Best Weed Puller: How Much Root Did You Actually Get?
UC IPM: a dandelion taproot runs 6 to 18 inches and a 1-inch fragment regrows. The tool decides how much root you get — the weed decides if that is enough.

La propia expresión de UC IPM para lo que hace esta categoría es retirar malezas individuales y sus raíces minimizando la alteración del suelo — lo contrario de lo que hace una garra que agarra la corona.
La herramienta que coincide con lo que la investigación dice realmente que exige el trabajo. UC IPM registra que la raíz pivotante del diente de león se encuentra sobre todo en las primeras 6 a 18 pulgadas y que secciones de raíz de tan solo una pulgada pueden generar una planta nueva, así que la cuestión nunca es el agarre, es la profundidad. Una hoja baja junto a la raíz y la corta o la levanta; una garra de cuatro puntas agarra cerca de la corona y se lleva lo que quedaba por encima de donde cerró. UC IPM nombra esta categoría directamente — cuchillos para diente de león y herramientas especializadas similares para retirar malezas individuales y sus raíces minimizando la alteración del suelo — y esa última parte importa más de lo que parece, porque WeedCUT registra que la alteración por excavar puede activar el banco de semillas existente. Un cuchillo abre una ranura; una garra abre un agujero. Es más lento que un extractor de pie y exige arrodillarse, que es un coste real en un césped lleno de dientes de león. Es la mejor herramienta en un parterre, en una grieta, contra un muro, y en cualquier raíz que de verdad piense seguir.

Correctamente sin registro ante la EPA
Los coadyuvantes, colorantes, dispositivos y productos de riesgo mínimo no son plaguicidas registrados, así que un número de registro vacío aquí es lo correcto y no una omisión.
Not a pesticide — nothing to register. Specifications recorded 2026-08-20 from the retailer listing: 7.25 in Japanese stainless blade, straight and serrated edges, model NJP650, Namibagata pattern. retailer_rating omitted — rendered in script and not read, consistent with the rest of the 2026-08-20 tool batch. The agronomic claims in this record are UC IPM's, quoted on our best weed puller page: taproot depth 6 to 18 in, 1 in root sections capable of generating new plants, and the dandelion-knife category description.
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: 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

UC IPM: a dandelion taproot runs 6 to 18 inches and a 1-inch fragment regrows. The tool decides how much root you get — the weed decides if that is enough.

Weed Control
Broadleaf plantain tells you something before you kill it — UMD lists dry, compacted soil and poor feeding as what favours it. Clemson's window is mid-autumn.

Weed Control
"Pet safe" is not a regulated claim, and most products sold under it kill grass as fast as weeds. The promise that is real: keep pets off until it dries.

Product Reviews
The organic weed killer that works on lawns is iron — it burns broadleaf weeds and moss in hours without harming grass. What it won't do: kill the roots.

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