Abstract
In accordance with Article 6 of Regulation (EC) No 396/2005, Bayer SAS CropScience submitted an application to the competent national authority in Austria to modify the maximum residue levels (MRLs) for the active substance spirotetramat in pomegranates and various vegetables. On the basis of the Austrian evaluation report, EFSA concluded that for chicory roots and the crops belonging to the group of other root and tuber vegetables (except sugar beets) the data submitted in support of the MRL application are compliant with the data requirements; for pomegranate, a data gap was identified as regards the storage stability of residue trials. Adequate analytical enforcement methods are available to control the residues of spirotetramat in the plant matrices under consideration. Based on the risk assessment results, EFSA concluded that the proposed uses of spirotetramat on the crops under consideration will not result in a consumer exposure exceeding the toxicological reference values and therefore are unlikely to pose a consumer health risk.Entities:
