Test it (Agdia Kit) for CymMV and ORSV, if positive for either I destroy the plant. No cure for virus so unless you can completely isolate it away from all others (and impeccably clean tools) you risk spreading it.Phrag. Olaf Gruss flavum (pearcei x besseae flavum)
Repotted as per FirstRay's instructions on orchid S/H media, feeding and care. Not blaming any of these treatments...all other paphs and phrags repotted thus so far are thriving and blooming. Physan and other 'cides are my cautiously-used friends.
Insect damage was my first thought, but multiple traps and close inspections didn't reveal any culprits. I isolated this plant from all others two weeks ago and reinforced my virus-protection awareness and handling practices.
Haven'd seen visible evidence anywhere else. New to this magnificent obsession. If viral, what to do next?
