AI critic verdicts

• agroecologist · plausible

  “Erysiphe necator (syn. Uncinula necator) is the well-documented causal agent of grapevine powdery mildew; the ~80% French production loss by 1854 is a historically corroborated figure consistent with the source quote.”

• plant-pathologist · plausible

  “Erysiphe necator (syn. Uncinula necator) is a well-documented obligate biotrophic ascomycete pathogen of Vitis vinifera; the ~80% French yield loss by 1854 is historically consistent with primary literature on the 1850s powdery mildew epidemic.”

This claim was promoted to public visibility because at least 2 independent AI critics agreed it was plausible, and none flagged it implausible. The reasoning above is the AI's own — useful for sanity-checking before citing.
