Crabgrass finally dead.
I've tried quite a few things over the years, and this is the only thing that will actually kill all the crab grass safely in Bermuda. Follow the instructions, use surfactant, spot spray, and give it time to work. Results are not at the speed of glyphosate, but trust the process and wait. After a few weeks go again lightly on what you under-sprayed.

Great herbicide
Used this on a ton of Silver-leaf Nightshade weeds I had & within a few days you can start to see the difference. Spot sprayed all over and it did the job. I’m happy with how well this worked, instructions are simple, for the value it’s amazing.

Best herbicide I've used for mixed weed problems
This herbicide knocked out the crabgrass and clover that other products couldn't touch. I followed the mixing instructions carefully and applied it with a pump sprayer. Within two weeks, the weeds were dead and my grass looked healthier. The quinclorac formula works well on tough broadleaf weeds too. The smell is fairly strong during application, so pick a calm day to avoid drift. The quart bottle covers a decent area, though it goes faster than I expected on a larger lawn. Overall, it does what it promises and is worth the investment if you have persistent weed problems.

Works on Dallisgrass!
The main reason I bought this is for a severe Dallisgrass infestation all over my lawn. I get my lawn professionally treated and it didn’t stop the Dallisgrass from emerging. I did a lot of research and this seemed to be the best product. I put some sulficant oil with it. Just an ounce per gallon AND I dyed it blue so I could see the progress. It took about a week to start showing. At first the dallisgrass turned purple at the tips. Then a week later it was dried out and looked like dead weed. Unfortunately Dallisgrass is very sneaky and hides between the blades of real grass. So 5 days ago I took three passes and looked as closely as possible for every bit of it. It maybe slightly turning purple but not much yet plus these were harder spots to see. So I’m hoping for the best. It doesn’t get 5 stars because it doesn’t seem to work as well on standard weeds and crabgrass. I’ve tried in on wild violets for the first time 5 days ago and unfortunately they’re still standing tall so we’ll see. Although I think it knocked out my creeping Charlie which is huge, it’s not on the label and I also sprayed some ortho that day so so can’t be completely sure but Charlie gone bye bye. So far I can definitely recommend this for dallisgrass and so just sprayed some more after the three week waiting period on other weeds so I can’t be for sure yet. I will have to update. Just know that there are very little treatments that work on Dallisgrass so to find something is immeasurable.

Works as advertised.
Worked well, but took a few weeks to see the results which was OK because it did not harm my grass.
