BioAdvanced All-In-One Lawn Weed and Crabgrass Killer I, Concentrate, 40 oz

I'd bought this before at my big box home store, but they don't sell it anymore but I found it here. It really seems to work for me. Kills the weeds but feed the grass. I like that its a a concentrate because I hate paying for added water. I can add water myself.

My lawn was invaded by crabgrass this past spring. I applied this once and within a couple of weeks, no more crabgrass.

Update- so I guess it does kill crabgrass. Eventually. And it seems you need to double up the dose. So if that's your plan give the gallon of water a full cup, really soak those weeds, then wait about 10days or so. Old-Says crabgrass. Absolutely does NOT kill crabgrass. Only reason for purchase. Even doubled the mix on second dose. Crabgrass just keeps on growing.

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!

Worked on 1/2 the weeds. Still have crabgrass. 🫣 the crabgrass turned purple on the tips but never died. Mowed and now it looks like i didn't do a thing. Did take out most of the clover and some other waxy broad leaves weeds.

Works Great and Delivered to the Door - Step eliminating Driving around looking for the Product.

It doesn’t kill weeds. This stuff sucks. We sprayed a week ago and nothing died. Sprayed again at 2x concentration yesterday and no sign of death. Tried it because it was supposed to be better for the environment but my lawn is full of weeds so I have to try something else.

Yes. I love this product. I bought a spray bottle of it here in town. Quite expensive. While reading the back of the bottle I read to buy this bottle to refill the original I bought. Wow, so much more affordable! I tried the product on wild geranium. I was getting clumps of it in my grass. It’s a beautiful weed and I don’t mind letting it take over a few of my beds but NOT MY GRASS! It made some of it turn color, some die the first time I used it, and I used it again and my problem was gone. I attack it about every two weeks now. It’s getting rid of it, it’s new stuff I continue the fight with. I really like this stuff. I’ve also used it on dandelion and other weeds I find in my grass. I recommend it. Especially since this is the refill bottle. Much more affordable.

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.

The weedkiller is easy to use but some of the crabgrass needs some more. You can smell it for days!

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.
