Abstract: 2003–2011 m. Vilniaus universiteto Botanikos sode buvo tiriama 42 genčių žolinių dekoratyvinių augalų fitosanitarinė būklė. Nustatyta 41 grybų rūšis, priklausanti 21 genčiai. Plačiausiai paplitę yra Alternaria, Erysiphe ir Botrytis genčių grybai. Labiausiai pažeidžiami – Aster dumosus, Dahlia pinnata, Gladiolus communis, Lilium sp. cult., Paeonia perigrina, Primula veris, Tulipa gesneriana augalai.
During 2003-2011 in the Botanical Garden of Vilnius University phytosanitary condition of 42 genera herbaceous ornamental plants was studied. The plant disease agents were identified employing the following methods: moist chamber, isolation of pure cultures for identification of plant disease agents, microscopy. The 41 fungal species belonging to 21 genera have been identified. The prevalent fungal genera were: Alternaria, Botrytis, Erysiphe. The plants genera Aster, Gladiolus, Dahlia,Lilium, Paeonia, Primula, Tulipa are beeing infected every year. Phytosanitary condition of plants depends on many factors, especially on meteorological conditions. Every species of fungi reacts differently to climatic conditions. In summer, when the air was particularly dry and hot, the fungal pathogens did not spread, and fungal diseases appeared only in autumn. In the first part of summer, when the air temperature was low, the causal agents of plant rot were prevalent.
