Crop border and mineral oil sprays used in combination as physical control methods of the aphid‐transmitted potato virus Y in potato
Bibliographic record
Abstract
BACKGROUND: The objectives of this work were to determine if the control of potato virus Y (PVY, genus Potyvirus, family Potyviridae) in seed potato could be improved by combining border crops and mineral oil sprays, and if the border crop acts as a barrier or a virus sink. RESULTS: Field tests over 3 years confirmed that mineral oils alone are an effective barrier to PVY, and showed that borders alone act as a PVY sink. Combining the familiar mineral oil and the more recent crop border methods was almost twice as effective in reducing PVY incidence as either one used alone. The combination provided consistently high PVY control compared with the variable and often lower level of control by either method alone. The contribution of the oil to PVY reduction was similar whether it was applied to the border, the center seed plot, or both. Oil application to the border alone should not affect efficacy and would help keep control costs down. CONCLUSION: Combining border and oil provided the best reduction in PVY incidence 3 years out of 3, providing producers with a tool to reduce year-to-year variation in the effectiveness of crop borders or oil sprays used separately.

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.
