First report of Alternaria mali in Iran
In Iran, the main apple-growing areas are located in the north of the provinces of East Azarbaijan and West Azarbaijan. During a survey on apple diseases done in 2006, foliar symptoms were observed in several parts of these provinces. Dark necrotic spots surrounded by chlorotic areas were observed on apple leaves. Spots reached 0.7 to 3 cm and appeared mainly on older leaves of the cultivars ‘Red Delicious’ and ‘Golden Delicious’. Morphological characteristics and pathogenicity tests revealed the presence of Alternaria mali (EU Annexes). This is the first report of A. mali in Iran.
The situation of Alternaria mali in Iran can be described as follows: Present, first found in 2006, in the north of the provinces of East Azarbaijan and West Azarbaijan.
