When Patty was here checking out my orchids today, we found a Catt with some odd lesions and yellowing leaves which I already cut off. Anybody got an idea about what this affliction might be?
So far the rest of the plant is looking pretty good, has fat pb's and a couple of new growths as well as a sheath that looks promising. I've treated everybody with dormant oil spray in January for bugs, and fungicide a month ago as well.
The lesions are raised, sort of feel 'warty' and dark brown but in most cases they don't go through to the 'up' side of the leaf. They're only on the backs.
