The common dormant spray for fungal pathogens is lime-sulfur.  It is 
commonly mixed with light oil to make a very effective dormant spray.  
Applied full strength at full dormancy and half strength at first bud, it 
will really help a tree keep clean.

Good orchard sanitation is always the first step in effective disease 
control.
