Abstract

Since 2007, an increased incidence of disease symptoms had been observed in the chamomile stocks in Thuringia, the cause of which was unclear. In addition to animal pathogens, various fungal pathogens, primarily Septoria sp. and an unknown fungus (UBK), had been found on chamomile stocks in Thuringia as well as pathogens such as Golovinomyces cichoracearum var. cichoracearum (powdery mildew), Paraperonospora leptosperma (powdery mildew), Puccinia matricariae (rust) and Colletotrichum sp. The importance of the unknown fungus for the damage level of chamomile was unclear. References from the literature were not available.
In molecular biological studies, the Septoria species was clearly identified as Septoria matricariae. The unknown fungus UBK is assigned to the division of the ascomycetes with the order helotiales.
