Abstract

fetched live from OpenAlex

Phoma herbarum Westendorp has been identified as a potential biological weed control agent (BWCA) for Taraxacum officinale Weber in turf. However, host and pathogen variables that influence the efficacy of this BWCA need to be identified to provide more optimal conditions for production and efficacy. In controlled-environment studies, 4-week-old T. officinale plants were significantly more susceptible to P. herbarum than were plants that were 6 and 8 weeks old, nonflowering but mature, budding, or flowering. Mycelial suspensions incited significantly more severe disease than conidia, and 5-day-old mycelial shake cultures incited significantly higher disease than 3-, 7-, 9-, 11-, or 13-day-old cultures. A concentration of 10 to 20% of mycelial fragments in potato dextrose broth (v/v) incited higher disease severity than 0, 40, 60, or 100%. These experiments identified several important host and pathogen variables that influence the efficacy of P. herbarum on T. officinale and established more optimal conditions for production and efficacy of this BWCA.Key words: biological weed control, bioherbicide, mycoherbicide, Taraxacum officinale, dandelion, Phoma herbarum.

Full frame distilled prediction

Teacher imitation

Not 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.
