Is Grapevine Pinot Gris Virus in South Africa?

by | Apr 30, 2020 | South Africa Wine Scan

Researcher: Prof Gerhard Pietersen, Department of Genetics, Stellenbosch University

Aim and industry relevance:
The purpose of this project is to determine whether Grapevine Pinot Gris Virus occurs in the field in grapevines in South Africa. Grapevine Pinot Gris Virus is a newly discovered and apparently widespread, emerging virus internationally. The virus is transmitted by an eriophyid mite that is found in South Africa. The virus has not been reported from South Africa, but also has not been tested for here. If found in field material, researchers wish to determine whether it is already widespread and will develop a reliable diagnostic protocol to detect and identify the virus for local use.
