Altering Conidial Dispersal of Alternaria solani by Modifying Microclimate in Tomato Crop Canopy
한국식물병리학회 The Plant Pathology Journal 11 Pages
한국식물병리학회 The Plant Pathology Journal 2016, 32권 6호 3 508-518 (11 pages)
Early blight of tomato caused by Alternaria solani, is responsible for severe yield losses in tomato. The conidia survive on soil surface and old dry lower leaves of the plant and spread when suitable climatic conditions are available. Macroclimatic study reveals that highest inoculum concentration of Alternaria spores appeared in May 2012 to 2013 and lowest concentration during January 2012 to 2013. High night temperature positively correlated and significantly (P ; 0.01) involved in conidial... -

Eight potato-producing provinces of Iran were surveyed during the growing seasons of 2004?2006 to detect the presence of Tomato yellow fruit ring virus (TYFRV), a tentative species in the genus Tospovirus. A total of 1,957 potato leaf samples were collected from plants with tospovirus-like symptoms of chlorotic or necrotic spots, chlorosis and necrosis. The samples were tested by enzyme-linked immunosorbent assay using TYFRVspecific antibodies. Among those tested, 498 samples (25.4%) were found... -

벼 담수직파재배의 파종적기와 만한기를 농업기후지대별 기후자료 분석하여 결정하고자 기상청의 56개 기상관측지점의 유효기온출현특성을 분석하였다. 일평균기온 15$^{circ}C$ 출현시기를 파종조한기 결정의 유효기준온도로 하고, 농촌진흥청의 작황진단시험 결과를 이용하여 파종기부터 출수기까지의 출수생태형에 따른 적산온도를 결정하여, 벼 담수직파 안전재배 시기를 설정한 결과는 다음과 같다. 1. 일평균기온 15$^{circ}C$의 출현시기에 따른 파종조한기는 남해지역이 4월24일로 가장 일렀고, 대관령지역이 기장 늦은 6월6일로... -
Characterization of the Maize Stalk Rot Pathogens Fusarium subglutinans and F. temperatum and the Effect of Fungicides on Their Mycelial Growth and Colony Formation
한국식물병리학회 The Plant Pathology Journal 10 Pages
한국식물병리학회 The Plant Pathology Journal 2014, 30권 4호 7 397-406 (10 pages)
Maize is a socioeconomically important crop in many countries. Recently, a high incidence of stalk rot disease has been reported in several maize fields in Gangwon province. In this report, we show that maize stalk rot is associated with the fungal pathogens Fusarium subglutinans and F. temperatum. Since no fungicides are available to control these pathogens on maize plants, we selected six fungicides (tebuconazole, difenoconazole, fluquinconazole, azoxystrobin, prochloraz and kresoxim-methyl)...
