Outbreak of Tomato brown rugose fruit virus (Tobamovirus – ToBRFV) impact on seed business
A new seed-borne viral disease of tomatoes first observed in Israel in 2014 has since been detected in Europe, the Middle-East, and North America. WTO reported that several countries has restricted the seed imported to the country via plant quarantine in 2019 . No tomato varieties are known to be resistant to the Tomato brown rugose fruit virus. Preventing the spread of the virus is currently the best means of managing the disease. ISHI-Veg had released the latest publication of “Detection of Infectious Tomato brown rugose fruit virus (ToBRFV) in Tomato and Pepper Seed”, May 2019. EPPO decided to add it to the EPPO Alert List 2019 because outbreaks have recently occurred in Italy (EPPO RS 2019/013), in Mexico (EPPO RS 2019/014) and China (EPPO RS 2019/143) where the virus causes major concerns for growers of tomato and capsicum. No commercial tomato varieties has been found to be resistant to ToBRV. The major resistance genes in tomato that provide resistance to other tobamoviruses do not provide resistance to ToBRFV. It is advise to strict sanitary practices because the virus is easily spread by mechanical transmission like other obamoviruses. It therefore seems desirable to avoid its further introduction and spread within the region.
