BioAdvanced Brush Killer Plus, Ready-to-Use, 1.3 Gal – Kills Tough Brush Roots & All, Kills Poison Ivy (Pack of 2)

This stuff works wonders on blackberry bushes. but then you have all those dead branches to clean up. You do need to leave a period of weeks and then come back and spray again. It is not a one time fixes all, but it is working.

Works well. It will kill whatever plants you spray it on.

I purchased this product the first week in April of this year and sprayed some wild black berries around my yard,,,They are still black berries and still growing. I guess I will have to buy some Roundup, I know it will kill them. I was making attempt to get away from using Roundup and make my neighbors happy. I think I would rather have unhappy neighbors than wild blackberries. MAY 10th**** I need to amend my harsh review,,,I went and looked where I had sprayed my Blackberrys that was invading my yard yesterday and I think they are all dead. So It Does Work..

Kills the Japanese knotweed and thorn vine infestation same day. Spray on a sunny day and watch them wilt. Keeping a whole forest of these out of my yard by simply spraying over the fence...spent weeks getting them out before I found this.

Let me start by saying, I have always liked this brand. However, I am completely disappointed in the sprayer that came with this product, it is cheap and split right down the seam after a few minutes worth of use (maybe 9 or 10 trigger pulls - yes it was on the spray position) the plastic trigger fell off and it was useless after that. Buyer beware! I had to poor the contents into another spay bottle I had so I could finish the job. But most of the product dripped all over the ground. So disappointed, I will never buy this brand again until they change the sprayer design.

DO NOT buy this! It doesn't work!I'm 76 years old, on a fixed income, and i do volunteer brush and vine control and cleanup in cemeteries out of respect because the overgrowth consumes grave markers and kills big trees. I bought two gallons of this for the first time to the tune of almost $58, sprayed everything thoroughly in dry, sunny weather. A week later, there is ZERO wilting or withering! ZERO! It's like I sprayed water on it!!I explained this to AMAZON, who is UNWILLING to make this right! What little that is left is leaking through the spray nozzle and it's too toxic to send back!They want to give me a total of $11 refund!!!!! Totally dishonest! If they allow products on their site, they damned well ought to guarantee them! I've been with Amazon 20 years and have returned very few items! SHAME on them for stealing from loyal customers!!!I'd cash the company, but there's zero contact information for them! It's just not right. :(

This is an excellent weed killer. I had a lot of Kudzu in my yard. It has killed and controlled it better than anything that I have used in the past!

Good product
