Some aspects of Sphaeropsis sapinea presence on pines in Croatia and Slovenia

The fungus Sphaeropsis sapinea (Fr.) Dyko et Sutton wide spread in temperate and tropical regions all over the world causes different types of diseases on conifers. In 1992 it turned out as the major cause of Austrian pine dieback in Istria (Croatia). From 1992 and up-to-date pine dieback symptoms have been observed in the North Adriatic area and in the region of Zagreb city. Dieback of shoots, branches, parts of crown and hole pine trees were notified. In Slovenia fungus was isolated as an endophyte from green needles of Austrian pine collected on few localities in 1993-95. Research on different biological aspects of Sphaeropsis sapinea isolates has been done. Inoculation experiment confirmed the fungus pathogenicity and revealed no difference between Croatian and Slovenian isolates.
