Stork’s bill (Erodium cicutarium (L.) L’Her. ex Ait) and hemp-nettle (Galeopsis tetrahit L.): a cautionary note for eastern Canada field crops
Bibliographic record
Abstract
Stork’s bill was observed for the first time in 2009, and again in 2010, in a 22-yr-old conservation tillage study at La Pocatière, Québec. Within a year, the species had spread from two to ten plots, with densities ranging between 100 and 232 plants m-2 in 2010 compared with ≤ 12 plants m-2 in 2009. Currently, stork’s bill is not a major agricultural weed in eastern Canada; it should therefore be monitored closely and acted upon rapidly to prevent its establishment and spread. The relatively high hemp-nettle density in no-till compared with tilled treatments in 2009 was attributed to a cultivation operation conducted exceptionally in no-till treatments, confirming the responsiveness of the species to tillage.

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.
