Practical Weed Science for the Field Scout: Corn and Soybean
Bindweed, field (Convolvulus arvensis)
Perennial broadleaf
A perennial trailing or climbing vine with white trumpet-shaped flowers that may reach 3-1/3 feet in length. Field bindweed is primarily a weed of nurseries, agronomic crops, and fencerows and can be found throughout the United States. Cotyledons are square-shaped and dark green with relatively prominent white to light green veins. Leaves are triangular in outline with leaf bases that are lobed and point outward. Leaves and stems may be with or without hairs. Field bindweed is often confused with wild buckwheat. However, wild buckwheat has inward-pointing bases and an ocrea at the base of each petiole.
