Prairie Response to Canada Thistle Infestation, and Native Forb Response to Aminocyclopyrachlor
Bibliographic record
Abstract
Prairie response to Canada thistle invasion was evaluated by comparison of forage yield between aminopyralid treated and non-treated infestations in North Dakota. In general, forage production was unaffected by Canada thistle in both grazed and wildland locations. The economic threshold was 37 stems m-2 for a treatment to be cost-effective. Canada thistle should still be controlled to improve overall flora quality. The susceptibility of 10 prairie forbs to aminocyclopyrachlor at 0, 35, 70, and 105 g ha-1 was evaluated in the greenhouse. Blue flag iris was tolerant and harebell was moderately tolerant to aminocyclopyrachlor. American licorice, prairie rose, purple prairie clover, and wild bergamot were moderately susceptible; however, plants may regrow in the field as some survived at 105 g ha-1. Azure aster, Canada goldenrod, great blue lobelia, and purple coneflower were very susceptible to aminocyclopyrachlor and likely would be eliminated in the field.

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.
