On page 31 of the Conclusion the unit is changed from “mg a.s./100 kg granules” to “g a.s./100 kg granules” following an error reported by the applicant (Sumitomo Chemical Agro Europe) occurred in the unit for the conversion of the absolute residues of clothianidin into the amount per granules given in the study report Lindner, 2009 (study 34). The risk assessment remained unchanged.

Conclusion on Pesticides


The European Food Safety Authority (EFSA) was asked by the European Commission to perform a risk assessment of neonicotinoids, including clothianidin, as regards the risk to bees. In this context the conclusions of EFSA concerning the risk assessment for bees for the active substance clothianidin are reported. The context of the evaluation was that required by the European Commission in accordance with Article 21 of Regulation (EC) No 1107/2009 to review the approval of active substances in light of new scientific and technical knowledge and monitoring data. The conclusions were reached on the basis of the evaluation of the uses of clothianidin applied as a seed treatment or granules on a variety of crops currently authorised in Europe. The reliable endpoints concluded as being appropriate for use in regulatory risk assessment, derived from the submitted studies and literature data as well as the available EU evaluations and monitoring data, are presented. Missing information identified as being required to allow for a complete risk assessment is listed. Concerns are identified.
