Present situation of five tomato and cucurbit viruses in France
The present situation in France of five tomato and cucurbit viruses, now subjected to an official decree of compulsory control, is given below.
Cucurbit yellow stunting disorder crinivirus (CYSDV - EPPO Alert List): during winter 2001/2002, two outbreaks were detected in Languedoc-Roussillon on cucurbits grown under glasshouses, and successfully eradicated.
Tomato chlorosis crinivirus (ToCV – EPPO Alert List): in 2002, ToCV was detected for the first time in the south of France in Languedoc-Roussillon and Provence-Alpes-Côte-d’Azur. Phytosanitary measures were taken to eradicate these isolated outbreaks, according to the official decree of compulsory control.
Tomato yellow leaf curl begomovirus (TYLCV – EPPO A2 quarantine pest): in 1999 an outbreak of TYLCV was found in the South of France and successfully eradicated (see EPPO RS 2000/094 & 2000/168). On the 9th of July 2002 another outbreak was observed in Bouches-du-Rhône, at some distance from the earlier one. The virus was found on tomatoes grown under plastic tunnels at Eygalières (canton of Orgon, east of St Rémi de Provence). Tomato seedlings had recently been imported from Spain. Eradication measures have immediately been taken: destruction of tomatoes and plastic tunnels, strict surveillance of the canton where the virus was discovered and surrounding ones. No other outbreak was found in this region, but monitoring will continue.
During surveys, Tomato infectious chlorosis crinivirus and Cucumber vein yellowing ipomovirus (both on the EPPO Alert List) were not detected in France.
The situation of the following viruses in France and be described as follows:
Cucumber vein yellowing ipomovirus: Absent, confirmed by survey.
Cucurbit yellow stunting disorder crinivirus: Absent, eradicated.
Tomato chlorosis crinivirus: Present, 2 outbreaks found in Languedoc-Roussillon and Provence-Alpes-Côte-d’Azur, under eradication.
Tomato infectious chlorosis crinivirus: Absent, confirmed by survey.
Tomato yellow leaf curl begomovirus: Present, 1 outbreak found at Eygalières (Bouches-du-Rhône), under eradication.
