Abstract
Field Occurrence and epidemic dynamics of alfalfa common leaf spot (Pseudopeziza medicaginis) were investigated in the exotic and native varieties at different fields and clipping times. The results showed that the occurrence degree of alfalfa common leaf spot was different with varieties, but the trends of the disease were the same. Within 18 varieties, the highest disease incidence and index were found on Canadian DY and winter hardy alfalfa, the lowest ones found on Guyuan alfalfa, and those on American Zahua alfalfa, WL323, and Zhongmo No. 1 were the middle degree. The development of the disease exhibited a S type curve in seasonal dynamics. The disease began from the end of May to early June, and reached up to exponential phase in July and August, and declined in September. The increased velocity of the disease was the highest in the first and middle ten days of August, and the last ten days of both July and August took second place. The key period of the disease was in July and August. Clipping methods also affected the occurrence and development of the disease. Therefore, rational clipping methods at appropriate time were the available measures to decay, relieve, and control the alfalfa common leaf spot.

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
