## Abstract

The conclusions of EFSA following the peer review of the initial risk assessments carried out by the competent authorities of the rapporteur Member State Finland and co‐rapporteur Member State Denmark for the pesticide active substance phenmedipham 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 phenmedipham as a herbicide on sugar beet/fodder beet. The conclusions were updated with regard to the endocrine disrupting properties and the genotoxicity assessment following a mandate received from the European Commission in January 2019 and its update in January 2024, respectively. 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.
