First report on fruit spot caused by Colletotrichum gloeosporioides in apple (Malus pumila Mill.) in Korea.
From 2013 to 2014, a devastating fruit spot disease was observed in apple orchards in the northern Gyeongbuk Province (Andong, Youngju, Mungyeong, Yecheon and Yeongyang) of Korea Republic. In many orchards, the incidence of this disease in apples was ranged from 2.0 to 5.3. Initially, small lesions (<5 mm2) were observed on fruit nearing maturity, expanded to 5-10 mm2 and then remained static until harvest maturity. The causal pathogen was identified as Glomerella cingulata based on morphological, genetic (ITS) and pathogenicity analyses. This is thought to be the first report of fruit spot caused by G. cingulata on apples in Korea Republic.
