The conclusions of EFSA following the peer review of the initial risk assessments carried out by the competent authority of the rapporteur Member State (RMS), France, for the pesticide active substance Bacillus amyloliquefaciens strain FZB24 and the considerations as regards the application for inclusion of the active substance in Annex IV of Regulation (EC) This is an open access article under the terms of the Creative Commons Attribution-NoDerivs License, which permits use and distribution in any medium, provided the original work is properly cited and no modifications or adaptations are made.The EFSA Journal is a publication of the European Food Safety Authority, an agency of the European Union.Peer review of the pesticide risk assessment of the active substance Bacillus amyloliquefaciens strain FZB24 The RMS provided its initial evaluation of the dossier on B. amyloliquefaciens strain FZB24 in the draft assessment report (DAR), which was received by the European Food Safety Authority (EFSA) on 13 April 2015. The peer review was initiated on 20 May 2015 by dispatching the DAR for consultation to the Member States and the applicant, Novozymes France.Following consideration of the comments received on the DAR, it was concluded that additional information should be requested from the applicant and that there was no need to conduct an expert consultation.In accordance with Article 12 of the Regulation, EFSA should adopt a conclusion on whether B. amyloliquefaciens strain FZB24 can be expected to meet the approval criteria provided for in Article 4 of the Regulation taking into consideration recital (10) The conclusions laid down in this report were reached on the basis of the evaluation of the representative uses of B. amyloliquefaciens strain FZB24 as a fungicide on cucurbits (cucumber, courgette and melon), potato and grapevine, as proposed by the applicant. Full details of the representative uses can be found in Appendix A of this report.The uses of B. amyloliquefaciens strain FZB24 according to the representative uses proposed result in a sufficient fungicidal efficacy against the target organisms.A data gap was identified for a search of the scientific peer-reviewed open literature on the active substance and its relevant metabolites.No data gaps were identified in the section identity, physical-chemical and technical properties and analytical methods.In the area of mammalian toxicology, a data gap and an issue that could not be finalised were identified to address worker risk assessment to secondary metabolites/toxins.In the area of residues and consumer exposure, the risk assessment cannot be finalised due to the possible production of secondary metabolites/toxins and EFSA can therefore not support the inclusion of B. amyloliquefaciens strain FZB24 in Annex IV of Regulation (EC) No 396/2005.The information available was insufficient to demonstrate that B. amyloliquefaciens strain FZB24 would respect the uniform principles criterion of not being expected to persist in soil in concentrations cons...
