PPV is the cause of a serious plant disease, affecting a number of species, including peach, nectarine, apricot and plum. Several aphid species can serve as carriers of the virus. The virus stays viable in the aphid’s mouthparts for a period of approximately one hour and most aphids can generally transmit infection several hundred meters from the initial source plant.
