<i>Phytophthora ramorum</i>Werres, de Cock & Man in’t Veld, Sudden Oak Death / Encre des chênes rouges (Peronosporaceae)
Bibliographic record
Abstract
Phytophthora ramorum is the causal agent of sudden oak death, a disease that has killed millions of oak and tanoak trees in California and Oregon in the United States and of sudden larch death in the United Kingdom. Phytophthora ramorum was first detected in Canada in 2003 in nurseries in the Greater Vancouver area of British Columbia. Phytophthora ramorum is regulated by the Canadian Food Inspection Agency; nurseries where the pathogen is detected are placed in quarantine and all host plants are destroyed, at significant cost. This chapter reviews the biology and impact of P. ramorum and its management using monitoring and prevention, chemical control, and biological control. Fungal antagonists of P. ramorum from the genus Trichoderma and bacterial antagonists from the genus Bacillus show promise as biological control agents, but will likely need to be used as part of an integrated pest management strategy that includes prevention via sanitation and disinfection.

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.
