Dormancy in most trees in induced by light duration and sometimes by temp.
If your leaf problem is uniform over the entire plant it might just be
induced dormancy.
If the problem starts in one area of the plant and then spreads its most
likely a pathogen.
A good number of trees lose there leave in late summer here in the North do
to pathogens instead of dormancy -- its part of the normal process. Native
plants seem to suffer more pathogen problems than non native plants.
Maybe their is a university there with a good hort program that can do a
culture of the leaves to see if its a pathogen.
