Customer Reviews for Prime Source Quinclorac 1.5L Select Herbicide

Seems like I'm always battling something in the yard. This year is invasion of the crabgrass. I missed my summer schedule of pre-emergent and I'm paying the price for it in late July and early August. Won't do that again! Easy to use and in the smaller bottle it even comes with a meter bulb so you can measure out the correct amount. Add the simple amount to 1 gallon of water, add some blue marker dye, and some surfactent and throw it down. I use a semi-fine mist, but have recently switched over to a fan tip and that works much better. Following instructions and not to apply it when it gets too hot I have noticed about a 75% die off of crabgrass on the first application. Only reason why I need a second application is because some of the crabgrass is in that in-between stage where you can't kill it with quinclorac. So I wait a week or two and let those have it again and that does a really good job of getting them. As long as you follow the directions, and the video on how to get rid of crabgrass on DoMyOwn you'll have very good results. Great shopping with DoMyOwn. Great sales, service, and fast shipping. My favorite source for yard-pest-weed management!

After failing miserably with name brand products from local retailers, I watched a DoMyOwn video on Youtube to see what to use on crabgrass. I landed on Quinclorac concentrate in an easy-to-use liquid dispenser. I ordered and paid online and was lucky enough to live 18 miles from the warehouse where the package was waiting for me when I arrived 30 minutes later. This stuff needs a surfactant to stop the water from beading up, so add that to your purchase.

To be fair I had a lot of established crabgrass and I was hoping for total knockdown but this product reduced the issue by about 50%. Good news is I have half the crabgrass I started with, the bad news is I still have half the crabgrass.

The bottle arrived with about 3/4 full but DoMyOwn quickly refunded a proportionate amount. Excellent job killing crabgrass.

Works on leafy weeds, slow. However, not effective on blade weeds like weed grass.

I live in the country and have a large back yard. It is a yard, not a lawn. Some of it is grass, some clover, some lespedeza, and some nuisance broadleaf weeds. It also has clumps of crabgrass which grow faster/larger than anything around them and stand out as particularly ugly. I bought this product to try to eliminate the crabgrass. I mixed and applied exactly as instructed and used the recommended Duo Stick. I applied as a spot treatment to the clumps. This absolutely did nothing to the crabgrass. It actually made it look worse because it killed all the clovers and lespedezas around the clumps. The clumps now are surrounded by bare dirt. Even more of a visual "sore thumb." My purchase of this product was a complete waste of money and the time it took me to mix and apply it.

I had an infestation of crabgrass this summer despite 3 previous applications of Halts (Aug., Dec.,Feb.). Nothing I tried would kill the sprouted crabgrass and it continued to spread. I read on a forum of someone's success using quinclorac and decided to give it a try as I had tried most everything else without success. I used the product as directed in a pump sprayer. Within 3 days the crabgrass began to turn brown and completely died within 5 days. The only negative was that it also killed my fescue in cetain spots but that was not a problem for me as I am transitioning to bermuda after having several large shade trees removed. Now the bermuda can spread more easily. From my experience, I would rate this a 5 star product.

This killed the crabgrass in my yard within a matter of days. None of the products sold at Home Depot or Lowe's work as well as Quinclorac.

Killed all the crabgrass I sprayed in one application mixed with Duo Stick surfactant. Takes a few days for a noticeable effect, but was completely dead within two weeks.

I've had a section of my yard that was sprinkled with crab grass which grew faster than the Bermuda and would look terrible 2days after mowing. In disgust 1year I put Roundup on the area-big mistake. With first application grow was stopped and sprigs of crab grass melded into the fresh mowed yard-very pleased. Will see what it does after the growing season.

I am always pleased with the service and quick delivery times from DMO. In regards to Prime Source Quinclorac, I used Duo Stick as an additive and this knocked the snot out of the advanced crabgrass. I realize I could have waiting until it just died off with the cooler weather coming but I'm impatient like that. This stuff is AMAZING!!! Thanks DMO!

2 weeks after direct application to crabgrass, crabgrass still viable and growing. Should have used Round Up, even if would have killed grass.

It is a great product but you have to read carefully the application instructions to make sure it succeeds. I applied on mid-september in my bermuda grass and it worked.

This product is excellent in killing crabgrass. It worked just as advertised if used according to the directions. It's a bit pricey, but definitely worth it.

This product was recommended for killing crabgrass and several other weeds. It was worth the price, because it worked as advertised.

This stuff is absolutely lethal on crabgrass. I noted changes within a day or two and by 4-5 days it was obvious my crabgrass was done for.

This kills crabgrass in about a week after spraying. May need a second application to get spots you missed, but it kills it dead!
