Report on EDDMapSField Bindweed (Wild Morning-glory)
Convolvulus spp.
Overview
Field bindweed is one of the most persistent and difficult-to-control weeds in agricultural settings. Its deep root system (up to 20 feet) and long-lived seeds (up to 60 years) make eradication nearly impossible. It twines around crops and reduces yields significantly.
How to Identify
Perennial vine with arrow-shaped leaves. Small white to pink funnel-shaped flowers resembling morning glories. Twining growth habit. Spreads by both seeds and creeping roots.
Control Methods
Long-term integrated management is required. Repeated herbicide treatments over many years. Competitive cropping can help suppress populations.
Herbicide Recommendations
Picloram, 2,4-D, or dicamba. Multiple treatments over many years are required. No single treatment is effective.
⚠️ Always read and follow pesticide label directions. Contact your county weed superintendent for site-specific recommendations. Permits may be required near water.
