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!

Amazing! I was tired of cutting down the bittersweet that is consuming my back woods. This spray is wiping it out! it destroyed an invasive everlasting primrose within days. The bittersweet is showing it is being attacked about 2 weeks later! I spray a stump of a black locust and it stopped producing runners within days! Will keep using this product until my yard wins the war against these woody invasives

I've ordered this brush killer a few times through Amazon. At around $15-$16 it is less expensive than at the local home improvement stores. It delivers on time every time I've ordered it. The bottles come with a seal under the cap so I've had no issues with spillage during shipping. When used as per the instructions it works to kill brush weeds like lambsquarter, poison ivy, etc. and other hard to kill weeds though it takes a couple of weeks to see the results on some weeds. So some patience is needed. I've also used it to kill small tree stumps up to 4 inches from trash trees that sprout around our property, though you have to use it undiluted on tree stumps for it to work. So far it seems to work. The tree stumps look like the wood dries out gradually. My one complaint is that the last two times I've order this product through Amazon the measuring cup was missing. Previous orders came with the cups, but last two orders were missing the cup. I can see how easy it is for the cup to fall off during handling as any slight pressure can make it pop off. Not sure if it's an Amazon warehouse handling issue where it falls off during their handling of the product and they now have a collection of the measuring cups or if it's a manufacturer issue. In either case better quality control is needed to ensure each bottle ships with its measuring cup. Fortunately, I still had a measuring cup from a previous purchase so wasn't a big deal for me. For someone else it might be an issue if they don't have a measuring cup since you need to measure the amount to use per gallon of water. It takes anywhere from 4oz to 8oz per gallon of water depending on the type of weeds your trying to kill.

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

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.

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...

Brush and berry bushes were getting out of hand on the back part of the fence line. I may or may not have used the recommended dilution according to the EPA. Filled a 2-gallon sprayer and decimated the brush. It now looks like a post-apocalyptic wasteland. This stuff works!

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.
