The impact of <i>Fusarium avenaceum</i> on lupin production on the Canadian prairies
Bibliographic record
Abstract
Narrow-leaved lupin has the potential to become an important pulse crop for the Canadian Prairies because of its high protein content and its climatic adaptation. However, cultivation in the region is constrained by seedling blight and root rot caused by Fusarium avenaceum, an endemic fungal pathogen that reduces seedling establishment and crop yield. This pathogen attacks a broad range of crop and non-crop plants in the region. It varies in colony morphology, in the aggressiveness of individual isolates toward different crops, and in genetic makeup. However, genetically and phenotypically similar isolates can occur over a broad geographic range and diverse isolates can be found in the same field. Despite this diversity, the sexual stage has been observed only rarely in nature. The deleterious effects of the pathogen can be mitigated by optimizing seeding depth. Temperatures that are near optimum for plant growth also reduced the effect of the pathogen, but few studies showed a consistent relationship between seeding date and damage by the pathogen. Fungicidal seed treatments have been shown to reduce the incidence of seedling blight. Although there is some variation in resistance to the pathogen, no completely resistant cultivars have been found under western Canadian conditions. Development of management strategies to mitigate the effects of fusarium seedling blight and root rot on lupin crops will make cultivation of this crop a much more attractive option for western Canadian producers.

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.
