AI critic verdicts

• plant-pathologist · plausible

  “Plasmopara viticola is a well-documented oomycete pathogen of Vitis vinifera; its rapid post-1878 spread through French vineyards within ~5 years is historically corroborated.”

• agroecologist · plausible

  “Plasmopara viticola as an oomycete pathogen causing severe downy mildew on Vitis vinifera leaves, shoots, and berry clusters is well-established; the rapid 1878–1883 spread through French vineyards is historically documented and source quote supports the extracted claim.”

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.
