Almond witches'-broom phytoplasma: a potential threat to almond, peach, and nectarine
Bibliographic record
Abstract
A lethal phytoplasma disease of almond, almond witches'-broom (AlmWB), spread rapidly in Lebanon, killing about a hundred thousand trees within 10 years. This phytoplasma was the first member of the pigeon pea group reported to infect stone fruits. Preliminary results of grafting experiments proved that AlmWB could be transmitted by grafting to almond, peach, and nectarine but not to apricot, plum, and cherry. The occurrence of this disease at altitudes ranging from sea level to about 1000 m makes it a major potential threat to almond, nectarine, and peach in the major stone fruit production areas. Using universal primers, nested polymerase chain reaction is normally required for detection; however, the new primers described here allow efficient detection from the first run of polymerase chain reaction.Key words: phytoplasma, almond witche's-broom, almond, stone fruits, Prunus spp., PCR detection.

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.
