Identification of taxa of microscopic fungi occurring on selected herbal plants and possible methods of their elimination

The study was conducted in 2014 at the West Pomeranian University of Technology in Szczecin. Its aim was to identify the taxa of microscopic fungi present on selected herbal plants and to propose methods of their elimination. Research material included leaves and stems of affected plants. The material was collected at the end of the growing season (in September). The study identified 11 taxa belonging to two types of fungi: Ascomycetes and Basidiomycetes. Most identified taxa (98.2%) belonged to Ascomycetes. Three species rarely found in Poland were recognized: Ascochyta levistici, Septoria melissae and Phragmidium sanguisorbae. Diseases of herbal plants should preferably be eliminated by using biological methods and appropriate agrotechnical treatments.
