Horse chestnut (Aesculus hippocastanum L.) is an endemic species of the south part of Balkan Peninsula, which grows naturally only in the basin of the river Drina. Owing to its ecological characteristics and decorative quality, it is frequently used as a park tree and for formation of tree lines. As a result of increased exposure to harmful actors in urban environment, it weakens physiologically and becomes predisposed to attacks of harmful organisms. This paper presents the results of a two-year study of diseases that occur in all development phases of the horse chestnut. Furthermore, the paper presents for the first time a study of species of genus Phytophthora in horse chestnut in Serbia. The most commonly identified fungus in assimilation organs is Guignardia aesculi, which causes an occurrence of leaf spots. The most substantial harm on adult trees is caused by decay causing fungi. Among all identified decay causing fungi, the most harm is caused by Inonotus hispidus, Ganoderma adspersum and Ganoderma applanatum.
