Septoria Leaf-Spot Disease in Lavender Detected for First Time in Switzerland
Following the first confirmed detection of Septoria leaf-spot disease in Switzerland, Agroscope has published an information sheet to explain the symptoms on lavandin (hybrid lavender) and true lavender and to highlight control options.
In September 2024, an essential-oil producer in the Jura contacted Agroscope‘s ‘Medicinal and Aromatic Plants‘ Group about leaf spots on an organic lavandin crop. Based on photos and samples of diseased plants received as well as a description of the damage, the diagnosis was steered towards Septoria leaf-spot disease of lavender. Microscopic examination of the fungal spores confirmed this diagnosis, since both their size and morphology exactly matched those of the pathogen Septoria lavandula.

Berries and Medicinal Plants
The work of the ‘Berries and Medicinal Plants’ Research Group aims to ensure the sustainable production of berries and medicinal plants based on efficient methods of production, plant protection and post-harvest processes, which, in particular, increase product quality, improve competitiveness and minimise risks for the environment. Innovative production systems such as vertical farming and agrophotovoltaics are put to the test.
