Help with spots on Pcv. Golden Peacock 'Orange Beauty' suspicous spots on leaves and

[SJF]

Hello,
The orchid is in bloom. It has dark sunken areas and one of them is raised and bumpy. Only some parts of the plant are affected. At the bottom of one set of leaves and going down to the pseudobulb it is bumpy and serrated feeling. It is alos on a sheath of a flower stem. I sprayed it with neem oil. Can anyone help identify it? Thank you.

It could be many things but could be nothing. I would just watch it for now. Don't water overhead as that is a sure way to spread it. Water on leaves and flowers can spread many types of fungus and bacterial diseases. Just watch it for now and if it spreads I would cut out the affected areas and put cinnamon on the open cuts. Works for most of my problem orchids.

Thank you so much. I just repotted it two days ago. The leaves got more yellow on them. I broke off a tight bud repotting, but I wanted to see how the roots were and planted it in Orchiata

From looking at the photos in the first post I would suggest spraying with copper soap, it controls a lot of microbe pathogens and does not hurt my Cattleyas.

People say that copper compounds can damage Dendrobiums so I keep it away from the few Dendrobiums that I have, it is also toxic to Bromeliads.

I prefer the copper soap to copper sulfate such as Phyton in the belief that the copper soap may be less phytotoxic.

If things continue to spread, and since I can't identify which microbe type is causing a problem, I would just start rotating through every antimicrobial that I have - Heritage DF, thiomyl, chlorothalonil and mancozeb in addition to the copper soap.
