Abstract

Recently, severe dieback of apple tree has occurred in the apple orchards of Chungbuk province. Dieback rate and its casual agents have been investigated on the Chungbuk province apple orchards in 2013-2015. Out of 29,265 apple trees in the 27 orchards throughout Chungbuk province, 4,000 apple trees (13.7%) showed dieback symptoms. The causes of dieback were Phytophthora rot (50.4%), violet root rot by Helicobasidium sp. (27.1%), rodents (10%), white root rot by Rosellinia sp. (6.3%), and freezing injury (6.3%). Compared to previous reports published in 1995 and 2006, Phytophthora rot was the most dominant disease, which is thought to be due to high temperature during growing season and the increase of lowland cultivation. Results of this study will be useful to establish of the management strategy of apple tree dieback that has been increased recently.

최근 충북지방의 사과과원에서 사과나무 고사가 심각한 피해를 주고 있다. 본 연구는 2013-2015년까지 충북지방 사과과원에서 발생한 사과나무의 고사율 및 고사 원인별로 조사하였다. 충북 9개 시 군 27개 사과과원에서 조사한 29,265주 중에서 13.7%인 4,000주가 고사하였다. 고사 원인별로는 전체 고사의 50.4%는 역병에 의해, 27.1%는 자주날개무늬병, 10%는 설치류, 그리고 6.3%는 각각 흰날개무늬병과 동해에 의해 발생했다. 1995년과 2006년에 보고된 결과와 비교했을 때 최근에 역병의 발생이 크게 증가한 것으로 나타났다. 그 이유는 재배기간 동안의 고온과 논을 이용한 재배면적의 증가 때문으로 생각한다. 충북지방의 지역별로 고사율과 고사 원인이 달랐다. 본 연구결과는 최근 심각한 피해를 주는 사과나무 고사에 대한 대책을 수립하는데 기초자료로 활용될 것이다.
