Flea beetles: At-risk crops

Canola fields at greatest risk from flea beetles – therefore fields most likely to need a spray – tend to be those seeded early and that went through a long stretch of slow growth.

Flea beetles damage canola by feeding on stems, cotyledons and young true leaves. Please read updated articles on flea beetles, including:

• Canola Encyclopedia chapter on flea beetles – which describes the insect and provides management tips.
• How to assess leaf area loss from flea beetles
• How to make the flea beetle spray decision
