The aim of our research is to elaborate the methods of early detection of plant pathogenic fungi in the air and in host-plant tissues to identify these species and help to develop strategies of crop protection. Since 2004 the Team has been managing the Decision Support System for Forecasting Disease Epidemics SPEC ( - the world's third biggest system based on aerobiological monitoring of the primary inoculum of plant pathogens of crop plants. Research concerns also mycological and molecular characterisation of pathogens aiming at the recognition of the structure and changes in fungal populations, what  allows to determine proper strategies of resistance breeding.   We search for sources of genetic resistance of plants to pathogens. Etiological and epidemiological studies are mainly focused on pathogens originating from the kingdom of fungi (Fungi), including necrotrophs (mainly of the genera: Alternaria, Fusarium, Leptosphaeria, Ramularia and Sclerotinia), and biotrophs (Melampsora). At present the studies also concern Plasmodiophora brassicae - the representative of the kingdom of protists (Protista).
