BioAdvanced Weed and Crabgrass Killer Concentrate - Case of 8 - 40 oz

If I could give a negative star I would. No colored area like claimed spray does. No change in weeds claims to kill. Crap product. Will not buy again.

I used this Weedkiller on my Crabgrass as directed and it has KILLED my bermuda grass that got the overspray, and the crabgrass is still thriving!!! The instructions clearly state this is SAFE FOR BERMUDA LAWNS but it IS NOT!!! This is the DEAD bermuda that got the overspray from my spraying the crabgrass. I need to get someone with this company to take ownership in this problem and pay for a service to come out and dig up the dead bermuda spots along with the Crabgrass and replace those spots with bermuda sod.

After three generous applications over 1 week with this product, there has been very little effect on my weeds. It stinks for days, but that's about it. Will not repurchase.

Been using this for years, but the last two bottles seem to have been a different formula. Recommended mix (3.2 oz/gal of water) started killing grass along with weeds, expands quite far from the sprayed weed. Then I cannot get nee seed to grow there without replacing the soil at those spots. Did the formulation change?

Just bought this a week ago. Did per the label for installation. I don't see any changes with either grab grass or weeds. They seem to grow at the same rate they were previously with no evidence of dieing.

I bought this2 weeks ago. Today, the Farsi day of use, it would not work (the spray mechanism). I followed all directions. The batteries were charged. Another piece of expensive garden junk!!!

I have no idea how anybody gave this product anything higher than two stars. I used the concentrate on the dandelions in my grass at double the recommended dosage and the dandelions just laughed at it. Actually, they browned a little bit, but they never did die despite two applications. Worst weed killer ever!

[This review was collected as part of a promotion.] the price is insane for what you're getting, with ingredients that are safe for the environment around where you spray, same with pets. My job had me taking care of a large bed with flowers in it and the last thing I wanted was weeds to ruin my hard work. Using this kept all the weeds away and allowed the flowers to thrive! Usually these don't work, or are bad for pets nearby but this is the opposite! If you're a pro or casual please make sure to pick this up to keep your garden weed and pest free.

This is supposed to be an all in one but it didn’t kill and single one weed. Sprayed on extra heavy and it didn’t rain for a week after spraying. Save your money and try something that works.

I use BioAdvance All in One till I ran out. Found a half bottle of Gordon's in my cabinet. BioAdvance treat still Green, Gordons brown and dying spray 3 days ago.

[This review was collected as part of a promotion.] I’ve used a number of weed spray and this product actually works! Sprayed it on a bunch of weeds I was getting in front of my house where the flower bed is and it worked like magic. Saved me hours of weeding. Easy to use and didn’t smell too strong. Best to use before the weeds get too tall though. Will be using in the back yard next :)

I've read the information on the container twice and nowhere can I find how much water to use to dilute this product. I expect it to work OK, if only BioAdvanced cared enough about its customers to tell us how to use its product.

I sprayed a test patch on a heavily weeded area of my yard which produced good results - the weeds died within a week of application. A few weeks later, I went to appl the product on my whole lawn using the hose-end sprayer, but I noticed that the level of the herbicide in the bottle did not decrease after a while. I was only spraying water on my lawn. Now I have to buy a sprayer to finish the application. Save yourself time and buy the concentrate and a sprayer...

[This review was collected as part of a promotion.] I have always enjoyed Bayer products. they always deliver on any claims they make and this is no exception. had the usual problems with weeds growing through cracks in the concrete and crabgrass throughout my lawn and with repeated treatments they were killed off. while I try to avoid chemicals in my lawn. Bayer is definitely a company I would use.

[This review was collected as part of a promotion.] This stuff works well! We used it after the spring bloom of weeds took over our yard. It's easy to pick up and start spraying the roots after you've pulled and cut the area. We saw the roots dying within about 24-36 hours after spraying. Unfortunately, our area is pretty riddled with weeds so we have had some spots come back but we bought ourselves a good 3 months!

[This review was collected as part of a promotion.] Over several years of growing up, I’ve tried different brands or weed and grass killer and this has to be one of the best ones I’ve ever used! Works almost instantly! Very simple and easy to use without all the hassle like other products on the market. This is a go to for any of your outside lawn care to get rid of unwanted grass or weeds!

[This review was collected as part of a promotion.] We use this in our courtyard where weeds are constantly popping up through the gravel. One easy application with pinpoint accuracey got rid of them super quickly. It had much less odor than other brands I've tried, and I couldn't be more pleased! I highly recommend this weed killer to anyone who has a weed problem!

[This review was collected as part of a promotion.] The Bayer All in One Lawn Weed and Crabgrass Killer is very convenient as it is pre-mixed and you do not have to do the measure and mix into another container. This product is effective in killing crabgrass and weeds. I like the sprayer and feel like you have good control over the spray. I wish the product was more natural based, but it is effective and works as advertised.

[This review was collected as part of a promotion.] Living in rural Kentucky I got all kinds of weeds. This does a pretty good job if you spray at the base of the weeds. You can't just spray the whole plant on top like some weed killers. If you shoot it at the root and it's more effective. I have killed some stray blackberry bushes because I didn't want my dogs stepping on the thorns.

[This review was collected as part of a promotion.] This weed and crabgrass killer really works. I used it in my lawn and around the landscape to kill the crabgrass and weeds. Within hours it started turning brown and dying. I did have to go back and reapply but overall, it worked the first time applied. I would recommend if you have pesky weeds and crabgrass you are looking to get rid of.
