Abstract
Formulations of a strain of Bacillus subtilis AUBS-1 inhibitory to the growth of the damping-off pathogen, Pythium aphanidermatum, were developed for seed treatment. The formulations included a talc-based powder, lignite-based powder, lignite+fly ash-based powder, wettable powder, bentonite-paste, polyethylene glycol (PEG) paste and a water-dispersible tablet. Formulations were stored at room temperature for 2 years and frequently sampled to test their shelf life. Populations of bacteria in the formulations were stable for up to 2 years storage at room temperature (28°C). Viability of propagules in lignite, lignite+fly ash, bentonite paste, wettable powder and water dispersible tablet formulations was 100% for up to 1 year. However, the viability of propagules was significantly reduced in talc, wettable powder, PEG paste and tablet formulations beyond 1 year of storage. Seed treatment of tomato with these formulations resulted in effective control of damping-off caused by P. aphanidermatum, and also enhanced plant biomass under glasshouse and field conditions. Active rhizosphere colonization by the bacterium was observed on tomato plants grown from seeds treated with the above formulations.

Full frame distilled prediction
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
