Terms of Reference (as agreed by the Executive Committee in 2025)
Introduction
The ad hoc Panel on Resistance Risk Assessment met from 1997 to 2002 to prepare the EPPO General Standard PP 1/213 Resistance risk analysis (first approved in 1999 and revised in 2002, 2012 and 2015). Following the EPPO Workshop on the Interpretation and Use of the EPPO Standard on Resistance Risk Analysis (Bologna, IT, 2004-10-19/20), the ad hoc Panel was reconstituted to become a permanent Panel and the first version of the terms of reference for their work was drafted. The Panel met annually from 2006. In 2020, it was decided to rename the Panel as an Expert Working Group (EWG) to reflect the scope of the work which has clearly defined and limited tasks and the very specific expertise needed for its work. The EWG is, in particular, the body responsible for the establishment of a database on PPP resistance cases to be hosted by the EPPO Secretariat. The aim of the database is to share information on resistance cases among the responsible authorities for registration of plant protection products (PPP) across the EPPO region and between authorities and the agrochemical companies which apply for registration of their products.
Scope
The EWG assists the EPPO Panel on General Standards for efficacy evaluation to consider all aspects of data requirements for efficacy evaluation of plant protection products in relation to resistance issues and promotes harmonization to facilitate communication and regulatory data exchange on the resistance risk of plant protection products between authorities in different countries and between agrochemical companies (applicants) and authorities.
Tasks
- Further develop and maintain the EPPO database on PPP resistance cases,
- Analyse and validate the resistance cases reported by EPPO countries and ensure a coherent way of validation for the different resistance cases (e.g. for the different products). Validated cases will fill in the EPPO database on PPP resistance cases.
- Propose to the Panel on General Standards the need for revision of Standard PP 1/213 Resistance Risk Analysis and for preparation of other new Standards in the field of Resistance,
- Provide a platform for experts on PPP resistance to exchange information and experiences,
- Carry out specific additional tasks in the field of resistance,
- Inform the Panel on General Standards on its activities.
Membership of the Expert Working Group
The EWG is composed of the members of the former EPPO Panel on PPP Resistance. If more specific expertise is needed, a Call might be organised by the EPPO Secretariat. The Panel on General Standards will decide which experts are invited to join the EWG. EWG members should be selected on the basis of their expertise and should serve in an individual capacity.
Timing of meetings
The EWG normally meets annually. In between annual meetings, e.g. in order to prepare the annual meeting, teleconferences and e-mail consultations may be organized to facilitate rapid decision making.
Outcome
The resistance cases reported by EPPO countries will be made available to the users in the EPPO database on PPP resistance cases after validation by the EWG on Resistance to PPP. Advice and support on PPP resistance will be given to the Panel on General Standards.
