Flea beetle control goes outside the box at Ag in Motion

Ag in Motion 2025 is live; farmers can check out experimental trials like this one, playing with trap crops and natural repellents for flea beetles in canola

The stops at the 2025 Ag in Motion farm show feature an entomologist experimenting with trap crops and marigolds as concepts to control flea beetles.



Farmers are fighting their annual battle against flea beetles in their canola crop in 2025.

Breaks of two to three years between canola crops is considered sufficient to reduce crop disease severity.

Good agronomy urged under uncertain canola market

With tariffs and trade wars looming, Canadian canola growers are urged to eke out every bit of efficiency in their 2025 canola production
