Simple Detection of Cochliobolus Fungal Pathogens in Maize
In Jeong Kang, Hyeong Kwon Shim, Jae Hwan Roh, Sunggi Heu, Dong Bum Shin 한국식물병리학회 The Plant Pathology Journal 8 Pages
한국식물병리학회 The Plant Pathology Journal 2018, 34권 4호 7 327-334 (8 pages)
Northern corn leaf spot and southern corn leaf blight caused by Cochliobolus carbonum (anamorph, Bipolaris zeicola) and Cochliobolus heterostrophus (anamorph, Bipolaris maydis), respectively, are common maize diseases in Korea. Accurate detection of plant pathogens is necessary for effective disease management. Based on the polyketide synthase gene (PKS) of Cochliobolus carbonum and the nonribosomal peptide synthetase gene (NRPS) of Cochliobolus heterostrophus, primer pairs were designed for PCR... -
Research Articles : A Three-Year Field Validation Study to Improve the Integrated Pest Management of Hot Pepper
한국식물병리학회 The Plant Pathology Journal 11 Pages
한국식물병리학회 The Plant Pathology Journal 2013, 29권 3호 8 294-304 (11 pages)
To improve the integrated pest management (IPM) of hot pepper, field study was conducted in Hwasung from 2010 to 2012 and an IPM system was developed to help growers decide when to apply pesticides to control anthracnose, tobacco budworm, Phytophthora blight, bacterial wilt, and bacterial leaf spot. The three field treatments consisted of IPM sprays following the forecast model advisory, a periodic spray at 7-to-10-day intervals, and no spray (control). The number of annual pesticide... -
A Forecast Model for the First Occurrence of Phytophthora Blight on Chili Pepper after Overwintering
한국식물병리학회 The Plant Pathology Journal 13 Pages
한국식물병리학회 The Plant Pathology Journal 2012, 28권 2호 6 172-184 (13 pages)
An infection risk model for Phytophthora blight on chili pepper was developed to estimate the first date of disease occurrence in the field. The model consisted of three parts including estimation of zoosporangium formation, soil water content, and amount of active inoculum in soil. Daily weather data on air temperature, relative humidity and rainfall, and the soil texture data of local areas were used to estimate infection risk level that was quantified as the accumulated amount of active... -
경기육괴 북서부 영흥도-선재도-대부도에 분포하는 변성퇴적암 내 쇄설성 저어콘의 SHRIMP U-Pb 연대

경기육괴의 북서부에 위치한 영흥도-선재도-대부도는 지구조적 중요성에도 불구하고 지질 및 지질연대 자료가 거의 없는 지역이다. 우리는 이 지역에 산출하는 변성퇴적암의 암상과 쇄설성 저어콘의 U-Pb 연대를 밝히는 연구를 수행하였다. 연구 지역의 변성퇴적암은 대부분 규암-변성사암 및 규암과 편암의 호층대로 이루어져 있으며, 규암 역을 포함하는 석회질 역질 사암, 석회질 편암 그리고 변성이질암이 소규모로 산출한다. 변성이질암에는 석류석 반상변정이 두드러지게 산출하며, 변성이질암 내의 석영맥에서는 남정석 또는... -
Research Articles : Genetic Compositions of Broad bean wilt virus 2 Infecting Red Pepper in Korea
한국식물병리학회 The Plant Pathology Journal 11 Pages
한국식물병리학회 The Plant Pathology Journal 2013, 29권 3호 6 274-284 (11 pages)
The incidence of Broad bean wilt virus 2 (BBWV2) on red pepper was investigated using the samples obtained from 24 areas of 8 provinces in Korea. Two hundred and five samples (79%) out of 260 collected samples were found to be infected with BBWV2. While the single infection rate of BBWV2 was 21.5%, the coinfection rate of BBWV2 with Cucumber mosaic virus, Pepper mottle virus, Pepper mild mottle virus and/or Potato virus Y was 78.5%. To characterize the genetic diversity of BBWV2 Korean isolates,...
