Is there a natural wasy to treat scab on apple trees?

[miss_thenorth]

I just noticed what I believe to be scabs on the tiny fruit of my tree. It looks like it is going to be a good crop this year, and I don't want to lose it due to the scabs. Is there a natural way to treat this fungus?

Probably too late for this year but next year a dormant oil spray 2 weeks prior to bloom is supposed to help with this.
