Phylloxera and Death in the Vineyards: Case 11

By the 1870s a plant disease, Phylloxera, which attacks vine roots with resultant death of the vine had invaded California as it had done in virtually all the vineyards of Europe and elsewhere that grew Vinifera (European) grape vines.

Until understood and remedied vineyards everywhere were dying or dead.

The general remedy was and is to graft Vinifera onto native American root stock which is much more resistant to the disease. 

Intense experimentation here and in Europe led to a variety of Vinifera-American hybrids and root stocks that allowed revival of the vineyards. Note the devastation along the length of California.
