Customer Reviews for Tenacity Herbicide

As with most folks, I was expecting to spray one day and see dead weeds the next day. Well, it didn't work quite that fast but within 2 weeks all of the clover was dying. I haven't looked for or seen any crabgrass and there are still some dandelions here and there. I will apply again when its time. There is enough left for at least one more application. Clover was my biggest problem, and that problem has been handled. If the second application gets rid of my other problems than this product deserves 5 stars.

Creedmoor NC , tall fescue and RTF fescue lawn . 2 gal sprayer over entire lawn, rain followed three days after . Weeds faded after two weeks , some minor bleaching of fescue . Bleaching of Orchard grass and Creeping Red fescue is more visible and fine if it retards their growth.Follow up spray may not be needed.

I live in SC and have used other less effective home ceneter products for years. This has been very effective against the tenacious crab grass and a lot of other weeds. I highly reccomend this over the gneral products that you find at a home center.

The products came packaged very secure. I was happy that the tops were reinforced and secured with bubble packing. Very nice and exactly as described. I mixed it and used just as instructed. I am excited to see the weeds start dying.

I initially thought this product wasn't going to work because I mixed it with Speedzone and the speedzone worked practically overnight. But in about 7-10 days I saw the results towards the grassy weeds. It took them out completely. Have to use it when's it's cool if you are in warmer weather. A must have in your weed killing arsenal.

Used Tenacity with speedzone on 1 acre of my 2 acres as a test in September. Spring of this year I have zero dandelions in the 1 acre I used it in!! Worked amazingly and I just ordered a second bottle for this year and will be using it yearly!! 100% recommend

Well I’m not sure if how good it really is. I applied it once two weeks ago and am just now seeing some results but very slightly. It wasn’t supposed to rain the next day after applying to lawn. But it did. And it keeps on raining. Am going apply second treatment as soon as I can get a break from the rain.

It took over a week to work. Just follow the directions it only takes a small amount. Great stuff.

This stuff is good 4oz to 15 gallons of water on about a acre.

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.

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!

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.

Very happy to find a product that kills henbit for a year. Reasonable price for the product and not difficult to apply.

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.

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.
