Customer Reviews for QuinKill Max Crabgrass and Weed Killer

I had a full yard of crabgrass. Not just patches it truly had taken over my yard. I was searching for a product with that was legal in NY. This fit the bill and is the same as other products I had found but could not get shipped to NY. I followed the directions on the label mixed it and sprayed. Took me 4 or 5 hours to do the entire lawn. Saw the grass turning orange in about a 4 days and then it died. I dethached the yard and hand raked out the dead stuff. Re seeded and covered with straw and am watching it establish itself. This product did not kill the grass just the crabgrass and clovers. I will add a pre-emergent next spring and keep my fingers crossed. Great product in my experience

This product works well to kill crabgrass in Zoysia grass. Kills crabgrass dead in 3 days and does not phase the Zoysia. It will not kill Oxalis.

I used this in my lawn because crabgrass had almost taken over my bermuda grass. I sprayed it about a week after cutting the lawn and within 48 hours I could see results. It has been 2 weeks since I sprayed and the bermuda grass now has a chance to grow back.

Applied and after 5 days no results. Called customer support and was told could take 2 weeks depending on how long after the crab grass sprouted. It also might take another application. I did notice some yellowing after one week. I mixed 1 and 1/2 oz per gallon of water and used a spreader sticker. I will update this review in a week to see what happens.

I used this last summer to kill several large patches of crabgrass. It took two applications to full deaden the patches but these were fully developed and completey knitted together in my hard Georgia clay. However, even with a late season application in August my Bermuda grass still had enough vigor and growing time to fill in the patches. Now that crabgrass season is back in session the patches that I killed last year have not returned and the turf has returned to its original vigor. I am again using this on new areas that have weak turf, and with any luck they should be patched up by the end of this season. Those who this didn't work for most likely don't have crabgrass or used no surfactant - I used 98 cent dish soap to spread it.

Been trying stuff from local HD with tepid results. Ordered this stuff and followed directions exactly. Sprayed my entire lawn. 4-5 days later every crabgrass plant was brown and crispy. "Real" grass was unharmed. A good way to find any lingering crabgrass is to go out early on a morning that the grass is wet either with a heavy dew or after a night's rainfall. The water stands on the crabgrass, making it stand out almost flourescently against real grass. I found 1 little patch with 4 plants that I probably missed while spraying. If you want to go on a crusade to kill every crabgrass plant in your yard, I highly recommend this product! Just read and follow the instructions and you will be the victor in your war against this insidious weed.

I used a 3 gallon pump sprayer With 5 oz of quinkill max took about a week to see results by the second week it was fully dead. Will recommend it if ur just trying to kill crabgrass.

I bought this at almost twice the price of drive cause they were out of drive half gallon. ($64.00) Bought a pint of this for $38.00. Wanted to kill crabgrass, that is beyond the 3rd tiller state, foxglove, and clover. A week later in hot weather and no rain. Cant tell anything was done. Weed-B-Gone or bayer advanced with less than 2% Quinclorac would have at least turnned crabgrass orange by now.

I followed the instruction for this product from the label. The results were yellowed grass for a month now with no killing of the crabgrass. If it was affected it is not apparent. Expensive with no result that I can see.

I have been fighting Crabgrass for years trying to use preventative fertilizer applications with no success. This stuff dropped the hammer on the problem. 2 week follow up, as recommended, finished the job.

Knowing crabgrass is difficult to kill, I wasn't expecting a miracle when I used this product. Two weeks after using the product, approximately 20% of the crabgrass treated was dead. The remaining 80% seems to be growing very well. Unfortunately, 80% of the grass which was surrounding the crabgrass is now dead. If I knew this was a possibility I would have opted to use Roundup or another non-selective vegetation killer and then reseeded the area.

It worked! The crabgrass is blackened and dead. A few other types of weeds survived though. Overall, way better than the store-bought products. Application helped by purchase of the pump sprayer and methylated seed oil.

Followed directions + used a surfactant, absolutely nothing, increased amount/gal. and double sprayed area and again nothing! Not only did it not work but it was a waste of money and a bigger waste of my time!

Tested on neighboring golf course's crabgrass production farm. Can only say QuinKill Max does the job on crabgrass. Now using on my lawn with great success. Does not appears to damage bluegrass. Test your sprayers coverage with water, then do the math to determine mix ratio. A surprisingly small amount of QuinKill Max and Hy-Yield Spreader Sticker does a great job. Recommend.

