I'll use again but only in certain circumstances
This product works extremely well for Crabgrass but I did find that a second application severely stresses the Bermuda grass that I'm trying to cultivate. It's weird because the first application only killed about half of the crabgrass and zero Bermuda grass. But the second application killed 100% of the crabgrass and probably about 30% of the Bermuda grass

Works on foxtails
Great, it killed most of my foxtails, yet I need to apply a 2nd time to get the remainder of them. Although it is a little pricey

Effective, but
I used this on crab grass in a Bermuda lawn - in mid September, North Georgia. Highly and quickly effective on the weeds but it really set back the Bermuda. I think it would have fine if I used it earlier in the growing season. Cool temperatures and dry conditions have probably slowed the Bermuda recovery. Next year I will mix a little weaker than recommend.

Kills crabgrass at 5 til , don't overuse it
This is one of the three products that Kills crabgrass and variants that few other products affect. But it's hard on the grass and the environment, wildlife will leave for 2+ months. If you properly meter it, you can have a max of two treatments a year. If you overuse it, the weeds will adapt and you'll no longer be able to use it. It works much better with the correct MSO sulfucant I'd recommend this product as a strong crabgrass herbicide that has fast 3-14 day knockdown. The only other fast knock down crabgrass herbicide is Acclaim Extra Selective, which in some ways is superior, but is more expensive and is not easy to find. If you are treating earlier in the spring consider using Tenacity instead as it acts as both a pre and post emergent, but be aware it works slowly, growth is stunned then slow death, and has some other specific application and watering requirements if you go that route.

Great crab grass killer
My St. Augustine lawn was taken over by crab grass in several areas and had resolved myself to having to dig it all out. Decided to give this a shot and so glad I did. Sprayed the yard a week ago and all the crab grass is now browning and on its way to dying. And no damage to the St. Augustine either.

works but not as effective as others, you need to double the dos
works but takes forever, it is not as effective as other ones i have used. You have the double the dose to speed up and terminate the roots permanently with this product. Quinkill Max gave me better results, where it kills and does not come back from the same roots with the recommended dosage. They will both hurt your bermudagrass but bermuda always recovers, especially if you fertilize 1 week after applying herbicide.

It works
I live on Long Island I bought this product received it and applied it on a Friday, by Wednesday my crabgrass look like cigarette ashes I am not kidding. When applying this product I made sure the temperature was between 70 and 80° nothing higher nothing lower,for my measurements I applied 3 tablespoons per gallon I had a 2 gallon sprayer so I put 6 tablespoons inside of it I mixed a little surfactant which is like the soap so that it would stick to the leafs and I mean it really worked and targeted only the crabgrass, did not harm one blade of grass I was amazed I mean it literally suck the life out of the crabgrass without damaging anything else it would be nice if It killed other weeds also but I was very very pleased. And the crab grass was adult size large crabgrass not little Sprouts.
