The Iberian viticultural regions are convened according to the Denomination of Origin (DO) and present different climates, soils, topography and management practices. All these elements influence the vegetative growth of different varieties throughout the peninsula, and are tied to grape quality and wine type. In the current study, an integrated analysis of climate, soil, topography and vegetat...

This study evaluated how the proportional area of natural habitat surrounding a vineyard (i.e. landscape diversity) worked in conjunction with crop vigor, cultivar and rootstock selection to influence biological control of the western grape leafhopper (Erythroneura elegantula Osborn). The key natural enemies of E. elegantula are Anagrus erythroneurae S. Trjapitzin & Chiappini and A. daanei Tria...

Vineyards were surveyed for grapevine leafroll-associated viruses and their insect vectors in New York State's Finger Lakes region in 2006-2008. Grape mealybug, Pseudococcus maritimus (Erhorn) (Hemiptera: Pseudococcidae), European Fruit Lecanium, Parthenolecanium corni (Bouche), and Cottony Maple Scale, Pulvinaria acericola (Walsh and Riley) (Hemiptera: Coccidae) were identified as vector speci...

Bois noir (BN) is an insect-transmitted grapevine yellows disease caused by phytoplasmas belonging to the stolbur subgroup 16SrXII-A. In Italy, increasing prevalence of stolbur phytoplasma strains in vineyards suggests progressive spread of the disease and potential for heavy impacts on the wine industry. In this study, we investigated the genetic diversity of stolbur phytoplasma strains in BN ...

Precision Viticulture is experiencing substantial growth thanks to the availability of improved and cost-effective instruments and methodologies for data acquisition and analysis, such as Unmanned Aerial Vehicles (UAV), that demonstrated to compete with traditional acquisition platforms, such as satellite and aircraft, due to low operational costs, high operational flexibility and high spatial ...

The use of commercial wine yeast strains as starters has grown extensively over the past two decades. In this study, a large-scale sampling plan was devised over a period of 3 years in three different vineyards in the south of France, to evaluate autochthonous wine yeast biodiversity in vineyards around wineries where active dry yeasts have been used as fermentation starters for more than 5 yea...

The objective of the research was to assess the outcomes on the spray patterns produced by the different feasible adjustments of two different air blast sprayers and one mist blower sprayer, commonly employed for treatments to Apulian “tendone” vineyards. The spray profiles of these machines and the respective refinements affected by the alteration of the available adjusting devices were evalua...

Yeasts associated with cocoa and coffee beans are genetically distinct. These populations have been created through the migration and mixing of populations associated with vineyards, trees in America, and the ancestral seat of this species in Far East Asia.
