Applications other substances

This concerns applications for co-formulants, safeners and synergists, and adjuvants. De assessment of these substances under the Regulation has not been fully specified as yet.

A Guidance Document for 'unacceptable co-formulants' (Article 27 Regulation 1107/2009) is in preparation at the EU level, but has not yet been adopted.

Safeners and synergists

A programme for safeners and synergists should be completed by the Commission, but is not yet available.
