Canola Striped Flea Beetle has now been detected at the North Central Research Extension Center sticky traps. This is an indicator that scouting should begin as crops continue to emerge. This should be done regularly until canola reaches the 4th to 6th leaf stage. Most damage is likely to occur during the first two weeks following crop emergence. For foliar insecticide applications, the action threshold arrives when 20-25% defoliation has occurred to plants younger than the 4th leaf stage. For more information on the Canola Flea Beetle, please refer to the NDSU Extension “Integrated Pest Management of Flea Beetles in Canola” publication (E1234).
