Abstract

Tujerodna gliva Lecanosticta acicola, ki povzroča bolezen imenovano rjavenje borovih iglic, je bila v Sloveniji prvič najdena leta 2008. Prve okužbe so bile najdene v urbanem okolju, leta 2014 pa je bila prvič najdena tudi v naravnem okolju, in sicer ob reki Soči v Trenti. Okuženi osebki rušja (Pinus mugo) so bili takrat posekani in uničeni. V naši raziskavi smo ugotavljali, če je patogen kljub takrat izvedenim ukrepom v Trenti še vedno prisoten. Prav tako smo poskušali ugotoviti, če se bolezen iz območja Zgornje Soške doline, kjer se je razširila v zadnjih letih, širi tudi proti osrednji Sloveniji. V začetku junija 2021 smo zato v Trenti in na relaciji Most na Soči - Podbrdo - Škofja Loka vzorčili osebke bora (Pinus spp.) s sumom na okužbo z glivo L. acicola. Odvzeli smo 29 vzorcev, okužbo pa potrdili v dveh vzorcih rušja (Pinus mugo) iz Trente ter v vzorcih rušja (Pinus mugo) in rdečega bora (Pinus sylvestris), ki sta bila odvzeta v Kneži. V 15 vzorcih smo potrdili okužbo z glivo iz rodu Dothistroma, ki povzroča rdečo pegavost borovih iglic. Z našo raziskavo smo tako ugotovili, da ukrepi izvedeni konec leta 2014 niso bili zadostni za izkoreninjenje patogena v Trenti. Kraj Kneža sicer predstavlja novo žarišče bolezni, vendar pa z našo raziskavo bistvenega širjenja bolezni nismo potrdili.

Secondary title:	Distribution of the fungus Lecanosticta acicola in Trenta and its spread towards central Slovenia
Secondary abstract:	The non-native fungus Lecanosticta acicola, that causes a brown spot needle blight, was first found in Slovenia in 2008. The first infections were found in the urban environment, and in 2014 the pathogen was also found for the first time in the natural environment, along the Soča River in Trenta. Infected specimens of Pinus mugo were cut down and destroyed. In our diploma thesis, we tried to find out whether the pathogen is still present in Trenta, despite the measures taken at the time. We also tried to find out if the disease is spreading from the area of the Upper Soča Valley, where it has established in recent years, towards central Slovenia. At the beginning of June 2021, we sampled pine trees (Pinus spp.) with a suspicion of infection with the fungus L. acicola in Trenta and along the route Most na Soči - Podbrdo - Škofja Loka. We took 29 samples and confirmed the infection in two samples of Pinus mugo from Trenta and in samples of Pinus mugo and Pinus sylvestris, which were taken in Kneža. In 15 samples, we confirmed infection with a fungus of the genus Dothistroma, which causes a red bend needle blight. With our research, we thus found that the measures taken at the end of 2014 were not sufficient to eradicate the pathogen in Trenta. Location Kneža represents a new infected area, but we have not confirmed the significant spread of the disease.
