Napa,CA -- The International Technical Working Group for the European Grape Vine Moth (EGVM) in California issued its second and final report after meeting in Napa recently. It includes specific recommendations for controlling the invasive pest in Napa County, but the recommendations apply to the other seven infested counties in California, too. Control will involve considerable effort by growers and wineries and grape transportation companies. The working group identified the EGVM as the cause of severe damage late last summer in several vineyards in Napa County, where the insects and associated Botrytis infections caused complete loss of harvest from two vineyards and unacceptable tainting of wine made from grapes of another vineyard.
