Shrunken bulbs with black spots on cymbidiums

[drmab]

I recently received 4 large cymbidiums from SF , I don’t know how they were raised, (maybe outdoors?) but it took 4 days for shipping them bare root.
On arrival, these were mature plants, with shrunken bulbs and black spots on both the bulbs and leaves. (I don’t think these were related to the 4 day shipping!)
Is this a virus, or simply under watering?
I have now repotted them in bark, and spray them with listerine and a spray of sulfur and pyrethrins ( Bonide citrus fertilizer product), and have not watered them since repotting 4 days ago.
I would appreciate any ideas/advice. Thank you.
