Detection of Tomato spotted wilt virus in Pays-de-la-Loire region (FR)
The NPPO of France recently informed the EPPO Secretariat of the detection of Tomato spotted wilt virus (Tospovirus, TSWV - EPPO A2 List) in Pays-de-la-Loire region. In July 2013, TSWV was found in a glasshouse of potted chrysanthemums where mild leaf symptoms were observed. The virus was detected in a sample composed of a dozen leaves collected from 6 plants (each potted chrysanthemum had been produced from 4 cuttings). No thrips vectors were found in the glasshouse. Tracing-back studies are underway on the premises of the grower which had produced the cuttings (located in another region), and at present no TSWV infection has been detected in the mother plants. All chrysanthemum plants which tested positive and all symptomatic plants have been destroyed.
The pest status of Tomato spotted wilt virus in France is officially declared as: Present, restricted distribution.
