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.
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.

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.
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.

Product Reviews
Arkansas trials give a product, a rate and a month for each weed — and for horsenettle, three consecutive years. Look up the weed before you buy a bottle.

Weed Control
Penn State: a cane tip touching the ground roots and makes a new plant. Mowing takes three to six passes a season for over a year — or 8 to 10 goats per acre.

Weed Control
Alabama Extension: the large woody root cannot sprout. Kudzu regrows from root crowns at the soil surface — which is what you can actually reach and kill.

Weed Control
UGA: the toxin is not normally on the outside surface of intact leaves and stems. So the dangerous act is breaking the plant — which is what pulling does.

Weed Control
Grazing restrictions run from seven days to a year, and beef and dairy differ. UGA: without cultural practices, herbicide use will not be beneficial.

Weed Control
UGA: fresh red maple leaves are not toxic, wilted ones are. Most toxic plants are unpalatable — so the danger is created by running out of forage, not by the plant.
