TSP is the best defense to control the spread of orchid virus.

	These photos are all from  Phal. Paifangs Queen'Brother', it tested positive for CYMV. It is difficult to tell if a plant is infected just by looking, many eronious symptoms. I had a stem from this in flask for over a year and this ring spotting appeared in the flask. This had to be caused by the CYMV.

Host of Tomato Spotted Wilt Virus And Impatiens Necrotic Spot Virus I placed this here to give an example of how many different species a virus will infect. I believe that if CyMV or any other of the orchid virus were tested on a similar number of potential host plants that we would see many more possible indicator plants.
