Abstract
In Manitoba, plant bugs (Lygus spp. and Adelphocoris spp.) can be numerous in seed alfalfa crops in late August and September and are often the target of insecticide applications. From 2002 to 2004 in field plots in commercial fields, one or two insecticide applications in late August and September were made to reduce plant bug numbers relative to those in untreated check plots. Despite significant reductions in plant bug numbers in sweep net samples in sprayed plots, there were no significant effects of treatments on total seed yield per unit area, seed weight, percentage germination or percentage of hard seed. Relative to the check plots, reductions in plant bug numbers in insecticide-treated plots were not associated with increases in seed yield. Also, seed yield increases in insecticide-treated plots were not correlated with numbers of plant bugs immediately before insecticide application, and so it was not possible to estimate an economic injury level. The practice of applying an insecticide in August to control late-season plant bugs is economically unjustified within the range of plant bug numbers encountered in this study. Key words: Plant bugs, alfalfa seed, Lygus, Adelphocoris, economic impact

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
