Last Year’s Small Fruit Diseases Equal This Year’s Disease Risk

Disease presence last year can indicate a risk for the same disease this year. Many pathogens overwinter in Kentucky on infected plant material or as pathogen survival structures. Poor sanitation practices can lead to an increased risk of these diseases in the upcoming season. A record of small fruit samples submitted to University of Kentucky Plant Disease Diagnostic Laboratories in 2018 are displayed here. The most common diseases of berries (blueberry, blackberry, raspberry, and strawberry) were root/crown rots (Phytophthora, Rhizoctonia, and Fusarium) and leaf spots (Figure 1). In grapes, the most common diseases were anthracnose and black rot (Figure 2).

Assessment of diseases likely to occur during the growing season provides the opportunity to utilize preventative management measures. The University of Kentucky Plant Pathology Department provides numerous publications with additional information and management options for these diseases. County Extension agents also provide information on disease diagnosis and management.
