La r\u00e9gion du Rhin sup\u00e9rieur, abrite certains des vignobles les plus r\u00e9put\u00e9s d\u2019Europe mais ce patrimoine viticole est menac\u00e9 par les maladies du bois de la vigne<\/strong>. Des champignons d\u00e9truisent lentement les ceps de l\u2019int\u00e9rieur, sans sympt\u00f4mes apparents pendant des ann\u00e9es. Quand les signes deviennent visibles sur le bois ou les feuilles, il est souvent trop tard : les rendements diminuent, les ceps meurent et des parcelles enti\u00e8res doivent \u00eatre arrach\u00e9es et replant\u00e9es. Aujourd\u2019hui, la d\u00e9tection repose principalement sur l\u2019observation visuelle de feuilles d\u00e9color\u00e9es et de tronc n\u00e9cros\u00e9s. Cette m\u00e9thode, simple \u00e9conomique, reste limit\u00e9e : les sympt\u00f4mes ressemblent \u00e0 ceux provoqu\u00e9s par d\u2019autres facteurs de stress, comme la s\u00e9cheresse ou des carences nutritives et ne refl\u00e8te pas toujours l\u2019\u00e9tat interne du bois. Les interventions sont alors tardives et moins efficaces. Des techniques de pointe existent en laboratoire mais elles sont trop co\u00fbteuses et complexes pour un usage quotidien.<\/p>\n

 <\/p>\n

Face \u00e0 ce constat, le projet VitiSense d\u00e9veloppe deux outils innovants et pratiques pour les vignes<\/strong> : un capteur optique portable<\/strong>, qui mesure l\u2019activit\u00e9 photosynth\u00e9tique et la fluorescence des feuilles, afin de d\u00e9tecter tr\u00e8s t\u00f4t, un stress invisible et une I.R.M. portable adapt\u00e9e du domaine m\u00e9dical<\/strong>, capable de visualiser l\u2019int\u00e9rieur du cep et de rep\u00e9rer les zones n\u00e9cros\u00e9es. Ces appareils peuvent \u00eatre utilis\u00e9s seuls ou reli\u00e9s \u00e0 un r\u00e9seau de capteurs connect\u00e9s,<\/strong> pour permettre un suivi continu et des interventions cibl\u00e9es et ainsi r\u00e9duire les pertes et les co\u00fbts. L\u2019\u00e9lectronique de ses dispositifs sera encapsul\u00e9, afin de les rendre r\u00e9sistants aux intemp\u00e9ries.<\/p>\n<\/div><\/div>\n

\n

 <\/p>\n

Le projet r\u00e9unit un consortium transfrontalier et multidisciplinaire<\/strong> : des chercheurs en viticulture et en maladies de la vigne, de l\u2019universit\u00e9 de Haute Alsace<\/strong> et de l\u2019institut Julius K\u00fchn, des sp\u00e9cialistes en optique est en I.R.M. de l\u2019universit\u00e9 de Strasbourg et de la Fachhochschule Nordwestschweiz (FHNW), des experts en conception et en encapsulation des appareils de la Hochschule Furtwangen, ainsi que des partenaires industriels.<\/strong> Ensemble, ils con\u00e7oivent les prototypes, les testent en laboratoire puis dans les vignes et les rendent r\u00e9sistants aux conditions du terrain.<\/p>\n

 <\/p>\n

\u00c0 terme, VitiSense pr\u00e9voit de cr\u00e9er une start-up<\/strong> pour diffuser largement ces solutions. Les b\u00e9n\u00e9fices attendus sont multiples : des vignes plus saines, des pertes r\u00e9duites, une viticulture durable et la sauvegarde d\u2019un patrimoine r\u00e9gional exceptionnel.<\/strong><\/p>\n

 <\/p>\n

Le projet VitiSense est un projet de l\u2019Offensive Sciences de la R\u00e9gion M\u00e9tropolitaine trinational du Rhin sup\u00e9rieur, co-financ\u00e9 par l\u2019Union europ\u00e9enne via le programme Interreg Rhin sup\u00e9rieur, la R\u00e9gion Grand Est, le Ministerium f\u00fcr Wissenschaft, Forschung und Kunst du Land de Bad-Wurtemberg et le Ministerium f\u00fcr Wissenschaft un Gesundheit du Land de Rh\u00e9nanie-Palatinat.<\/h3>\n<\/div><\/div>\n<\/div>\n
