Numerous beneficial insects, including both predatory ground beetles and parasitic wasps and flies are often effective in suppressing cutworm populations below damaging levels. Therefore, unnecessary use of insecticides should be avoided. The list of products registered for control of cutworms in canola is limited compared to those for flea beetle control, leading to some confusion about which products are appropriate. As well, some applications are being made with less than recommended water volumes. Only apply products registered for cutworm control in canola using water volumes recommended by the manufacturer to ensure effective control is achieved. For more information, contact local retailers or product manufacturers. Always read and follow product labels prior to application.
