Susceptibility of various potted begonias to<i>Fusarium foetens</i>
Bibliographic record
Abstract
Fusarium foetens was recently reported on greenhouse Hiemalis begonia (Begonia × hiemalis Fotsch) in Canada, causing disease symptoms which consist of a dull green leaf colour, wilting, and vascular necrosis. During our greenhouse trials, a concentration of 100 conidia mL−1 added to the growing substrate was sufficient to cause severe disease symptoms. F. foetens symptoms were observed as early as 2 weeks after inoculation, for highly susceptible Hiemalis begonia cultivars (i.e. ‘Berseba’ red, ‘Golden Edith’ yellow and red, ‘Rainbow Spectrum’ white, ‘Berseba’ hot pink). Disease symptoms were observed 3 weeks following inoculation for moderately susceptible Hiemalis begonia cultivars (i.e. white ‘Netja’, ‘Binos’ pink, ‘Batik’ orange, ‘Solenia’ velvet red, ‘Rainbow Spectrum’ pink chablis and ‘Netja’ dark pink), and after 4 weeks for slightly susceptible cultivars (i.e. ‘Rainbow Spectrum’ and ‘Rainbow Spectrum Vivian’). The Hiemalis begonia cultivar ‘Rainbow Spectrum Camilla’ was ranked as moderately resistant. Other begonia types such as Rex begonia hybrid (Begonia rex-hybrid Putz.), Fibrous begonia (Begonia semperflorens Hook.), and Tuberous begonia (Begonia tuberhybrida Voss), which exhibited symptoms 12 weeks following F. foetens inoculation, were considered resistant. Additional ornamental species (i.e. petunia ‘Polo Rose Flare’, impatiens ‘Balfieplos’ and poinsettia ‘Prestige’) inoculated with F. foetens did not develop visible disease symptoms, suggesting that F. foetens may be relatively host specific to begonia.

How this classification was reachedexpand
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.
