An HPLC method to analyze imazamox residues in three soil types and in maiz
e plants is reported. The method allows for a rapid and quantitative detect
ion of imazamox both in soils and maize plants. The limit of detection was
10 ng. Recoveries in soils were satisfactory and varied from 82.2% to 99.5%
, depending on soil type and initial concentration, while in plants they we
re slightly lower but still satisfactory. Its reproducibility and the accur
acy make this method a selective and sensitive tool for routine analyses.
