Flavescence dorée disease confirmed in all 22 Hungarian wine regions

The Flavescence dorée (FD) disease, caused by the phytoplasma Candidatus Phytoplasma vitis, has been confirmed in all 22 Hungarian wine regions. The final unaffected area, the Bükk wine region, saw the pathogen identified in mid-August by the National Food Chain Safety Office (Nébih) in samples from Mályi, Miskolc, and Tibolddaróc.

In response, authorities have implemented quarantine measures in Borsod-Abaúj-Zemplén county. This includes a 1 km radius around infected sites where all vines must be inspected and symptomatic plants destroyed. A 3 km buffer zone has also been established for intensive monitoring and mandatory defense programs. The movement of grapevine propagating material from affected areas is strictly prohibited.

The disease, spread by the American leafhopper Scaphoideus titanus, has seen rapid expansion. Experts suggest that total eradication is no longer a realistic goal, shifting the focus toward slowing spread and mitigating damage. In 2025, approximately 300,000 vines required removal, resulting in the loss of 60–85 hectares and significant economic impact. Research programs by HUN-REN institutions are currently working on rapid genetic screening and improved epidemiological modeling to manage the outbreak.
