RELATIONSHIP BETWEEN STOMATA AND GRAPE COLD HARDINESS" HOW TO IDENTIFY SUPERIOR FROST TOLERANT GRAPES

The Establishment and Production Costs for Grapes in Ontario report is a collaborative effort between Grape Growers of Ontario and the Ontario Ministry of Agriculture, Food and Rural Affairs.  This report tries to reflect the management practices used by growers today.  Soil condition, cultivar selections, personal grower management decisions and the unique meso-climates of Ontario result in many different grower practices in training systems, pest management programs and fertilizer rates. 

The four grape cultivars in this document; Concord, Vidal, Chardonnay and Cabernet Franc represent Labrusca, French Hybrid and Vinifera types of grapes.

Growers can use the input costs as general guidelines to help identify strengths and weaknesses in their own businesses.

2015 BUD SURVIVAL SURVEY FOR NIAGARA AREA VINEYARDS

ONTARIO GRAPE AND WINE RESEARCH INC.

The objective of OGWRI is to enhance the profitability and sustainability of the Ontario grape and wine industry through directed and coordinated financing of research and development activities. Matthias Oppenlaender is Chair, and the Board of Directors has representatives from GGO, Wine Council of Ontario and Winery and Grower Alliance of Ontario. A technical committee establishes annual research priorities and reviews research project proposals. Projects must fall into one of three research pillars of viticulture, oenology and market research.

All completed projects and material is available at the Ontario Grape and Wine Research Inc.’s newly developed website, www.ontariograpeandwineresearch.com


HARVESTING INNOVATION FOR GROWTH AND SUSTAINABILITY

Prepared by: CCOVI, Brock University

Creating innovative support programs, applied practices and outreach services to the Canadian grape and wine industry has been possible with the funding received through Growing Forward’s Developing Innovative Agri-Products (DIAP) program at Agriculture and Agri-Food Canada.

Brock University’s Cool Climate Oenology and Viticulture Institute (CCOVI) has worked collaboratively with the project’s lead the Grape Growers of Ontario (GGO) to address industry-led research priorities with this funding.

Three key activities were identified to address these priorities and the impact of this work on the wine and grape value-chain is already evident. Outlined below are the activities successes.


RAINFAST CHARACTERISTICS OF INSECTIDES

By John Wise, MSU Trevor Nichols Research Complex and Entomology

The numerous rainfall events experienced in Michigan over the last several weeks has prompted many questions about the relative “rainfastness” of the insecticides used in fruit production.  In 2006, the Michigan Agricultural Experiment Station provided funds to purchase and install a state-of-the-art rainfall simulation chamber at the MSU Trevor Nichols Research Complex (TRNC), after which we have begun conducting trials (generously funded by Michigan fruit commodity groups) on fruit crops for a range of insecticides.


WHAT DOES DEACCLIMATION MEAN TO ME?

Prepared by: Dr. Kevin Ker, P.Ag. and Ryan Brewster

Deacclimation occurs as the vines prepare to leave cold winter temperatures and begin to resume active growth as daylight periods lengthen and termperatures rise in the spring. For more information follow the link below.


STRATEGIES TO RECOVER FROM WINTER DAMAGE

Prepared by: Dr. Kevin Ker, P.Ag. and Ryan Brewster

Knowing that winter injury has occurred and where it has occurred in the vineyard is half of the process of dealing with winter injury. the second half involves what strategies to use depending on severity of injury, whether the vines can be easily renewed by retrunking or complete block removal is the best choice.


MAKING DECISIONS AFTER WINTER DAMAGE

Prepared by: Dr. Kevin Ker, P.Ag. and Ryan Brewster

Before pruning injured blocks or replanting some hard decisions need to be made and reviewed


DEALING WITH COLD INJURY

Prepared by: Dr. Kevin Ker, P.Ag. and Ryan Brewster

It is important to recognize bud injury at your vineyard and that damage levels will differ with cultivar and location in the vineyard at your location. Your neighbour with similar cultivars may not have the same damage levels.


SUMMARY OF RECENT MALB RESEARCH FINDINGS FROM THE COOL CLIMATE OENOLOGY AND VITICULTURE INSTITUTE, BROCK UNIVERSITY

A group of research papers that summarize research concerned with the Multi-Colored Asian Ladybeetle (MALB) and ladybug taint in wine.


ESTABLISHMENT AND PRODUCTION COSTS FOR GRAPES IN ONTARIO – 2009 ECONOMIC REPORT

By: Ken Slingerland - Tender Fruit & Grape Specialist/OMAFRA;
      John Molenhuis - Business Analysis & Cost of Production Lead/OMAFRA

This report studies the establishment and production costs of four grape cultivars: Concord, Vidal, Chardonnay and Cabernet Franc.
