All the annoying plants in my yard are now dead. Only grass remains.

Order delivered without hitch. Reviewed FAQ and had answers to all questions. First application was ranging shot to make sure the grass didn't die and weeds did. After two weeks the white weeds are proof this is what the lawn needs. Ready to give the entire lawn a dose. First time using indicator dye--works great! Will use that in all future sprays!

Works good on crabgrass. Plus some other undesirable weeds.

Works exactly as expected/advertised. I'll probably buy a bigger set next time as I have a ton of yard. Seemed like I went through it fast but when I did the math it was totally what they said it would be.

I'm surrounded by crabgrass on 3 sides. It doesn't matter now thanks to Tenacity. Been using it 3 years now and plan to continue. I even got the added bonus of it working on yellow nutsedge as well. I can't imagine being without it again. Thank you Syngenta!!!

Great product, a little preparation-intensive, but works well on creeping charley, nimblewill, and yellow nutsedge!

Great product that is easy to work with. I used it as a post emergent first and began to see initial results on day 3. A lot of whitening visible by day 7. It is the only preemergent that can be used while seeding your lawn so a big plus for me since I over seeded all of the dead spots in my lawn that were overtaken by the weeds I sprayed.

This products takes some time to kill the plant but it does the job effectively... just don't anticipate an "instant kill" like some other products.

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.

This product worked as advertised. Definitely impressed and glad I purchased it for my tall fescue grass and herbicide control.

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.

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

Holy crabgrass killer.Didn't think it worked a day later they turned white and started to die off

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! :)

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 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.

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.

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.
