    Oop! Sorry Bobby for some reason I didn’t see your post when I logged on. It showed an unanswered post. I think whenever I share several links in the same post, it takes longer for the answered post to show. Laura

    I’m not sure and wondering if this might be leaf spot disease (Mycosphaerella macrospora formely Didymellina macrospora)? Check out the included link below for more information and treatment. Best you contact the local Agricultural Extension Service for a confirmed diagnosis. Best wishes! http://www.ksuhortnewsletter.org/newsletters/iris-leaf-spot-control-starts-now

    That would be so disheartening! The pictures IÕve seen of borer symptoms look a lot like your pictures. From what I have read you could divide and transplant your irises now. Inspect the rhizomes before replanting. From Missouri botanical gardens: When replanting your iris beds, it is important to trim away damaged or rotted areas on the rhizomes. To eliminate soft rots caused by bacteria, cut off the damaged parts of the rhizomes and dip the undamaged portions in a solution of 1Ðpart household chlorine bleach and 9 parts of water. See WalterÕs notes on iris borers: http://www.walterreeves.com/landscaping/iris-dealing-with-borers/ Also Missouri botanical gardens: https://www.missouribotanicalgarden.org/gardens-gardening/your-garden/help-for-the-home-gardener/advice-tips-resources/pests-and-problems/insects/caterpillars/iris-borer.aspx
