White Dutch Clover (Trifolium repens): Identification & Selective Herbicide Matrix
Quick Agronomic Summary
Triclopyr + Dicamba (TZone SE) in cool-season turf or Thiencarbazone + Dicamba (Celsius WG) in warm-season turf eliminates White Clover within 7 to 10 days when sprayed between 55°F and 80°F.
- Diagnostic Marker 1: Trifoliate leaves composed of three oval leaflets, each marked with a pale white crescent watermark
- Diagnostic Marker 2: Creeping above-ground stolons that root firmly at every node across nitrogen-deficient soil
- Diagnostic Marker 3: Globe-shaped white to pinkish-white flower heads visited heavily by honeybees from May to September
What herbicide kills White Clover in a lawn fastest?
Triclopyr + Dicamba (TZone SE) in cool-season turf or Thiencarbazone + Dicamba (Celsius WG) in warm-season turf eliminates White Clover within 7 to 10 days when sprayed between 55°F and 80°F.
2,4-D alone provides poor control on legumes and only curls White Clover leaves temporarily. Pyridine herbicides (Triclopyr) or benzoic acids (Dicamba) combined with Mesotrione disrupt stolon nodes completely. In St. Augustine and Centipede lawns, use Celsius WG or Hi-Yield Atrazine.
When should you spray White Clover to prevent lawn re-infestation?
Spray White Clover in mid-spring (55°F–75°F) before white flower heads open or in early autumn, and mow off any active blooms prior to spraying to protect foraging pollinators.
Because White Clover thrives in low-nitrogen soils by fixing atmospheric nitrogen via root nodules, maintaining an annual fertility program of 3 to 4 lbs of nitrogen per 1,000 sq ft allows dense turfgrass to crowd out new stolons naturally.
EPA-Registered Herbicides Labeled for White Dutch Clover
The table below compares all selective herbicides in our database that control White Dutch Clover, including active ingredient groups, application temperature limits (°F), and surfactant requirements.
| Brand Name & EPA Reg. | Active Ingredient & WSSA Group | Temp Window (°F) | Surfactant & Mixing Protocol | Where to Buy |
|---|---|---|---|---|
| Tenacity EPA Reg. 100-1267 |
Mesotrione 40% Group 27 (HPPD Inhibitor) |
55°F – 85°F Rainfast: 6h |
Always apply with Non-Ionic Surfactant (NIS) at 1 tsp (5 mL) per gallon of water for post-emergent applications. Causes temporary white bleaching on susceptible weeds and turf tips. | Check Price at DoMyOwn View on Amazon |
| Drive XLR8 EPA Reg. 7969-272 |
Quinclorac 18.92% Group 4 (Synthetic Auxin / Quinoline Carboxylic Acid) |
60°F – 85°F Rainfast: 1h |
Requires Methylated Seed Oil (MSO) surfactant at 1.5 tbsp (0.75 fl oz) per gallon of water for effective cuticle penetration on multi-tiller crabgrass. | Check Price at DoMyOwn View on Amazon |
| SpeedZone Lawn Weed Killer EPA Reg. 2217-833 |
2,4-D 28.57%, Mecoprop-p 5.88%, Dicamba 1.71%, Carfentrazone-ethyl 0.62% Group 4 + Group 14 (Synthetic Auxins + PPO Inhibitor) |
50°F – 85°F Rainfast: 3h |
Do NOT add surfactant. Adding NIS or MSO increases ester volatility and causes severe contact burn on desirable cool-season turf. | Check Price at DoMyOwn View on Amazon |
| TZone SE EPA Reg. 2217-920 |
Triclopyr 7.72%, 2,4-D 29.36%, Dicamba 2.22%, Sulfentrazone 0.66% Group 4 + Group 14 (Pyridine Auxin + Phenoxy + PPO Inhibitor) |
50°F – 80°F Rainfast: 3h |
Do NOT mix with surfactant when temperatures exceed 75°F. In cool spring or fall conditions (55°F–70°F), 0.5 tsp NIS per gallon improves waxy leaf penetration on Wild Violet. | Check Price at DoMyOwn View on Amazon |
| Celsius WG EPA Reg. 432-1507 |
Thiencarbazone-methyl 8.7%, Iodosulfuron-methyl-sodium 1.9%, Dicamba 57.4% Group 2 + Group 4 (ALS Inhibitors + Benzoic Acid Auxin) |
65°F – 95°F Rainfast: 4h |
Apply with Non-Ionic Surfactant (NIS) at 1 tsp per gallon of water. Specifically engineered not to stunt warm-season turf during summer heat up to 95°F. | Check Price at DoMyOwn View on Amazon |
| Hi-Yield Atrazine Weed Killer EPA Reg. 34911-15-7401 |
Atrazine 40.8% Group 5 (Photosystem II Inhibitor / Triazine) |
50°F – 85°F Rainfast: 6h |
Do NOT add surfactant when spraying actively growing St. Augustine or Centipede above 80°F to avoid foliar yellowing. Irrigate lightly within 48 hours for root uptake. | Check Price at DoMyOwn View on Amazon |
| Pylex Herbicide EPA Reg. 7969-327 |
Topramezone 29.7% Group 27 (HPPD Inhibitor / Pyrazolone) |
55°F – 85°F Rainfast: 1h |
Must be applied with Methylated Seed Oil (MSO) at 1 to 1.5 tsp per gallon of water. Tank-mixing with Triclopyr Ester reduces white bleaching and speeds up Bermudagrass and Goosegrass mortality. | Check Price at DoMyOwn View on Amazon |

How to Distinguish White Dutch Clover from Lookalike Weeds
| Lookalike Species | Key Botanical & Diagnostic Difference |
|---|---|
| Black Medic | Black Medic has a longer projecting stalk on the middle leaflet, no white V-shaped watermark, and small bright yellow hop-like flowers. |
| Yellow Woodsorrel (Oxalis) | Oxalis leaflets are distinctly heart-shaped with a sharp center crease and five-petaled yellow flowers, whereas White Clover leaflets are rounded ovals. |
