Abstract
Botrytis cinerea and recently B. mali have been identified as important postharvest pathogens of apples in British Columbia (BC), Canada. Three isolates of both B. cinerea and B. mali were studied alone and in combination by inoculating mature ‘Gala’ apple fruit to compare their potential for causing decay. The fruit were incubated at 20°C for 6 and 8 days when lesion areas were calculated from lesion diameters. The lesion areas in apples inoculated with B. cinerea ranged from 1020 to 1514 mm 2 compared to 130 to 293 mm 2 for B. mali after 6 days. Primers developed to specifically amplify B. mali or B. cinerea were used in a PCR test to determine which Botrytis spp. was present in a particular lesion and estimate the quantity of each species. Relative fluorescent intensity of DNA extracted from apple tissue co-inoculated with B. cinerea + B. mali and amplified with the B. cinerea specific primer averaged 102.3%. On the other hand, the fluorescence produced by the B. mali primer averaged only 11.6% from the same DNA samples. These results confirmed that when both B. cinerea and B. mali are mixed together, B. cinerea becomes the dominant pathogen. Accepted for publication 2 July 2010. Published 20 September 2010.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
