Amazon is selling multiple concentrations of this product all grouped together, and their product descriptions do not make this clear. The "Concentrate" seems to have 8.8% triclopyr, but the "ready to use" gallon and 1.3 gallon sizes are diluted 10 times from that amount...my 1 gallon bottle says 0.8% triclopyr, 99.2% other ingredients. Be careful which one you choose! I thought I was getting the 8.8% and so am sending it back. **Q: Has anyone tried this on english ivy?** A: I used high concentration of plain salt on 20 yr ivy that i was going to replace w black star gravel It took a LOT of mortons salt but it worked for not much money **Q: Wondering what the mix ratio (ounces per gallon) is required by the concentrate?** A: Add 4 fl. oz.(1/2 cup, 8tbsp) to 1 gallon of water to spray on brush. Brush undiluted to kill Kudzu, Poison Ivy, Poison Oak, Blackberries, and also stumps and root sprouts leaves. **Q: We have killed everything topside, but we have roots coming in to the basement, will this work if directly applied to those roots?** A: Go on Amazon and purchase "Bonide Stump and Vine Killer". It has an applicator to apply the product directly on freshly cut roots. Killed all my roots dead, right to the bottom. Hope this helps. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great *by K***Y on 13 July 2026* Works great! We have invasive species that return every year. The Asian bittersweet is awful in MI.

Will keep using this product until my yard wins the war against these woody invasives ### ⭐⭐⭐⭐ Works ok, but missing measuring cup *by B***A on 17 August 2023* 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. ## Frequently Bought Together - BioAdvanced Brush Killer Plus, Concentrate Weed Killer, 32 oz – Kills Tough Brush Roots & Poison Ivy - Chapin 20000 Made in USA 1 -Gallon Lawn and Garden Pump Pressured Sprayer, for Spraying Plants, Garden Watering, Weeds and Pests, Polypropylene, Translucent White - Ortho GroundClear Year Long Vegetation Killer2 Concentrate, Kills and Prevents Weeds Up to 12 Months, 32 fl. oz. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/358128492-bioadvanced-brush-killer-plus-concentrate-32-oz-kills-tough-brush](https://www.desertcart.co.uk/products/358128492-bioadvanced-brush-killer-plus-concentrate-32-oz-kills-tough-brush) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-11-03*
