Sažetak
Indigenous and allochthonous pine species in Croatia are of a great silvicultural value and provide numerous commercial and non-commercial benefits. As the pioneer tree species with the ability to colonise degraded sites and improve properties and biological activity of soil, Austrian pine (Pinus nigra J.F.Arnold) and Aleppo pine (Pinus halepensis Mill.) are the most frequently used species for the afforestation of the Mediterranean karst area in Croatia. Their very important and distinctive anti-erosion and hydrological role have also been proven in various studies conducted in the area of Croatian karst and wider. Besides the afore-mentioned benefits, pine species are often seen as the ornamentals in parks, private yards and urban areas in general, where they have several social functions related to aesthetics, health, recreation and tourism. Pines in Croatia are the preferred hosts to a certain number of parasitic fungi, including the species from the genus Dothistroma Hulbary 1941, causative agents of red band needle blight, known also as Dothistroma needle blight. The disease has been reported to have great effects and tendency of spreading on pines and other conifers throughout Europe, causing premature needle defoliation, lower timber yield and eventually tree mortality. In Croatia it has been first reported in 1963. on Austrian pine in the vicinity of Slavonski Brod, from where it has spread to other continental areas and was discovered on several other species (Pinus mugo Turra, Pinus ponderosa Douglas ex C.Lawson, P. strobus L. and P. densiflora Siebold & Zucc.), but in limited distribution. Although the disease can be lethal to the Austrian pine seedlings in nurseries and young trees in forest plantations and urban areas, where it can cause severe economical and ecological damage, only several studies have been conducted on these fungi in Croatia up-to- day. Aim of this research was to study the occurrence of Dothistroma needle blight on two locations, one maritime (Istria) and one continental (Đurđevački Peski) in two different periods of the year (spring and autumn) in order to gain more insight into the biology and current spread of these pathogens, which will provide valuable information for the future protective measures of pine species in Croatia.
