Bitter Rot and Sooty Blotch/Flyspeck Management
Mike Basedow, Tree Fruit Specialist
Eastern New York Commercial Horticulture
Late June through harvest is the critical time for bitter rot management. Warm temperatures and rainfall are the ideal conditions for disease development. Growers are encouraged to apply fungicides on bitter rot susceptible apple blocks before any rain event starting in late June. Management programs for bitter rot will also manage SBFS. Specific fungicide recommendations are described for the summer.
