Flea beetles and cutworms are major pests that can significantly damage canola crops, especially during early growth stages. Flea beetles feed on the leaves and stems of young canola plants, while cutworms cut off seedlings at the soil surface. Both pests can cause severe damage, leading to reduced plant stands and delayed crop maturity.

Flea beetle populations, particularly striped flea beetles, are not decreasing. In fact, they are becoming more prevalent across the Prairies. Striped flea beetles have been noted to increase in areas like northern Saskatchewan and Manitoba. Cutworms are also on the rise, with reports of significant infestations across Western Canada.

These pests can delay maturity and reduce yields, making effective control essential. Flea beetles can cause up to 10% yield loss even with insecticide treatments. Cutworms can cause patchy damage in fields, leading to significant economic losses if not managed properly.

Solutions:

1. Use Buteo for Improved Control Over Striped Flea Beetles:

• Buteo has shown better control of striped flea beetles compared to other treatments like Prosper or Helix Vibrance. This can help protect young canola plants during their most vulnerable stages.

2. Apply Lumiderm/Lumiposa for Excellent Control of Cutworms:

• Lumiderm and Lumiposa are effective seed treatments for controlling cutworms. These treatments help protect seedlings from being cut off at the soil surface, ensuring better plant stands and healthier crops.

3. Avoid Base Treatments Like Helix Vibrance and Prosper:

• With increasing flea beetle populations, base treatments like Helix Extra and Prosper are less effective. Opting for more advanced treatments like Buteo can provide better protection and improve overall crop health.

By choosing the right seed treatments, farmers can effectively manage flea beetles and cutworms, ensuring healthier canola crops and better yields. Regular scouting and timely application of treatments are key to minimizing the impact of these pests.
