Rosy apple aphid management in organic fruit production

Rosy apple aphid (Dysaphis plantaginea) causes up to 95% yield loss in organic orchards through bud damage and honeydew-induced sooty mould. Management relies on preventive practices—balanced nitrogen use, pruning infested shoots, and enhancing biodiversity with flower strips and hedges—alongside targeted Neem-based sprays at 'tight cluster-pink' and post-bloom stages. Key natural enemies include coccinellid, chrysopid, aphid-midge, and syrphid larvae. Monitoring from pink bud to 10 mm fruit size ensures timely intervention. Developed by Laimburg Research Centre (2022), the tool supports integrated pest management in organic fruit systems and is available in English (USA), German (Switzerland), Italian, and Polish via Organic Farm Knowledge and Biofruitnet platforms.
