Краткое описание

The Phlox paniculata plants showing symptoms were discovered at a garden centre. They were vegetatively propagated from mother plants at a UK nursery, which are thought to have been obtained 4 years ago from another EU country. It seems unlikely that the virus would have remained latent within the mother plants at the propagator nursery without symptoms for such long period, so other sources of the virus are being considered. Plants showed some mottling and the lower epidermis was delaminated from the leaf. SpMV3 is a potyvirus and is presumed to be spread non-persistently by aphids. It is possible that aphids could spread this virus to other Phlox sp. as well as Spiranthes ceruna. All symptomatic plants have been destroyed and other lots at the same premises have been treated with insecticides to kill any possible aphid vectors. The plants will be held under statutory Notice to monitor for signs and symptoms of disease. Individual samples will be collected from both first and second generation mother plants being maintained by the propagating nursery and will be tested for the presence of the virus. Investigations will be carried out to trace any other Phlox sp. that may have been sent by the propagating nursery to other garden centres to ensure they are disease free.
