Blackberries are a favored fruit grown for both home and commercial production in Kentucky. A significant challenge, however, is the presence of several fungal diseases that require careful cultivar selection and management during the growing season. Blackberry rosette, also known as double blossom, is one of these diseases.
Blackberry Rosette (Double Blossom) (PPFS-FR-S-03) is available online.
