GAP: Good Agricultural Practice; OECD: Organisation for Economic Co‐operation and Development; MRL: maximum residue level.
*Indicates that the MRL is proposed at the limit of quantification.
NEU: Outdoor trials conducted in northern Europe, SEU: Outdoor trials conducted in southern Europe, Indoor: indoor EU trials or Country code: if non‐EU trials.
Highest residue according to the residue definition for monitoring.
Supervised trials median residue according to the residue definition for monitoring.
Conversion factor for risk assessment; median of the individual conversion factors at the supported PHI for each residues trial (unless otherwise specified).
MRLs are tentative because confirmatory methods for analysis of N‐acetyl‐glyphosate and AMPA are still required.
In case risk managers wish to restrict the RD to glyphosate and AMPA only, an MRL of 15 mg/kg would be sufficient to accommodate the new use on GAT rapeseeds.
In case risk managers wish to restrict the RD to glyphosate and AMPA only, an MRL of 2 mg/kg would be sufficient to accommodate the new use on GAT soybeans.
In case risk managers wish to restrict the RD to glyphosate and AMPA only, an MRL of 0.2 mg/kg would be sufficient to accommodate the new use on GAT maize.
