Jane, Your problem sounds a lot like the same problem I have with Phals. I was on here a few years ago looking for answers. I made a web site about my problem, which I have not updated in years: http://www.geocities.com/tlswilso/Phal_problems_2-15-04.html Since I last updated the site, every infected Phal has died. The last one to die, the first orchid I ever owned, died around Thanksgiving (Late November) 2006. After all the ones with the disease were gone, I had a person give a nice big healthy Phal to me. I grew it in the same location where the others died and it now has the same disease. I also purchased a seedling Phal which I grew in a completely different location (a different building). It started showing the disease in about 4 or 5 months. The only thing the 2 locations have in common is that I move other orchids back and forth between the two places. I have come to believe that the disease only kills Phals but is carried by other orchids that either show no signs of disease or show signs that I don't recognize as the same disease.
