|Scientific Name||Convolvulus arvensis|
|Common Names||English: Field bindweed; German: Ackerwinde; French: Liseron des champs; Spanish: Correhuela, campanilla menor|
|Description||Perennial weed with deep taproot and numerous horizontal root stolons covered with buds, found in warmer to moderate regions.|
Older leaves saggital, infindibulate white to purple flowers.
Long-petiolated, square to kidney-shaped, usually with a slight indentation at the apex, midrib and veins visible.
Hairless, prostrate or sinistrorse, glabrous to pubescent, 6-angled.
Saggital, lobed at the base, 20 mm (80.78 inch) long petiole, blade glabrous or pubescent, rounded at the apex.
Corolla funnelform, white or tinged with pink. Flowers either single or in loose cymes of up to 3 flowers.
Glabrous 4-valved capsule, +/-6 mm ( +/-0.23 inch) long.
Germination occurs all-year-round.
Low fruit setting.
Viability Of Seeds
Vegetative, sometimes by seed, 500 seeds/plant.
Waste ground, disturbed sites, roadsides, railroads.
Loose, warm and deep loam soil, lime-loving.
Additional Crop Information
Also widespread in areas with open vegetation.
C. arvensis became a major weed in almost all crops. It climbs up the stems of the crops and strongly competes for light and water and interferes with combine harvesting (picking of berry fruits, combining). The plants build very deep roots and many, up to 2 m (78.74 inch) long rhizomes. Single plants can spread widely in the field and infest great areas.
Reduced tillage practices increase the problem of field bindweed, short parts of the rhizomes can regrow.
Integrated Crop Management
Ploughing and repeated stubble cultivation suppresses field bindweed.
