Field Bindweed (Convolvulus arvensis): Identification & Selective Herbicide Matrix
Quick Agronomic Summary
Quinclorac (Drive XLR8) or 2,4-D + Dicamba combinations deliver strong systemic control of Bindweed roots.
- Diagnostic Marker 1: Arrowhead-shaped alternate leaves with blunt lobes at the base
- Diagnostic Marker 2: Twining, vine-like climbing stems that wrap tightly around grass blades
- Diagnostic Marker 3: Funnel-shaped white to pink morning-glory-like flowers on long stalks
What is the best herbicide for Field Bindweed in lawns?
Quinclorac (Drive XLR8) or 2,4-D + Dicamba combinations deliver strong systemic control of Bindweed roots.
Field bindweed has deep roots penetrating up to 20 feet deep. Quinclorac translocates down the extensive root network.
When to treat Field Bindweed?
Spray in early fall or during full bloom in mid-summer when roots are actively storing nutrients.
Do not pull stems by hand, as root fragments regenerate new shoots.

| 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 |
| 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 |
