Outbreak and Spread of Bacterial Canker in Kiwifruit

참다래 궤양병의 격발 및 확산

Bacterial canker of kiwifruit recently outbroke throughout the southcoast of Korea, the major production areas of kiwifruit. Some orchards were destroyed because of severe damage by the epidemics of the bacterial canker, especially in Jeju-si and Bukjeju-kun, Jeju and Goheung-kun and Wando-kun, Chonnam. The bacterial canker, which has been occurred in Jeju from the mid 1980s, was first observed in Haenam-kun, Chonnam in 1991. The disease outbroken throughout the southcoast of Korea caused extremely severe damages and the diseased areas are increasing continuously. The possibility that the bacterial canker was introduced from Japan into Jeju is high, although the path of the epidemic is still not clear. And then the bacterial canker may spread from Jeju to Haenam and/or Wando, from which the disease may spread to the southcoast of Chonnam and the westcoast of Kyungnam in Korea.
