""Both cutworms and flea beetles are generally early season pests... as soon as our seedlings start to emerge... that's generally when we have to deal with both.""
""Flea beetle damage is easier to spot through the characteristic 'shot hole' feeding on cotyledons and early leaves, with an established action threshold of 25 per cent leaf area loss.""
""We really don't have good ways to predict them... it's really based off of kind of the grower and the agronomist experience in that region.""
""Regular, boots-on-the-ground scouting remains the most reliable way to protect yield potential during those critical early growth stages.""
Canola growers face early-season threats from cutworms and flea beetles as seedlings emerge. Flea beetles are widespread and cause visible damage, while cutworms are patchy and harder to detect. Scouting strategies differ, with flea beetle damage identifiable through leaf loss, while cutworms require more investigation. Management includes neonicotinoid seed treatments for flea beetles and reactive measures for cutworms based on field history. Experience plays a crucial role in predicting pest pressure, emphasizing the importance of regular field scouting to protect yield potential.
