Quinclorac 1.5 Select Liquid Crabgrass Killer 7.5 Ounces

Works as advertised. Definitely the best crab grass killer that I have used! I highly recommend it for established crab grass.

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.

I applied this per the instructions. Used the proper methylated seed oil. It went on a little heavy. It may have killed some weeds, hard to tell. But the crabgrass is still there. I tried a second application with what I still had left, and unfortunately it rained the next day, so no clue if it would have worked. -Changed review to 4 stars. It took a while, but it definitely worked. This is my lawn about a month later. Most of the crabgrass is dead.

Bought this for Dallisgrass. It is working very well. Have sprayed twice and a lot of it will pull up my hand now and all of it is dying.

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

Used this product on fox tail and crabgrass during summer in cool season grass. Super effective

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.

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
