P2005-RT

Polar pesticides in soybean flour

For risk assessment of glyphosate, the sum of glyphosate, AMPA, N-acetyl-glyphosate and N-acetyl-AMPA should be considered. Furthermore, according to a reasoned opinion of EFSA (EFSA Journal 2018; 16(5):5263) a residue definition of glyphosate, AMPA and N-acetyl-glyphosate, expressed as glyphosate is discussed with respect to soybeans.
Diquat and paraquat are commonly applied to soybeans and are thus included in the ring test P2005-RT. 

The laboratories are free to choose to take part in both modules (module 1: glyphosate and metabolites and module 2: diquat, paraquat) or to choose one of the modules.

Parameters

Module 1

glyphosate, N-acetyl-glyphosate, AMPA, N-acetyl-AMPA, glufosinate
