The biology of Canadian weeds. 117. <i>Taraxacum officinale</i> G. H. Weber ex Wiggers
Bibliographic record
Abstract
Taraxacum officinale G. H. Weber ex Wiggers (dandelion, pissenlit officinal) is a perennial weed occurring in parks, gardens, pastures, orchards, roadsides, vegetable gardens, agricultural crops and horticultural crops. A common weed worldwide, it was originally introduced from Eurasia and now occurs in every province of Canada. It is an aesthetic problem during flowering and seed production, interrupting turfgrass uniformity and density; it reduces yields of agricultural crops; it causes slower drying of hay; its pollen is allergenic; and it acts as an alternative host for several pests and diseases. A number of herbicides are available for its control. Mechanical removal of T. officinale plants has limited success, due to the regenerative capacity of the long taproot. Insects, fungi, sheep and geese have been considered as biological control agents for dandelion. Key words: Taraxacum officinale, dandelion, weed biology, Canada.

How this classification was reachedexpand
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.
