Black Spot on Dwarf Meyers Lemon Tree

Question

I have a 12 year old dwarf meyer lemon plant with black spots on the leaves. I live in New England, so this time of year it is an outdoor plant. What is the best fungicide to use? I prefer organic gardening, so the least harmful to the plant, fruit, and nature.