I decided to try Quinkill because I had a LOT of crabgrass and foxtail and a variety of other weeds that were resistant to other chemicals. I purchase the home recently and the lawn is in poor condition from lack of proper care. Now to the important part of this review: I did not do a sufficient job of watching the forecast and applied approx 1/2 qt. of Quinkill at a rate of 1.5 oz per gallon with surfactant for spot spraying. Approx 12 hours later we had a heavy thunderstorm with 1.5 inches of rain and heavy wind. Approx 48 hours after application I was pleased to see the product had great results despite the rain.

to be fair with this product, I used Quinclorac 75 DF ist spray, the Pelletized version and following instruction, watered it down into the ground about 7 days later, Now I had doggone near half the yard taken over by crabgrass, and it started to die off , yellowing and turning red, so with 2nd application 14 days later, following the instructions to a "T" applied another dose of QUINKILL Max Crabgrass and weed killer, again watered in 7 days later, Notice I said I had HEAVY infestation of crabgrass, Both products work fine, the crabgrass I HAD is now red, and Yellow and DYING so Follow the Instructions with Correcct dose and a tablespoon of Dishwashing Detergent and it all B gone!! both products work GREAT and this was in Oklahoma and applied in Mid November and below 90Degrees and takes about two weeks to completely die out!!

I don't know what happened, but i followed the drections to the letter and now 4 days after the 2nd application the crab grass is still doing just fine. It didn't really seem to affect anything. It really stinks.

This is my third bottle of this stuff. It works well and does not affect desirable grasses. Crabgrass dies and disappears after a week or two. Always use a surfactant with it. I have no complaints to report.

I've sprayed my crabgrass (wet them down very good) twice over a period of one week between spraying and I see absolutely no signs of the grass dying. I left a few not sprayed for a test, and I see no difference between the ones sprayed and not sprayed. I may try again, but it seems like this stuff just doesn't work.

I'm a skeptical person, as many of my peers. I frankly found it hard to believe that this could be such a "selective" killer. Lets face it, crabgrass is tough! The crabgrass nearly took over my lawn in just 1 year! My lawn was speckled with fescue from last years new sod, I was really worried that it would effect what I had left of real grass. I carefully mixed as instructed using the surfactant blended in, and applied with care. Walla! it decimated the crabgrass, and did not hurt my fescue...pretty amazing. I applied in early October of 2019 and the crabgrass was visibly killed in less than two weeks. Good thing was, I overseeded new fescue seed right after application and now my lawn is looking good! QuinKill, the grim reaper of weed killers!

I tried several attempts to get crabgrass to die in my yard. It would usually turn dull and look like it was going to pass on, but then it would come right back. Even if I did multiple sprayings, I might not see any difference for several days then it would sometimes come back from the same plants I sprayed. Now the good news. I tried QuinKill Max on a suggestion from a friend and it is a once and done magic killer. It's very hot now so even grass is dying which usually lets Crab Grass get an even better start, but it stopped the Crab Grass cold and the grass around it seems to be fine. Great Product. Great Service. I highly recommend.

Applied to a 30' x 30' square of newly planted bluegrass which germinated with a large amount of crab grass. Had applied starter fertilizer with weed killer that had no affect on the crabgrass. Applied quinkill, with a surfactant and after two weeks received a 99% result. Product does work as advertised; I am quite happy with the result after only one application.

First product that I have ever used that is effective against crabgrass in the middle of the growing season. Pre-emergents work, but only during a narrow time window each season. You can apply QuinKill throughout the summer and it will be effective on each application. This product needs to touch the leaves of the crabgrass being treated, so it took multiple applications to treat all of the dormant crabgrass that resurrected itself as I started to fertilize the lawn. I took an overall very bad problem and pretty much cured it in one growing season. I recommend spraying the entire lawn when treating rather than a spot treatment, as you will be amazed at how much crabgrass it kills that is alive and hiding just below the Bermuda. Also note that the product is the most effective when applied at exactly the recommended application rate of 1.45 oz. per 1,000 square feet.

I followed the instructions and spot treated my back yard. I sprayed length wise then width wise to ensure I hit all the crabgrass. Then 3 days later I watered the lawn. Then mowed it on the weekend. I usually bag the grass but the instructions said not to bag it for 3 mowings. I just mowed for the 3rd time and while there are areas that are somewhat yellow, the crabgrass has or is dying. Works as intended.
