  • 2002년 7월 경남 통영시 광도면 석류재배 농가포장에서 열매가 부패되는 이상증상이 발생하였다. 분리된 병원균은 감자한천배지에서 균총의 색깔은 흰색이며 물결모양을 이루면서 왕성하게 자랐고, 배지상에서 분생포자각을 잘 형성하였다. 분생포자는 단세포이며 모양은 방추형이고, 색깔은 갈색 또는 올리브색이다. 크기는 10.3~17.4$\times$2.8~4.0 $\mu\textrm{m}$ 였다. 분생포자 형성 세포는 짧은 원통형이며 무색으로 크기는 12.4~1.4$\times$2.8~3.6 $\mu\textrm{m}$ 였다. 불생포자각의 모양은 구형이며 갈색으로, 각벽은 2~3세포이고, 크기는 124.6~228.4 $\mu\textrm{m}$ 였다. 균사생육 적온은 $25^{\circ}C$였다. 분리된 병원균을 건전한 석류에 유상, 무상접종한 결과 접종 3일 후 감염을 일으켰으며, 병원성이 강하였다. 이상과 같이 이 병원균을 Coniella granati에 의한 석류열매 썩음병으로 명명할 것을 제안한다.

  • Since 1993, a total of 50 problematic plant diseases unrecorded in Korea were surveyed in Gyeongnam province. Totally 34 new host plants to corresponding pathogens investigated in this study were 5 fruit trees, 9 vegetables, 12 ornamental plants, 3 industrial crops, and 5 medicinal plants. Among the newly recorded fruit tree diseases, fruit rot of pomegranate caused by Coniella granati and Rhizopus soft rot of peach caused by Rhizopus nigricans damaged severely showing 65.5% and 82.4% infection rate. Among the vegetable diseases, corynespora leaf spot of pepper caused by Corynespora cassiicola and the crown gall of pepper caused by Agrobacterium tumefaciens, powdery mildew of tomato caused by Oidiopsis taurica were the most severe revealing 47.6%, 84.7%, and 54.5% infection rate in heavily infected fields, respectively. In ornamental plants, collar rot of lily caused by Sclerotium rolfsii, gray mold of primula caused by Botrytis cinerea, soot leaf blight of dendrobium caused by Pseudocercospora dendrobium, sclerotinia rot of obedient plant caused by Sclerotinia sclerotiorum showed 32.7 to 64.8% disease incidence. On three industrial plants such as sword bean, broad bean, and cowpea, eight diseases were firstly found in this study. Among the diseases occurring on broad bean, rust caused by Uromyces viciae-fabae and red spot caused by Botrytis fabae were the major limiting factor for the cultivation of the plant showing over 64% infection rate in fields. In medicinal plants, anthracnose of safflower caused by Collectotrichum acutatum was considered the most severe disease on the plant and followed by collar rot caused by Sclerotium rolfsii.(중략)
