[NAFEX] Powdery Mildew in the mulch pile

Regarding the issue of putting powdery mildew in the mulch pile, powdery 
mildew is an obligate parasite or biotroph and must have living tissue to 
continue growing.  However, some of the spores (cleistothecia) could 
probably survive the composting if not properly done.
