In addition to its regular programme of activities, EPPO participates in various projects that are conducted over a fixed period of time and that may be funded by the Organization itself, a number of its members, or other organizations (e.g. EU).
- XF-ACTORS (2016-2020): EU-funded project about the European research on Xylella fastidiosa.
- EPPO Codes (2019- 2021): EU grant agreement for the enhancement of the EPPO Code System.
- Valitest (2018-2021): EU-funded project on validation data in plant health diagnostics.
- Quarantine Pests for Europe: EU funded project which allowed the preparation and publication of more than 300 datasheets on regulated pests.
- EPPO project on quarantine pests for forestry (2000-2005): this project provided an analysis of potential risks presented by forest pests present in the former USSR (particularly in its Asian part) for the EPPO region.
- TESTA (2012-2015): was a project financed by the 7th Framework Program of the European Union on Seed health: development of seed treatment methods, evidence for seed transmission and assessment of seed health.
- Q-detect: was a multi-disciplinary research network focused on developing innovative tools that enhance the capacity of phytosanitary inspectors to protect European agriculture and forestry sectors from invasive pests.
- Q-collect (2013-2015): was a project financed by the 7th Framework Program of the European Union. Its aim was to improve the status of reference collections important to plant health.
- EU project DROPSA (2014-2018): EU funded project during which alert lists of pests likely to be introduced in the EU with table grapes, apples, oranges and mandarins, and Vaccinium berries were prepared.
- EU project on RNQPs (2016-2018): EU funded project which aimed at developing a screening methodology and proposing a first list of Regulated Non-Quarantine Pests for the EU.
- LIFE-IAP (2016-2018): EU funded project which allowed the prioritization of invasive alien plants and the conduct of risk assessments on 16 selected species. This project also aimed at facilitating knowledge transfer and capacity building in pest risk analysis within the EU.
- EPPO Codes (2017-2018): the aim of this EU grant agreement was to enhance the EPPO Code System so that it better meets the new EU and global needs.
- Emphasis (2016-2019): EU funded project whose overall goal was to provide integrated response measures to predict, prevent and protect European agriculture, foresty and natural ecosystems against native and alien pests.
