Fluazifop vs Clethodim: Same Group, Different Labels
Both kill grass and spare broadleaves, and both are Group 1 — so swapping them is not rotation. What separates them is which sites their labels allow.

La versión agrícola de los mata-gramíneas para parcelas de fauna, en galón — el mismo cletodim, a una fracción del costo por acre tratado.
Si ya ha determinado que lo que necesita es cletodim, este es el tamaño y el precio que tienen sentido cuando la superficie supera una parcela pequeña. Es el mismo activo que las pintas de marca para parcelas de fauna, a 2 libras por galón, y el costo por acre no es comparable — el sobreprecio del envasado para parcelas es sustancial. Se gana un 4.6 sobre 266 valoraciones. Las contrapartidas son las de cualquier concentrado agrícola. Un galón es mucho herbicida y no mejora almacenado, así que esta es una compra para quien trata acres cada año y no una parcela una vez. La etiqueta es agrícola, lo que significa que la lista de cultivos, las dosis y cualquier intervalo de pastoreo o cosecha están declarados para cultivos y no para una parcela de fauna — léalos en lugar de suponer que una dosis de parcela se traslada. Y el requisito de coadyuvante sigue vigente: la mayoría de las etiquetas de cletodim quieren un coadyuvante oleoso, y ahí es donde se pierden los resultados.

Etiqueta leída en la base de datos de la EPA
EPA Reg. No. 42750-72
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. Registered as 'Clethodim 2E' to Albaugh (company 42750); AgriStar is Albaugh's brand. Clethodim 26.4%, and the label states it contains 2.0 lbs clethodim per gallon. STATE RESTRICTION found on the label: 'Application on Long Island, New York, is restricted to no more than 16 fl. oz./A of Clethodim 2E (0.25 lb ai/A)' — recorded as a New York state_note. A separate '(NOT FOR USE IN CALIFORNIA)' marking appears against one reduced-rate non-ionic surfactant direction, and the label carries an editor's note that the registrant may add or remove that state prohibition statement at will — so it is NOT a blanket California prohibition and we do not record it as one.
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: 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: 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
⚖️ Label restriction: application on Long Island is limited to no more than 16 fl. oz. per acre (0.25 lb ai/acre) of this product. If your plot or pasture is on Long Island, that ceiling is lower than the general rate and it is a label requirement rather than guidance.
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 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

Weed Control
Both kill grass and spare broadleaves, and both are Group 1 — so swapping them is not rotation. What separates them is which sites their labels allow.

Weed Control
Clover is a broadleaf, so broadleaf herbicide kills it. Three chemistries are selective enough not to — and the pre-plant kill is the one that matters most.

Lawn Care Guides
Microclover fixes its own nitrogen and feeds bees. It also ends whole-lawn broadleaf spraying forever, and dies back in winter. Extension seeding rates inside.

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 on canola: no herbicide controls wild radish or wild mustard in it. In a turnip or rape plot the worst weeds share the crop's own family.
