PulvéLab: an experimental vineyard for innovation in precision spraying

Abstract

One of the ways to reduce the use of pesticides is to adapt their dosage to the needs of the plant by using variable rate technology for managing field spatial variability. The recent evolution of technologies in the field of robotics, mechatronics and new information and communication technologies is paving the way for the development and diffusion of innovative digital solutions for precision spraying in vineyards. The PulvéLab is a new project launched in 2018 by the research joint unit team ECOTECH (IFV-IRSTEA). This project aims to accelerate innovation in precision viticulture by offering public and private partners a dedicated vineyard estate of 10ha (Hérault, France) to (i) test, (ii) evaluate and (iii) demonstrate the performance of their innovative solutions in operational conditions. The spatial and temporal variations of the vineyard were finely characterized. This characterization has been carried out in partnership with suppliers of vegetation index mapping, either by proxidetection sensors (Lidar IFV-IRSTEA, ForceA, Greenseeker), by Unmanned Aerial Vehicles (VineView, Chouette, Fruition Science) or by satellite (ICV-Terranis Oenoview), in order to analyze how these indices can help to establish management zone maps for dose reduction. For instance, we combined a map of vegetation acquired by VineView and the Optidose® model to obtain a dose recommendation map. Plant protection products saving was estimated at bunch closure stage between 10 to 29% according to the disease pressure and to the spatial dose adjustment scale.

Monitoring the tawny port wine aging process using precision enology

AIM: Tawny Port wine is produced in the Douro Demarcated Region by blending several fortified wines in different aging stages. During the aging process in small wood barrels, the red wine color progressively develops into tawny, medium tawny, or light tawny.

The FEM grapevine breeding program: new registered varieties (mid-)resistant to the main ampelopathies

“Vinum debet esse naturale ex genimine vitis et non corruptum”. The Eucharistic wine must be made with pure grapes that must not be contaminated in any way. This is how wine was born in the monastery of the Augustinians, and that is how the genetic improvement of grapevine implemented over the decades at the Agricultural Institute of San Michele all’Adige (since 1874; Trentino – Italy) has been oriented to make the cultivation of grapes always more sustainable. This concept is still current and meets the worldwide urgent need of reducing the use of chemicals, under a climate crisis scenario. Since the beginning of the twentieth century, the varieties introduced in Trentino and the new cultivars produced by pioneer breeders have already embraced the principle of sustainable viticulture.

Preliminary study of the influence of ripening on the polysaccharide content of different red grape varieties

Grape skin has a barrier and protective function in grapes. Cell wall of grape skins is mainly composed of polysaccharides such as pectins, celulloses and hemicelluloses and structural proteins. Terroir, variety and changes during ripening can affect the content of polysaccharides in grapes. The aim of this study was to evaluate the content of polysaccharides (PS) in grapes along the ripening process. Three red grape varieties were studied: Garnacha (G), Tempranillo (T) and Prieto Picudo (PP).
