Pepino mosaic virus (PepMV) is highly contagious and has a significant potential to cause damage in protected tomato production. PepMV was first reported in 1980 from pepino plants (Solanum muricatum) collected in Peru in 1974. In Europe it was first observed in 1999 in the United Kingdom and the Netherlands. During the last decade it has spread quickly and has now established itself both inside and outside Europe. Over the last few years new strains and genetic recombinants have appeared.
EPPO, the intergovernmental organization responsible for European cooperation in plant health, will publish the Pepeira protocols that can be used with confidence by National Plant Protection Organisations within the EU and laboratories in other countries that trade with the EU.
An important deliverable of the project will be a Pest Risk Analysis (PRA) of the virus. This PRA will provide the regulatory bodies within the EU and its Member States with the framework needed to design and implement the necessary phytosanitary measures.
- Distinct mottle and mosaic
- Spiky, nettle-like head
- Bubbling of the leaf surface & distortion
- Sometimes a severe yellow mosaic or even necrosis may develop
- Often only small, angular yellow spots are seen
- Fruit symptoms range from mild mottle & marbling to severe uneven ripening
- Readily mechanically transmitted:
- Via contaminated tools
- On hands or clothing
- Direct plant-to-plant contact
- Propagation material
- Grafting or taking cuttings
Control of PepMV
- Via good end-of-crop hygiene programme - clean up and disinfect
- At outbreak sites, PepMV is widespread: on most surfaces, debris and volunteer tomatoes
- Virus can survive for several weeks under suitable conditions
