  • Nemesia ring necrosis virus (NeRNV) is a member of the Tymovirus genus. This virus has a relatively narrow confirmed host range, infecting ornamental varieties of Alonsoa, Diascia, Lobelia, Nemesia, Sutera and Verbena. Symptomology varies by host and ranges from mild foliar mosaic and chlorotic flecks to severe leaf necrosis, rendering plants unmarketable.
