This study was conducted in the years 1995-2005. Melampsora pinitorqua which is fairly widespread in Turkey was first determined on Pinus sylvestris in plantation areas of Karabük-Dikmen in 1995. The case area was investigated during certain periods each year between 1995 and 2000. The disease reached the highest level during 1955-2000. After 2000, the damage has started to decrease and the impact of fungus completely vanished in 2005. Disease severity was high in 2000 because Pinus sylvestris was in 1-10 years old and Aspen (Populus tremula) which is uredial and telial host of the fungus was very dense in this area and Pinus sylvestris was not a native tree for the area. After 2004, the disease has completely dissappered since Pinus sylvestris overcame the suscepitible age of 1-10 years old to disease and Populus tremula was destroyed in the area.
