Characterization of<i>Pythium</i>spp. from soil samples in Illinois
Bibliographic record
Abstract
Abstract Pythium root rot is widely distributed in major soybean (Glycine max) production areas throughout the world. There are many species of Pythium described on soybean and other crops, although not all species are pathogenic on these crops. The objectives of this study were to isolate and identify Pythium isolates obtained from field soils across Illinois and evaluate their pathogenicity on soybean seedlings. Soil samples were collected from 12 corn-soybean rotation fields in six Illinois counties. All isolates of Pythium were recovered through a baiting technique, identified to the species taxon using morphological and molecular techniques, and evaluated using an in vitro pathogenicity assay on soybean seedlings. Twenty-seven species of Pythium were identified, and P. cryptoirregulare, P. irregulare, P. sylvaticum, P. ultimum var. sporangiiferum and P. ultimum var. ultimum were highly pathogenic on soybean seedlings.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
