what's the percentage of triclopyr?

It depends! 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.

Has anyone tried this on english ivy?

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

Wondering what the mix ratio (ounces per gallon) is required by the concentrate?

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.

We have killed everything topside, but we have roots coming in to the basement, will this work if directly applied to those roots?

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.
