Abstract

contribution to session I

Regulatory issues

Background: Soil or seed applied plant protection products (PPPs) aim at bringing the amount of active substance involved to the only parts of the plant that have to be protected. Despite a reduced exposure of non target organisms by this way, an exposure of honey bees through residues in pollen and/or nectar may not be excluded for substances that migrate towards the upper plant parts. Directive 91/414/EEC, related guidance documents and literature data were reviewed and discussed by a working group of the ICPBR (International Commission for Plant-Bee Relationships) with the aim to provide adequate guidance to proceed in a risk assessment in such cases.

Results: The review and expert knowledge collected within ecotoxicology, entomology and plant residue area allowed to identify the key parameters that trigger a risk assessment as well as basic hypotheses to consider in deciding for the experimentations required (laboratory, semi-field and field tests). A stepwise, tiered approach is proposed, which has been checked for its ability to discriminate substances that may pose a risk to bees from substances of low concern.

Conclusion: The present scheme is proposed to update the current EPPO risk assessment scheme with a special issue on systemic PPPs.

Keywords: risk assessment, honey bees, soil or seed treatments, systemic.
