Hello all,

My radiata is blooming and smells nice. Unfortunately it has lately developed some unsightly leaf spots. This happened after it either was rained on several times or came into contact with some kind of wastewater.

I think it is time to break out the copper. I did virus test it and got what I believe is a definitive negative (didn’t see any lines. That said, my eyes aren’t great).

I believe this is a bacteria. It seems to be not under control. Would copper be the best measure to take?

I just noticed this thread. What happened? Any chance those leaves are on the oldest pseudobulbs, and just dropping naturally?

It is happening on most of the leaves, even the new ones.

It seems more aesthetic than anything else.

I would take a piece to your county agriculture department, or a university with a botany or ag department. They can look at it under a microscope.
