Technical Abstract: Air potato, Dioscorea bulbifera, an herbaceous twining vine, native to tropical Asia, was introduced to Florida in 1905. Due to its ability to displace native species and disrupt natural processes such as fire and water flow, air potato has been listed as one of Florida’s most invasive plant species since 1993, and was placed on the Florida Noxious Weed List by the Florida Department of Agriculture and Consumer Services in 1999. In March 2016, air potato specimens displaying mosaic symptoms were collected in Alachua County, FL. Symptomatic leaf tissue tested positive for potyvirus infection using serological assays. Sequencing of RT-PCR amplicons confirmed the potyvirus diagnosis and suggested the virus infecting air potato is a new potyvirus species.
