Best Brush Killer: The Method Decides the Formulation
Penn State: an oil-based triclopyr ester goes on any time after cutting; a water-based one must be applied immediately. Choose the method, then the bottle.

Same active and strength as the other 8.8% triclopyr concentrate here, with the cut-stump instruction printed on the label rather than inferred.
Our Verdict
Read this alongside the BioAdvanced bottle, because they are the same chemistry at the same strength and the honest advice is to buy whichever is cheaper. Its label (EPA Reg. 62719-226-7401) states triclopyr as the triethylamine salt at 8.8%, containing 6.36% triclopyr acid, 0.6 lb per gallon, and it is marked for outdoor residential use only. Two things it does spell out. The foliar rate is 8 to 16 tablespoons — 4 to 8 fl oz — in enough water to make one gallon, with the upper half of that band for mature or hard-to-control plants, which is a more useful instruction than a single number. And for stumps: apply the undiluted product with a paint brush. That second line is why we file it under stumps as much as brush, because cut-stump work is where a triclopyr concentrate earns its place over a ready-to-use jug and where people most often guess at the concentration. Poison ivy, poison oak, kudzu, honeysuckle and blackberry are on the weed list.
✅ Pros
- Label prints the cut-stump instruction — undiluted, applied with a paint brush — rather than leaving you to infer it
- Foliar rate given as a band, 4 to 8 fl oz per gallon, with the top of the range for hard-to-control plants
- Poison ivy, poison oak, kudzu, honeysuckle and blackberry all on the label
- 4.3 across 4,482 Amazon ratings
⚠️ Cons
- Chemically identical to the BioAdvanced 8.8% concentrate here — owning both is pointless
- Label is marked outdoor residential use only, so it is not the product for grazed pasture
- Amine salt, so basal bark work on thick-barked stems wants an ester in oil instead
- Kills desirable broadleaf plants it contacts; the stump method exists partly to avoid that

Where our facts come from
Label read on the registrant's own PDF
EPA Reg. No. 62719-226-7401
We read the printed label published by the company that holds the registration. EPA hosts no PDF for this one, so this is the best available text.
What we found when we read it
Label read 2026-08-02 on the registrant's own site (SKU 11485, 32 oz). EPA Reg. 62719-226-7401 — Corteva base registration 62719-226 distributed by Voluntary Purchasing Group, the same distributor code (7401) as the Hi-Yield products here. Active is triclopyr as the TRIETHYLAMINE SALT at 8.8%, 6.36% acid, 0.6 lb/gal — note retail summaries widely describe this product as butoxyethyl ester, and the label says otherwise. Marked 'For Outdoor Residential Use Only'. Rates: 8 to 16 tablespoons (4 to 8 fl oz) per gallon of finished spray; undiluted with a paint brush for stumps. The PDF is a shared label sheet that also carries ready-to-use panel text — the mixing directions are what identify this SKU as the concentrate.
Where this page and the container disagree, the container wins — the label is the legal authority on rates and restrictions. How to read one yourself.
