The virus was detected and identified by using molecular methods: NGS and conventional PCR (NPPO of Spain, 2017-06). According to Ruiz-García et al. (2017), GSyV-1 has been recorded in the Americas (Brazil, Chile, USA), Africa (South Africa) and in the EPPO region (Czech Republic, France, Italy, Hungary, Slovakia, Turkey).

In Spain, an outbreak of Tomato spotted wilt virus (Tospovirus, TSWV – EPPO A2 List) was found for the first time in Castilla y Leon in May 2017. TSWV was detected in tomato (Solanum lycopersicum) plants in one nursery in the municipality of Valencia de Don Juan, province of León (NPPO of Spain, 2017-07).
The pest status of Tomato spotted wilt virus in Spain is officially declared as: Present, only in some parts of the Member State concerned.
In Romania, an outbreak of Tomato spotted wilt virus (Tospovirus, TSWV – EPPO A2 List) was found in June 2017. TSWV was detected in a tomato (Solanum lycopersicum) field (660 m²) located in the municipality of Oraşu Geoagiu (Hunedoara county). Phytosanitary measures were taken to eradicate the disease (NPPO of Romania, 2017-06).
The pest status of Tomato spotted wilt virus in Romania is officially declared as: Present, only in some parts of the Member State concerned, under eradication.
In Romania, an outbreak of Clavibacter michiganensis subsp. michiganensis (EPPO A2 List) was found in June 2017. The bacterium was detected in tomatoes (Solanum lycopersicum) grown in a glasshouse (800 m²) located in Bârcea Mare, Hunedoara county. It is suspected that the bacterium has been introduced into this glasshouse via infected tomato seeds whose origin could not be ascertained. Phytosanitary measures were taken to eradicate the disease.

In Estonia, an outbreak of Globodera rostochiensis (EPPO A2 List) was found in June 2017 during an official survey. Live cysts were identified in 5 soil samples which had been collected from a seed potato (Solanum tuberosum) production site (2 ha) in the village of Paunküla (Harju county). The identity of the nematode was confirmed by morphological and molecular (PCR) methods. On the infested site, it will be prohibited to grow seed potatoes and only the production of ware potatoes of resistant varieties will be allowed and all equipment used will have to be disinfected. These measures will be applied until 2023 (NPPO of Estonia, 2017).
The pest status of Globodera rostochiensis in Estonia is officially declared as: Present, under eradication.
In Finland, an outbreak of Globodera rostochiensis (EPPO A2 List) was reported in February 2017. The nematode was identified in soil samples from a potato (Solanum tuberosum) field (1 ha) located in the municipality of Säkylä (Satakunta region). Phytosanitary measures are being implemented to eradicate the pest (NPPO of Finland, 2017).

In Luxembourg, an outbreak of Globodera rostochiensis (EPPO A2 List) was reported in February 2017. The nematode was identified in soil samples from a potato (Solanum tuberosum) field (approximately 10 ha).

The pest status of Globodera rostochiensis in Luxembourg is officially declared as: Present, only in some parts of the Member State concerned.
In Germany, Thrips setosus (Thysanoptera: Thripidae – EPPO Alert List) was first found in 2015 on Hydrangea plants grown for cut flower production near Hamburg. In 2016, further findings were made in Baden-Württemberg. In 2017, an outbreak was reported on Hydrangea pot plants in a greenhouse of a nursery in North Rhine Westphalia. All infested plants and those belonging to the same lot were immediately destroyed. The production site concerned was then surveyed but no further infestation was found.
The pest status of Thrips setosus in Germany is officially declared as: Present, few occurrences, not confirmed by survey, only in some parts of the Member State concerned.
In Romania, an outbreak of Xanthomonas axonopodis pv. vesicatoria (EPPO A2 List) was found in June 2017. The bacterium was detected in tomatoes (Solanum lycopersicum) grown in a glasshouse (400 m²) located in Brănişca, Hunedoara county. Phytosanitary measures were taken to eradicate the disease.

- Absence
In March 2017, the NPPO of the Czech Republic had reported a suspected finding of Xylella fastidiosa (at that time EPPO A1 List but recently transferred to A2 List – see EPPO RS 2017/158) in a single plant of Polygala myrtifolia growing in a private house in the village of Husinec (EPPO RS 2017/084). This plant had been imported from Spain. Later, two plants of Phoenix canariensis imported from France were also suspected to be infected. However, confirmation tests were subsequently carried out by the laboratory in Bari (IT) and gave negative results.
