Plum pox virus [Potyviridae: Virus] PPV Yes (Navratil et al. 2005) No records found Yes. Infects P. persica (Adams 1995). PPV can be isolated from fruit and seed. There have been reports of aphids being able to transmit the virus from infected fruit (Gildow et al. 2004). Important method of spread is via diseased plant material (Adams 1995). Yes. Considerable spread can occur from new disease foci before infections are recognised (Adams 1995). Plum pox virus is extremely difficult to eradicate once established. Affects all Prunus spp. in a variety of environments similar to Australia. The virus is transmitted by grafting. It is also transmitted by two main aphid vectors Aphis spiraecola and Myzus persicae. Other aphids able to transmit the virus are: Aphis craccivora, A. fabae, Brachycaudus cardui, B. helychrysi, B. persicae, Hyalopterus pruni, Myzus varians, Phorodon humuli (CABI & EPPO 2007; Gildow et al. 2004), A. gossypii, Rhopalosiphum padi and A. hederae (Labonne et al. 1995). Yes. Plum pox arrival in Australia would see the loss of overseas and potentially new markets. PPV reduces the value and marketability of many apricot and some other Prunus spp. cultivars that have been naturally infected. Some are latently infected and act as a reservoir for continued infection cycles. There is a high cost in living with PPV through testing, eradication, and breeding resistant cultivars such as in Europe and USA. Yes (EP)
