[This review was collected as part of a promotion.] Pretty convenient to use right out of the bottle. I appreciated that the bottle was sturdy and the sprayer felt much easier to control than your average weed killer. The smell was noticeable, but not overwhelming. I think I’d use it again.

Easy to use and gets the job done!
[This review was collected as part of a promotion.] Very easy to use and gets the job done! This spray was honestly very easy to use- just attach to the hose and you’re ready to go. It works great for those tougher weeds like poison ivy and oak that pop up near the trees and wooded areas and you can spray far enough away that you aren’t getting too close. It comes in a large enough bottle that it treats a big area of our woods and is dry within a few hours!

Effective
[This review was collected as part of a promotion.] Worked great on an area where poison ivy was starting to appear near my steps. One treatment and it killed off the ivy and weeds but didn’t damage my garden plants. Easy to use sprayer bottle, no dripping, stores nicely.

Works Well, but Takes Some Patience
[This review was collected as part of a promotion.] BioAdvanced Brush Killer Plus Concentrate has worked pretty well for controlling tough brush and unwanted growth around my property. It’s easy to mix and apply, and I like having the concentrate because a little product can cover a decent-sized area. It did a good job on several types of brush and weeds, but the results weren’t immediate. Some areas took a while to show noticeable dieback, and a few tougher spots needed additional treatment. O...

Endurance is still a question mark
[This review was collected as part of a promotion.] I was excited to get this product for a small area that is just getting out of hand. It worked great with the first treatment but when the grass started growing back, resprays seemed to have little effect. I can’t blame the product entirely as the weather has not been the recommended conditions but I am also past my deadline for this review. It is a large jug so hopefully I can revise this review soon. The packaging is bright and colorful and w...

Super easy to use!
[This review was collected as part of a promotion.] This was so easy to use - you just hook your hose up to it and turn the dial and spray. It's that easy! It did take a little while before the weeds started dying back. I figured it would work much more quickly. However, it's been a few weeks and they haven't grown back so it seems to do the job well!
From BioAdvanced
Having a simple hose-end setup that makes application effortless is always a win, and we are so glad to hear your lawn has stayed weed-free for weeks!...
Doesn’t work
[This review was collected as part of a promotion.] Product did nothing. Sprayed the whole area per the instructions and it did nothing. The weeds are still there. Didn’t kill the grass or anything.

Average
[This review was collected as part of a promotion.] It was easy to apply and instructions were clear. Two weeks after applying to tall woody weeds, only the flower parts had turned brown. I did two applications to a patch of clover in my flower bed and it did nothing. I had to pull them out by hand.

Great
[This review was collected as part of a promotion.] This stuff is great! It really kills any weeds you have and stops them from coming back! It’s highly effective and the sprayer is so easy to use! I love it!

Effective at eliminating overcrowding weeds!
[This review was collected as part of a promotion.] The BioAdvanced Brush Killer Plus had its work cut out for it on my bank! Very overgrown as I tend to clean it up twice a year. This concentrate was easy to mix with clear instructions and is currently battling all my pesky weeds!

Didn’t do much.
[This review was collected as part of a promotion.] The spray works well as far as coverage. However I sprayed poison ivy and a few other things in these pictures without much effect on any of them. It may need to be a bit stronger to do the job.

Easy and effective
[This review was collected as part of a promotion.] We have been using this everywhere since our yard was a wooded area prior to our house being built. We have a ton of brush and have to constantly clear it. This picture is the next spot we are going to use it. The directions are clear for dilution and it is definitely strong and kills everything and is so helpful to help us maintain. Easy to use. Will repurchase for sure.

Great product- easy to use
[This review was collected as part of a promotion.] With a good amount of poison ivy on our acreage, I really appreciate a product that can take it out! The concentrate is the way to go to mix your own and have it go further. Very easy to use!

Effective in thick brush
[This review was collected as part of a promotion.] The brush killer worked quickly and well. It was a bit slower to work in the shaded areas (about 5 days), but was still effective. In the full-sun area, the brush and grass were completely dead within 3 days. It was easy to use and came with a helpful measuring cup.

Just ehh
[This review was collected as part of a promotion.] Easy to use, very proficient nozzle for spraying. It took about two weeks to even see a difference in the brush I was attempting to get rid of, and it mostly just wilted it. No real visible differences and definitely no wow factor.

It’s a great product
[This review was collected as part of a promotion.] The odor isn’t as strong as I thought it would be! I like that it sprays evenly, I also enjoy that the packaging is blue lol! It seems to do exactly what it says! We love in the mountains so weeds are a BIG thing, especially around my porch, and have 3 kids, weeds are a no go so I spray it around my porch and it works wanders!

Simple to use, easy to aim, very effective!
[This review was collected as part of a promotion.] I have stubborn brush that grows up along the sides of my house and along my chimney, and along the fence line where my neighbor’s unruly yardcare intrudes upon my space. So I was happy to see if BioAdvanced Brush Killer Plus would save my yard, (and save my ears from my spouse’s complaints). And I am very pleased to say both my lawn, side beds and ears are free from what plagued them! You can begin using this product almost immediately…all ...

Works well
[This review was collected as part of a promotion.] This product works very well on brush including poison oak and wild blackberry bushes we have at our home. I was able to kill off a good section after the 1st application. I wish that the sprayer was a continuous spray nozzle for easier and better coverage but overall a good product.
