Customer Reviews for BIOADVANCED 40 oz. Concentrate All-In-1 Lawn Weed and Crabgrass Killer

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 stuff really works. Kills weeds and does not harm my grass. It even works on crabgrass, but it takes a while. I recommend this highly.

[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.

I used one time (mixing as instructed), didn’t see any result. Planning to use another time. If don’t see any result willl look for some other product.

[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!

Best weed fertilizer on the market and makes great foam when mixing.

[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!

I sprayed the weeds early in the day and expected them to be looking very wilted by evening, but when I checked them later in the day, they looked fine, and the leaves weren't wilted at all. I went to the store and bought another product and sprayed it the next day and by evening the weeds were dying. They've all turned brown now. I decided to give this product another chance and sprayed it on weeds in the backyard. I used it twice over three days and it was the same experience as with the first weeds, they didn't die. Today I sprayed them with the other product, and they were looking bad this evening. This product was a huge waste of time and money!

[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.

[This review was collected as part of a promotion.] This product has my lawn looking awesome and green. I have yet to see any crabgrass or weeds in my front lawn Since treating it with the spray. Extremely easy to apply the weed and crabgrass killer. So far this year it is working perfectly in our yard. Overall I would not change anything about this product!

Great product and the prompt delivery was very helpful.

[This review was collected as part of a promotion.] This product seems to work as advertised. The nozzle is very easy to use and the spray comes out evenly. I used this product in spots all over the yard. It took about a week for me to notice a real difference. This product does not work instantly, but with some patience, it will work. I would recommend this product to others.

[This review was collected as part of a promotion.] This comes with an attached now though. It is very easy to pump and Amy. You do have to bend over as the tube is not very long. However it does make it easier to aim right at the weeds. There’s also the option of a wider spray and a more precise spray. I noticed the weed leaves yellowing in about a day. I did re-spray some of the more persistent weeds. I think if you don’t pull the roots the weeds will probably still come back for the Persistent weeds

[This review was collected as part of a promotion.] I sprayed this on a bunch of clover. It died ever so slowly over a week or two. I think I even resprayed it. The sprayer on this container probably could have sprayed more liberality than it did. For good coverage my hand was pretty worn out by the time it was done. I think I would recommend this product, it seemed to work ok.

[This review was collected as part of a promotion.] This is a great product. I use it around the sidewalks and driveways to keep everting looking nice. I also use it around my raised gardens to help with weed control. I like the easy spray nozzle as well. I would recommend this for all home owners that want to keep their yard and concrete looking good.

[This review was collected as part of a promotion.] I have had nothing short of a very good experience with this product. I applied according to the directions and got the results that I needed. And it didn't take long to get rid of the weed and crabgrass. I will be using it from here on out for all my lawn needs. And not to mention, it was purchased at a good price.

[This review was collected as part of a promotion.] I love the Bayer - All-In-One Lawn Weed & Crabgrass Killer Ready-To-Spray. This spray is awesome because it is mixed and ready to go without having to complete any extra steps. When it comes mixed already it makes it super easy to use and quick to take care of your outside chores. I would totally recommend this product.

[This review was collected as part of a promotion.] This does have a strong chemical smell, but this works well and quickly. I noticed a difference in just a few days. It is easy to use and sprays well. The mist quickly sprays and the smell doesn't last long, but it is strong at first. It worked quickly getting rid of our weeds in our flower bed and in our yard.

[This review was collected as part of a promotion.] Bayer always makes great products for my lawn and garden but this weed and crabgrass killer is the absolute best. The directions were so easy to understand that I had the whole yard done by the time my husband came home. After the first use I could start telling a difference. My lawn looks nice and neat now.

[This review was collected as part of a promotion.] This year we have seen a different variety of weeds in our yard, and unfortunately it seems that instead of ending them, we are encouraging them to come out more. That's why we decided to try this product. This product is ready to use directly on the weeds you want to kill and we like the fact that you can use it on crabgrass. After the first application we didn't see much change after a week and a half so we decided to do a second application with which we noticed more change. However it was not enough to kill all the crabgrass we have. Even so, we believe that it is a good product and, if you use it constantly, you might see a better performance.

[This review was collected as part of a promotion.] The Bayer all in one lawn weed and crabgrass killer actually works. We have tried many different brands and this is the only one that has given us great results. It was applied to the lawn per the instructions and took care of all the pesky crabgrass. It’s super easy to use. Would definitely recommend!

[This review was collected as part of a promotion.] This All-In-One is truly an all in one. So easy to use and worked great. It has my lawn looking good without breaking my back. Love the Ergo-Grip sprayer (so much easier with my arthritis). I have a small lawn so this 1.3 gallon has actually lasted through several uses. Definitely will be using this again.

[This review was collected as part of a promotion.] This absolutely targeted just the weeds and left the grass alone. After the application there is a fertilizer odor for a day or so. By targeting the weeds you will eventually see brown spots in the yard. At first I thought I put too much on and it killed the grass. However, upon closer inspection I saw it was the weeds it killed which simply blended into the grass prior. I'm thinking I'll just spread some grass seed/ fertilizer mix in those areas and that should fix it up.

[This review was collected as part of a promotion.] This was really simple to figure out and use on my yard. I'm not a professional when it comes to yard maintenance but it wasn't hard at all. It worked like a charm and has helped to keep my lawn healthy and beautiful as we enter spring! I would definitely recommend to anybody needing help with their yard looking great and staying healthy.

[This review was collected as part of a promotion.] I really enjoy using this product. It really got the job done afterwards. Killed the stubborn weeds throughout the yard and haven’t been back up since. It’s very effective and simple to use. Great end results. If your looking for a good weed killer this is the stuff to get. Definitely my go to when needing to get rid of weeds in the yard.
