I believe Janis Rucksans book "Burried Treasure" gives some information on
this subject, with advice for the crop rotation, and treatment regarding
various fungal and other problems. There was also a thread on the scottish
rock garden club forum last year discussing a black mould on the anthers of
muscari and scilla in which Janis gave significant information and pictures.
I have been advised by another nurseryman that control of "ink spot" on
reticulata Iris is only really achieved by replanting in fresh ground every
year, (though I do feel from observation of reticulata Iris, that Ink spot
primarily is brought about by irregular temperatures and periods of drought
during spring growth )
