Conclusion on Pesticides

Note: This scientific output, approved on 20 December 2017, supersedes the previous output published on 22 October 2008 (EFSA, 2008), confirmatory data published on 21 June 2013 (EFSA, 2013) for environmental fate and behaviour and ecotoxicology data.


The conclusions of the EFSA following the peer review of the initial risk assessments carried out by the competent authorities of the rapporteur Member State, France, and co-rapporteur Member State, Germany, for the pesticide active substance copper compounds are reported. The context of the peer review was that required by Commission Implementing Regulation (EU) No 844/2012. The conclusions were reached on the basis of the evaluation of the representative uses of copper compounds as a fungicide on grapes, tomatoes and cucurbits. The reliable end points appropriate for use in regulatory risk assessment are presented. Missing information identified as being required by the regulatory framework is listed. Concerns are identified.
