Grapevine Pinot Gris Virus

GPGV is a virus recently detected in grapevines in Australia, due to improved diagnostic capability. It is currently classified as exotic under the Emergency Plant Pest Response Deed (EPPRD). Surveillance for this virus has been underway in South Australia and other states since its initial detection, in order to determine its prevalence.

This virus has been reported in numerous countries in both wine and table grape varieties, and vines may show symptoms or be symptomless. Little is known on the effect of the virus on grapevine growth, yield and fruit quality. For technical information, refer to the factsheet
