Interpretive Summary: Polianthes tuberosa, commonly known as tuberose, is a bulbous ornamental plant native to Mexico that is grown as an ornamental crop. In September 2016, tuberose plants with mosaic symptoms were observed in a Miami-Dade County, Florida nursery. Diagnostic testing demonstrated infection with a potyvirus. Further testing identified the potyvirus as Tuberose mild mottle virus. In this report, we document the detection of this virus in Florida to share this important information with growers, Extension personnel, crop consultants, and regulatory and research scientists in Florida and the Caribbean.

Technical Abstract: Tuberose mild mottle virus is a potyvirus originally described from Polianthes tuberosa in Asia. This plant, commonly known as tuberose, was observed with mosaic symptoms in an ornamental nursery in Miami-Dade County Florida in September 2016. Testing of these symptomatic plants by multiple diagnostic methods demonstrated the presence of Tuberose mild mottle virus in Florida.
