A newly identified disease, the Pinot Gris Grapevine Virus, has been detected in a number of vineyards in Napa Valley, but it’s not know what impact it will have on grape yield or quality.

The symptoms of the virus are chlorotic mottling (lacking green chlorophyll), leaf deformation and stunting.

The virus was first observed in 2003 in northeast Italy and identified in 2012, but it has since been found all over the Mediterranean, in Korea, Canada and the U.S.

Napa County viticulture adviser Monica Cooper presented details on the virus at the second session, on pests and diseases, in the Napa Valley Grapegrowers’ Sustainable Vineyard Series last Wednesday. She stood in for author Maher Al Rwahnih of the Foundation Plant Services at UC Davis, who couldn’t attend.

The seminar was held in the auditorium of Copia in Napa, the first return of the sessions to the long-closed facility since its acquisition by the Culinary Institute of America.
