Andrew,
Though there may be some isolated instances in California, its effect is dwarfed by other issues such as Pierce’s disease and moth problems.
Phylloxera never went away, not sure I understand the point of that article.
“Vineyards in California and Oregon on alert as the pest that devastated Europe’s grapevines in the 1800s turns its sights on once-resistant America” – Seems like a headline from circa 1990, no? Or 1985?
Exactly. America was never resistant, unless you’re talking about native grapes.
