Records of Brown spot needle blight related to Lecanosticta acicola in the Czech Republic

There are two records of brown spot needle blight caused by Lecanosticta acicola in the Czech Republic up to date. This disease was first reported on June 2007 in National Nature Reserve (NNR) Cervena Blata, South Bohemia. A more recent discovery of L. acicola took place on August 2008 in the NNR Borkovicka Blata. The disease was observed on 10-60 year old Pinus rotundata. Both locations with infected trees are situated inside nature conservation sites under strict protection regimes that are located approximately 50 km apart. In both sites, L. acicola occurred simultaneously with Dothistroma septospora, the red band needle blight causal agent on Pinus sylvestris, P. rotundata and their hybrid (P. x digenea). However, infections of both diseases on the same tree have not yet been observed.
