EPPO Reporting Service 512/06. Doubtful record.

EPPO Reporting Service (1998/204) : a new Erwinia described from Pyrus pyrifolia. Closely related to, but distinct from, E. amylovora. Named E. pyrifoliae. Earlier doubtful records could refer to this.

EPPO Reporting Service (2015/089) : first found in May 2015 in 3 adjacent pear orchards in the cities of Anseong and Cheonan, under eradication.

EPPO Reporting Service (2016/162) : also found in June/July 2015 in 2 commercial apple orchards in the cities of Anseong and Jecheon.

In 2015, E. amylovora was detected in 1,092 trees (768 pear trees, 324 apple trees) in 46 orchards in the southern part of Han river. Eradication continues (all infected orchards have been destroyed).

EPPO Reporting Service (2017/053) : observed in July 2015 on Chinese quince (Chaenomeles sinensis) in a nursery in Cheonan. Eradication continues.

EPPO Reporting Service (2017/206) : in August 2017, the bacterium was confirmed by molecular techniques in 18 pear orchards and 4 apple orchards. These orchards are located within an area of 16 km diameter in Anseong and Cheonan. Eradication continues.

EPPO Reporting Service (2019/149) : fireblight was found in 17 pear and 99 apple orchards in Anseong and Cheonan, as well as in 2 pear and 49 apple orchards in Jecheon. New outbreaks (6 apple orchards) were found in Eumseong. Eradication continues.

From NPPO (2020): official surveys detected E. amylovora in 462 pear and apple orchards [Chungju (300 orchards), Jecheon (105), Eumseong (10), Jincheon (2), Anseong (26), Paju (2), Icheon (2), Yeoncheon (2), Pyeongchang (2), Cheonan (6), Iksan (2), Yangju (1), Gwangju (Gyeonggi province) (2)]. Most infected orchards (98%) are located within 50 km radius.

From Jik Lee et al. (2022): in 2020, 744 orchards were found infected. The main pathways for disease spread are considered to be movements of infected planting material and use of contaminated pruning tools.
