treatment with trisodium phosphate and bleach solution are traditional methods for disinfection. The use of Streptomyces culture filtrate, which has also been shown to disinfect mad cow disease-causing prions, is another promising disinfectant. This method is shown to be effective in removing the virus from various tools, human nails, and orchid seeds. Another possible management strategy is development of plant resistance. An attempt to transform a mutant CymMV movement protein gene into Dendrobium orchids was slightly successful (9 of 259 plants were resistant and expressed the marker gene); the success of transformations actually conferring resistance appears to be related to a post-transcriptional gene silencing mechanism.
