Inside the book

The pamphlet opens with the Chamber's cri d'alarme, followed by three formal petitions to the Minister: the publication of an official summary of the phylloxera question, the increase of the proposed reward to one million francs, and legal protection for insectivorous birds as natural enemies of the pest. The Première partie, presented as a practical handbook, traces the origin and spread of the epidemic (rom its first observations around 1863 in England and the Var to its appearance in the Bordeaux vineyards about 1866) before describing the characteristic symptoms of the disease and the insect's complex life cycle in its gall-forming (gallicole) and root-feeding (radicicole) stages, both wingless and winged. A substantial chapter reviews the full range of contemporary remedies, from cultivation practices, fertilizers, drainage, and American vines to traps, birds, vineyard flooding, and chemical treatments. The author's constant refrain is the need for immediate intervention: isolate the infected vines, expose the roots to a depth of 30-40 cm, and irrigate with pentasulfure de chaux. The Deuxième partie moves from the vineyard to public policy, arguing for a national phytosanitary framework that anticipated the French law of 15 July 1878, and illustrating how the struggle against phylloxera had become as much a matter of legislation and commerce as of viticulture itself.
