A survey of viral diseases of Allium crops in New Zealand

Targeted surveillance was done in 2004/2005 and 2007 to determine the presence of viruses in ornamental and vegetable Allium crops in New Zealand. Several samples were tested for regulated viruses and viruses that commonly infect New Zealand’s Allium crops using enzyme-linked immunosorbent assay and...

Description
Summary:Targeted surveillance was done in 2004/2005 and 2007 to determine the presence of viruses in ornamental and vegetable Allium crops in New Zealand. Several samples were tested for regulated viruses and viruses that commonly infect New Zealand’s Allium crops using enzyme-linked immunosorbent assay and reverse transcription-polymerase chain reaction. Most viruses were found to occur in mixed infections in garlic, onion, shallot, and in the ornamentals collected from the North and South Islands. New host associations were observed for some viruses previously recorded in New Zealand. Three viruses, Garlic virus A , Iris yellow spot virus and Shallot virus × (syn. Shallot mite-borne latent virus), were detected for the first time in New Zealand. However, Impatiens necrotic spot virus , Shallot yellow stripe virus , Sint - Jan ’ s onion latent virus , Tobacco rattle virus and Tomato black ring virus were not detected in the Allium plants tested.
