Review: Fusarium head blight of barley in western Canada
Bibliographic record
Abstract
Fusarium head blight (FHB), caused primarily by Fusarium graminearum, has rapidly become the most notorious disease of cereals in parts of western Canada. The situation in barley is particularly striking, for until 1993 FHB was not observed in the crop at all, but by 1996 it affected every barley field examined in Manitoba. The disease is largely responsible for the decline in acreage and the loss of markets for both malting and feed barley in the region. Several aspects of FHB in barley are examined for this review, beginning with an overview and description of symptoms and disease epidemiology. Differences in the expression of FHB in barley as compared with wheat, including causal species, infection period, symptoms, and resulting damage (yield and quality losses) are described. These have implications for disease management, including breeding for resistance. The latter is ongoing at several institutions and should result in cultivars with improved resistance to FHB in future. Until then, an integrated protocol for disease management must be implemented to minimize the threat of FHB for producers and the industry.

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.
