Metabolism and Fate of [<sup>14</sup>C]Ethametsulfuron-methyl in Rutabaga (<i>Brassica napobrassica </i>Mill<i>.</i>)
Bibliographic record
Abstract
The metabolism and fate of ethametsulfuron-methyl ¿methyl 2-[[[[[4-ethoxy-6-(methylamino)-1,3, 5-triazin-2-yl]amino]carbonyl]amino]sulfonyl]benzoate¿ in rutabaga were investigated. After 72 h, absorption and translocation of [(14)C]ethametsulfuron-methyl in rutabaga did not change for the duration of the study (50 days). Less than 4% of recovered radioactivity was present in the rutabaga root. Ethametsulfuron-methyl was metabolized through a proposed unstable alpha-hydroxy ethoxy intermediate that dissipated 3 days after treatment to two major metabolites, O-desethylethametsulfuron-methyl and N-desmethyl-O-desethylethametsulfuron-methyl, as determined by liquid chromatography-mass spectrometry. It was estimated that at a spray dose of 30 g of active ingredient ha(-)(1) and a harvest weight of 0.5 kg, the edible portion of the rutabaga root would contain no ethametsulfuron-methyl and approximately 1.3 ppb total of both identified metabolites. Residue analysis and toxicological assessment show that ethametsulfuron-methyl and its metabolites should pose little or no risk to consumers of rutabagas.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
