How to spot it
Apple scab is the most common apple disease in humid areas. On leaves and fruit you see olive‑green to black, rough spots; the fruit corks and splits open. They remain mostly edible in taste, but look unsightly and store poorly.
Prevention
Plant scab‑resistant varieties such as Topaz, Florina, or Rewena, that is the most effective protection. Prune the crown light and airy, so the leaves dry quickly, and remove the fallen leaves in autumn, where the fungus overwinters.
