Conclusion on the peer review of the pesticide risk assessment of confirmatory data submitted for the active substance lenacil
The conclusions of the European Food Safety Authority (EFSA) following the peer review of an initial risk assessment carried out by the competent authority of the rapporteur Member State Belgium, relating to the pesticide active substance lenacil are reported. The context of the peer review was that requested by the European Commission following the submission and evaluation of confirmatory environmental fate and behaviour data and an associated argumentation on the potential for effects / relevance of possible groundwater metabolites. The conclusions were reached on the basis of the evaluation of the representative uses of lenacil as a herbicide on sugar beet and fodder beet for the control of grass and broad-leaved weeds. The reliable endpoints concluded as being appropriate for use in regulatory risk assessment, derived from the available studies and literature in the dossier peer reviewed, are presented. The concern was identified, that the assessment of the relevance of potential groundwater metabolites, present in the leachate of relevant lysimeter studies, could not be finalised with the available information.
