Abstract:
Clover yellow vein virus (ClYVV), Bidens mottle virus (BiMoV) and Apium virus Y (ApVY) were identified in Ammi majus in south Florida cut flower production areas in 2005 and/or 2007. To the best of our knowledge, these results are the first report of ClYVV and BiMoV infection of A. majus in North America and the first report of ApVY in North America. Common weeds in Florida are known reservoir hosts for ClYVV including white clover (Trifolium repens) and for BiMoV including Spanish needles (Bidens pilosa) and tropical soda apple (Solanum viarum). Detection of ClYVV and BiMoV in other ornamental crops in Florida suggests that these viruses pose a broader risk to ornamental production.
