Abstract

Forty-eight wheat samples were analysed for chlormequat and glyphosate residues.

Residues of chlormequat were found in 44 of the 48 samples in the range 0.02 mg/kg to 0.5 mg/kg. None of the residues found exceeded the MRL set for chlormequat in wheat of 2.0 mg/kg.

Residues of glyphosate were found in 17 of the 48 samples in the range 0.1 mg/kg to 2.3 mg/kg. None of the residues found exceeded the MRL set for glyphosate in wheat of 5.0 mg/kg.

No residues of either pesticide were found in 3 of the 48 samples received, with residues of both pesticides found in 16 of the 48 samples received.
