Abstract
Phytopathogenic fungi are primarily responsible for destructive plant diseases that threaten food security. Biological control agents are generally based on their antibiotic characteristics. Nutrient competition is typical in microbes; however, the use of nutrient-competing antagonists for plant disease control remains underutilized. We found that ginseng root biomass selectively enriches soil pathogens and that biomass depletion prevents pathogen accumulation. We developed a method to capture specific ginseng root biomass-decomposing fungi from soils. We obtained three fungi via this method: one typical ginseng pathogen, Fusarium oxysporum , and two nonpathogenic fungi. These fungi do not display antibiosis to each other. However, nonpathogenic fungi significantly prevent ginseng root biomass-mediated accumulation of F. oxysporum . In addition, all three of these fungi inhibit the changes in the soil fungal community mediated by ginseng root biomass. To validate pathogen inhibition and community manipulation, we tested the effects of a commercial biomass-decomposing fungus, Aspergillus oryzae , on F. oxysporum accumulation and soil fungal community alteration after the addition of ginseng root mixture. The results support our conclusion that this method is simple and effective. Our results highlight an innovative application of nutrient-competing antagonists for plant disease control and a convenient protocol for screening for nutrient-competing antagonists.

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
