Can You Mix Herbicides in One Tank? The Order Matters
NDSU: most broadleaf herbicides tank mixed with grass herbicides reduce grass control. The fix is sequence — grass herbicide one day before, or seven days after.

Clethodim kills grasses and leaves broadleaf plants standing — the mirror image of every lawn herbicide, and what a clover plot actually needs.
Our Verdict
The reverse of everything else on this site. Lawn herbicides spare grass and kill broadleaves; clethodim spares broadleaves and kills grasses, which is what you need when the crop is clover, alfalfa or brassica and the weeds are grasses. It is an ACCase inhibitor and it is genuinely selective rather than rate-dependent, so a clover plot survives a rate that removes crabgrass, foxtail and volunteer cereal. Packaged and priced for food plots at a pint, with 898 Amazon ratings, which is a substantial evidence base for a specialist product. Two things to get right. Most clethodim labels require an oil-based adjuvant rather than a plain nonionic surfactant, and skipping it is the usual cause of a disappointing result — read the adjuvant line before you mix. And it does nothing to broadleaf weeds, so a plot with both grass and broadleaf problems needs this plus a legume-safe broadleaf product, not this alone. The generic clethodim concentrate is cheaper per acre if you are treating more than a small plot.
✅ Pros
- Selective on grasses while sparing clover, alfalfa and brassicas
- 898 Amazon ratings — strong validation for a specialist food plot product
- Pint size matches a small plot rather than committing you to a gallon
- Different chemistry from anything else in a lawn owner's shed, so no resistance overlap
⚠️ Cons
- No activity on broadleaf weeds — you need a second product for those
- Most clethodim labels require an oil adjuvant, not a plain surfactant, and omitting it disappoints
- Significantly more expensive per unit of active than generic clethodim
- Food plot packaging carries a premium over the agricultural equivalent

Where our facts come from
Label read on the registrant's own PDF
EPA Reg. No. 228-729-81883
We read the printed label published by the company that holds the registration. EPA hosts no PDF for this one, so this is the best available text.
What we found when we read it
Label read 2026-08-05 from the Whitetail Institute's own published booklet, with the registration number independently confirmed on their SDS. EPA Reg. No. 228-729-81883 — three parts, a distributor version of 228-729 (Nufarm). Clethodim 12.6%, 0.97 lb clethodim per gallon, contains petroleum distillates. Signal word CAUTION, not a restricted-use pesticide. The restrictions that matter here are ENDANGERED-SPECIES geographic prohibitions rather than ordinary state rules, and they are unusually specific: use is prohibited where Solano Grass is known to exist — Solano County, California, in the vernal lakes area bounded by the Union Pacific Railroad and Hastings Road to the north, Highway 113 to the east, Highway 12 to the south and Travis Air Force Base to the west — and where Wild Rice is known to exist, in Hays County, Texas. Neither is a statewide ban; both are small mapped areas inside states we cover.
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.
Where This Product Matters
Matched against each state's actual disease, weed and pest pressure.
Alabama
Alabama hub →Crabgrass
Application window: April–May and September, and check every label against centipede before it leaves the shelf
Arizona
Arizona hub →Crabgrass
Application window: March–May and during monsoon flushes; Celsius-type products handle 100°F+ windows
Arkansas
Arkansas hub →Crabgrass
Application window: 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
California
California hub →Crabgrass
Application window: March–May while weeds are young; avoid spraying drought-stressed turf in summer
⚖️ This label carries an endangered-species prohibition in one mapped area of Solano County — the vernal lakes bounded by the Union Pacific Railroad and Hastings Road, Highway 113, Highway 12 and Travis Air Force Base — to protect Solano Grass. The rest of California is unaffected.
