Occurrence of phytopathogenic fungi on medicinal, aromatic and nutraceutical plants in mountainous areas of Croatia

Croatian mountains mostly belong to Dinarids mountain range and are abundant with medicinal, aromatical and nutraceutical plants among which some are protected and endemic species. Occurrence of phytopathogenic fungi on these plants in natural ecosystems of mountainous areas of Croatia is not investigated well enough. Phytopathogenic fungi cause various diseases or mycoses that are responsible for various changes in host plant natural populations. In order to determine occurrence of phytopathogenic fungi and disease incidence on medicinal, aromatical and nutraceutical plants, appearance of disease symptoms during four year period (2007-2010) was monitored. Monitoring was conducted in Velebit and Biokovo mountain areas on species from genera: Aconitum, Adenostyles, Allium, Amalanchier, Arctostaphylos, Arnica, Asarum, Berberis, Crataegus, Cyclamen, Digitalis, Fragaria, Gentiana, Glechoma, Helleborus, Hypericum, Juniperus, Paeonia, Plantago, Polygonatum, Potentilla, Primula, Rhamnus, Ribes, Rosa, Rubus, Salix, Sanicula, Sorbus, Vaccinium, Tussilago and Veratrum. Samples of plant parts showing symptoms, evidently or possibly caused by plant pathogenic fungi, were collected and analyzed in mycological laboratory. Identification of fungal plant pathogenic species was performed on the basis of morphological characters of their spore-bearing structures and spores. A relatively great number of plant pathogenic fungal species was determined on monitored plant species. Plant pathogenic fungal species mostly belonged to families Pucciniaceae (rust fungi) and Erysiphaceae (powdery mildews). On most plants, at least one fungal phytopathogenic species was determined, except on plant species from genera Arctostaphylos, Arnica, Paeonia and Digitalis which showed no disease symptoms. The determined mycoses usually did not appear with high disease incidence and disease severity, except on several plant species. These exceptions were appearance of disease with high intensity on Veratrum alba caused by rust fungus Puccinia veratri, on Vaccinium myrtillus by fungus Septoria albopunctata and on Helleborus spp. by fungus Coniothyrium hellebori.
