Weeds in Canola

Broad weed resources are outlined in the Agronomists Toolkit.

Weed competition

Weed competition

  • Weeds can compete with the growing canola crop for nutrients, water, space, and sunlight

Damage

  • If weeds are resistant to herbicides, prolific, or invasive, the yield penalty can be large

Management

Application of herbicides, integrated weed management, and cultural practices can all contribute to the successful management of weed populations.
