Specific objectives: a to investigate Subsurface Water Retention Technology SWRT and biochar-compost mixture inter-row application for improving soil water holding capacity and reducing the competition between grape vine and cover crops for water and nutrients.

This study is working towards the long term goal of finding effective management strategies of the major grapevine trunk disease GTD pathogens found in British Columbia, as well as those that may be imported in nursery material. Epidemiological studies and implementation of DNA-based molecular diagnostic tools for a rapid and precise detection of all fungal species associated with GTD will facilitate the effective investigation of control strategies.

The sustainability of the wine grape industry also requires the importation of healthy vines as part of a practical disease management strategy. Therefore, the development of a comprehensive disease control strategy will be investigated for both commercial vineyards and nurseries. In white wines, the wine aroma plays a major role in determining wine quality and economic value.

In many grape varieties cultivated in BC, the aroma makeup is built in the vineyard where key aromatics accumulate in the grapes.

Irrigation and crop size adjustments are two main strategies that growers have adopted to manage fruit ripening and composition. Both strategies have been largely used as a tool to improve the composition of red grapes but very limited information is available on the impact of these strategies on the accumulation of aromatics in white grapes.

This project aims to evaluate the effect of deficit irrigation and crop size adjustment strategies on the concentration of aromatics in white grapes and wines. The goal is to develop an irrigation and crop size adjustment strategy that maximizes the level of aromatics produced in white grapes cultivated in BC while minimizing water demands.

The BC Wine Grape Council has participated in funding research at UBCO to develop methods to identify regionally-specific molecules involved in smoke residues so as to allow producers to predict degree of smoke taint in wine from the chemical composition of smoke-exposed berries, thus enabling them to minimize economic and quality impacts of smoke exposure.

We feel this work has significantly contributed to the body of knowledge concerning the chemistry of smoke taint in wine. What we have found from past experience and literature search is that smoke taint in wine arises from very close exposure of vines to wildfire at very specific stages in berry development.

Currently we do not expect to see significant widespread impact from the wildfires. New vineyard irrigation regimes will be developed that simultaneously enhance environmental sustainability and fruit quality for winemaking.

The regimes will be tailored to selected rootstocks and will combine drip and sprinkler irrigation to conserve water, enhance the growth of floor vegetation to reduce pest and disease incidence, and promote a healthy soil microbial ecology.

This research activity will also establish large long-term research plots for demonstrating to industry the responses of Merlot and Chardonnay winegrapes to combinations of rootstocks, irrigation regimes, and mycorrhizal inoculations. Vineyard groundcover vegetation can influence the growth of grapevines by competing directly for water and nutrients, or conversely by providing nitrogen in the case of legumes. Selection of vineyard groundcover species with beneficial properties requires consideration of differences in growth habit, drought tolerance, and the ability to withstand mowing and vineyard activities.

Previous research has shown that increasing plant diversity, particularly the presence of winter annual mustards in the vine rows in spring, contributes to the management of grape pests. Increasing use of drip irrigation and a desire to include flowering plants that provide shelter and alternative sources of food for beneficial insects favours the use of locally adapted native species, but little is known about their growth characteristics and suitability for the vineyard ecosystem.

This research will investigate the suitability of a variety of native and non-native groundcover species, assess their impact on populations of grape pests and beneficial insects, and evaluate their effects on vine growth and fruit quality.

A conceptual model developed by PARC researchers see below has formed the basis of GIS research to find viticultural and enological practices that optimally interact with terroir to maximize vineyard performance. These include the natural ecology within and surrounding vineyards as components of terroir; and environmental sustainability in equal partnership with economic sustainability as performance goals of viticulture and enology management.

In previous GIS research conducted by PARC researchers a database was developed for Okanagan and Similkameen valley vineyard varietal blocks and their associated terroir and viticultural characteristics Bowen et al. Through analyses of these data, growing regions sub-appellations were defined and influences of management practices and terroir on fruit and wine quality were revealed.

Other outputs of the research included definitions of varietal suitability to growing regions; effects of terroir and management on fruit composition and wine flavour and aroma; and provision to growers of vineyard maps overlain with soil characteristics to guide irrigation and fertility management Bowen A demonstration of distinct differences in flavour, aroma and mouth-feel of Merlot wines due to region of origin was one of the first scientific analysis worldwide clearly demonstrating terroir influences on wine sensory quality.

Develop crop production systems to enhance producer profitability by decreasing risk, decreasing cost of production and improving overall economic and environmental sustainability. Develop management practices and standards to promote plant health are developed.

This project examined several aspects of grapevine nutrition that impact the health of the vine, the quality of the wine and the quality of the environment. Methoxypyrazine MP in minute quantities can greatly affect the vegetative character and overall quality in some wine grape varieties. Results from the past three years show that higher rates of nitrogen and the timing of applications impact MP levels in Cabernet sauvignon and Sauvignon blanc, two important varieties for the BC wine industry.

We found that higher rates of nitrogen applied early in the season result in higher levels MP. The primary pyrazine is IBMP which is a bell pepper aroma remains above sensory threshold levels to maturity. The effects of irrigation regimes combining different rates, frequencies and emitter densities were studied to find optimum regimes that lead to high fruit quality and water use efficiency while reducing excess stress and crop losses due to winter injury.

Experiments were conducted with Merlot and Pinot gris on coarse textured sandy soils. High frequency irrigation reduced vine stress while improving water use efficiency, and fruit quality by enhancing skin tannins and reducing berry pH while maintaining crop yields. Reducing the irrigation rate to a moderate deficit also increased water use efficiency but reduced crop yields, fruit soluble solids brix , juice TA and skin tannins, and increased juice pH.

The only benefit of the reduced irrigation treatment was a slight enhancement of berry anthocyanins. Reducing emitter density to give longer, deeper penetrating irrigations increased crop yields and water use efficiency but had no other effects.

Sensory analysis of wines made from Pinot gris showed that more frequent irrigation enhanced wine body and fruit flavour. We propose to: 1 evaluate the responses of four rootstock options to five combinations of Okanagan nematode species-populations, and 2 characterize the influences of compost soil amendments on the nematode-root interaction for resistant and susceptible rootstocks. The proposed research will be one component of a co-ordinated BC-Pacific Northwest regional collaborative research effort.

The overall goal of the collaboration is to better understand the pathogenicity of plant parasitic nematodes found in vineyards in the region, extrinsic factors affecting their pathogenicity, and rootstock resistance. Recently, there have been reports of vines with poor vigour and weak growth, which may be a result of nutrient deficiency, compounded by overcropping.

Low vigour can also be a consequence of excessive root damage, resulting from soil nematodes. The effects of application and removal timing for polyethylene vine canopy enclosures sleeves was studied in two Okanagan Valley vineyards. Registration of new pesticides is required for the continued viability of the grape and wine industry in BC.

Many insecticides formerly used on grapes are no longer available, are ineffective, or cause outbreaks of secondary pests such as mites. Reliance on broad-spectrum, highly toxic insecticides also runs counter to the image that the B. During this two year study we will evaluate the efficacy of a number of new, reduced-risk insecticides e. Evaluation of oils also involves assessment of possible effects on vine growth or maturation of fruit.

Research will be conducted to determine interactions among environmental conditions soil and climate , irrigation and N fertilization levels, and canopy management methods that influence wine grape quality. The goal of the research is to determine whether a decline in canopy performance due to stress resulting from water and N deficits delays maturation and reduces fruit quality.

The research will be conducted at two or three commercial sites differing in climate and soil texture. Canopy growth and performance photosynthesis , and fruit microenvironment will be monitored over the growing season.
