Paph concolor and praestans

Recently, many of my paphs are infected with the crown rot bacteria.  Many healthy plants started turning soft and mushy and died.  The base of the older leaves would first show a patch of soft brown which then spread to the upper portion of the leaf and other leaves as well.

After many sessions of dunking and spraying with Physan, some of the plants survived and are begining to flower again.  Paph concolor is one of them.  The flower size and shape is not as good as before but hopefully this will improve.

This Paph praestans did not get attaked by the bacteria but another plant was.  This plant flowers annually without fail.
