Walter, around here leaf spot is ubiquitous. Some varieties show more
resistance than others, but darn near every fan on bearded irises sports
some spot. If it's linked to a gene, I think the gene must be essential
for an iris to be an iris!
I do not spray. I DO practice "clean cultivation" and trimming--sometimes
to extremes (time permitting). However, anyone wanting to study the
problem will find ample material in my iris beds, no matter what I have
done, or what the weather has been. Some weather conditions --humidity,
lots of rain, do seem to make it worse.
That's the view from my garden, anyway.
