(dormant) spray program for sweet cherry?

Hi All,
we live in east coast, a high humidity environment. In the past spring and summer, sweet cherry has powdery mildew and minor aphids problem.

As going into the first winter, I can "imagine" the enemies are bacterial canker and brown rot. I am trying to develop a least toxic home spray schedule that adapts to our weather condition.

Sweet cherry :
Oct: copper soap (copper octanoate)
Nov: copper soap
Dormant: (after leaves fall) Superior dormant oils + copper soap (mix)
Delayed-Dormant: Superior dormant oils + Bacillus subtilis (mix)
Prebloom: Neem oil extract
Petal Fall & Shuck: Wettable sulfur

- If aphids, Insecticidal soap
- If powdery mildew, potassium bicarbonate
- If rain within 4 weeks of harvest, calcium chloride (?) or high tunnel (i wish)

Does above program make sense? Am I missing something? Am I too aggressive? Any suggestion / comment are welcome.

Thank you

Alex
