Ontario flea beetles more aggressive this year

June 18, 2013, Ontario – A specialist with Ontario's Ministry of Agriculture says there are a number of flea beetle hot spots in canola fields across the province this spring.

Brian Hall says good overwintering conditions appear to have made the pests even more aggressive than usual this year.

If you're not watching your fields and scouting every few days, he says the flea beetles can quickly overrun a stand of canola. 

The guideline for taking action is if there is 25 per cent damage to the surface leaf area, but if you've got a thin stand of plants you might want to take action even earlier.
