Conclusion on the peer review of the pesticide risk assessment for bees for the active substance thiamethoxam
Following corrections reported by Sweden and Greece in relation to some of the authorised uses of thiamethoxam as a seed treatment on sunflower, oilseed rape and sugar beet, the risk assessment for these uses, where relevant, have been revised to take into account the appropriate maximum application rates. As a consequence, the Conclusion has been amended as follows:
- Section 2.1, Risk from contamination of adjacent vegetation via dust drift (field uses): the HQ values were recalculated for oilseed rape and sunflower and the corresponding text in the section has been amended accordingly.
- Section 2.2, Risk via systemic translocation in plants – residues in nectar and pollen (including sublethal effects): the ETR values were recalculated for oilseed rape and sunflower and the related text in the section has been amended accordingly.
- Section 7, Overview of the concerns identified for the authorised uses of thiamethoxam: the relevant rows in the table reflecting the outcome of the risk assessment for the products CRUISER OSR in Sweden for oilseed rape (both application rates) and CRUISER 600 FS for sugar beet were removed; the outcome of the risk assessment for the product CRUISER 600 FS in Greece for sunflower has been amended to reflect the correct application rate and, as a consequence, the outcome of the acute risk assessment from dust exposure has been changed from “risk identified” (i.e. "R" in the overview table) to an “issue that could not be finalised” (i.e. "X" in the overview table). The outcome of the risk assessment for the other uses on sunflower and the uses of treated oilseed rape and sugar beet seeds remained unchanged.
- Appendix A, Summary of authorised uses for seed treatment and granules, the rows referring to the products CRUISER OSR in Sweden for oilseed rape (both application rates) and CRUISER 600 FS for sugar beet were removed; the entry for the product CRUISER 600 FS in Greece for sunflower has been amended to reflect the correct application rate.
The European Food Safety Authority (EFSA) was asked by the European Commission to perform a risk assessment of neonicotinoids, including thiamethoxam, as regards the risk to bees. In this context the conclusions of EFSA concerning the risk assessment for bees for the active substance thiamethoxam 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 thiamethoxam applied as a seed treatment 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.
