Apple scab (V. inaequalis) is the main disease in organic apple production. Availability of varieties is a major problem as only a few robust varieties are available on the market.
The researchers propose a list of currently well-known robust varieties that are suitable for large scale production. Current breeding of new cultivars is crucial for the future of organic growing, stay tuned.
Using robust cultivars reduces the need for external and high cost inputs, reduces the workload on farmers (less applications are needed) and enhances the sustainability of the fruit production. Practical recommendations.
