Farming Sector - Rainfall issues for vineyard owners: Fungi pose a threat to crop health
Excessive rainfall has been an issue for winemakers in the southwest, with pest control concerns arising due to potential long-term fungal diseases such as false mildew. The Managing Director of the Baden Winegrowers Association, Holger Klein, expressed his concerns, stating, "The constant moisture is not ideal."
Peter Albrecht, the Vice President of the Winegrowers Association of Württemberg, shared similar sentiments about the potential threat of false mildew, warning that "this could become a problem if the weather continues like this." However, an immediate danger to the Württemberg region is not yet present.
Both false and true mildew, along with gray mold, are regarded as the leading pests of vineyards. Traditional winegrowing methods involve frequent spraying of plants with protective agents to maintain grape health. New "Piwi" grape varieties, with increased disease resistance, require less of these treatments.
Stefan Huschle, of the Freiherr von und zu Franckenstein winery in Offenburg, believes that the rainfall actually benefits the industry. He explains, "There are now sufficient groundwater reserves again." Frost damage has occurred in vineyards within the regions of Ortenau and others, though the consequences are highly variable and challenging to evaluate.
In the past, the Winegrowers Association of Württemberg estimated that up to 50% of their vineyards have been affected by frost incidents. These frosts occurred most recently at the end of April, following a period of relatively warm temperatures that led to premature budding across many areas.
Baden and Württemberg are the third and fourth largest winegrowing regions in Germany, respectively, surpassed only by Rheinhessen and Palatinate.
