Species-specific primers for Eutypella parasitica, the causal agent of Eutypella canker of maple.

A quick molecular method to diagnose a newly reported pathogenic fungus Eutypella parasitica in Europe was developed for the first time. 68 isolates of Eutypella parasitica, the causal agent of Eutypella canker of maple, were evaluated with RFLP and sequencing of ITS-rDNA region. Species-specific primers were constructed and we successfully detected the fungus E. parasitica in the infected plant material. The developed technique enables quick detection of this fungus in diseased material and is additionally important as a confirmation method to morphological identification.

Chalara fraxinea causing common ash dieback newly reported in Slovenia.

On the territory of Slovenia new disease of ash, which is caused by the fungus Chalara fraxinea, was reported for the first time. The fungus was isolated into the pure culture and morphologically characterized by growth characteristics and microscopic characters. Koch's postulates were performed and the pathogenicity of the fungus was proved.

First report of Erysiphe arcuata and new data about three invasive powdery mildews in Slovenia

The current paper is the first report of powdery mildew Erysiphe arcuata on Carpinus betulus in Slovenia. It was found in arboretum Volčji Potok in 2007, afterwards also at numerous other locations througout Slovenia and we conclude that it is widely distributed and frequent. New locations of three powdery mildews, which were introduced into Slovenia previously and are now widely distributed, are reported: Erysiphe azaleae was introduced in 2004, Erysiphe flexuosa in 2003 and Erysiphe elevata in 2003.

The first record of Cinara curvipes (bow-legged fir aphid) in Slovenia and its possible economic impact

The presence of the exotic phytophagous bow-legged fir aphid, Cinara curvipes, was detected for the first time in Slovenia. The presence of the aphid on Abies alba confirms the capacity of the aphid for host switching which could lead to its spreading in silver fir forests (Abies alba). An overview of the relevant literature on the taxonomy, biology, and economical importance of C. curvipes is provided.
