Irises: Iris problem, 1 by astead2

Can anyone please help identify the possible culprit affecting this iris? We've looked in a Ortho book and believe, from that reference, that it might be some type of a fungus, however, only specific plants are affected with others not affected at all. The rhisomes are big and healthy. We've spotted some type of beetle on a nearby rose, but haven't located any on this iris. If the fungus is, indeed, the problem, must we really dig up the plants and burn them? Will some type of fungicide help or, perhaps, cutting the foliage off and seeing if that makes any kind of difference? Somebody - please help me!

SIncere thanks,
