New Seed Extract (SE-PCR) tests for tomato and eggplant

Publicationdate: 12 januari 2024

We are introducing a new real-time RT-PCR to test the presence or absence of Pepino mosaic virus (PepMV) on seeds of tomato and eggplant. This test will replace the ELISA test as of January 1, 2024.

The (real-time) PCR is a technique for rapid amplification of RNA

This is done with the help of pathogen-specific building blocks. The increase in DNA can be monitored digitally at any time. This makes it possible to faster and with more certainty confirm whether the seed samples actually contain the pathogen.


Pepino mosaic virus (PepMV) is a Potexvirus that causes major problems in tomatoes and eggplants worldwide. Because the virus is very easily transmissible, the risk of spreading is high. Furthermore, transmissibility of this virus via seeds has been confirmed.

Other crops where the virus also causes problems include potatoes and tobacco.

PepMV on seed of tomato and eggplant

  • Sample size: 3,000 untreated seeds
  • Test fee: € 207
  • Duration test: 4 days

 For basic fees see price list 2024.

 Naktuinbouw Laboratories support sector

To support the sector, Naktuinbouw Laboratories continues to develop new tests that can support diagnosis on plants with symptoms or, on the other hand, check and guarantee freedom from certain viruses.
