Update on the situation of Tomato torrado virus in Hungary
Tomato torrado virus (ToTV – EPPO Alert List) was first found in Hungary in a commercial tomato glasshouse in October 2007 (EPPO RS 2008/129). Two other outbreaks were also reported by Alfaro-Fernández et al. (2009) in glasshouses producing tomato fruits. During surveys carried out in 2009, 29 samples were collected on young plants from 8 counties and all results were negative. 51 samples were also collected from tomato crops (intended for fruit production) and 1 sample tested positive by RT-PCR. The source of this infection, and that of the previous 3 cases, remains unknown. It was generally observed that the ToTV infections were detected in production sites which were heavily infested by Trialeurodes vaporariorum. The 4 outbreaks occurred at different sites in Hungary and no relation could be found between them. In all cases, measures were taken to eliminate the virus.
The pest status of Tomato torrado virus in Hungary is officially declared as: Present, with a few occurrences. Survey will continue in 2010 in the tomato-growing areas of the country.
