Fabio Quaglino, an international researcher of grapevine phytoplasma diseases, a famous Italian phytoplasmologist and professor at the University of Milan, visited the Scientific-Research Center of Agriculture

The purpose of the visit was to deepen joint research between Georgian and Italian scientists towards the introduction of modern methods for the timely detection, prevention and control of grapevine phytoplasma diseases.
During the visit, Professor Quaglino, together with a group of scientists from the Scientific- Research Center, visited the collection and mother vineyards of the Jighaura Scientific Base and the Kakheti region, examined the symptoms caused by phytoplasma infection on site and collected samples of both Georgian and foreign grape varieties for further laboratory research.
The collected material will be studied in collaboration between Georgian and Italian scientists, both at the immunoenzymatic and molecular laboratories of the Scientific-Research Center and at the University of Milan. Two different modern polymerase chain reaction methods will be used for analysis — TaqMan® RT-PCR and Nested PCR.
Based on the summary of the results obtained in both laboratories, the study of the genetic diversity of grapevine phytoplasma diseases (GY) will continue through sequencing, which will also be carried out at the University of Milan, within the framework of the planned working visit of the center's employees.
Golden yellowing of the grapevine ( Flavescence dorée ) is a quarantine disease that causes serious yield losses to growers. Its timely detection and implementation of preventive measures are crucial for the production of healthy planting material and limiting the spread of the disease.
Expert Fabio Quaglino's visit was carried out within the framework of a three-year project - "Support of certificate program of planting materials according EPPO standards in Georgia", which is funded by the Shota Rustaveli National Science Foundation (code FR 23–1133).
The project aims to ensure timely detection and prevention of grapevine phytoplasma diseases in Georgia, including ,,Flavescence dorée’’ (FD) and ,,Black Wood’’ (Bois Noir, and to introduce modern technologies based on international experience, which will contribute to the sustainable development of Georgian viticulture.
