2,4-D amina puro a precio de concentrado — el activo base para hoja ancha que hay detrás de la mayoría de los productos de tres vías, sin los otros dos.
Si ya sabe que lo que necesita es 2,4-D, comprarlo por separado sale mucho más barato que comprarlo dentro de una mezcla de tres vías de marca, y esta es la versión con el mayor cuerpo de opiniones de usuarios de la plataforma, con más de ocho mil valoraciones. La sal amina es la formulación que se usa en césped y pastizal, frente a los concentrados éster que se venden para matorral en zonas no agrícolas. Donde se gana su sitio es en la amplitud de sitios: el 2,4-D está etiquetado para céspedes, pastizales y situaciones de tipo cereal, lo que lo convierte en el frasco al que más veces va a echar mano el dueño de una finca. Dos límites que conviene decir con claridad. Es un herbicida de hoja ancha, así que no hace nada contra malezas gramíneas ni contra los coquillos — eso exige una química completamente distinta. Y sobre las dos malezas por las que más se compra, las listas cortas de extensión no lo nombran: ni Penn State ni MSU incluyen el 2,4-D entre los activos eficaces contra el trébol, y la hiedra terrestre y la violeta silvestre responden al triclopir. Lea la lista de objetivos en lugar de suponer que un producto de hoja ancha cubre toda hoja ancha.

Etiqueta leída en el PDF del titular del registro
EPA Reg. No. 48273-4-829
Leímos la etiqueta impresa publicada por la empresa titular del registro. La EPA no aloja un PDF de esta, así que es el mejor texto disponible.
Label read 2026-08-02 (registrant's own PDF, EPA Est. No. 829-FL-1). 2,4-D dimethylamine salt, 46.8%, acid equivalent 38.4% = 3.8 lb/gal. Sites on the front panel: pastures and rangeland, lawns, golf courses, cemeteries, parks and similar ornamental turf, fences, ditchbanks, roadsides, industrial sites. A separate SMALL GRAINS section covers wheat, barley, oats and rye and is the basis of weed-control-in-cereal-food-plots: it opens 'Not underseeded with a Legume crop', gives 1 1/3 to 2 pints/acre for barley, wheat and rye but only 1/2 to 1 pint for OATS, times the application at 'full tiller stage (usually 4 to 8 inches tall)', and bars application before tillering or from early boot to milk stage. Season caps: one post-emergence application per crop cycle, max 2 1/2 pints/acre per application, 3 2/3 pints/acre per crop cycle. Grazing: do not graze or feed treated forage within 2 weeks; do not use treated straw for livestock feed.
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: June through July, inside the same short window everything else happens in. There is no autumn second chance
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: 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: 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: 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: 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: 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

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
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.

Weed Control
A cereal plot reverses every rule from a clover plot. 2,4-D goes on-label, clethodim kills the crop, and one clause about legumes rules out most mixed plots.

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

Weed Control
Killing dandelions without killing grass comes down to the taproot: the selective herbicides that reach it, and the month they actually work.
