The French stockbroker Gaston Bazille (1819-1894) Montpellier was also owner of large vineyards. At the local university he learned the Professor of Botany Jules Emile Planchon (1823-1888) know. The two were commissioned in 1868 together with the horticulturist Félix Sahut to investigate the cause of the mysterious vine-dying. The group began their investigations at the Château de Lagoy winery near St. Rémy. Within just two days they managed to identify the cause of phylloxera. Planchon gave her the apt name Phylloxera vastatrix, in German "devastating louse". At that time, it was still unclear that the pest had been introduced from North America in the last 10 to 15 years.
Bazille then struck at a congress in 1869/1870 Beaune as allegedly first before (but this is also awarded to others), French scions on American documents (Rhizomes) to graft, without at this time already the resistance the American vines to be sure. However, his contribution died away unheard, because when it became clear that the phylloxera with American wild vines had come to Europe, the French government had banned in a panic first reaction to introduce more American vines. Of course, that did not help, because the pest was already there. The finishing as a solution to the problem was recognized much later and widely applied. See the entire story below phylloxera,
