Apple scab management in organic pome fruit production

Apple scab, caused by Venturia inaequalis, is the primary fungal disease in organic pome fruit production, reducing yield and fruit quality. This guide outlines integrated management strategies for organic apple growers, including planting scab-resistant varieties like Story/Inored, Topaz, Opal, Ladina, and Santana. It emphasizes orchard design—aligning rows with prevailing winds, wide spacing, and regular pruning—to improve air circulation and reduce leaf moisture. Post-harvest practices such as mechanical tillage, vinasse application, and leaf vacuuming help reduce overwintering inoculum. The tool, published in 2022 by FÖKO (Germany) within the Biofruitnet project, is available in English (USA), German (Switzerland), Polish, and other languages via Organic Eprints. It supports biological disease control and sustainable pome fruit production.
