Info Session on Applications – Pesticides – Technical Meeting with Stakeholders on “EFSA Guidance documents on protected crops and soil degradation rate”

Around 80 stakeholders from Member States, industry, consultancies, academia and European institutions took part in a meeting to discuss two new EFSA guidance documents in the area of pesticides.

EFSA scientists and expert working group members presented two recently published guidance documents on protected crops and soil degradation. Presenters also gave an overview of the legal framework and explained the scientific approach and associated methodology of the guidance documents.

Each presentation was followed by a detailed question and answer session, which generated valuable discussions on how to apply particular aspects of the proposed methodologies. EFSA noted that the scientific methodology proposed in both guidance documents was generally accepted by participants. Several delegates also encouraged EFSA to develop further technical and scientific advice for certain aspects of these methodologies as part of future EFSA guidance documents.
