BioAdvanced Brush Killer Plus Concentrate - Mix & Spray - Kills Tough Brush like Poison Ivy and Kudzu - Visible Results in 1-6 Weeks - Rainproof in 4 Hours - 32 fl oz Bottle

Works great! We have invasive species that return every year. The Asian bittersweet is awful in MI. This takes a while but it kills it!

Don't hesitate to buy it. Follow instructions closely. We sprayed both leaves and roots, though. It rained 12 hours later. In a couple days, leaves began to droop. In a little over 2 weeks, leaves and roots were brown/red and dry. This product helped us with a very large area that had poison ivy (including red vines) and other weeds. We used one bottle in a solution with a large bottle sprayer. You may need a second bottle for a second application-but this product is it.

Worked well. Did a good job on Ivy and Poison Ivy, which was the main objective. A few spots took multiple sprays but better than a lot of other products I've tried.

this stuff definitely kills the brush. if your looking to kill it permanently, this is it. it acts slow, so, be patient. it'll take couple of weeks before you can really tell it's working, but it is. if you want to see results in a couple of days, this product is not for you. be patient and you'll be pleased

Much cheaper buying the concentrate and refilling your container. Have been using this to kill off the neighbors vines that try to intertwine with my fence takes a few days for the results, but main thing is it works!

I haven't used it yet... I do remember that I looked for the concentration needed to kill poison ivy and it says 2 to 5%! This stuff is 8.8% so even diluting it 1/2 and 1/2 isn't overdoing it. I think the ready to use stuff isn't even 1% so it's no wonder that it takes so long or that it even work... I think I'll dilute it 1:3 (one part concentrate, 2 parts of water, which will end up being about 3%) and see how it goes. Will try to remember to post results...

this really works well on tree stumps (may have to use it a couple of times, also works well on weeds. Not difficult to mix up in a gallon sprayer.

It has been 2weeks since I sprayed different weeds,poison ivy, and crabgrass in cracked sidewalk. The poison ivy hardly any die back the other weeds just slight browning. I have used this product for years and noticed almost immediately the results. I feel the formulation has changed. The product is not as potent as before. The label indicates 1-6 weeks before complete results. That's ridiculous, the season will be over. This product is no ways near what it used to be for killing weeds. I will be contacting Bayer. Good luck!! buyer beware. On 8-4-26, I returned to the customer's house that I sprayed for weeds.After 2weeks I actually saw the results. See the attached photos. I was dissatisfied with the results, time wasted and I refunded my customer the money for the job. I was able to return it back to Amazon, the 5th of August was my cut off date. I am now waiting on my refund. I will try another total vegetation weed killer but not Bayer.
