Bitter pit severity varies with cultivar and season, but Honeycrisp is particularly susceptible. Penn State has developed a new model for predicting bitter pit potential.

This is the second year of a grower-funded project to routinely assess fruit starch levels, ground color and other maturity indices to allow growers to make improved decisions about optimum harvest dates for long-term storage.

Late July and the beginning of August indicates the time to again intensify the careful management of internal fruit feeders such as codling moth (CM) and Oriental fruit moths (OFM) and leafrollers such as tufted apple bud moth (TABM) and to a lesser degree, obliquebanded leafroller (OBLR).

Pheromone traps are the best indicators for controlling CM and OFM. Detection of live BMSB nymphs in traps placed in orchards warrants an immediate insecticide application.

Given the mild winter and earliness of berry crops this year, it’s not a big surprise that spotted wing drosophila presence is early, too.

Fruit surface color is complex because it can be influenced by genetics and mutations, environmental factors, crop load, plant nutrition, plant stresses, and plant growth regulators.
