Viticulture Session at Enoforum Web Conference 2021
The program of the Enoforum Web Conference will be divided into the following thematic sections: VINEYARD, GRAPE, CELLAR and WINE.
Speakers in the Viticulture session at the Enoforum Web Conference
The research papers selected by the International Scientific Committee for the VINEYARD session form 4 major thematic blocks: rootstocks and new varieties, pathogen defense, effective and low-impact vineyard treatments, precision viticulture and decision support systems.
Gabriela De Lorenzis will present a study of the genetic characterization of a large collection of rootstocks and a of other non-vinifera accessions, preserved at the University of Milan. Anne-Sophie Spilmont of IFV will demonstrate the potential of X-ray tomography, commonly used in medicine, as a tool to assess the quality of graft firmness in grafted vines. Rocio Gil Munoz of the Murciano Institute of Agribusiness Research and Development will illustrate how new hybrids meet new consumers’ demand for wines with lower alcohol content and greater freshness.
Flavescence dorée, downy mildew, Botrytis cinerea and wood pathogens still pose major challenges for modern viticulture. How the antifungal properties of stilbenic extracts could protect grapevine plants from Botrytis cinerea will be illustrated in research by Gicele Sbardelotto De Bona of the University of Padua, while Giuseppe Carella of the University of Florence will evaluate the use of microorganisms against wood pathogens. Nadia Bertazzon from CREA will present some of the mechanisms responsible for the different susceptibility to Flavescenza dorata of grapevine varieties, and Silvia Toffolatti from the University of Milan will report on the discovery of unique traits of downy mildew resistance in an oenological cultivar from the V. vinifera domestication center.
One way to reduce the use of pesticides is to adapt their dosage to the needs of the plant, using variable rate technology to manage spatial variability in the field. Xavier Delpuech of IFV will introduce the PulvéLab project, which aims to accelerate innovation in precision viticulture. Tara Southey of Stellenbosch University will expose how an online spatial decision support system can be useful for the wine industry.
New regulations for organic viticulture call for a significant reduction in copper-based treatments in the vineyard. At the conference, two Italian researchers, Giovanni Mian of the University of Udine and William Antonio Petrucci of CREA, will present their studies of different strategies to optimize and decrease copper applications. The effect of another treatment product based on the combination of zeolite and compost, studied under the LIFE ZEOWINE project, will be illustrated by Eleonora Cataldo from the University of Florence.
Mechanisms responsible for the different susceptibility of vine varieties to Flavescence dorée
Nadia Bertazzon – CREA Research Centre for Viticulture and Enology, Italy
Flavescence dorée (FD) is one of the most serious grapevine yellows diseases in Europe. Nadia Bertazzon of CREA (Italy) will present a comparative study of two different varieties, one highly susceptible to the disease and the other low susceptible with the aim of revealing the mechanisms responsible for the different susceptibility of grapevine varieties to FD.
Use of microorganisms in the disinfection/protection of organic rootstocks from wood pathogens
Giuseppe Carella – University of Florence, Italy
Giuseppe Carella of the University of Florence will evaluate the effects of microorganisms against wood pathogens, with the goal of reducing the use of fungicides throughout the production cycle. The research focuses particularly on the nursery sector where it aims to improve both the phytosanitary status of rooted cuttings and the quality aspect of nursery material.
Dual mode of action against Botrytis cinerea of vine shoot extracts
Gicele De Bona Sbardelotto – University of Padua, Italy
Crude extracts from Vitis vinifera shoots represent a natural source of stilbenic compounds with well-characterized antifungal properties. Research by Gicele Sbardelotto De Bona of the University of Padua will show how the application of stilbene extracts could protect grapevine plants from Botrytis cinerea.
PulvéLab: an experimental vineyard for innovation in precision spraying
Xavier Delpuech – Institut Français de la Vigne et du Vin, France
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 to manage spatial variability in the field. Xavier Delpuech of IFV (France) will present the PulvéLab project, which aims to accelerate innovation in precision viticulture.
Obtaining new varieties derived from Monastrell for the preparation of low-alcohol wines
Rocio Gil Muñoz – Instituto Murciano de Investigacion y Desarrollo Agrario y Alimentario, Spain
The main challenge faced by viticulture is adapting to new consumer demands, which require wines with lower alcohol content and greater freshness. Rocio Gil Muñoz of the Murciano Institute of Agribusiness Research and Development will talk about how new hybrids obtained from the Monastrell variety can help achieve this goal.
Study to optimize the effectiveness of Copper treatments for low-impact viticulture
Giovanni Mian – University of Udine, Italy
The purpose of the work by Giovanni Mian of the University of Udine is to determine the possibility of optimizing the efficacy of copper treatments for low-impact viticulture by using and evaluating the variation of copper coating on grapevine leaves and berries as a function of climatic conditions.
Copper reduction strategies in organic Sangiovese production.
William Antonio Petrucci – CREA Research Centre for Viticulture and Enology, Italy
New regulations for organic viticulture require a significant reduction in copper-based treatments in the vineyard. William Antonio Petrucci of CREA will present a possible strategy to minimize the number of copper applications in the vineyard.
TerraClim, an online spatial decision support system for the wine industry
Tara Southey – University Of Stellenbosch , South Africa
Climate projections for the future suggest challenging conditions for some wine-producing regions. For example, rising temperatures will likely shift vine phenology, ripening and harvest dates, and potentially affect grape quality and yield. Tara Southey of Stellenbosch University will show how an online spatial decision support system can help the wine industry counter climate change.
X-ray tomography: a promising tool to evaluate the selection of good quality grafted vines
Anne-Sophie Spilmont – Institut Français de la Vigne et du Vin, France
The production of grafted vines is a complex process, from grafting to final selection in nurseries. It is still difficult to assess the internal welding quality of grafted vines that reach the market. Anne-Sophie Spilmont of the IFV will demonstrate the potential of X-ray tomography, commonly used in medicine, as a tool to assess the quality of the weld of grafted vines.
From vine domestication center unique resistance characteristics against downy mildew
Silvia Laura Toffolatti – University of Milan, Italy
Cultivation of resistant V. vinifera varieties would be a sustainable way to reduce the damage caused by downy mildew and the impact of managing the disease, which comes with the economic, health and environmental costs of frequent fungicide applications. Silvia Toffolatti of the University of Milan will report the finding of unique traits of downy mildew resistance in a grape cultivar from the V. vinifera domestication center.
ZEOWINE: the synergy between zeolite and compost. Effects on vine physiology and grape quality
Eleonora Cataldo – University of Florence, Italy
The effect on physiology and quality characteristics in V.vinifera of a promising treatment product based on the combination of zeolite and compost, studied during the LIFE ZEOWINE project, will be illustrated by Eleonora Cataldo of the University of Florence.
Characterized one of the largest collections of grapevine rootstocks (non-vinifera)
Gabriella De Lorenzis – University of Milan, Italy
Microsatellite markers are a valuable tool to facilitate the management of germplasm collections and assess genetic diversity. Gabriela De Lorenzis will present the genetic characterization study of a large collection of 349 rootstocks and other non-vinifera accessions preserved at the University of Milan.