Colorado
Colorado hub →Crabgrass
Application window: May–June and September; high-altitude sun makes stressed turf easy to injure, so spot-treat rather than blanket-spray
Connecticut
Connecticut hub →Crabgrass
Application window: 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
Delaware
Delaware hub →Crabgrass
Application window: 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
Florida
Florida hub →Crabgrass
Application window: March–May and October–November; avoid applications above 85°F
Georgia
Georgia hub →Crabgrass
Application window: April to early June and September–October; avoid mid-summer sprays on stressed turf
Hawaii
Hawaii hub →Crabgrass
Application window: 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
Idaho
Idaho hub →Crabgrass in the warmer southern valleys
Application window: 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
Illinois
Illinois hub →Crabgrass
Application window: May–June and September; fall beats creeping charlie best
Indiana
Indiana hub →Crabgrass
Application window: October is the most effective month for broadleaf weeds; never apply above 80°F or to drought-stressed turf
Iowa
Iowa hub →Crabgrass
Application window: 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
Kansas
Kansas hub →Crabgrass
Application window: April into May and again in September–October; avoid July and August, when a tall fescue lawn here is already at its limit
Kentucky
Kentucky hub →Crabgrass
Application window: April–May and September–October; autumn is the knockout window for the wild garlic that defines a Kentucky winter lawn
Maine
Maine hub →Crabgrass (southern and coastal Maine more than the interior)
Application window: June, then a narrow late-August to mid-September window. Maine's usable autumn is the shortest in New England
Maryland
Maryland hub →Crabgrass
Application window: April–May and September–October; autumn is the knockout window for the ground ivy and violet the Piedmont is full of
Massachusetts
Massachusetts hub →Crabgrass
Application window: 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
Michigan
Michigan hub →Crabgrass
Application window: May–June and September; autumn is the stronger window for perennial broadleaf weeds
Minnesota
Minnesota hub →Crabgrass
Application window: Late May–June and September; autumn is the stronger window for perennial broadleaf weeds
Mississippi
Mississippi hub →Crabgrass
Application window: April–May and September, avoiding the midsummer heat restrictions on most labels
Missouri
Missouri hub →Crabgrass
Application window: April–May and September–October; skip summer sprays on drought-stressed fescue
Montana
Montana hub →Crabgrass and foxtail in the warmer valleys and in thin ground
Application window: June, then late August into September. In a sub-100-day valley there is no third chance
Nebraska
Nebraska hub →Crabgrass
Application window: Late spring and again from late August through September, when perennial broadleaf weeds are moving reserves to the root
Nevada
Nevada hub →Crabgrass
Application window: March–April and October in the south; May and September in the north
New Hampshire
New Hampshire hub →Crabgrass (heaviest in the south, thinning northward)
Application window: Late May into June, then late August through September. The autumn window closes earlier here than anywhere else in southern New England
New Jersey
New Jersey hub →Crabgrass
Application window: May and September–October; autumn is the knockout window for perennial broadleaf weeds
New Mexico
New Mexico hub →Crabgrass in irrigated turf
Application window: Spring and early autumn; in the south skip the June heat entirely, and in the north the usable autumn window closes by early October
New York
New York hub →Crabgrass
Application window: May and September–October; autumn is the knockout window for perennial broadleaf weeds
North Carolina
North Carolina hub →Crabgrass
Application window: April–May and September–October; avoid spraying heat-stressed fescue in July–August
North Dakota
North Dakota hub →Foxtail and barnyardgrass in thin or disturbed groundCrabgrass, real but a smaller problem than further south
Application window: Early to mid-June, then late August into early September. There is no third opportunity
Ohio
Ohio hub →Crabgrass
Application window: May–June and September; fall applications hit dandelion taproots hardest
Oklahoma
Oklahoma hub →CrabgrassSandbur (the western sandy-soil weed that standard crabgrass preventers do not list)
Application window: 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
Oregon
Oregon hub →Crabgrass (east side and hot summers only)
Application window: March–May and September–October; the long mild shoulder seasons give more usable spray days than most states get
Pennsylvania
Pennsylvania hub →Crabgrass
Application window: May and September — fall is the knockout window for perennial broadleaf weeds
Rhode Island
Rhode Island hub →Crabgrass
Application window: Broadleaf work in May–June and again in September; the September pass is the one that holds, because the weed is moving reserves down
South Carolina
South Carolina hub →Crabgrass
Application window: 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
South Dakota
South Dakota hub →Crabgrass and foxtail in thin or disturbed ground
Application window: Early to mid-June, then late August into September, which is the pass that actually holds on perennial broadleaf weeds
Tennessee
Tennessee hub →Dallisgrass (a perennial the quinclorac that clears crabgrass will not touch)Crabgrass
Application window: April–May and September–October; skip sprays on drought-stressed summer fescue
Texas
Texas hub →Crabgrass
Application window: April–early June and September–October; avoid herbicides above 90°F
⚖️ This label prohibits use in Hays County to protect Wild Rice. It is an endangered-species restriction on one county, not a statewide ban.
Utah
Utah hub →Crabgrass
Application window: May and September, avoiding the intense midsummer heat on the label
Vermont
Vermont hub →Crabgrass (a valley problem more than a hill-town one)
Application window: Late May through June, then a short late-August to mid-September window. Vermont's autumn window is the narrowest in New England
Virginia
Virginia hub →Crabgrass
Application window: April–May and September–October; skip sprays on heat-stressed fescue in July and August
West Virginia
West Virginia hub →Crabgrass
Application window: 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
Wisconsin
Wisconsin hub →Crabgrass
Application window: Early to mid-fall is the favourable window for dandelion and other perennial broadleaf weeds
