Fusarium head blight pathogens isolated from fusarium-damaged kernels of wheat in western Canada, 1993 to 1998
Bibliographic record
Abstract
Survey results from 1993 to 1998 for fungi isolated from fusarium-damaged kernels of wheat are presented. There is compelling evidence that Fusarium graminearum has recently been spreading westward from southeastern Manitoba, replacing less pathogenic Fusarium species as the principal fusarium head blight (FHB) pathogen. This movement has been accompanied by increasing economic losses from the effects of FHB. Environmental factors such as a lower average daily temperature in June and July may be influential in limiting the damage from F. graminearum in the western prairies, where F. graminearum currently is rare. However, precipitation levels at anthesis equal to those in the areas presently affected by economic levels of FHB occur in many western crop districts, suggesting that precipitation levels during the period of anthesis will likely promote further westward spread of this pathogen. The potential role of infected seed as a mechanism for long-distance dispersal of F. graminearum is considered

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.
