Field Bindweed Control for Turf

Field bindweed is a deep-rooted perennial vine that spreads by seed and an extensive underground root system. It is most common along turf edges, neglected areas, and disturbed sites.

How to Identify Field Bindweed

Arrow-shaped leaves alternate on twining stems, and white-to-pink funnel-shaped flowers resemble small morning glories. Roots are deep and brittle, and fragments can regenerate.

Why It Appears in Turf

Disturbed soil, open sunny borders, and incomplete digging favor spread. Long-lived seed and deep roots allow repeated emergence.

Make the Site Less Favorable

• Maintain the recommended mowing height and avoid scalping.
• Correct irrigation, drainage, compaction, fertility, or shade problems that thin desirable turf.
• Repair bare areas and use adapted turf cultivars to close openings where seedlings establish.

What University Research and Extension Guidance Says

University weed-management guidance treats field bindweed as a long-term suppression project. Repeated systemic treatment of actively growing foliage plus prevention of seed production is more realistic than a single rescue application.

Choosing a Turf Herbicide

Perennial weeds often regrow from stolons, rhizomes, tubers, bulbs, or deep roots. Select a product labeled for the desirable turf and target weed, treat actively growing plants, and plan the complete sequence of repeat applications or renovation steps allowed by the label.

Research and label note: University research may discuss treatments or timings that are not permitted on every turf species or use site. Research evidence does not expand a product label. Confirm the desirable turf species, use site, target weed, application timing, rate, adjuvant directions, and reseeding restrictions on the current label before use.
