Customer Reviews for Tenacity Herbicide

This product did not kill the dandelions in my lawn. I'm reasonably sure I applied it correctly according to the directions.

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.

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

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.

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 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.

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!

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

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.

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.

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.

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!

1 Application has turned most of the yard white. Killing weeds slowly, not so good on crabgrass. Delvery and ordering with Do my own is always great.

  Expert response:
We apologize results were not as expected Yellowing or whitening of the turf after a broadcast application of Tenacity Herbicide is caused by the loss of chlorophyll. The product label states, "Tenacity may cause temporary whitening of turfgrass foliage. In general, symptoms appear five to seven days after application and last for several weeks. A repeat application to the same site causes less whitening of the plant tissue." Per the label it is not recommended to broadcast Tenacity as a post emergent application due to this and it is best applied as a spot treatment directly to target unless you are doing a complete turf renovation or reseed the lawn.

I sprayed Tenacity according to directions and I still have dandelions. It didn't seem to phase them.

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.

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.

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.

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.

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.

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.

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.

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!

This stuff really knocks out crabgrass. Works on other weeds too.

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.

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.
