The onion maggot and seedcorn maggot present significant challenges for vegetable growers. While insecticide seed treatments are commonly utilized for maggot control, their effectiveness differs by region, and rising environmental concerns have prompted the search for safer alternatives. This study investigated alternatives to neonicotinoid seed treatments (thiamethoxam and imidacloprid) for controlling seedcorn maggot in onions, snap beans, dry beans, and sweet corn. As restrictions on neonicotinoids increase due to their effects on pollinators and beneficial insects, this research aims to identify effective and environmentally responsible pest control options. These findings will assist growers in making informed pest management decisions in the future.
