What to look for

    Plant

Where did it come from?

  • Fasciation has several possible causes, including hormonal, genetic, bacterial, fungal, viral and environmental.
  • Fasciation is observed more often in some canola varieties than in others.

Management strategies

  • No treatment is recommended as this condition is relatively rare and is thought to cause only minor yield effects.
  • It is not carried between seasons in seed.
