BioAdvanced Brush Killer Plus, Weed Killer Concentrate, 32 oz, Kills Tough Brush Roots & Poison Ivy

I bought this for my husband’s grandpa, and he used about half the bottle before realizing he wasn’t applying it the right way. Me and my husband took over, followed the directions, and it worked great! It was super easy to use and covered a good amount of ground. The weeds were pretty high, but it still did the job without any problems. It’s definitely a great value for the money and very effective when used properly. I’d recommend it to anyone dealing with normal weed growth — just make sure to read the directions first! It also arrived on time, which was a plus.

This is a great weed killer. Works great on popcorn tree ( Chinese tallow ). I used this a bit over a year ago and it has not come back.

Last year I applied it as a diluted foliar spray to a small test area on vines that were choking trees on my property at it did good initially but leaves returned. Another area I cut the vines above my head and again as close to ground level as possible and used an adjustable squeeze bottle to slowly dribble undiluted product within a few minutes of making the ground level cut to the open stem/root area. Making two cuts would reduce the chance of new sprouts easily "jumping" the large gap. No new growth formed from the treated stumps so I am proceeding with the two cuts/stump application for the bottom of my property in the Spring and again in the Fall. Although a lot more labor intensive, bi-annual foliar spraying will not kill the crowns for a very long time I imagine, if ever. Species dependent of course, and also depends on how established the invasive is.

This product is so excellent that I feel the need to write a review based on my experience. I applied the product with a spryer to all the vine. One week went by No results and I was upset. Two weeks went by No results and I was supper upset. A friend stopped by the house and I told him the story and he told me to be patient to see the results and that after a month I was going to be so happy. To make the story short he was right. I decide to stop coming to check on the vine for a whole month plus and after around 45 day I stopped to check on the vine. I was so surprised that all the vine was hundred percent dead and it did not grew back all the summer because it was killed from the root out. All I can say is that this is an amazing product but is a very slow process.

I am not a fan of using herbicides or pesticides, but when it comes to nasty invasive plants it's a challenge controlling them only by weeding. Invasive Asian bittersweet is a big menace around here, and this concentrate can be mixed to an appropriate concentration. For 1" and wider stumps, this 8.8% Brush Killer Plus triclopyr concentrate can be painted on just after cutting the plant. Bittersweet rarely gets that big, but full strength stump painting works for other invasive plants such buckthorn, multiflora rose, barberrry, etc. For bittersweet, I follow a method recommended by extension services, which is to cut it back earlier in the season, and then wait until ~August - September to carefully spray the new growth. Late in the season is when plants are sending more of their sun-produced sugars to their roots, so the herbicide kill is more effective then earlier in the season. I also mix a 1-2% solution (4.5 units of water to each unit of concentrate yields 1.6%), which is stronger than the 0.8% solution found in the ready-to-use version. But you may find the standard dilution to 0.8% effective. Compared to the also-popular glyphosate herbicide, trichlopyr is "selective" in that it does not injure grasses as glyphosate does. But triclhpyr is somewhat more persistent (doesn't break down) in soils. This Brush Killer Plus Concentrate is water-based, low odor, and easy to mix in garden sprayer. I make sure to wear protective clothing- Tyvek suit, old boots, heavy duty water gloves, and eye protection. Important to spray on a relatively calm day with no rain expected in the near future. Great to see areas that were once infested in 95% bittersweet showing a variety of native plants the next season. That is the ultimate goal: native plants that are good pollinators for insects and other animals.

This stuff is slow killing, is an understatement. (WEED KILLER: Start seeing visual results in 1-6 weeks). That's just too long to wait, six weeks is nearly half the summer. What if you missed something, then it's another six weeks of waiting to see if your weed will just die of old age. Round Up is much the same, maybe not quite as long of a wait period. Spectracide on the other hand has worked well for me. Spay today, and one can definitely see the weeds dying by tomorrow. If you missed something you can spray again without having to wait half the summer.

Used this to finally rid myself of those day lilies that nothing else could kill. Originally bought to kill ivy and some brush and it did that job well, but I decided to try it on obviously Roundup proof day lilies and it knocked those down too. If anything sprouts back up I'll be sure to grab more to knock it down.
