Burgenland orders growers to uproot infected vines after insecticide window closes

Vine growers in Burgenland are being told to remove infected grapevines now that the main period for effective insecticide use has passed, as Austrian officials try to slow the spread of flavescence dorée, a serious grapevine disease carried by the American grapevine leafhopper.

The Burgenland state government said the insect that spreads the disease has been advancing quickly across the eastern Austrian wine region. Officials had already moved against the pest in May through a regulation aimed at controlling its spread. But by August, the leafhopper has reached its adult stage, and insecticide treatments are no longer considered useful in the current growing season because plant protection products work only during the insect’s larval stage.

That shift has pushed the response into a new phase centered on identifying and uprooting diseased vines. Officials said this is the moment when symptoms are especially visible, making it easier for growers and residents with vines to spot possible infections in vineyards and private plots.

According to the state, white grape varieties typically show yellowing leaves, while red varieties develop dark red discoloration. As the disease progresses, the leaves curl downward. The infection can severely damage vines and render them unproductive.

“We can still fight the disease effectively,” Deputy Governor Anja Haider-Wallner said in a statement issued by the state. She urged winegrowers and the public to inspect vines carefully and remove infected plants quickly on their own responsibility. “Every vine that is uprooted takes away part of the basis for the further spread of flavescence dorée,” she said.

The state’s official plant protection service has defined 77 infestation zones in Burgenland this season based on leaf samples. The only district without a confirmed case so far is Mattersburg, although 39 samples there were still awaiting analysis by the Austrian Agency for Health and Food Safety, known as AGES.

The spread has affected some of Burgenland’s best-known wine areas. Officials said the Eisenberg wine region in the districts of Güssing and Oberwart, the Blaufränkischland area around Deutschkreutz, Horitschon, Lutzmannsburg and Neckenmarkt, the Leithaberg wine region from Müllendorf to Jois, and the western side of Lake Neusiedl around Rust have been designated almost entirely as security zones.

In the Seewinkel area, the winegrowing communities of Gols, Podersdorf and Pamhagen are among those particularly affected. The designations reflect where officials believe tighter monitoring and control are needed as the disease pressure grows.

The campaign matters far beyond a single harvest. Burgenland is one of Austria’s leading wine regions, known for both red and white wines, and the spread of a vine disease that can destroy productivity has raised concern across the sector. The state’s current message is that once the insect can no longer be effectively targeted with sprays, the fastest way to reduce risk is to remove the infected host plants before the disease can move further through vineyards and surrounding vine plantings.
