Viruses are of great concern in vineyards. They cost the California wine grape industry as much as $91,661 per acre over the life of a vineyard, according to a 2015 economic study of the North Coast wine-growing region. As a first step towards managing viruses, growers are encouraged to plant certified material regulated by the California Registration and Certification program. There are risks in sourcing material from stocks that are not subject to the same level of regulation. We surveyed ...

LangeTwins Family Winery & Vineyards in Lodi has implemented a vineyard virus scouting, mapping and vine rogueing program aimed at managing leafroll and red blotch virus infections and preventing their spread. The program, used in newer plantings of red winegrape varieties (planted since about 2013) is modeled after a successful program used in South Africa where vine mealybug (Planococcus ficus) and leafroll viruses have been ongoing management issues in winegrape vineyards.
Bio-security refers to a series of management practices designed to prevent, minimize and manage the introduction and spread of pests. This includes pests not established in Canada, pests established in limited areas of Canada, and pests widely distributed that can spread from farm to farm.
The Grape Growers of Ontario, in partnership with Brock University's Cool Climate Oenology and Viticulture Institute (CCOVI) are pleased to announce the launch of a brand-new viticulture webinar series. The series will look at current topics with experts in the field from bud survival to irrigation timing.
This comprehensive 114-page guide, available as a free download in English and French, was created in a field-sized format to help growers identify the pests in their vineyards and make informed decisions about how to best protect their grapes. Better understanding the numerous beneficial insects present in the vineyard will enable them to produce grapes sustainably and reduce their reliance on chemical interventions.
