It works

This product definitely works. The Tenacity is pretty thick so you really need to get it mixed in. First couple days I didn't see anything but then the clover and other weeds started showing up yellow then white. I didn't have a flat tipped spray head, I would 100% recommend that. The only reason for 4 stars instead of 5 is that blue dye is a PITA. If you are spraying along edges of your lawn that have concrete I would recommend doing those areas BEFORE adding the dye. I was extremely careful but still had a few areas of overspray which I had to scrub off with a brush. The dye came off where the concrete was sealed but the other areas have lingering light blue stains now. Cleanup is a bit of a pain also. If you have a fairly square lawn and can easily keep track of where you've sprayed I would not get the dye.
2 weeks in

I almost went with 5 stars but I just dont know enough yet. It will be 2 weeks tomorrow from the first time that I used Tenacity. After 1 week, my crabgrass began turning white. I just noticed yesterday that the clover weeds had begun turning white. I have some other weeds in my grass (not sure what they are) but i don't think I've noticed them turning white yet. This is only my first application and I used dish soap as a surfactant. I am thinking about investing in a true surfactant for my second application next week, we will see how it goes.

Almost perfect

Did two applications per instructions with NIS 2.5 weeks apart. So far the dandelions are nearly gone and the chickweed is really stunted. Unfortunately only the very young clover has died off and even more clover has grown in the last 3 weeks. Any advise would help here.

Works great on some weeds
By Dinesh on 08/21/2020
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.
Did its job

I applied the product heavily (first time using). Bottle should have covered three acres, I only used it on 1.5. Had to apply second application with yet another bottle....this time applied in a real hurry. Took out all of the crabgrass, and 75% creeping charlie, but only about half of barnyard grass. Overall, better than other products I have used. Am concerned that some of the bluegrass has turned white, but it is not dead....at least not yet. LOL.
