Advice needed to determine possible virus

[mshurst]

Hi everyone: I am new. First time posting, and first time finding the orchid board. One of your existing members and a member of our local orchid club told me that if anyone could answer my question, it would be the members of this board. I have been growing orchids for about 25 years.

In repotting one of my orchids ( Lc Princess Margaret, which has a 6 inch lavender bloom), I discovered when I cut the plant apart there is a distinct red ring in the psuedobulb. Somewhere in the back of my mind, I have heard that this is a very serious virus. This is a very healthy looking plant, and one that I have had for years.

I have looked in my orchid diseases book, and checked the web, but have not found any information.

Does anyone know? I would appreciate any and all replies. Thanks
