Customer Reviews for Tenacity Herbicide

I purchased tenacity and applied on my lawn. First application was done but about 6 hours after it rained. Waited a few days and applied again, a few days after the weed leaves started to turn yellow, but not died from the root, as a few week after they grow back again. Also, tenacity seems nit effective to some weeds at all. Not sure what to do, as I wanted to reseed shortly, but would like to get some space for the seed.

After planting a bag of Scotts ever grow grass seed my lawn grew an abundance or weeds including crabgrass. I applied Tenacity according to the directions. I applied a second mixture ten days later. My grass is now being allowed to grow and the crabgrass and other weeds are dead and all brown. This stuff is amazing.

I have wrestled with crabgrass in my yard for the eight years we've been here. This product wiped it out... mid summer with it establish and growing again. The bluegrass in invades every year was untouched. I can't wait to see the result next year as a PRE-emergent.

Tenacity works as promised, it take a little time but it works

Product does kill crab grasps but also kills other grasses around it as well. Must use extreme care when spraying if you just want to kill offending grasses.

When it comes to controlling established crabgrass, this is the only product I have found in 37 years of lawn maintenance that does the job right out of the gate. No damage to existing turf when used as directed.

My yard has been overtaken by various types of weeds. Tried all the commercial stuff (Weed-B-Gone. spectracide etc) that are available at Home Depot and none yielded any result. I used Tenacity and many of the weeds were dead in 2 weeks. It was especially effective on crab grass. I have this one very invasive species that looks slightly like Mary's grass (not quite). My backyard was covered with it. Tenacity only killed small areas of it. Some leaves turned white while the remaining are still green. I guess I will have to apply one more time. The application left a lot of bare spots, not because it killed the grass, but because there was so much weed. Still, I am happy that Tenacity did a lot better than the big name herbicides from Home Depot.

Been trying to get rid of yellow nutsedge out of my yard for years and I think I got it with Tenacity. I had tried many other herbicides and could not get rid of the nutsedge. I Highly recommend Tenacity. It will turn the nutsedge and any crabgrass white and it can look kind of bad during the killing phase but did not hurt my fescue grass.

I tried tenacity to see if it would kill my nutsedge. It worked! Very happy

I'm always skeptical about a new chemical, but Tenacity worked exactly as it claimed. Use it lightly and consider mixing in TurfMark so you can see it go down. It kills crabgrass in a few days without harming centipeed grass. I spot sprayed and 3 days later you could see the crabgrass starting to die.

Despite treating in spring with the blue fertilizer, I had a lot of crabgrass in my yard. I was hesitatnt to treat because of the heat, biut it was getting out of control. So I used for Tenacity for the first time with good results. At this time the crabgrass is all white, dying and the lawn is not affected.

I used Tenacity to remove bent grass from the backyard and some spots in the front yard. It worked great, the grass turned white and now it's dying.

This is the active ingredient to the three part ingredient recipe. It appears to be working, the crab grass turned blue immediately after spraying and then white after about a week after application and now appears to be turning brown and hopefully dying.

Did not expect any results. Be patient. Then check out the tips on quackgrass! Yep. Live in Indiana and it worked. Was going for nutsedge and poa annua, may need a couple more rounds.

I tried this product out after watching a silver cymbal vid on you tube. Four days later still no results. So I tried a second application wi more tenacity than required five days later it's starting to work.

Did a great job on my yard with crabgrass and clover. I will do a second application. The syringe worked very well to get an accurate amount per gallon.

I maintain about a half acre of turf and this was very effective on my young as well as established crabgrass. I used it with a nonionic surfactant as recommended to get it to adhere to the crabgrass. Within one week there were visible signs that it was working and a week or so later the vast majority was nearly killed off. Two weeks later, I touched up some areas that I had missed and some areas of well established weeds that weren't totally dying off yet.

So I was an idiot and didn't put down weed killer earlier this spring/early summer because I was afraid of burn spots and I had crap grass ALL over my lawn. I tried a cheap version of crab grass killer and it failed but had to wait a week or so to really see that it didn't kill anything. At this point I wasn't looking to play around and need to spend top $$ on the best stuff on the market and that's this stuff, Tenacity! I used my own 2 gallon pump sprayer, Surfactant, and a blue dye on my roughly 4000 sq ft yard and I could not be happier with the results! It took about a week to start to see the crab grass weeds only start to turn white and I did another application about 2 weeks later like they recommend. It is now a month later and their is not a single crab grass plant in my yard!!!!! Some of the grass was bleached but after another week of mowing ill cut those grass blades tips off from growth and my lawn will be perfect. In conclusion, buy this stuff and just fork over the extra cash for it. It is worth every penny to not see all the different annoying weeds in your yard. I plan on putting down seed this weekend to over seed and I wont have to worry about it preventing seed from growing which all other products say you cant do. I am going to recommend this to anyone out their moving forward!

Super easy ordering process, product arrived on time. I studied and reviewed Tenacity online from multiple reviewers and it has worked as claimed. Note before purchasing: know your grass type and understand what this product will and will not do. Great product and highly recommended.

Tenacity is definitly killing my crabgrass after second application. It is killing all the other weeds in the yard without damaging the regular fescue and blue grass. Highly recommended. Only needs 1 teaspoon per 2 gallon sprayer.
