Narcissus late season yellows virus - (NLSYV0)
Daffodil: Narcissus sp
Present: only in some areas
Perth, Western Australia in one home garden. It is possible the virus is present in other states, but has not been tested for.
A virus with filamentous particles about 750 nm long and 12 nm in diameter. The virus is transmissible by the aphid Myzus persicae and induces, in plant host cells, pinwheel inclusion bodies typical of potyviruses. Narcissus is the only known host, but not all cultivars are susceptible to infection. Symptoms are mild mottle, some leaf distortion and mild stunting.
First record of this virus in Australia, however it is likely to be present across metropolitan Perth due to the movement of bulbs. The Western Australian Department of Agriculture and Food is not undertaking any active management in response to this detection. It is likely to be of limited economic importance to the ornamentals industry.
