Yes, many thanks, Tim.
I had not previously considered that Botrytis convoluta didn't have any smell, so this was valuable to me. Actually really hard to find good info about many iris diseases.
Mostly soft rot issues here, but I did receive a rhizome last summer, that subsequently showed suspicious symptoms of decay that I disposed of. It had a yeasty or alcohol smell and does not match the symptoms of Botrytis convoluta in other ways either, so I think I can rule that out now.
I bet most large scale iris growers needs to deal with Botrytis convoluta at one time or another, but I don't think all would be so open about it, so thanks again for sharing your experiences.
