Thesis (MscAgric (Viticulture and Oenology))--University of Stellenbosch, 2009.<br>ENGLISH ABSTRACT: Little scientific information regarding the effect of different geological parent materials on grapevine performance is currently available in South Africa. This aspect is of special significance for the Helderberg area, where parent material may change from granite to shale over a short distance. This results in shale- as well as granite-derived soils often occurring within the same vineyard. The objectives of this study were to (i) quantify the nutritional status and other soil propertie

Abstract:

Pierceâ s disease (PD) is a vascular disease of grapevines caused by <i>Xylella fastidiosa</i> (Wells et al.) (<i>Xf</i>) which is transmitted by xylophagous insect vectors. PD infection in Virginia vineyards was thought to be isolated to southeastern portions of the state as there have been no reports of vine loss in western Virginia and cold winter temperatures experienced there limit the effects of the bacterium from year to year. Upward trends in winter temperatures have raised PD concern in the mid-Atlantic. My risk assessment study found PD symptomatic vines beyond the modeled bounda

Abstract:

Vineyards in the Eastern United States are often prone to excessive vegetative growth. In order to suppress excessive vine vigor, many viticulturists have employed cover cropping strategies. Cover crops provide a myriad of agronomic benefits, however they are known to compete with the vine for water and nutrients. Due to the widespread use of cover crops in Eastern vineyards, many vineyards experience nitrogen (N) deficiencies in both the vegetative vine tissue and yeast assimilable nitrogen (YAN) in the juice. Soil applications of calcium nitrate and foliar applications of urea were asses

The fermentation of grape must by the action of microbial species naturalised within the vineyard and/or winery environment, rather than the use of monoculture inoculation, is practiced within some sections of the wine industry.

Abstract:

Implementation of Sustainable Management Practices at Two California Central Coast Vineyards and Their Effects on Soil Fertility Dawn Michelle Stimson “Sustainable agriculture” has gained increased popularity in recent years. This study was conducted to determine the effects of sustainable management practices on soil fertility at two California Central Coast vineyards. The effects of cover crops (Erosion Control Mix - blando brome [Bromus hordeaceus], hykon rose clover [Trifolium hirtum All.], and zorro annual fescue [Vulpia mourns]), green waste compost (Forest Blend), and reduced tillage

Abstract:

The economic impact of frost on agriculture remains a global problem. It is a particular concern for the New Zealand wine industry, where the consequences of an unexpected spring frost can be disastrous. Marlborough is located in the north-eastern corner of the South Island and is the largest grape-growing region in New Zealand. The region is surrounded by complex mountainous terrain that gives rise to extremes of climate, particularly large spatial variations of minimum temperature and the frequent occurrence of spring frost. The high spatial variation of near-surface minimum temperature can

Abstract:

<p>Outbreaks of spider mites (Acari: Tetranychidae) in vineyards have been increasing with the expansion of the industry in Virginia. Only three effective acaricides are registered on grapes and as resistance begins to occur, control options are limited. Biological control of spider mites by inoculative or inundative releases of predatory mites has been tried on a wide range of crops including grapes. This project examined the feasibility of using <i>Neoseiulus fallacis</i> (Acari: Phytoseiidae) as a potential large-scale biological control agent in vineyards. Slide dip bioassays were cond

Abstract:

Thesis (MScAgric)--Stellenbosch University, 2003.<br>ENGLISH ABSTRACT: In the past it was very difficult to visualise the extent and distribution of variability in growth vigour within vineyards. The advancement of remote sensing technology has changed this however, establishing new methods to assess and manage variability. Even though the causes and effects of within-vineyard variability in growth vigour are complex, new technologies offer better ways of monitoring, researching and managing these factors. In addition to the possible benefits of aerial or satellite remote sensing, new me
