EFSA clarifies neonicotinoid conclusions in light of new data

EFSA has made minor adjustments to its recent assessment of the risks to bees from pesticides containing the neonicotinoid active substance thiamethoxam. The changes, which follow the submission of new information from two Member States, regard some uses of thiamethoxam as a seed treatment for sunflower, oilseed rape and sugar beet. However, the overall conclusions that EFSA reported on 16 January are unaffected.

EFSA’s risk assessment for the use of thiamethoxam on sunflower seeds in Greece has been revised after the Greek reporting authority advised EFSA that the application rate it submitted was too high. Syngenta – which manufactures the pesticide containing the active substance, Cruiser 600FS – confirmed that the data it sent to the Greek authority was inaccurate. For the use of treated sunflower seeds authorised in Greece, the outcome of the acute risk assessment from dust exposure has therefore been changed from “risk identified” to an “issue that could not be finalised”.

Kemi, the Swedish Chemicals Agency, has also advised EFSA that it mistakenly submitted data for two pesticides – Cruiser 600FS and Cruiser OSR – that are not authorised for use in Sweden. The references to these two products have been removed from the risk assessment.
