Abstract

This study was carried out to provide pest control information for the cultivation of Eleutherococcus senticosus Max. As a result of investigation of the diseases and insect pests, three pathogens and three insect pests were identified from the field sample, respectively. The identified insects pests were aphids, stinkbugs and Bothrogonia japonica. Occurrenre peaks of aphids were occurred on June and August, and generally young leaves and flower buds were injured mainly. The identified diseases were black ring spot caused by Phoma sp., gray mold caused by Botrytis cinerea and leaf blights caused by Rhizoctonia solani. The black ring spot was the most severe disease and was investigated from the beginning of June, and the incidence of the disease was 30% higher than that on September. As a result of growth test under different temperature conditions on PDA, these pathogens showed the best mycelial growth rate between 25 $^{\circ}$C and 30 $^{\circ}$C, and these results indicate that these diseases occur on hat summer season.

가시오갈피에 발생하는 다양한 병해충을 분리, 동정하여 가시오갈피의 지속적인 안전재배를 위한 병 ${\cdot}$ 해충방제의 기초자료로 활용하고자 시험을 수행하였다. 가시오갈피에 발병하는 병원균을 분리동정한 결과 Phoma sp., Rhizoctonia solani, Botrytis cinerea 등 3종으로 밝혀졌으며, 병징의 특징에 따라 각각 검은무늬병, 잎마름병, 잿빛곰팡이병으로 명명하였다. 병원균에 의한 가시오갈피의 피해는 Phoma sp.에 의한 검은무늬병이 가장 컸으며, 개체별 병징의 형태나 병발생의 차이는 있었지만 6월 초부터 병반이 관찰되어 9월부터 병반면적이 30%를 넘어 계속 확대되었다. 수집균주의 배양온도별 균사생장량을 검토한 결과 균주 모두 $25^{\circ}C{\sim}30^{\circ}C$에서 생장량이 가장 많아, 여름 고온기에 많이 발생할 것으로 사료되었다. 해충별 발생시기 및 가해부위를 보면 진딧물은 6월 10일부터 관찰되어 어린 줄기를 흡즙하였고, 8월 상순에 다시 발생해 새로 분화되는 어린 화아에 집중적으로 발생하여 흡즙하였으며 노린재와 끝검은말매미충은 8월하, 6-7월에 각각 나타났으나 피해는 관찰되지 않았다.
