Plenty of suggestions for healthy pecan orchards.

But it depends on your location (each pecan region
is different with respect to climate, soils, varieties),
size of trees, number of trees or acreage of the
orchard, equipment on hand, etc.  

You don't want to spray fungicides, so that leaves
biological sprays.  You need a sprayer that blasts
100-feet high and a selection of microbials and
biorationals if pecan scab is your problem.  You
also need to supply N fertility to promote thrifty
leaf and shoot growth.  Mycorrhizal inoculation
can help pecan tree health and fertility.

Feel free to write me off list if you want some
technical information on organic/sustainable
pecan production.   I've worked with pecan
growers for many years in Oklahoma, Texas,
Georgia, etc.

Anyone have suggestions for restoring the health of a fungus infested pecan orchard?

The trees are very old, the size of a good sized oak tree.  The are very productive, as far as numbers and size of pecans. But they are all destroyed by what I assume is Cladosporium caryigenum.

The ground beneath the trees is well covered with leaf mould, as we don't rake or hay in that area.

Any suggestions? Even if I were willing to spray fungicide (which I'm  not) and had time to do it (which I don't) I think the size of the trees would make it impossible without bringing in a cherry picker!
