Question by Mary-Frances B: Which organic product is best for spraying fruit trees?
We have 14 fruit trees and this year we have sprayed with organic spray. One pear tree (maybe 8 years old) has black leaves and we seem unable to stop the spread. Do we need to go to stronger?

we generally use dormant oil early in the spring than lime sulpher for fungal attacks. Sounds like you might have fire blight which is incurable. take a sample of the disease to your county extension agent to get it ID’ed properly and ask them what they would suggest (they will in all likelihood suggest non organic ways of dealing with the problem)
the book Rodale’s Garden Problem Solver has a pretty good section on spraying fruit trees organically
