Hi-Yield Grass Killer Postemergence Grass Herbicide, 8 oz — Reseña

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

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

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
