Hi I was gone most of yesterday. I want to thank everyone for responding to my problem.
Dave, your pictures look like my borers but mine were orange in color, I wish I had taken a photo but all I wanted to do was squash them into the concrete, so now I am not sure what I had or what I should do.
I dug all between the Iris in that bed looking for more but did not see any, I have about 18 Iris in that one bed and as of this morning they are all looking healthy but I am going to keep checking and if I find another I will take a photo.
I'm thinking maybe I should do what Tom said and use that Bayer Advance in that bed.
Marilyn, thanks for all that info you sent and also for the offer of a new rhizome, maybe I will take you up on that come spring.
I will keep you all updated on what is happening and once again thanks to all you guys for your help.
