A new Phytophthora root disease of alder in Italy
Plant Disease 85 (5), 560-560
Abstract: Italian alder (Alnus cordata) seedlings grown in a nursery in Italy were observed with symptoms of sparse yellowish brown foliage with abnormally small leaves, dark stained necrosis of the bark at the collar level, and reduction of the root system due to the death of the tap root and lateral roots. A Phytophthora cambivora-like fungus was isolated from the diseased plants, but showed morphological differences and P. cambivora isolates previously collected in the same area were more thermophilic. Pathogenicity of the isolates was demonstrated by inoculation and re-isolation.
