Abstract In accordance with Article 6 of Regulation (EC) No 396/2005, the applicants Landesanstalt für Landwirtschaft und Gartenbau Sachsen‐Anhalt (LSA) and Dienstleistungszentrum Ländlicher Raum Rheinpfalz (DLR), respectively, submitted a request to the competent national authority in Germany to modify the existing maximum residue levels (MRL) for the active substance aclonifen in chives, parsley, celery leaves/dill leaves, thyme/savoury and in celeriacs/turnip‐rooted celery. The data submitted in support of the request were found to be sufficient to derive MRL proposals for all crops under consideration. Adequate analytical methods for enforcement are available to control the residues of aclonifen in high water commodities under consideration at the validated limit of quantification (LOQ) of 0.01 mg/kg. Based on the risk assessment results, EFSA concluded that the exposure to residues resulting from the use of aclonifen according to the reported agricultural practices is unlikely to present a risk to consumer health.
