Flavescence dorée (FD) is a disease of grapevine transmitted by an insect vector, Scaphoideus titanus Ball. At present, no prophylaxis exists, so mandatory control procedures (e.g. removal of infected plants, and insecticidal sprays to avoid transmission) are in place in Italy and other European countries. We propose a model of the epidemiology of FD by taking into account the different aspects...

Humans have had a significant impact on the distribution and abundance of Saccharomyces cerevisiae through its widespread use in beer, bread and wine production. Yet, similar to other Saccharomyces species, S. cerevisiae has also been isolated from habitats unrelated to fermentations. Strains of S. cerevisiae isolated from grapes, wine must and vineyards worldwide are genetically differentiated...

This study investigated the effects of accumulated copper, on digestive epithelium height and percentage area, and on oocyte numbers of the snail Helix aspersa, in a vineyard where copper oxychloride is sprayed. The ultimate aim was to determine the usefulness of these cellular responses as biomarkers. Results showed that snails collected 2 months after fungicide application, had a significantl...

The wine is one of the most consumed drinks over the world, being subjected to falsification or adulteration regarding the variety, vintage, and geographical region. In this study, the influence of different characteristics of wines (type, production year, and origin) on the total phenolic content, total flavonoids content, antioxidant activity, total sugars content, pH, and 18O/16O isotopic ra...

The utilization of compost vineyard wastes as suppressive growing media against Fusarium wilt is a good alternative for the disposal and recycling of these organic wastes. Inoculation of biological control agents (BCAs) enhances the biocontrol activity of compost. In this experiment, vineyard compost was sampled at different stages during the composting process, rating the values of acceptabili...

In the context of vineyard leaf roughness analysis for precision spraying applications, this article deals with its characterization by computer vision and cloud computing techniques. The techniques merge feature extraction, linear or nonlinear dimensionality reduction techniques and several kinds of classification methods. Different combinations are processed and their performances compared in...

The use of UAV (Unmanned Aerial Vehicles) in precision viticulture leads to a more flexible and efficient approach vineyard management. Images from help determine the condition vineyard. Identification missing roots row by semi-automatic image classification its comparison with manual is goal paper. This study presents new methodology for segmentation vine gaps. RGB (Red-Green-Blue) images, mul...

• A pixel-based classification of esca-affected grapevine leaves was achieved by HSI. Multiple pre-processing and variable selection methods were tested using PLS-DA. Feature wavelengths identified automatic interval PLS methods. Asymptomatic belonging to vines successfully identified. NIR-HSI could detect foliar symptoms Esca disease complex. Precise reliable identification specific plant dise...

Tancik J., Seljak G. (2017): Occurrence of Scaphoideus titanus Ball and some other Auchenorrhyncha in the vineyards of western Slovakia. Plant Protect. Sci., 53: 95–100. A study of Auchenorrhyncha was carried out in 2014 and 2015 in 7 vineyard plots with different varieties and pest management strategies in the Nitra wine region and Lesser Carpathian wine region in western Slovakia. The aim of ...
