$163 billion grape industry at risk due to spread of grapevine red blotch virus with no known treatment
$3 million grant given to institutions in California and Oregon to address unknowns of disease and mitigate its effects on grape production, wine quality. Less than an hour from UC Davis, lie the towns of Napa and Sonoma, both hubs of the $163 billion US grape industry. California-grown grapes makes up 90% of the country’s wine production, yet they are at risk as a currently untreatable grapevine disease spreads rapidly across the country but especially in California and Oregon vineyards.
Ancient, heat-hardy wine grapes are being resurrected in Spain to deal with rising temperatures. Worried producers in Bordeaux—where Cabernet and Merlot have long ruled—have approved the use of seven new wine grapes from Portugal, Spain and southern France in their blends. The University of California at Davis recently released five new hybrid grape varieties—its first such release since the 1980s—to resist vine-killing insects expected to proliferate as winters warm.
The United Nations General Assembly declared 2020 as the International Year of Plant Health (IYPH). The year is a once in a lifetime opportunity to raise global awareness on how protecting plant health can help end hunger, reduce poverty, protect the environment, and boost economic development.
Ontario Grape and Wine Research Incorporated invite research proposals for the Research and Innovation Development Initiative (R&ID) component for the Marketing Vineyard Improvement Program (MVIP). The objective of this program is to provide funds to improve the quality, productivity and adaptability of grape and wine production by promoting industry-wide access to innovative tools, technologies, resources, knowledge and information for grape and wine making.
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 ...
