Abstract

fetched live from OpenAlex

METHODS: The presence of Sotrytis cinerea and Sclerotinia sclerotiorum, the causal agents of blossom blight, in alfalfa flowers was assessed in Alberta (AB), Saskatchewan (SK) and Manitoba (MB). Seed production fields in the Peace River region of northern AB and in MB were examined in late July. In SK, fields were assessed in mid-July and again in early August. In southern AB, visual assessments of symptoms (florets fused and matted with fungal hyphae, or sclerotia in flowers) were made in mid- to late-August. In northern AB, five flower racemes were collected from each of six sites in each field. Four florets per raceme were plated onto acidified potato dextrose agar, without surface sterilization. In SK and MB, the oldest floret from each of four racemes, at each of 10 sites per field, was plated. The plates were incubated on the laboratory bench, and the incidence of pathogens was assessed after about ten days. Fungi were identified by microscopic examination of cultural characteristics, and some of the fungi were isolated into pure cultures for detailed examination. In southern AB, 100 racemes were rated at each of 10 sites in each field for blight symptoms. RESULTS AND COMMENTS: The mean incidence of B. cinerea in/on alfalfa blossoms in SK was greater than 60 % in July (Table l) , with a range from 3 % to 90 % in individual fields. The central region had above-normal rainfall, and substantial blossom blight was observed. The incidence of B. cinerea in the central region fell sharply in August, probably due to dry weather in July. Rainfall in spring and early summer in northern SK was well below

Not 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.
