Abstract
The objective of this project was to assess the efficacy of a turf herbicide product developed by Suncor, Petro Canada at different application rates and volumes. The treatments were combinations of different rates and volumes of pre-emergent herbicide, as well as controls for a total of 10 treatments. All of the experimental treatments reduced the broadleaf weed cover as well as the Killex standard. The range in weed reduction was quite large, from 34% to 76%. Timing of the treatment application, late in the season, was likely a source of the relatively poor weed control, since the Killex treatments showed less than 50% reduction in weeds. Of the two weed species most common in the treatment area, control seemed to be significantly better for the dandelions than for the broadleaf plantain. There was no significant visible phytotoxicity of any treatments on the grass, though there was some reduction in canopy reflectance, which may indicate general stress to the vegetation in all treatments.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
