Characterization of <i>Athelia rolfsii</i> associated with southern blight of pointed gourd ( <i>Trichosanthes dioica</i> ) in India
Bibliographic record
Abstract
Pointed gourd (Trichosanthes dioica Roxb) is a perennial cucurbitaceous vegetable popular in the eastern and northern parts of India. In July 2018, an occurrence of southern blight disease was observed in a pointed gourd crop grown in Odisha state located in the eastern part of India. The typical symptoms included angular necrotic patches and disintegration of leaf tissues with the vein and veinlet intact, exhibiting a diagnostic netted pattern of veins. Silky white, fan-shaped mycelial growth with sclerotial bodies was observed on the lower surface of infected leaves. Eventually, the infected leaves dried up, leaving several bare patches in the field. Associated fungi were isolated, which resembled the reference strain Athelia rolfsii based on colony characteristics. Phylogenetic analysis of the internal transcribed spacer of rRNA gene region confirmed that the isolates were A. rolfsii. Pathogenicity was successfully proved on detached leaves as well as on potted pointed gourd plants. On the basis of symptoms associated with the disease, fungal morphology, molecular identification, and pathogenicity tests on host plants, the causal fungus was identified as A. rolfsii. This is the first report of southern blight disease caused by A. rolfsii on pointed gourd in India.

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.
