BioAdvanced 32OZ Weed/CRBGRS Killer - Kills Weeds & Crabgrass, Covers 12400 Sq Ft - Spray Form

Was very very impressed with this. It took a month or two to work fully but ALL my dandelions in the lawn went!!! Thoroughly recommend it. Maybe be careful when you apply re kids/pets -but is clearly good stuff though. Thank you 😃

Seems to have done to trick on killing crabb grass and other weeds. Effects take about 5 days to see with the slight yellowing of the grasss as it works its way to the root. I have cut my grass and there seems to be much less crabb grass and weeds growing back, hasn’t killed every weed but most of them and I have plenty still left in the bottle

Crab grass has been the scourge of my lawn for years. I tried keeping the lawn super short and pulling it out, but nothing short of tearing up whole sections of lawn and reseeding seemed to work, until now. This does kill, or at least badly yellow, crab grass on a first application. It’s not systemic so it looks like it will need a few applications to get it all, but I can’t tell you how much I enjoy watching this weed die off.A few words of caution, the instructions are in imperial old school measures, so it’s easy to miscalculate exactly how much weed killer to add to a quart per furlong but over dosing doesn’t seem to harm normal grass too much. The delivery is also impossibly long. After a couple of weeks I checked what was happening and the eta on a new purchase was quicker than my old order.

I bought this in July last year and thought I'd wait till this year to leave the review. I had a fair amount of creeping clover, loads of patches of crab grass and a few other odd weeds. This took a couple of weeks to arrive, however it did come from America, so be prepared for that. However it worked amazingly, a very small dose by comparison to other week killers you woukd use in the UK, after the first week the flowers on the clover has all died off, the leaves had withered and the thick vines were starting to shrivel up, the crabgrass looks half dead, as if it hasn't seen water for weeks, so I gave it a second going over with the weed killer, a week later literally all of the crabgrass had withered away and was dead, the clover was non existent as we're the other odd weeds, I was left with patchy grass where the crabgrass and weeds had been killed. All I needed to do was cut the grass very short, take the lawn rake over it to get all the dead stuff out and then over seed and water it in. Grass looked excellent after a month or so. However I thought I'd wait till spring this year to see if loads of crabgrass popped back up, and I am happy to say I had 3 patches, each about the size of a tea plate. So this has been great success.

The bane of my life was crabweed - this year it has gone. This stuff is not cheap and neither was my time spent digging it up. Now I just spray and get on with other stuff. Have recommended it to friends

Does not work killing ordinary or extraordinary lawn weeds, let alone Crabgrass. I applied the correct dosage for my first treatment, sprayed my lawn and waited the recommended couple of weeks, and nothing, weeds happily growing, Crab grass laughing away at me. Second treatment I effectively upped the dosage by a factor of 5 times the recommended dosage and carried on to waste the next 30 minutes spraying my lawn again. 3 weeks later and absolutely nothing has happened. I only bought this product as it was a supposedly targeted Crab grass killer so im not overly bothered that it does not common kill weeds like clover etc because there are Weedol products that do, but for it to do absolutely nothing to Crab Grass at this price is taking the proverbial. If you have weeds of any sort, then avoid this product, it likely might kill something because it smells like it should, but im yet to grow that thing on my lawn.

Excellent quality and value for the money, no issues experienced delivery was spot on would recommend no problemReally pleased

Oh yes it works!

I take great pride my pristine landscaping and especially my lawncare, however neighbors who have properties on both sides of my property (I live on a city cul-de-sac) are very neglectful about performing any type of care when it comes to basic lawncare and especially their weed control. 'Crabgrass' being the nastiest of their spreading invaders that take hold and attempt to creep into my lawn area.The first two images are of their typical Crabgrass infestations; these Crabgrass patches happen to be in the curb-strips between the sidewalk and the street (which the city really owns, so I can then treat). These have been steadily creeping my way, so using a hand-pump sprayer, I mixed 4-oz's of the 'BioAdvanced All-In-One Lawn Weed and Crabgrass Killer' to 1 gallon water and I sprayed these patches twice over a two-day period and I'm happy to say that as soon as day three that it's already working as the centers of are turning brown and dying. So, when you spray, hit them hard and a second application on the next day is really good insurance.The new 'work from home' environment keeps people in their houses and unfortunately lawncare isn't inside, so lawncare gets neglected! Bad neighbors!

Normally crabgrass laughs at most broadleaf killers. If you want to kill it you have to choose a product that says expressly "with crabgrass killer."We had a long thick strip of crabgrass that arrived this year. When I say long and thick it was a foot wide and close to 25 feet long. We've always had a problem with the back yard in our rented home, but this was the most concentrated as I have ever seen it.The product, like all weed killers does not smell good, and the smell lingers on the lawn for several days.I received the product June 10 and used it at a slightly stronger mix in my hose end sprayer. This is what it looks like on June 13. I am doing the happy dance!

I bought this to rid my yard of spurge. Nasty things. I sprayed this and things started dying in a couple of days. They look unhappy almost immediately nut in a couple of days the leaves turn brown. Then they stop standing up so the are not as easy to see from across the yard. After a week or ten days, problem almost solved. I do not get 100% but my problem was large. I am down to a few here and there. Not sure how the crabgrass goes. Very good product and I bought more. I assume they will keep coming back. I assume one of my neighbors need to buy this.

Plumbing work tore up our backyard, and dock weed took over. Both curly leaved and broad leaved. Big, huge Jurassic looking bastards just trying to flower and take over the entire neighborhood, once they dominated and suppressed all my pretty plants. I asked my father what I could do? Constantly cutting them down didn't help, I wasn't about to dig up 500 plants with taproots 5 feet long, and the brush killer I have for poison ivy and trees of heaven wasn't doing anything. Dad suggested this stuff. I mixed some up in a spray bottle and tested it on a broad leaf dock in the front yard that was competing with my hostas. I carefully sprayed the leaves of the weed, making sure to saturate them, and within two to three weeks, the weed was completely gone. So I attacked the jungle in the back. Because some of the weeds in the back are ENORMOUS it's taking a few applications, and may take all summer to kill, BUT THEY ARE DYING. And that's all I care about. Trees of heaven and dock weed can burn. This stuff at least gets the dock.

Product is not strong enough to actually kill brush it shocks it for maybe 1 month and it comes right back will never buy again
