This diploma thesis deals with fungal pathogen Sphaeropsis sapinea, which extends massively mainly to the Austrian pine (Pinus nigra). Dieback and die of Austrian pine are caused cooperation between stress and Diplodia blight. Thesis summarized the knowledge of the effects and influence of this pathogen on trees, monitors the possibilities of defence and protection, finding a fungicide in the laboratory, which would effectively reduce damage by injection into mature trees, subsequently. Nine commercially available fungicides were tested in laboratory conditions. Topas 100 EC (effective substance penconazole), Propizol 250 EC (effective substance propiconazole), Dithane DG Neotec (effective substance mancozeb) and Horizon 250 EW (effective substance tebuconazole) had impact for limitation of grow of mycelium S. sapinea. Horizon 250 EW (effective substance tebuconazole) has the highest effectivity in laboratory testing. However, the field testing did not prove its very good properties from laboratory testing.
