Can I spray my fruit trees with Bonide Liquid Copper Fungicide Concentrate?

I have a mixed orchard of pears/peaches/cherries and apples. Some buds are silver tip, some are swelling, some are half inch green, and some are tight clusters.


The Bonide Liquid Copper Fungicide Product Label States- Apples & Pears: Do  not exceed one application during the fall, late dormant period. Do not exceed one application between silver tip and green tip growth stages. May cause russeting of susceptible apple varieties. Repeat application every 7-10 days during bloom and growing season if needed. 
For Cherry, Peach,etc: For bacterial canker, apply as a dormant spray as buds begin to swell, repeating at the bud burst stage, and weekly thereafter as needed, up to six sprays. In the fall spray again at 10 and 80% leaf fall. For brown rot, blossom blight, apply full cover spray at delayed dormant (but swell), popcorn, full bloom, and petal fall stages. Repeat application every 7-10 days if needed.
