Grapevine Pinot Gris Virus detection

Grapevine Pinot Gris Virus (GPGV) was recently detected in Australia and has been reported in many international wine regions in Europe, the US, Canada and China. As well as Pinot Gris, it can infect a number of other wine and table grape varieties, including Pinot Noir, Traminer, Chardonnay, Merlot, Cabernet Franc, Cabernet Sauvignon and Shiraz.
The effect of GPGV on vine health is difficult to determine, as the virus is often found in infections with a mix of other viruses. However, it has been associated with economic losses, particularly in the presence of other viruses.
