Abstract
In vitro experiments showed that sodium bicarbonate (SBC) was effective in inhibiting urediniospore germination and germ-tube elongation of Puccinia triticina, the causal agent of leaf rust on wheat. In vitro efficacy of SBC at 0.006 and 0.012 mol/L in inhibiting the spore germination was 64.1% and 100%, respectively. Two field experiments were conducted to investigate the efficacy of SBC alone or in combination with reduced rates of mancozeb in inhibiting leaf rust on wheat (Triticum aestivum). The results showed that the application of SBC at 0.12 or 0.24 mol/L, sprayed twice at 2-week intervals, significantly reduced the disease severity compared with a water-treated control in two experiments. In the first field experiment, the SBC treatment at 0.12 mol/L reduced disease severity from 11.4% to 2.2% that of the water-treated control. The efficacy of SBC was comparable with that of tebuconazole. Combining SBC with a reduced rate of mancozeb (25% of label rate) did not improve the efficacy of the SBC treatment in the first field experiment. In pot experiments conducted under controlled conditions, SBC at 0.12 and 0.24 mol/L significantly reduced disease severity. The efficacy of SBC at 0.24 mol/L was higher than that of the 0.12 mol/L treatment and caused no adverse effect on quantity and quality of wheat.

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 it
