Background
Plum pox is a virus disease of stone fruit species (peaches, plums, etc.) that first appeared in Pennsylvania October of 1999. The plum pox virus can be carried in live nursery stock, in grafts and budwood of infected plants, and is transmitted from one plant to another by the feeding of several species of aphid. Plum pox virus does not kill infected trees, but it causes yield losses to growers and reduces the marketability of fruit.
Subsequent to its discovery in the United States, an infestation of plum pox virus was detected in Ontario and Nova Scotia, Canada. It appears that this infestation pre-dates the one in Pennsylvania. At this time there is not evidence that the two infestations are related. The strain detected in the US and Canada is the D strain from Europe which is not the most virulent of plum pox strains, and which does not appear to infect cherry species.
