These applications are to protect the apples from spores being released from the cedar host in mid-spring. If cedar apple rust disease is diagnosed on apple fruits and leaves it is far too late to spray. Although curative fungicides also exist for cedar apple rust, they must still be applied before trees begin to develop symptoms. [13]
Apple trees are especially interesting as a research model in agriculture since it is known that apple production requires intensive spray schedules for control of pathogenic fungus V. inaequalis with as many as 15-22 sprays of fungicides per season in humid climate. [31] [32]
Adult insects emerge in late spring at the time apple trees are in flower, and are attracted towards the open flowers on warm sunny days.

Specifics of the spray intervals should also be determined by considering what spray is used, weather patterns (mainly rain and moisture), host species, host growth ...
Spray the leaves when you notice the larvae feeding (usually in June and July). Repeat the spray in two weeks, or if it rains. The most common disease of mountain ash is fire blight.
