Primesource Quinclorac 1.5 Select Liquid Crabgrass Killer 7.5 Ounces

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

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

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.

Second purchase for this product which works well on our lawn.

Why did you pick this product vs others?:It’s a killer

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 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 mixed the herbicide as they suggested for the crab grass, mowed the lawn 3 day prior, sprayed the crab grass and then also lightly sprayed the whole lawn - it's 4 weeks later and very few of the crab grass has died. It did kill some of it and thus the 1 star. IF it kills 10% of the crab grass I would have given it 2 stars. This is really a disappointment as I so hoped it would work - esp after following the instructions super carefully seeing this is NOT a cheap product. I even cut the water to my garden for 2 days after I sprayed the grass. I will NOT RECOMMEND this product and sadly feel I wasted money on this and cheated!
