ToBRFV found in Poland, three new outbreaks reported in the UK

The NPPO of Poland recently informed the EPPO Secretariat of the first detection of tomato brown rugose fruit virus (Tobamovirus, ToBRFV – EPPO Alert List) on its territory. A sample of tomato (Solanum lycopersicum) grown in a greenhouse (1 ha) in the municipality of Barczewo (province of Warmińsko-Mazurskie) was sent by the grower to a Dutch private laboratory at the end of March 2020. The identity of the pathogen was confirmed at the end of April. 

The pest status of Tomato brown rugose fruit virus in Poland is officially declared as: Present.

United Kingdom
In the United Kingdom, tomato brown rugose fruit virus (Tobamovirus, ToBRFV – EPPO Alert List) was first detected in July 2019 in a tomato greenhouse in Kent (South East England) (EPPO RS 2019/163) and later in Worcestershire (West Midlands, England) (EPPO RS 2020/078). The NPPO of the United Kingdom recently informed the EPPO Secretariat of the eradication of the outbreak in Kent. Eradication measures included the removal of all plants from the affected glasshouse and its disinfection, followed by a 14-week period of the glasshouse being kept clear of plants.

Three new outbreaks have been reported recently as part of the official surveillance programme:

  • in West Midlands (England), the presence of ToBRFV was confirmed in two greenhouses producing tomato (Solanum lycopersicum) fruit on 2020-03-31 and 2020-05-15 respectively. 
  • in the East of England, the presence of ToBRFV was confirmed in one greenhouse producing tomato fruit on 2020-03-31.

For these three cases, containment measures are being applied to prevent further spread of the virus during fruit production. Once fruit had been harvested, eradication measures will be applied (destruction of plants, disinfection of the glasshouse).

The pest status of Tomato brown rugose fruit virus in the United Kingdom is officially declared as: Transient, actionable, under eradication.

ToBRFV in the USA
In the USA, tomato brown rugose fruit virus (Tobamovirus, ToBRFV – EPPO Alert List) was first detected in September 2018 in a tomato greenhouse in California (EPPO RS 2019/027) and declared eradicated. USDA-APHIS recently announced that they will conduct a survey in glasshouses producing tomatoes after the confirmation of several isolated detections of ToBRFV in commercial greenhouses during the winter 2019-2020. The location of these findings was not given. It may be noted that seed of Solanum pimpinellifolium from the USA have been recently intercepted in the United-Kingdom as they tested positive for ToBRFV (EPPO RS 2020/114). S. pimpinellifolium had not been recorded as a host plant so far.

Import requirements of tomato and pepper fruit to the USA were extended to fruit from the Dominican Republic after detection of ToBRFV in imported fruit. The EPPO Secretariat had no previous indication of the presence of ToBRFV in Dominican Republic.

The situation of Tomato brown rugose fruit virus in the USA can be described as: Present, few occurrences.

Tomato brown rugose fruit virus does not occur in Egypt
In the EPPO RS 2020/102, it was reported that tomato brown rugose fruit virus (Tobamovirus, ToBRFV – EPPO Alert List) had been detected for the first time in tomato samples from Egypt during a research study. After further investigations, the NPPO of Egypt considered that the results of this research study were not reliable and therefore could not be used to indicate the presence of the virus in Egypt.

The situation of Tomato brown rugose fruit virus in Egypt can be described as: Absent.
