Best Weed Killer for Lawns: Match It to the Weed

Uno de los muy pocos activos que cubre a la vez el coquillo amarillo y las malezas de hoja ancha — y actúa por contacto, lo que determina cómo hay que usarlo.
El bentazón ocupa una posición inusual: es activo sobre el coquillo amarillo y sobre una lista de hoja ancha, cosa que casi ningún otro producto accesible al propietario hace, y lo tolera una amplia gama de especies de césped. La trampa está en el modo de acción. El bentazón actúa por contacto en lugar de translocarse con fuerza, lo que tiene tres consecuencias que no se pueden esquivar. La cobertura debe ser minuciosa, porque el tejido no tocado es tejido no tratado. Funciona sobre coquillo joven y en crecimiento activo, y decepciona sobre un rodal maduro. Y como no se mueve bien hacia los tubérculos del coquillo, suprime en lugar de erradicar — para un problema de coquillo establecido el halosulfurón es la mejor herramienta, y el bentazón es la elección cuando además hay hoja ancha que resolver en la misma pasada. La etiqueta exige un surfactante para obtener resultados aceptables. Reservas prácticas: un galón a unos 82 dólares es volumen profesional para un propietario, y 37 valoraciones son una base de evidencia delgada frente a los productos de coquillo y hoja ancha que tiene al lado.

Etiqueta leída en la base de datos de la EPA
EPA Reg. No. 7969-326
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 2024-09-11). 'Basagran T&O Herbicide', EPA Reg. 7969-326, sodium salt of bentazon 44%, stated on the label as equivalent to 4 pounds per gallon bentazon. Noted as a MASTER LABEL, which means a specific retail jug may print a narrower site or weed list than the registration allows — check the booklet on the container against any rate here.
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: 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: 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: 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: 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: 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: 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: 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: 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: 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

Product Reviews
There is no best weed killer for lawns, only the right one for your weed: the seven chemistries that matter, what each kills, and the one that kills grass too.

Weed Control
Nutsedge ignores ordinary weed killer because it is a sedge. UC IPM: one pull does nothing — but pulling every 2 to 3 weeks drains the tuber underneath it.

Weed Control
Lawn weed identification in 60 seconds: the three families, the field checks that separate them, and why broadleaf products do nothing to a sedge.
