Re-emergence of <i>Tobacco streak virus</i> Infecting Soybean in the United States and Canada
Bibliographic record
Abstract
Tobacco streak virus (TSV) has an extensive plant host range, but until recently has not been a common problem in North American soybean. TSV is associated with bud blight and yield loss due to reduced plant height and density, and delayed seed development and plant maturity. TSV has been reported in recent years in Illinois, Iowa, Kansas, and Wisconsin, as well as Ontario, Canada. Presence of the virus was confirmed by ELISA. In an Iowa field with high incidence, regression analysis indicated a significant positive relationship between incidence and seed moisture. TSV is seed and pollen transmitted, as well as being spread by thrips. Increasingly variable weather creating favorable conditions for thrips may be facilitating the rise of TSV. The combination of increased incidence of TSV with associated potential for yield loss and few known management methods brings attention to the need for further research.

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.
