This study estimates the economic impacts of the Texas wine and wine grape industry on the Texas economy through each sector of commercialization from the vineyards to the final consumer. Survey data from the state's vineyards and wineries for 1996 is used to construct an in put-output model of the Texas economy and an industry impact framework using IMPLAN. Results show that the total core eco...

Grape canes are byproducts of viticulture containing valuable bioactive stilbenoids including monomers and oligomers of E-resveratrol. Although effective contents in stilbenoids are known to be highly variable, the determining factors influencing this composition remain poorly understood. As stilbenoids are locally induced defense compounds in response to phytopathogens, this study assessed the...

Almost half of the world’s vineyards are in the EU and the EU produces around 60% of the world’s wine. The EU is also the world’s most regulated wine market. In 2007, the European Union decided on a major reform of its wine policy, the so-called Common Market Organization (CMO) for wine. A crucial element was the abolishment of a system of planting rights to regulate planting of vineyards in th...

Background. Grapevine leafroll disease is one of the most widespread viral diseases in vineyards, affecting nearly all grape and wine regions in the world. Infection causes yield losses, ripening delays, and alters fruit chemistry, including lowering soluble solids and increasing titratable acidity. The viruses associated with leafroll disease are transmitted through propagation of infected mat...

The leafhopper Scaphoideus titanus is the vector of 'Candidatus Phytoplasma vitis', the causal agent of Flavescence dorée (FD) a key disease for European viticulture. In organic vineyards, the control of S. titanus relies mostly on the use of pyrethrins that have suboptimal efficacy. During 2016, three field trials were conducted to evaluate the efficacy of kaolin, orange oil, insecticidal soap...

The soil from three organically cultivated plots in Rioja Alavesa vineyards, specifically Lanciego (Álava, Spain), and the foliage of their vines were analyzed. aim this study was to determine differences grapevine quality between different aged vineyards. first 20 centimeters sampled leaves collected during growing season. results show that optimal did not differ reported values soils traditio...

Morphological identification and molecular study on the COI gene were simultaneously conducted on Anagrus Haliday 'atomus' group individuals collected in the field in Italy or supplied from a UK biofactory. Females were morphologically identified as A. atomus L. and A. parvus Soyka sensu Viggiani (=A. ustulatus sensu Chiappini). Alignment of COI gene sequences from this study permitted recognit...

Abstract The lack of refuge has been suggested as one the main factors affecting reptiles in intensive crops, but this theory not explored to any great extent. aim work is compare reptile abundance and species richness between traditional vineyards olive groves, test acceptance artificial shelter due its scarcity new woody crop. A total 288 transects were carried out (144 groves 144 vineyards) ...
