Using a Roller to Apply Herbicides for Control of Brush Regrowth in Saskatchewan Pastures
Bibliographic record
Abstract
A carpet-covered roller was used to apply herbicides to control woody plant regrowth in established pastures in Saskatchewan, Canada. A 1.5% v/v solution of a 4:1 mixture of 2,4-D ((2,4-dichlorophenoxy) acetic acid]:picloram (4-amino-3,5,6-trichloropicolinic acid) controlled the above ground growth of several tree and shrub species fairly well, but regrowth from the roots or stem bases usually occurred the year after the year of treatment. Applying a 1.5% v/v solution of glyphosate [N-(phosphonomethyl) glycine] resulted in more individual plant death but less permanent damage to survivors than the treatment with 2,4-D: picloram. The machine worked fairly well but is probably best suited to treatment of small patches of brush at least one metre tall to minimize damage to the forage understory, and not more than two metres tall because of the physical obstruction to the passage of the machine by larger trees.

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.
