Integrative Management of Bitter Pit in 'Honeycrisp' Apples
Dan Donahue, Tree Fruit Specialist
Eastern New York Commercial Horticulture
This article is a "meat and potatoes" summary of an American Society of Horticultural Science (ASHS) Postharvest Group webinar I presented on January 18, 2022. The webinar audience was a mix of research, extension, and commercial industry fruit workers from North America and Europe. As such, it was necessary to introduce the NYS apple industry, the Hudson Valley in particular, the Honeycrisp (HC) apple, and an overview of the 6-years of results from a Honeycrisp bitter pit (BP) research project for the most part conducted in the Hudson and Champlain valleys. Since our CCE-ENYCHP Produce Pages readers have seen much of this data presented at fruit schools and in previous articles, I'm going to focus on specific recommendations that you can implement for the 2022 growing season.
