Vendido como mata-matorral y etiquetado como herbicida de césped. El único sitio de la etiqueta es poa perenne, ryegrass perenne y festuca alta — y la hiedra terrestre y la violeta silvestre están ambas en su lista de malezas.
Lea la etiqueta en lugar del anuncio, porque en este producto no coinciden. El anuncio del mercado lo vende para plantas leñosas, enredaderas y matorral en zonas no agrícolas. La etiqueta aprobada por la EPA (81927-11-7401) declara un solo sitio: césped ornamental de poa perenne, ryegrass perenne y festuca alta, incluidos campos de tepe, césped comercial y campos de golf. Su dosis de aplicación general es de 3/8 a 3/4 de onza líquida por cada 1,000 pies cuadrados, y su tabla de malezas es una tabla de malezas de césped — hiedra terrestre, violeta silvestre, trébol, oxalis, medicago negro, cardo canadiense y cardo borriquero, acedera crespa, milenrama. No hay sección de matorral ni figura la hiedra venenosa. Así que es una opción genuina para las dos malezas con las que más batallan los dueños de céspedes de estación fría, la hiedra terrestre y la violeta silvestre, y es la compra equivocada para zarzas o un tocón cortado por mucho que diga el anuncio. Quedan dos advertencias reales. Es un ÉSTER, no la sal amina que usan la mayoría de los productos de césped: los ésteres penetran mejor y son más volátiles, así que las indicaciones de temperatura y deriva de la etiqueta no son texto de relleno. Y la lista de sitios es excluyente — la etiqueta dice no usar en otras especies de césped salvo que se pueda tolerar el daño, lo que descarta los céspedes de bermuda, zoysia, San Agustín y centipede.

