The French stockbroker Gaston Bazille (1819-1894) Montpellier was also the owner of large vineyards. At the local university, he met the professor of botany Jules Emile Planchon (1823-1888). The two were commissioned in 1868 together with the gardener Félix Sahut to investigate the cause of the mysterious death of the vine. The group began their investigations at the Château de Lagoy near St. Rémy. Within just two days, they managed to identify phylloxera as the cause. Planchon gave her the appropriate name Phylloxera vastatrix, in German "devastating louse". At this point, however, it was still completely unclear that the pest had been introduced from North America in the past 10 to 15 years.
Bazille then struck at a congress in 1869/1870 Beaune supposedly the first one before (but this is also said to others), French scions in American documents (Rhizomes) without grafting at that time resistance of the American vines to be safe. His contribution went unheeded, however, because when it became clear that phylloxera had come to Europe with wild American vines, the French government, in a panicky first reaction, banned the introduction of further American vines. Of course, that was no use, because the pest was already there. The finishing the solution to the problem was only recognized much later and widely applied. See the entire story below phylloxera,
