Doesn't seem to have spread. Is this something I can cure or do I need to destroy the plant? Again, I've been using cleary's on it, which is a fungicide, systemic.
I thought black rot was a bacterial issue. So maybe fungicide will not do. Perhaps you can try Physan 20 instead? It's really hard to get rid od. In all honesty, if this was my plant I'd toss it. Sorry to hear of your orchid problems recently.
