Invasive plant killer

Would Recommend

Using this in my woods to clear invasive plants on a 5 year plan. Killing kudzu, wild grapevines and English ivy. Amazed at how well it is working. On my 4th year and most all is dead.

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 ...

This works on even the most stubborn poison ivy

Would Recommend

I bought this because I have poison ivy on the fence that surrounds my property and the guy who cuts my lawn wouldn't go near certain areas because he's allergic. So I bought this and hoped for the best. It took me a while to figure out how to attach the spray but then I went outside and sprayed the area as per the instructions. Next day, the poison ivy was looking worse for wear. I went outside one more time and sprayed some more. Within a couple of days the poison ivy was completely dead ...

Even after 2 applications in the same area, there are no positive results. A total waste of money. Only yhing positive is that the sprayer works good.

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.

Would Not Recommend

Purchased three bottles and they did not work. I used a different brand and it worked right away. I tried to give it the benefit of the doubt and waited a week and still see no difference to the area I sprayed.
