Shattercane is persistent in row crops throughout the US, and its spread through rhizomes makes it difficult to control. An integrated approach using prevention, cultural, chemical, and mechanical practices should be used to manage it effectively.

  • Save money and time on management by preventing the entry of shattercane to the field – prevention can be achieved by keeping equipment away from weed patches, and controlling small patches along fencerows and borders. Harvest infested fields last and thoroughly clean contaminated equipment.
  • Include rotations of small grains & alfalfa to compete with early season weed emergence
  • Plow in the fall or early spring to expose rhizomes to killing temperatures
  • Destroy rhizomes by disking several times before planting
  • Apply effective herbicide sites of action when plants are actively growing
  • Integrate multiple herbicide sites of action and do not rely on Group 2 (ALS) herbicides in areas where ALS-resistant populations are present (below)

Herbicide resistant populations:

  • Group 2

Locations of resistant populations:

Illinois, Indiana, Iowa, Kansas, Nebraska, Ohio, Pennsylvania, Virginia
