THE ETIOLOGY OF CORN SHEATH BLIGHT IN LIAONING PROVINCE
Bibliographic record
Abstract
Ninty three isolates of Corn Sheath Blight Pathogen from ecologically different regions in Liaoning Province (Shengyang, Dandong, Wafangdian,Changtu and Beining) were identified as Rhizoctonia solani AG1 IA by anastomosis formation with Japanese Standard isolates(AG1 AG6). The comparison of the pathogen esterase isoenzymes further demonstrated the above conclusion. The isolates of AG1 IA from corn sheath blight showed significant pathogenicity to corn and were determined as the virtual pathogen according to Koch's postulate. The pathogenicity of the 5 tested isolates collected from different regions was varied. Dandong RS 9501 was the most virulent one. Similarly, a significant difference existed among the 11 tested cultivars, of which Shengshi 28 showed highest level of resistance to the disease, while Shenshi 29 were the most susceptible one. The leap sheath (lower) at different growth stages showed different resistance to the disease with a decreasing trend from shooting to tasseling, and silking. This decreasing trend was more conspicuous on the 7th sheath than on the 3th sheath. Moreover, the biological characteristics of this pathogen were investigated in details in the following aspects: nitrogen and carbon requirement,VB1 dependence, temperature range, pH sensitivity, and the survival and saprophic colonizing ability.

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.
