Apple fruit diseases can cause significant losses in yield and quality. Often, these diseases go unnoticed until just prior to harvest, during harvest, or after fruit has been stored. Although there are no curative treatments for infected fruit, many diseases can be prevented with cultural practices and (optional) fungicides. Accurate diagnosis, however, is critical to determine the best management practices and to prevent future losses.
Fruit Diseases of Apple (formerly, Apple Fruit Diseases Appearing at Harvest) is a newly revised publication intended to aid in the identification of common apple fruit diseases occurring in Kentucky. Symptom descriptions and color images, as well as causes, are included. Resources at the end of the publication point readers to more detailed information on fruit diseases and their management.
Fruit Rots of Apple (PPFS-FR-T-02) is available online.
