First Report of Phytophthora Citricola on Cornus Mas in Bulgaria [link]Paper  doi  abstract   bibtex   
In the springs of 2007 and 2008, severe, unusual damages were observed on sporadically scattered plantlets of 'Kazanlashki' (known also as 'Kazanlaker') in a nursery located near Vratza in northwestern Bulgaria. Symptoms were identical in both years and expressed on the leaves, young shoots, and adjacent rootstock wood. Dark brown, necrotic leaf spots initiated most often from the leaf periphery and quickly covered more than half of the leaf area. Necrosis of the leaves and shoots spread toward the older woody tissues and the plantlets died within a couple of weeks. Isolations from symptomatic leaves, shoots, and rootstocks (three to five samples per plant organ) on potato dextrose agar always revealed a fungus-like organism that formed relatively fast-growing white, radial, petaloid colonies. The morphological data identified the organism as Phytophthora citricola (1).
