High spatial resolution airborne imagery was acquired in California's Napa Valley in 1993 and 1994 as part of the Grapevine Remote sensing Analysis of Phylloxera Early Stress (GRAPES) project. Investigators from NASA, the University of California, the California State University, and Robert Mondavi Winery examined the application of airborne digital imaging technology to vineyard management, with emphasis on detecting the phylloxera infestation in California vineyards. Because the root louse causes vine stress that leads to grapevine death in three to five years, the infested areas must be replanted with resistant rootstock. Early detection of infestation and changing cultural practices can compensate for vine damage. Vineyard managers need improved information to decide where and when to replant fields or sections of fields to minimize crop financial losses. Annual relative changes in leaf area due to phylloxera infestation were determined by using information obtained from computing Normalized Difference Vegetation Index (NDVI) images. Two other methods of monitoring vineyards through imagery were also investigated: optical sensing of the Red Edge Inflection Point (REIP), and thermal sensing. These did not convey the stress patterns as well as the NDVI imagery and require specialized sensor configurations. NDVI-derived products are recommended for monitoring phylloxera infestations.

A historical investigation into the mysterious bug that wiped out the vineyards of, first, France and then Europe in the 1860s -- and how one young botanist, who had served an apprenticeship at Kew Gardens, eventually 'saved wine for the world'. Bordeaux, inexplicably began to wither and die. Panic seized France, and Jules-Emile Planchon, a botanist from Montpellier, was sent to investigate. Magnifying glass in hand, he discovered the roots of a dying vine covered in microscopic yellow insects. The tiny aphid would be named Phylloxera vastatrix -- 'the dry leaf devastator'. Where it had come from was utterly mysterious, but it advanced with the speed of an invading army. As the noblest vineyards of France came under biological siege, the world's greatest wine industry tottered on the brink of ruin. The grand owners fought the aphid with expensive insecticide, while peasant vignerons simply abandoned their ruined plots in despair. Within a few years the plague had spread across Europe, from Portugal to the Crimea. the parasite had accidentally been imported from America. He believed that only the introduction of American vines, which appeared to have developed a resistance to the aphid, could save France's vineyards. His opponents maintained that this would merely assist the spread of the disease. Meanwhile, encouraged by the French government's offer of a prize of 300,000 gold francs for a remedy, increasingly bizarre suggestions flooded in, and many wine-growing regions came close to revolution as whole local economies were obliterated. Eventually Planchon and his supporters won the day, and phylloxera-resistant American vines were grafted onto European root-stock. Despite some setbacks -- the first fruits of transplanted American vines were universally pronounced undrinkable -- by 1914 all vines cultivated in France were hybrid Americans. of one of the earliest and most successful applications of science to an ecological disaster.
