Triclopir en solitario, que es exactamente lo que los servicios de extensión nombran para las dos malezas que se encogen de hombros ante los productos corrientes de tres vías — y la razón para comprobar su tipo de césped antes de comprar.
Esta es la respuesta del estante doméstico a un problema concreto: la hiedra terrestre y la violeta silvestre sobreviven a los mata-malezas estándar de tres vías, y la guía de Penn State dice que los herbicidas que contienen triclopir dan el mejor control, solos o combinados con fluroxipir. La mayoría de los frascos de ese estante son 2,4-D más dicamba más MCPP y no llevan triclopir en absoluto. Este es triclopir y nada más, al 8% como sal de trietilamina — la forma amina, que es la que usan los productos de césped, en lugar de los concentrados éster que se venden para matorral en zonas no agrícolas y que dañarían un césped. La restricción es lo que hay que leer antes de comprar, y es grande: la etiqueta excluye bahiagrass, bermudagrass, centipedegrass, kikuyugrass y San Agustín. Eso descarta la mayoría de los céspedes del Sur. Figura como seguro sobre buffalograss, festucas, poa de Kentucky, ryegrass y zoysia, que es el conjunto de estación fría más la zoysia — y convenientemente el rango donde la hiedra terrestre es el peor problema de todos modos. Cuente con aplicar más de una vez: la guía de extensión para ambas malezas objetivo son aplicaciones repetidas a lo largo de una temporada y a menudo de varios años, programadas en otoño y no en primavera.

Etiqueta leída en la base de datos de la EPA
EPA Reg. No. 239-2491
Abrimos la etiqueta aceptada de este producto en el propio Pesticide Product Label System de la EPA — la fuente más sólida que existe sobre lo que un producto está registrado para hacer.
Full label read 2026-08-02 on EPA PPLS (accepted 2024-08-06). Registered product name is 'ORTHO BRUSH-B-GON BRUSH KILLER'; our product is one of its alternate brand names, listed as 'ORTHO CONCENTRATE WEED-B-GON CHICKWEED, CLOVER & OXALIS KILLER'. Triclopyr triethylamine salt 8% confirmed. THE GRASS LIST WE PUBLISH IS EXACTLY RIGHT and is now verified rather than asserted — the label reads 'Do not use on Bahiagrass, Bermudagrass, Centipedegrass, Kikuyugrass or St. Augustinegrass', and names Buffalograss, Fescues, Kentucky Bluegrass, Ryegrass and Zoysiagrass as tolerant. That list appears on 22 pages of this site, so verifying it was the point of reading this label. Ground ivy and wild violet appear throughout, as does poison ivy — one master label covering both the lawn use and the brush use, printed as separate brand booklets. Also on it: 'Do not use on or around edible feed or food crops or areas where grazing is allowed' — so this is not a pasture product despite the shared registration with a brush killer.
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.

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: March–May and October–November; avoid applications above 85°F
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: March–May and October–November; avoid applications above 85°F and never on drought-stressed St. Augustine
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, avoiding the midsummer heat restrictions on most labels
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
Getting rid of oxalis in a lawn takes two fixes. Penn State: pre-emergents stop it from seed but have no effect on plants emerging from rhizomes.

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
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.

Lawn Care Guides
Fall lawn care is the one season when doing more genuinely pays — for cool-season grass. On a warm-season lawn, autumn is mostly about stopping.

Product Reviews
