Integrated carrot fly protection through agroecological strategies

This article details agroecological strategies for managing carrot fly (*Psila rosae*) in northwestern France since 2020. It covers integrated pest management approaches, including resistant carrot varieties with reduced volatile emissions and higher chlorogenic acid, companion planting (coriander, savory), cover crops, soil tillage, and visual/olfactory deterrents. Research projects like Apiaces (2021–2023), RePulse (CASDAR-funded), and APACES (EU/Normandy-funded) assess effectiveness in organic systems across Brittany, Normandy, and Pays de Loire. Trials show coriander reduces fly numbers by 50% compared to controls. Varietal selection (e.g., Norfolk for yield, Polydor for appearance) supports resistance. Ongoing work aims to finalize sustainable, low-pesticide strategies by 2023, balancing profitability and ecological impact.
