2020 Spring

Second round of test performance studies (TPS) – start date

The second round of TPS will start in spring 2020. If you are interested in participating to one or several TPS, please send us an email to by mid-October 2019 at the latest.

IMPORTANT: If you are not a VALITEST project partner and as the project’s budget does not allow any external funding, the participation to the TPS will be at your own cost. As a participant to the TPS, you would receive the evaluation report and you would be associated to the results exploitation.

Review meeting in Brussel

  • 28 January 2020

The VALITEST steering committee presented the achievements of the project at a review meeting in Brussels on the 28th of January. The project officer and the two reviewers were satisfied with the progress made. The deliverables of the first period will soon be made available via this website.

Work continues: the second TPS on 6 different pests is already launched to be performed in spring 2020. Guidelines on HTS are in preparation and will be sent for review to an international group of HTS experts who have volunteered to help the project. The preparation of EPPO guidelines on reference material has been initiated. More work on statistical analyses of TPS results (analysis of TPS 1 results) is under preparation.

A discussion with risk managers on how tests are chosen and how validation data come in the picture, is planned for the next EPPO Panel on Phytosanitary Measures.

Second round of test performance studies (TPS) – Pests selection

The preparation of the second round of Test performance studies (TPS) has started. Six pests (3 virus, 2 bacteria, 1 fungi) have been selected thanks to the collaborative work of the people from WP1 and WP4. The organizers (ANSES, CREA, FERA, NIB, UNITO) of each TPS has been identified. The selection of the tests that will be part of each TPS is ongoing.

First round of test performance studies (TPS) – follow up

The first round of Test Performance Studies (TPS) has been launched in 2019. For each TPS, samples have been sent to 17 to 32 participants from different countries. In total, 5083 samples have been prepared and circulated to participants by May 2019. Bench work has been performed by the different participants and analysis of the results is ongoing. Results of TPS studies are expected by the beginning of next year.

First round test performance studies (TPS)

The organisation of the first round test performance studies (TPS) has been started. Mid-January potential partners have been invited for the different test performance studies. The selection of the participants based on pre-defined criteria will be finished soon. Each TPS includes several methods and in some cases several tests per method. Preliminary studies for the selection of these tests will be finished at the end of February.
The following methods are included in the TPS organized in this first round. A second round on other pests will be organised in 2020.

  • Erwinia amylovora: real-time PCR, LAMP, LFD
  • Pantoea stewartii: PCR, real-time PCR, LAMP
  • citrus tristeza virus: RT-PCR, real-time PCR, LAMP, ELISA, Immunoprinting, LFD
  • plum pox virus: RT-PCR, real-time RT-PCR, ELISA
  • Fusarium circinatum: Plating, PCR, real-time PCR
  • Bursaphelenchus xylophilus: PCR, real-time PCR, LAMP
