    Default Luella purpurata- Dark spots on leaves

    Dear All
    I did not find a section for diseases in orchids so I am using this forum.

    I have a young Laelia that developed some black spotting, small in the beginning but now it is spreading through the leave.

    The first time this happened I cut the affected part and used cinnamon on it to seal the wound. Now and because she does not have many leaves, I used Physan20 and disinfected roots and leaves, and used cinnamon on the spots (see picture).
    Is this pseudomonas Cattleya?
    I am keeping the plant in sun and relative dry media (lots of ventilation as well).

    Let me know if I am wrong and there is anything else I can do.

    Ana looks to me like Cecospora if possible better cut the infected side as you mention it's increasing in size, keep it the plant dry and always spray the water early in the morning and the raw area cover with cinnamon as usual.

    You don't worry the new pseudobulb looks so promising and will compensate the lost without you realize it later.
