Field Bindweed

In 1937 Field Bindweed was the first weed to be declared noxious in the state of Kansas. It is an aggressive, low growing, perennial vine that spreads by rhizomes and seeds. The extensive root system can grow to 30 feet deep. Found almost anywhere, it competes with native and agricultural plants.

Appearance

  • Stems are prostrate, 1 to 4 feet long.
  • Leaves are more or less arrowhead-shaped.
  • Flowers are bell- or trumpet-shaped, white to pinkish, approximately 1 inch in diameter, usually appearing from late June to frost.
  • Seeds can remain viable for up to 50 years!

Control

Control of bindweed for cropland is competitive cropping and/or appropriate and timely cultivation. In non-cropland control is: cultivation and chemical herbicides. There are numerous herbicides approved effective for control of field bindweed with the following the more frequently used:

Treatment

  • 2,4-D Amine plus Dicamba
  • 2,4-D plus Picloram
  • Glyphosate, alone or in combination, is popular but care must be used in grassland areas

The use of a polymer type disposition aid may enhance control. Thorough coverage is essential for good control.

Recommended herbicides are available at the Pratt County Noxious Weed Department on a cost-share basis.
