How to Kill White Dutch Clover in Centipedegrass Without Hurting Your Lawn
Direct Agronomic Answer
To selectively kill White Dutch Clover in Centipedegrass without damaging your turf, apply Tenacity (Mesotrione 40%), Celsius WG (Thiencarbazone-methyl 8.7%, Iodosulfuron-methyl-sodium 1.9%, Dicamba 57.4%) when air temperatures are between 55°F and 85°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.
1. Labeled Safe Herbicides That Kill White Dutch Clover in Centipedegrass
| Recommended Product | Active Ingredient & Group | Application Temp (°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 |
| 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 |
2. What NOT to Spray on Centipedegrass When Treating White Dutch Clover
Warning: Common White Dutch Clover Killers That Damage Centipedegrass
Many retail herbicides advertised for White Dutch Clover are formulated for different turf zones and will severely injure Centipedegrass:
- AVOID Drive XLR8 (Quinclorac 18.92%): Rated 'avoid' on Centipedegrass — high risk of turf phytotoxicity or stunting.
- AVOID SpeedZone Lawn Weed Killer (2,4-D 28.57%, Mecoprop-p 5.88%, Dicamba 1.71%, Carfentrazone-ethyl 0.62%): Rated 'avoid' on Centipedegrass — high risk of turf phytotoxicity or stunting.
- AVOID TZone SE (Triclopyr 7.72%, 2,4-D 29.36%, Dicamba 2.22%, Sulfentrazone 0.66%): Rated 'avoid' on Centipedegrass — high risk of turf phytotoxicity or stunting.
3. Optimal Seasonal Timing & Temperature Thresholds
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.
4. Diagnostic Checklist: Confirm It Is White Dutch Clover Before Spraying
- Trifoliate leaves composed of three oval leaflets, each marked with a pale white crescent watermark
- Creeping above-ground stolons that root firmly at every node across nitrogen-deficient soil
- Globe-shaped white to pinkish-white flower heads visited heavily by honeybees from May to September
