Customer Reviews for Tenacity Herbicide

We have tried everything to rid of crabgrass, without killing the lawn...or our neighbors' dogs. Nothing really did the trick. Out of sheer desperation, we tried Tenacity, It works like a charm! Just one teaspoon in 2 gallons of water.

Easy to mix, the directions on the bottles are pretty clear. The dye washes off with water so don't be alarmed if you get it everywhere. At first I didn't think it was going to work but after about a week all my crabgrass turned white, so be patient. Overall I satisfied with the results.

This decisively killed weeds that other herbicides I've tried wouldn't touch. I wish I had bought it long ago.

Followed directions and it didn't work. It killed some grass but not the creeping Charlie.

Just put down the second application about ten days ago. It worked Great killing crabgrass turning it white. Other weeds not so much. Looks like it had no effect at all on nutsedge and less then desired effect on carpet weed. I have had Poa Annua so I'm hoping it works to stop that next year. Had been using another product that worked well on it...

Great product! Fast shipping! Reasonable price! No more Creeping Charlie, Crabgrass or Clover! (the dastardly 3 C's) If I could change one thing it would be a larger surfactant, as there is not enough to finish the job with the other 2 chemicals. I will be back, and recommend to friends and family. Thanks! :)

Love Tenacity but 1st time buying from this company. Wish you would include instructions on how to use the bottles. Appears they have premeasured areas, but couldn't figure out how to make them work. As expected, all the weeds in my yard started dying within a week. Will reapply within the recommended 2-3 week timeframe so should have a beautiful lawn by mid spring. Definitely recommend Tenacity!! 4stars because of the bottles, not the product.

This is my third season using Tenacity. Tenacity has done a good job eliminating most weeds in my lawn. It may have reduced POA triv and annua. But I spot spray that stuff with glyphosate, so I don't know how much of the reduction is due to Tenacity. Still nice to see it turn white. Highly recommend Tenacity if you are looking to step up your lawn game

Followed directions, maybe just a little heavy handed, be patient it takes about 2 to 3 weeks. You will see it start to work, weeds start to turn white, some sections of my yard had so many weeds it looked like it snowed. So happy the dandelions and clover are gone. Looking forward to great looking lawn this year.

I purchased the tenacity with the recommended products from this site. I now have white patches on my lawn. It took two applications and still there were parts of my lawn that I had to de-weed by hand. I'm not sure of white my next step will be in that as I stare at the white patches, I truly don't know what else to do. If anyone has any suggestions, please don't hesitate to share it here. My lawn has white patches, dead patches, and patches of compost and new seeds that I put down. I'm not a happy gardener right now. :(

  Expert response:
We are sorry to hear your experience was unsatistory. Per the product label Yellowing or whitening of the turf after a broadcast application of Tenacity Herbicide is caused by the loss of chlorophyll and is normal. 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.

I used this system and have had 0 results. I will say I have not done a second application yet...but first application has shown 0 results on the crabgrass I sprayed. Very disappointed!

  Expert response:
Tenacity Herbicide when mixed with a non ionic surfactant will control crabgrass up to the 4 tiller leaf state only and is best applied when it is young and just emerges for best control and may require repeat treatments. For more mature crabgrass it would not control it at all so timing is key.

It works to certain extent, but not really worth the price.

I received my order faster than expected. FYI, I was expecting Tenacity to turn my yard white, it did not. So in a couple weeks, I'm broadcasting that stuff over my extremely weedy lawn. Wish me luck.

I put this down mixing it on the heavy side of the directions. Been over two weeks no change. Still have weeds.

Easy to use and works great. Have had a crab grass issue for years and could find nothing to kill it. You can see is starting to die in about 5 days. Hope it works as well in the spring as a pre emergent.

I ordered the Tenacity Herbicide Kit to kill the crabgrass that is taking over my centipede lawn. I have used atrazine with some success before, but I can't apply it during the Florida summer without injuring the lawn. I followed the directions and applied it after 6 pm when the temperature was in the low 80s. Now, a week later, the crabgrass is already white and the lawn isn't affected at all. I'm very happy with the results.

I've had very good results controlling creeping bentgrass in my TTTF lawn with Tenacity. The new container with the measuring system is much better than the old syringe. It's way easier getting the product into the sprayer without making a mess.

I found this size to fir my needs of spraying lawns. Its handier than the large jugs I use for fields. I use a 12ft boom sprayer and set the pump for 20psi and travel 5mph to get me a gal per 1000 sq ft. Calibrate your tips to get this and you can't fail. These containers measure it out for you. So once your sprayer is set with the tips you use and surfactant is added go to it. Can't be any easier. I noticed the water grass (crab grass) turning in 3 days.

Killed a few weeds. Burned my grass. I was told to use Weed and Feed.

The kit works fine for a small job. Through reading reviews I found out what my 3 main problems are, bentgrass, nimblewell and crabgrass. I literally had to spray my entire 7,000 square foot yard with a 2 gallon sprayer. Just completed my second application. Planning to do a third application in another 2 weeks then power rake the dead areas and aerate the entire yard before overseeding the yard. First off this is not a fast acting herbicide. After 2 weeks I see it killing more nimble weed and crab grass than the bent grass. It's set back but not dead yet. I wish I would have started 2 weeks earlier, but hopefully in another 2 weeks I see a good kill.

This product is excellent for killing crabgrass and weeds at their roots. Crabgrass was starting to take over my front and backyard, I stumbled across a video on YouTube. The guy was using a product called tenacity he gave instructions on how to use it properly and it works great!!! I'm going into the almost 3rd week of it and they're starting to turn white and die, it's very easy to use and works really well!!!!

Took a couple of weeks, but killed my nutsedge. It should have gone down in to the roots also. We will see if I have it next year or not.

The weeds were taking over, especially crabgrass, bent grass, dandelions, ect. Other weed killers did'nt work as this product. Easy to mix and use. You just have to be patient before the results are noticeable.