CORRECTED 2026-08-02 after reading the label. This record previously described it as a non-crop brush herbicide for brambles, multiflora rose, honeysuckle and cut stumps, and stated it was 'not a lawn product' — all of that came from the Amazon listing title, and the label contradicts every part of it. The label's single site is perennial bluegrass / perennial ryegrass / tall fescue ornamental turf; Table 2 is a lawn weed table containing Ground Ivy and Wild Violet; there is no brush section and poison ivy is absent. brush-and-woody-plant-control.mdx carried the same wrong claim and was corrected in the same pass. This is the clearest example so far of why label_url exists.
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.
Contrastado con la presión real de enfermedades, malezas y plagas de cada estado.
Ventana de aplicación: April–May and September, and check every label against centipede before it leaves the shelf
Ventana de aplicación: June through July, inside the same short window everything else happens in. There is no autumn second chance
Ventana de aplicación: March–May and during monsoon flushes; Celsius-type products handle 100°F+ windows
Ventana de aplicación: Bounded by the label's temperature ceiling rather than the calendar — spring treatments finish before the June heat arrives, and nothing selective goes down again until September cools off
Ventana de aplicación: March–May while weeds are young; avoid spraying drought-stressed turf in summer
Ventana de aplicación: May–June and September; high-altitude sun makes stressed turf easy to injure, so spot-treat rather than blanket-spray
Ventana de aplicación: Broadleaf sprays in May–June and again in September, when the weeds are moving sugars to the roots; skip July and August, when a stressed cool-season lawn takes the injury and the weed does not
Ventana de aplicación: April to late May, then September into October. Skip July and August entirely: this is the transition zone, and a stressed tall fescue lawn takes the injury the weed shrugs off
Ventana de aplicación: April to early June and September–October; avoid mid-summer sprays on stressed turf
Ventana de aplicación: Year-round where the turf is actively growing, which is most of the time; the constraint is heat and drought stress on the leeward side rather than a dormant season
Ventana de aplicación: Late April into June, then September into October; skip the July and early August heat, which is also when UI's own fertilizer schedule goes quiet
Ventana de aplicación: May–June and September; fall beats creeping charlie best
Ventana de aplicación: October is the most effective month for broadleaf weeds; never apply above 80°F or to drought-stressed turf
Ventana de aplicación: October, and October is most of it — but check the wind and the date against what is happening in the fields, because early-summer growth-regulator drift is a real seasonal risk here and your own spray carries the same way
Ventana de aplicación: April into May and again in September–October; avoid July and August, when a tall fescue lawn here is already at its limit
Ventana de aplicación: April–May and September–October; autumn is the knockout window for the wild garlic that defines a Kentucky winter lawn
Ventana de aplicación: June, then a narrow late-August to mid-September window. Maine's usable autumn is the shortest in New England
Ventana de aplicación: April–May and September–October; autumn is the knockout window for the ground ivy and violet the Piedmont is full of
Ventana de aplicación: A narrow autumn is the real window here: late September into October, after the summer heat and before New England's early frost closes the season
Ventana de aplicación: May–June and September; autumn is the stronger window for perennial broadleaf weeds
Ventana de aplicación: Late May–June and September; autumn is the stronger window for perennial broadleaf weeds
Ventana de aplicación: April–May and September–October; skip summer sprays on drought-stressed fescue
Ventana de aplicación: June, then late August into September. In a sub-100-day valley there is no third chance
Ventana de aplicación: Late spring and again from late August through September, when perennial broadleaf weeds are moving reserves to the root
Ventana de aplicación: March–April and October in the south; May and September in the north
Ventana de aplicación: Late May into June, then late August through September. The autumn window closes earlier here than anywhere else in southern New England
Ventana de aplicación: May and September–October; autumn is the knockout window for perennial broadleaf weeds
Ventana de aplicación: Spring and early autumn; in the south skip the June heat entirely, and in the north the usable autumn window closes by early October
Ventana de aplicación: May and September–October; autumn is the knockout window for perennial broadleaf weeds
Ventana de aplicación: April–May and September–October; avoid spraying heat-stressed fescue in July–August
Ventana de aplicación: Early to mid-June, then late August into early September. There is no third opportunity
Ventana de aplicación: May–June and September; fall applications hit dandelion taproots hardest
Ventana de aplicación: Judged by wind before season: sustained wind is Oklahoma's normal condition, so the usable spray days are calm mornings in April, May and September rather than whole months
Ventana de aplicación: March–May and September–October; the long mild shoulder seasons give more usable spray days than most states get
Ventana de aplicación: May and September — fall is the knockout window for perennial broadleaf weeds
Ventana de aplicación: Broadleaf work in May–June and again in September; the September pass is the one that holds, because the weed is moving reserves down
Ventana de aplicación: April–May and September–October, and never above 90°F — centipedegrass is sensitive to 2,4-D both at spring green-up and in summer heat
Ventana de aplicación: Early to mid-June, then late August into September, which is the pass that actually holds on perennial broadleaf weeds
Ventana de aplicación: April–May and September–October; skip sprays on drought-stressed summer fescue
Ventana de aplicación: April–early June and September–October; avoid herbicides above 90°F
Ventana de aplicación: May and September, avoiding the intense midsummer heat on the label
Ventana de aplicación: Late May through June, then a short late-August to mid-September window. Vermont's autumn window is the narrowest in New England
Ventana de aplicación: April–May and September–October; skip sprays on heat-stressed fescue in July and August
Ventana de aplicación: April–May and September–October; WSU caps applications at 80°F, stricter than the 85–90°F ceilings used elsewhere
Ventana de aplicación: April into May and again in September–October. Skip July and August: this is transition-zone country and a heat-stressed tall fescue lawn absorbs the injury the weed does not
Ventana de aplicación: Early to mid-fall is the favourable window for dandelion and other perennial broadleaf weeds
Ventana de aplicación: June, then late August into September. UW's own framing is useful: a slow-release application covers a 90 to 100 day growing season, which is roughly the entire Wyoming season

Weed Control
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.

Weed Control
Both bottles say triclopyr. The words after it decide whether the spray stays where you put it — MSU measured ester drift injury at 50, amine under 20.

Weed Control
Virginia Tech: tall fescue can completely kill bermudagrass at a 4-inch mowing height with no herbicide. Mow lower and no product will save you.

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
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
Clover spreads where nitrogen is short — it makes its own. Feed the turf and it recedes. If you still want it out, four actives work and one popular one is absent.

Weed Control
Creeping Charlie and wild violet shrug off standard three-way weed killer for two different reasons. Both answer to triclopyr — and to October, not spring.
