Evaluation of barley yellow dwarf virs under conservation tillage practices in winter wheat
Bibliographic record
Abstract
Barley yellow dwarf virus (BYDV) (Luteoviridae) is the most damaging viral disease of cereals worldwide. Due to increased adoption of conservation tillage practices in winter wheat production in south-western Ontario, it was suspected that BYDV incidence may have increased due to reduced destruction of volunteer wheat and earlier planting dates. It was hypothesized that volunteer wheat could serve as a reservoir for cereal aphids that transmit BYDV and provide a 'green bridge' to autumn sown winter wheat. Over two years of study, the incidence of BYDV in winter wheat and fields containing volunteer wheat was assessed and the most prevalent serotype(s) were determined. The most abundant vector species was determined as well as the seasonal dispersal patterns of cereal aphids by monitoring field populations and catches in suction air and elevated pan traps. Chloronicotinyl seed treatments were evaluated for their efficacy in controlling cereal aphids and BYDV.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
