Abstract

We investigated turfgrass diseases and inoculum density at nationwide turfgrass cultivation sites in year of 2013. Occurrences of large patch and rust disease appeared in September. Brown patch recorded in September to October at Namhea and Pythium blight disease occurred outbreaks in early July at Namhea site. Some sites in Namhea damaged 3% area of total cultivation field by Sclerotinia homoeocarp. In Daepyeong (Gyeongnam), Fairy ring and large patch were recorded. Severe takeall and fairy ring have been observed in Gochang-si. Multi-site in Cheongju-si, brown patch was observed in pandemic level. Interesting enough, a cool-season turfgrass cultivate sites in Pyeongtaek-si brown patch, leaf blast, summer patch, and Curvularia leaf spot were investigated during the surveys period. Inoculum densities (Rhizoctonia spp.) at turfgrass cultivations sites were increased as cumulatively in all survey sites. The investigation result indicated that the disease occurrence and pathogens are similar as diseases in golf courses.

본 연구에서는 2013년 잔디 재배지에서 발생하는 병해와 Rhizoctonia spp. 밀도를 조사하였다. 진주포장에서 갈색퍼짐병(Large patch)이 35% 발생하였고, 9월에 녹병이 발생하였다. 갈색마름병은 남해지역에서 9월과 10월을 거쳐 발생하였으며 7월 초 피시움잎마름병이 대발생 하였고, 동전마름병(Dollar spot)의 경우 전체 면적에 3%에 달하는 면적이 심각하게 피해를 입은 포장도 있는 것으로 조사되었다. 진주 대평에서 페어리링과 갈색퍼짐병이 발생하였다. 전북고창에서는 페어리링과 테이크올패치가 나타났으며 충북청주에서는 다수의 포장에서 갈색마름병이 관찰되었다. 경기평택에서는 갈색마름병, 도열병, 썸머패취, 커브라리아엽고병, 커브라리아엽고병과 녹조의 복합피해가 나타났다. 전염원 밀도는 장성, 진주, 산청과 남해지역 모두 시간이 지날수록 증가하는 것으로 나타났다. 병 발생과 병원균을 조사한 결과 골프코스에서 나타나는 병해와 유사한 것으로 나타났다.
