Abstract
The occurrence of fusarium head blight (FHB) in oat in Canada is reviewed, and preliminary results of recent studies in Manitoba are presented. Fusarium head blight was common in oat crops surveyed in southern Manitoba in 2002 and 2003, but visually, only low levels were evident. Fusarium graminearum and F. poae were the principal fungal species recovered from affected kernels. Levels of Fusarium spp. and deoxynivalenol (DON) varied among oat cultivars tested for their reactions to FHB in field trials. Putative Fusarium-damaged kernels were also assessed, but their identification was equivocal. As such, evaluation of DON and F. graminearum appear to be the best means of determining general FHB levels in oat and reaction differences among oat genotypes. Compared with wheat and barley, oat was less affected by FHB and may be more resistant to the disease. Dehulled oats (groats), when processed, had much lower levels of DON compared with whole oats. Effective management of FHB, including incorporation of improved levels of resistance and use of cultural options is needed to minimize the impact of the disease and ensure the sustainability of the crop in the region. Fusarium head blight is a major (new) disease of oat in western Canada.

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
