I have been hanging on every word (digest mode these days).   Rot here
usually starts at the base of leaves, at which stage there isn't enough
rotten mass to give off much of a stench.  From there it may or may not
progress to the rhizome, which can turn into a nasty puss pocket.  The stench
can be so horrendous, that I confess I usually don't inhale when I am
examining the damage.  In the cause of science, I will start sniffing my
rotten rhizomes (from a cautious distance!!!!!) to see if I can tell which
rot organism(s) are here.  My suspicion is that it's mostly bacterial soft
rot.

Unlike Rick, I am only interested in giving growing space to those tall
bearded irises that are the most disease resistent, I don't treat for
diseases and generally do not clean up dead foliage.  (I can hear the 'real'
gardeners and iris collectors groaning).  Rot either kills the plant or cures
itself, with no treatment.  Even in my rot prone garden and with my low key
approach to growing them, there are plenty of irises that do reasonably well.
 Figuring out which ones they are can be a challenge.

Does anybody know of any reports of biological control of southern blight?
 Seems like I remember reading that this organism can be much worse
(epidemic) if it gets started in sterilized beds where there are no critters
(nematodes?) left to eat it.

There are so many regional differences in how things grow (and rot), please
remember to ALWAYS sign your posts with where your garden is located.
