Black spot on my zoo leaves
 

Anyone can help?
I got this zootrophion dayanum from an orchid auction a month ago. It was healthy then. It is still in the original pot. It is now covered with black spots, each about 1-2 mm in diameter. Is this as case of fungus? and how can I get rid of these spots?

Thanks,
pax

Sorry, Found lots of information after I posted. One possibility is bug bites..? I will see if some of the solutions provided in the sticky threads could help and will post any progress (hopefully)

Most likely bacterial brown spot lesions. A good bacteriacide/fungicide would work if used quickly. It comes with warm weather and moisture. Overhead watering helps spread it. Go to stauorchidsociety.org and look at Pseudomonas infections. Click on "more pictures of brown or soft rot on cattleyas".
