This quickscan of tomato necrotic spot virus (ToNSV) was prompted by the interception of the virus on Phaseolus beans for consumption imported from Morocco.

ToNSV is not known to be present in the EU. It has been reported from the United States but may have a wider distribution considering the interception on produce from Morocco.

Tomato (Solanum lycopersicum L.) is known as a host plant. The interception indicates that common bean (Phaseolus vulgaris) is also a host. The host plant status of pepper (Capsicum sp.) and onion (Allium cepa) needs confirmation.

ToNSV may be able to establish in the EU in greenhouses and the open field where host plants are present.

If ToNSV were to become established economic impacts can be expected.

Key uncertainty for both the likelihood of establishment and the magnitude of the potential impact is the mode of transmission and how fast ToNSV can spread in a crop. The thrips species Frankliniella occidentalis may be able to transmit the virus but this needs confirmation.
