Listed here so the answer is on the record: this is the triclopyr and fluroxypyr combination people find while shopping for lawn weeds, and its label does not cover residential turf.

Our Verdict

Genuinely good chemistry aimed at a job that is not a lawn. Triclopyr plus fluroxypyr is a strong pairing against woody brush and the tough broadleaves — brambles, thistle, woody regrowth — which is why it turns up in searches for hard-to-kill weeds. The reason we rate it three stars is the label, not the performance: PastureGard HL is registered for pasture, rangeland and non-crop use, and the pack itself carries 'For Use In Registered States Only'. Applying it to a residential lawn is off-label, and using a pesticide inconsistently with its labelling is a legal matter rather than a preference. If you own grazing land or unimproved acreage, this is a serious product and the price makes sense at that scale. If you have a lawn, buy a product whose label lists lawns — a triclopyr-containing turf herbicide exists and is a fraction of the cost.

✅ Pros

  • Triclopyr plus fluroxypyr is genuinely effective on woody brush and tough perennial broadleaves
  • Concentrated — economical per acre on real acreage
  • Selective enough to leave pasture grasses standing
  • The right tool if you actually manage grazing land

⚠️ Cons

  • Not labeled for residential lawns — lawn use is off-label and that is a legal problem, not a judgement call
  • 'For Use In Registered States Only' — availability and registration vary by state, so check before ordering
  • Priced for acreage; nonsensical value for a suburban yard
  • Triclopyr can injure ornamentals and trees through drift or root uptake
  • Restricted-use style handling for a product a homeowner has no labelled use for

Where our facts come from

Label read on EPA's label database

EPA Reg. No. 62719-637

Read the label yourself →

We opened this product's accepted label on EPA's own Pesticide Product Label System — the strongest source available for what a product is registered to do.

What we found when we read it

Label read 2026-08-02 on EPA PPLS. Acid equivalents: triclopyr 32.4% (3.0 lb/gal), fluroxypyr 10.8% (1.0 lb/gal). The woody plant table lists poison ivy (printed 'ivy, poison') with no footnote, and kudzu with the footnote 'Repeat application may be required' — which is why this product carries both the poison ivy and the kudzu guide. Woody plant timing on the label: apply only after leaves are fully expanded and terminal growth has slowed; if brush was mowed, allow 9-12 months of regrowth first. Broadcast rate 1.5-4 pints per acre. Grazing and haying: no grazing restriction for livestock or dairy animals on treated areas, do not harvest hay within 14 days, and withdraw livestock 3 days before slaughter. CLOVER WARNING recorded 2026-08-20. University of Arkansas Cooperative Extension (MP44, Pasture Weeds, Control of Common) names this product by name: "Banvel, Clarity, Grazon P+D, GrazonNext HL, metsulfuron 60 DF, PastureGard HL, Remedy Ultra, Surmount, Tordon 22K and Weedmaster will kill all clover." That matters because clover is deliberately maintained in most grass pastures for nitrogen and forage quality, so on a clover paddock this is a spot-treatment product rather than a broadcast one. Recorded here as well as in the article because a reader can land on the product page first.

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.
