Abstract
Common bunt caused by Tilletia tritici and T. laevis remains an important disease of wheat, particularly in organic production where effective fungicides are not available. Acetic acid (AA), a potential organic seed fumigant, was evaluated for control of common bunt of wheat. The highly susceptible spring wheat cultivar Laura was inoculated with bunt spores and then fumigated with 2 and 4 g kg -1 AA vapour in 23 L chambers for 1 h at 20°C. Fumigation reduced field infection levels of common bunt in trials conducted at Lethbridge, AB during 2000, 2001, and 2003. The 4 g kg -1 rate was more effective than the 2 g kg -1 rate in reducing bunt infection, although both rates were as effective as Vitavax, the standard seed-treatment fungicide treatment. Some reduction in tiller numbers was associated with the AA treatments especially at the 4 g kg -1 rate. In vitro tests on artificial growth media showed that AA significantly decreased seed-borne mold contamination caused by several species of fungi. Acetic acid fumigation could be an important organic alternative to fungicides for control of common bunt. Key words: Covered smut, organic, seed treatment, stinking smut, vinegar

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
