Grapevine Pinot Gris Virus (GPGV) has recently been detected in Australia. It was formerly identified overseas in 2012, although it may have been present for about 10 years.
GPGV has been found on more than 30 grape varieties worldwide, and was first detected on Pinot Gris.
Symptoms of GPGV appear soon after bud break. Symptoms consist of shortened internodes, leaf mottling, yellow spots, leaf deformation, delayed bud burst, mite attack and poor fruit set. GPGV, however, can be symptomless making it impossible to identify by visual symptoms.
GPGV is spread by grapevine bud and blister mites and propagating material. Weeds such as fat hen (Chenopodium album) and white campion (Silene latifolia) can harbour the disease and act as reservoirs for the virus.
If you suspect you have GPGV infested vines you must report it to Agriculture Victoria by calling the Exotic Plant Pest Hotline 1800 084 881 or emailing email@example.com
Samples for testing can be sent to Crop Health Services, AgriBio Bundoora. You can contact Agriculture Victoria’s Crop Health Services team on T: 03 9032 7323 for a quote on testing and information on collecting, packaging and sending samples for analysis.
It is important to maintain good biosecurity on-farm to prevent spread of GPGV. You can do this by controlling weeds and insect pests, inspecting vines, using certified propagation material, and reminding visitors of good on-farm hygiene.
