Can a general residue definition be proposed for primary crops? | No |
Rotational crop and primary crop metabolism similar? | Yes (tentative) |
Residue pattern in processed commodities similar to residue pattern in raw commodities? | Not applicable (chronic exposure is lower than 10% of the ADI) |
Plant residue definition for monitoring (RD‐Mo) | paclobutrazol (sum of constituent isomers) (limited to oilseeds, tentative for fruit crops) |
Plant residue definition for risk assessment (RD‐RA) |
RD – risk assessment 1: paclobutrazol (sum of constituent isomers) (limited to oilseeds, tentative for fruit crops) RD – risk assessment 2 (provisional): a separate risk assessment needs to be carried out for the triazole derivative metabolites (TDMs). This is foreseen in the framework of the on‐going assessment of the confirmatory data for triazole compounds and TDMs |
Conversion factor (monitoring to risk assessment) | Not applicable |
Methods of analysis for monitoring of residues (analytical technique, crop groups, LOQs) |
LC–MS/MS (EFSA, 2010):
HPLC–MS/MS (Italy, 2017a):
LC–MS/MS (EURL, 2017):
|
a.s.: active substance; DAT: days after treatment; PBI: plant‐back interval; ADI: acceptable daily intake; HPLC–MS/MS: high‐performance liquid chromatography with tandem mass spectrometry; LC–MS/MS: liquid chromatography with tandem mass spectrometry; LOQ: limit of quantification.
