Bayer Advanced 704640 Brush Killer Plus Concentrate, 32-Ounce by Bayer Advanced

I have to purchase this chemical plant killer, unfortunately, to deal with the massive infestation of Oriental Bittersweet vine that I'm trying to manage in the woods of my property. These types of invasive, strangling, suffocating vines need the Tryclopher chemical to do the trick. I mix this concentration with a dilution of water in a pro-spray bottle, cut the vines as the base and then just squirt some of this highly effective stuff into the cut ends, down into the roots. For old growth vines, I barely dilute it, to ensure effective death of the vine's extensive, insidious root system. It also does a great job with Poison Ivy and Virginia Creeper vines, using the same method. It's a good value for the money paid. The bottle really goes a LONG way.

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 does kill the leaves that you sprayed on it, but it did not kill the poison Ivy that I needed gone from my bush but it did kill the leaves on the bush around it. I'm trying it again and will give an update to see it maybe it was applied wrong.

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.

The product description claims it kills wild violets. The violets that currently dominate half my yard just laughed at it. Absolute death on crabgrass though. Three stars, mostly because I no longer have crabgrass in my yard.
