Occurrence of <i>Erysiphe friesii</i> var. <i>dahurica</i> on purple buckthorn ( <i>Rhamnus purpurea</i> ) from Pakistan
Bibliographic record
Abstract
Leaves of purple buckthorn observed with powdery mildew symptoms were collected from the district Abbottabad, Khyber-Pakhtunkhwa, Pakistan during field tours from August to October between 2017 and 2021. Morpho-anatomical features and molecular phylogenetic analysis were used to identify the causal agent as Erysiphe friesii var. dahurica. Pathogenicity was confirmed on healthy leaves of Rhamnus purpurea in a glasshouse at 25°C with 75 to 80% humidity and after inoculation, white powdery colonies appeared after 7 to 10 days. The fungal colonies were checked for the confirmation of pathogen. Erysiphe friesii var. dahurica on R. purpurea is being described here as a new record for Pakistan and Rhamnus purpurea is a new host, reported for the first time.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
