| Abstract: | Dothistroma Needle Blight (DNB) has been known in Slovenia since 1971, but the disease symptoms have intensified in recent years. With this study, the DNB symptoms in Slovenia are for the first time connected to both phytopathogenic Dothistroma species: D. pini and D. septosporum. Based on the ITS‐rDNA comparisons, the Slovenian isolates of D. pini group with the D. pini isolates from France, Hungary and the USA and not with the D. pini isolates from Russia and Ukraine. Both mating types MAT1 and MAT2 of D. septosporum are present in Slovenia, while for D. pini, only MAT2 was found. The current widespread occurrence of D. pini in native forest stands indicates the prolonged presence of this species in Slovenia. |
