Black bindweed or climbing buckwheat (Fallopia convolvulus) is an annual herb with twining stems to 1 m long. Cotyledons are narrow-clubbed with rounded tips. Arrow-shaped leaves are hairless to slightly ‘mealy’ with a prominent mid-vein. The leaf margin has small, shallow, rounded ‘teeth’. Flowers are greenish white and the seed is dull black and tri-angled.

Factors that make black bindweed a major weed:

  • Is competitive in crops
  • Produces a large number of seeds
  • The twining habit of black bindweed causes problems of blockages in tillage equipment and contamination in grain samples
  • Is tolerant of many herbicides, particularly once it has more than two true leaves
  • Resistance to Group B herbicides was first recorded in 1993

Further detail about this weed including integrated weed management tactics that could be considered when developing a management plan can be found in the section on problem weeds in the Integrated Weed Management Manual.
