Call - 2020

Information on research topics proposed for transnational collaboration through Euphresco will be displayed on this page.

The members of the Euphresco network propose each year a number of ideas that could lead to collaborations provided that they raise transnational interest, that coordinators are identified and national funds are committed.

Collaboration with non-Euphresco organisations (research institutes, universities, private companies and other plant health stakeholders) is encouraged and administrative formalities are very light. For any question, please contact the Euphresco coordinator.

The table below summarizes the research topics proposed for transnational collaboration in 2020.

Plant health status of Fagus spp.

Short description: the project should gather knowledge on the risk of introduction/establishment of beech leaf disease in Europe. The project should: i) define the current phytosanitary status of Fagus spp. in Europe; ii) screen imported dormant beech to confirm routes of entry for Litylenchus spp.; iii) perform high-throughput sequencing studies of the beech leaf microbiome to identify differences between European and American trees, which may modify impacts iv) facilitate exchange of information through visits to infested beech forests in the US to improve understanding of management practices.

Expected output: knowledge on the plant health status of Fagus spp.; deeper understanding of the biology and epidemiology of Litylenchus spp.; knowledge on management practices.

The organizations to involve and activities to be covered in this collaboration will be agreed upon in Spring 2020.

The organizations to involve and activities to be covered in this collaboration will be agreed upon in Spring 2020.

Use of basic substances as socially acceptable phytosanitary treatments both for consignments and at the place of production

Short description: basic substances are approved for use in the EU and are products which are already sold for other purposes, e.g. as a foodstuff or a cosmetic, but which can also serve as a plant protection product. The project should test and validate the use of basic substances as phytosanitary treatments to get desired results.

Expected output: validation of basic substances as plant protection products.

The organizations to involve and activities to be covered in this collaboration will be agreed upon in Spring 2020.

Plant Protection Products (PPP) resistance

Short description: coordination between countries for resistance analyses and the development of validated standardized resistance test methods is greatly needed. This could come to life as a network of national laboratories carrying out resistance analyses (see the initiative https://www.r4p-inra.fr/en/home-2/). The project should bring experts (authorities responsible for registration of PPP, agrochemical companies etc.) together to share methodologies and knowledge on cases of resistance on PPP.

Expected output: a network to facilitate the sharing of knowledge on PPP resistance.

The organizations to involve and activities to be covered in this collaboration will be agreed upon in Spring 2020.

ToBRFV: Host plants and factors allowing infection in pepper

Short description: the aim of the project is to investigate the host range of Tomato brown rugose fruit virus (ToBRFV) under natural conditions for aubergine, weed species, ornamentals, etc. Also, information concerning the host status of Capsicum spp. harbouring the L-resistance gene could be collected worldwide to investigate whether ToBRFV has already overcome the L-resistance gene, and in that case whether co-infections with other viruses may play a role in bypassing the L-resistance.

Expected output: knowledge on biology and epidemiology.

The organizations to involve and activities to be covered in this collaboration will be agreed upon in Spring 2020.

Mosses and lichens

Short description: living mosses and lichens are increasingly used for decorations (with bouquets, to cover clay pots, kokedamas etc.), in gardens (Japanese, modern, garden mosses etc.), as green roofs, on walls etc. Mosses and lichens are not regulated at import in several EPPO Countries (e.g. in the European Union) and could host several pests (e.g. Lambdina fiscellaria) when collected in the forest and imported fresh into the EPPO region. Collection of trade as well as surveillance data would allow to support commodity risk assessment for this pathway which may need to be regulated (and which is already regulated in some countries, e.g. Israel).

Expected output: data to support pest risk assessment.

The organizations to involve and activities to be covered in this collaboration will be agreed upon in Spring 2020.

Disinfectants against quarantine viruses and viroids

Short description: The project should gather information on disinfection of tools and greenhouses surfaces against a number of viruses and viroids, and if necessary, perform additional experiments to identify effective disinfection protocols.

Expected output: validated protocols on the use of disinfectants against viruses and viroids.

The organizations to involve and activities to be covered in this collaboration will be agreed upon in Spring 2020.

Preparedness in biological control of priority pests

Short description: The use of biological control agents for pest species is often initiated in response to negative impacts (e.g. high economic damage/yield losses). Recently, New Zealand assessed and approved the release of the egg parasitoid Trissolcus japonicus against Halyomorpha halys before the arrival of the target pest. The project should conduct literature reviews on priority pest species and their potential for biological control for countries/regions where the pest is not yet present or where it is but only causing low levels of damage. Additionally, a biocontrol network could be established to facilitate technology transfer and information sharing.

Expected output: knowledge, development of a network to share information on biocontrol.

The organizations to involve and activities to be covered in this collaboration will be agreed upon in Spring 2020.
