First report of Iris yellow spot tospovirus in France
The French NPPO recently informed the EPPO Secretariat of the first record of Iris yellow spot tospovirus (IYSV - EPPO Alert List) on its territory. The virus was detected by DAS-ELISA on 3 samples of leek (Allium porrum), all originating from the ‘Pays de la Loire’ region. The origin of the infection remained unknown. As the vector of IYSV, Thrips tabaci, is present in France and as disease symptoms are not very characteristic of the virus, a survey has been initiated to delimit the extent of the infection.
The situation of Iris yellow spot tospovirus in France can be described as follows: Present, first detected in August 2006 on 3 samples of Allium porrum, in ‘Pays de la Loire’ region, surveys are ongoing.
