Grape phylloxera is a root-feeding pest of grapevines. In Australia, phylloxera infested vineyards are subjected to quarantine restrictions and early detection remains vital for the timely implementation of post-outbreak quarantine protocols. Current detection methods rely on time-consuming ground surveying which involves detailed examination of grapevine (Vitis vinifera L.) root systems. Leaf ...

This study deals with the characteristics of throughfall produced by vine (Vitis vinifera L.) in one of the most common pedoclimatic conditions for grape production: a soil derived from marine sediments under a temperate Mediterranean climate, and located rather close to the seacoast. To distinguish the contribution of the plant from that of the atmospheric deposition, the throughfall was colle...

We know relatively little of the distribution of microbial communities generally. Significant work has examined a range of bacterial communities, but the distribution of microbial eukaryotes is less well characterized. Humans have an ancient association with grape vines (Vitis vinifera) and have been making wine since the dawn of civilization, and fungi drive this natural process. While the mol...

Modelling grape-vines from a two-dimensional image has a number of interesting problems which have to be overcome. Due to their growth patterns and the surrounding environment vines tend to grow in ways which result in a large number of occlusions from a single perspective, making identification difficult. In addition the presence of wires, posts and other foreign objects increase complexity. W...

Management with synthetic fungicides in the control of phytopathogens viticulture can cause environmental pollution and contamination residues grape cluster. The objective this study was to verify effect aqueous cinnamon extract on vitro vivo Plasmopara viticola catalase activity ‘Isabel Precoce’ vines. treatments used were: (ACE) at concentrations 0.12; 0.25 0.50% plus 0.25% vegetable oil (VO)...

Identification of species of Meloidogyne Goeldi, 1887 is fi-equently accomplished by using perineal patterns and morphometrics, but intraspecific populations are not easily distinguished. Chromosome numbers have been determined for 10 (6) of the 36 species of Meloidogyne which are currently recognized (1, 5). Four of these species have a range of chromosome numbers. This chromosome range permit...

Grapevine Pierce’s disease (PD) caused by the bacterium Xyllela fastidiosa (Xf) is a devastating vascular disease and is jeopardizing the grape and wine industries in the United States due to the PD susceptibility of most important commercial grape genotypes. In our recent study, we compared the PD-susceptible commercial grapevine genotypes with some PDresistant genotypes newly obtained from tr...

One of the most important operations in managed gardens is pruned grapes. For evaluate the effect of pruning short, medium, heavy on yield and yield components of Taif grapes, before and after the cold winter, in the years 2012 to 2013, A factorial experiment in a CRBD design with five replicates were performed on two factors. The first factor was the number of buds per stem and included the th...

Grape vines are cultivated in South Tangerang City, not only by farmers, but also members of a grape community. This research aimed 1) to describe the characteristics 2) show perspective grapes farmer, and 3) identify problems expectations carrying out cultivation City. Data collected through interview, observation sharing questionnaires. The number samples was determined proportionally 68 who ...

Abstract Leafroll is one of the most economically important viral diseases grapevines worldwide. Grapevine leafroll-associated virus 1 (GLRaV-1) and grapevine 3 (GLRaV-3) are prevalent in New York vineyards which low-density grape mealybug populations reside. A five-year experiment was performed a commercial ‘Cabernet franc’ vineyard Finger Lakes region to test influence spatial roguin...
