Strawberry Green Petal Disease Pathosystem in Québec, Canada
Bibliographic record
Abstract
Abstract The emergence and re-emergence of pathosystems are expected to increase with ongoing climate change. Strawberry green petal disease (SbGP) is caused by phytoplasmas transmitted by two leafhopper species, Aphrodes bicinctus and Macrosteles quadrilineatus , in strawberry crops. In Québec, SbGP was frequently reported between 1950 and 1970. However, recent surveys (2012–2022) indicate an increased disease incidence in strawberry fields. While it is unclear whether this increase indicates a re-emergence or underreporting, understanding these pathosystem components can help clarify the underlying causes. This case study reviews the SbGP pathosystem, historical reports, and existing control measures, emphasizing the importance of ongoing and future research to address identified gaps. Although SbGP currently poses a limited economic threat, the interactions within the pathosystem could be exacerbated by warming temperatures, potentially leading to increased vector populations, altered phytoplasma development, susceptibility of strawberry plants, and consequently, severe outbreaks and a broader geographic distribution of the disease.

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.
