Abstract A method is described for determining residues of an experimental herbicide, based on Lenacil (3‐cyclo‐hexyl‐5,6‐trimethyleneuracil) in soil and sugar beets. The procedure is based on the gas chromatographic measurement of Lenacil after extraction from the substrate with an alkaline solution and subsequently partitioned into an organic solvent. Intermediate cleanup steps are required. The sensitivity of the method is about 0·04 ppm based on a 25‐g sample, with an average recovery of better than 80%.
