Management
There is no way to cure a plant that has the virus. The only thing to do once a plant is infected is to destroy it. The best management solution is to prevent the spread of disease. This is accomplished through effective disinfection of tools used in cultivation, including any plastic containers and razor blades. Autoclaving, flaming, and chemical 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.

Famous quotes containing the word management:
“This we take it is the grand characteristic of our age. By our skill in Mechanism, it has come to pass, that in the management of external things we excel all other ages; while in whatever respects the pure moral nature, in true dignity of soul and character, we are perhaps inferior to most civilised ages.”
—Thomas Carlyle (1795–1881)
“People have described me as a “management bishop” but I say to my critics, “Jesus was a management expert too.””
—George Carey (b. 1935)
“The care of a house, the conduct of a home, the management of children, the instruction and government of servants, are as deserving of scientific treatment and scientific professors and lectureships as are the care of farms, the management of manure and crops, and the raising and care of stock.”
—Catherine E. Beecher (1800–1878)
