Flea Beetle Management
- Seed Treatment: all canola is treated with a neonicotinoid treatment for flea beetle protection. Additional options are available for enhanced protection.
- Flea beetle feeding still occurs when seed treatments are utilized, as insecticide ingestion is required to achieve flea beetle control.
- Use best agronomic practices to promote a healthy crop. Higher plant populations can limit the amount of damage.
- Strong early vigour can limit the amount of flea beetle damage (% defoliation) per plant and help avoid breaching the damage threshold where a foliar insecticide is required.
