pull since there's a huge fat root below the scrawny leaves. You get the leaves and flowers, but the root stays. After a while I tried spot application with tenacity. The weather was mid-spring cool, daytime highs in the mid 60's. About 5 days after application everything that was touched by the product began to bleach, even the bluegrass and fescue in my lawn. It made the lawn look hideous. I had to resort to paint to hide the damage a bit. It did indeed kill the wild violet, but it also killed the grass. I tried lowering the application rates and in that case the violet and grass both bleached but neither of the two died. After a few weeks it looked like nothing had been done. So I'm at my wits end with tenacity. It's expensive and so far has done nothing but what I could've accomplished with glyphosate. From what I've uncovered in research it appears that even if tenacity does work killing weeds, it will at a minimum bleach your grass for a few weeks, which hopefully will regrow. That's how it's supposed to work. I didn't expect that. So if you apply this expect your lawn to look hideous for a few weeks but hopefully able to recover minus the weeds.

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.

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.

Tenacity works
By James on 09/01/2016
This product has gone beyond my expactions. I like the idea the weeds turn white so you can see what has been missed.many neighbors has seen it work and ask about it. They like the idea it does not harm their lawn and see the results.I like the fact you can put down new seed with no harm to the seed.

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.
