  • Ginseng anthracnose was observed in Koyang area, Korea. A fungus was repeatedly isolated from leaves and stems of the infected ginseng plants and identified as Colletotrichum dematium according to the morpho-logical and cultural characteristics. The fungus showed pathogenicity on inoculated ginseng leaves. This is the first report of ginseng anthracnose caused by Colletotri-chum dematium in Korea.

  • Serve outbreaks of anthracnose were observed on perilla plants grown in greenhouses and open fields in several locations in Korea during the disease survey from 1997 to 2000. A total of 53 isolates of Colletotrichum spp. and Glomerella sp. was obtained from diseased perilla plants and identified based on their morphological and cultural characteristics. Forty isolates were identified as Colletotrichum gloeosporioides, three isolates as C. coccodes, five isolates as C. dematium, and the other five isolates as Glomerella cingulata, the teleomorph of C. gloeosporioides. All isolates of C. gloeosporioides tested by artificial inoculation were strongly virulent on perilla plants, but isolates of the other species were weakly or not virulent. Anthracnose symptoms induced on the perilla plants by artificial inoculation with the isolates of C. gloeosporioides were similar to those observed in the fields. This study revealed that C. gloeosporioides is the main causal fungus of perilla anthracnose.

  • 고추 역병과 탄저병은 Phytophthora capsici와 Colletotrichum gloeosporioides에 의해 발병되는 병으로 세계적으로 많은 피해를 입히는 중요한 병원균이다. 이러한 병원균의 방제를 위하여 근권과 비근권에서 각각의 병원균 생장을 억제하는 능력이 뛰어난 5균주를 선발하였다. 선발된 분리주 중 S54균주는 in vitro와 in vivo 조건 모두에서 가장뛰어나게 병원균을 억제하였다. 하우스 실험에서도 역병과 탄저병 모두 80% 이상의 방제력을 보여주었다. 또한 S54균주의 동정을 위하여 16S rDNA 부분의 염기서열의 분석과 API 50CHB Kit를 실시하였으며, 그 결과 Bacillus subtilis로 동정하였다. 이러한 결과를 바탕으로 S54는 고추 역병과 탄저병을 방제할 수 있는 생물학적 방제제로의 가능성을 보여주었다고 할 수 있다.
