  • The study was conducted to obtain the basic information on the diseases epidemics of vegetable crops grown in Namji, Jinju, Gimhae and Suncheon under the extremely varied and specified conditions, plastic film house. The disease survey was conducted from the end of April, 1951 to April 1982. Leaf mold and late blight were serious foliar disease in tomato during the seedling stage, especially when the infected seeds were sown. The diseases increased rapidly 35 days after seeding. In both continuous cultivation of cucumber and rotation with upland crops, incidence of Fusarium wilt was severe while incidence of the disease was negligible in cultivations after paddy rice or grafting on pumpkin. Downy mildew of cucumber was severe in Jinju and Suncheon area, however, it was not so serious in Namji area where the growing season of cucumber was unfavorable for the maximum disease incidence. Cucumber mosaic virus disease was prevalent in the areas surveyed and the disease incidence was increased rapidly after June. Powdery mildew prevailed at the early stage of cucumber growth after transplanting in Namji area. Root rot and wilting caused by Phytophthora capsici was as the most destructive disease in pepper grown under the vinyl house, especially in Namji and Jinju area where the pepper has been cultivated intensively. The Phytophthora attacked most parts of young plants during the winter time and then induced crown rot on the adults plants. Cultivation of pepper in vinyl house was almost impossible because of the Phytophora disease by the end of June. Virus diseases to tomato plants were prevalent throughout the surveyed area and the damage was also severe. In Jinju and Gimhae area leaf mold and late blight showed high infection rate in tomato during the harvest time.

  • This study investigated the present traditional Korean farmhouse based on a survey of 30 households from Oiam-Ri folk Village in Chung-Nam Province. This study was primarily concerned with the present housing; the size and plan of the house, lighting and heating, the finishing materials of anbang(the master's bedroom or ondol) and the kinds of fumiture. I was also interested in identifying the socio-demographic and physical variables that influenced the housing, both the ordinary farm households and the descendent of nobility households. Bibliographical studies, cultural approaches, field surveys with tape recordings, and questionnaires were used to collect the data. The results showed that the types of house plans were mixed from the southern region(one-line type) and middle region(courtyard type). The heating system and the fuel for the ondol anbang has changed entirely from wood burning system to oil boiler system. The finishing material of the anbang floor changed from traditional oil paper and straw mats to vinyl flooring. Traditional fumiture and small decor items are disappearing and are being replaced by modem items, but the descendents of the nobility household kept many traditional type of fumiture and small decor items.

  • Occurrences of virus diseases on paprika ( Capsicum annuum var. grossum) were surveyed in Joennam province from 1999 to 2003 and the collected samples showing virus-like symptoms were tested using ELISA. Virus diseases appeared 4.5%, 17.5%, and 4.9% in 2000, 2002, and 2003, respectively. As the results of investigation of the seasonal incidence with the growing stages of plant, virus was not occurred at seedling stage and was slightly from the planting time to the first harvesting time, but was dramatically increased at the second harvesting time. Virus diseases were more severe on the vinyl house than on the green house. Pepper mild mottle virus (PMMoV) was severely occurred in 2000 but not after that year. Comparing the virus species, Pepper mottle virus (PepMoV) was 35.9%, Broad bean wilt virus (BBWV) was 14.1%, and Cucumber mosaic virus (CMV) was 10.9% in 2002, and 76.0%, 11.1%, and 2.4% in 2003, respectively.

  • The purpose of this study was to find out the physical change of the farm house and its anbang(the main room : master bed room), to identify the behavioral changes : activity and awareness of anbang, and to clarify the relationship between the physical changes of the farm house, and the behavioral changes of housing life-style in the anbang space. Bibliographical studies, cultural approaches and field survey method with questionnaire were used to collect data from 55 residents of Anwhari and Yangkyori in Pyong Teck Koon. Tables and drawings were made to analyze the data. The major findings were 1) the heating system of the ondol anbang. The most popular type is the double heating system(new pipes added to the traditional ondol). This combination ondol system brought some conviniences to the farmers. This change in structure of the ondol were of four types : Complete change in style, enlarged-completely changed style, partially changed style, enlarged-partially changed style. 2) from 1960 through 1970 lighting of the anbang changed room oil lamp to electricity. 3) the finishing material of the anbang floor changed from traditional oil paper and straw mats to vinyl flooring. 4) Traditional furniture and small decor items are gradually disappearing and are being replaced by modern items. 5) The awareness and actual use of the ondol anbang has not much changed from the multi-functional and sacred space of daily living : which are the characteristics of Korean traditional ondol anbang. The biggest consistency in the ondol anbang is the heating system of the floor, which is the characteristic of ondol culture in Korea. This system will continue regardless of time and place in Korea.

  • Yellow spot or blotch symptoms on the upper surface of leaf, without the production of velvet-like fungi on the lower surface of leaf as in the gray mold of tomato caused by Cladosporium fulvum, were observed in tomato (cv. Seokwang) plants in May, 1995, in a vinyl-house of the experimental plot of Gyeongnam Provincial Rural Development Administration, Chinju, Gyeongnam, Korea. We identified this disease as powdery mildew of tomato caused by Oidiopsis taurica (L v.) Arnaud (=Leveillula taurica), which was new to Korea. Conidia of the fungus were borne on uni- or bi-septated conidiophores which were developed through the stomata of the tomato leaf. The conidia were slender, clavate and variable in size (31~111.6$\times$13.1 ${\mu}{\textrm}{m}$). The fungal conidia isolated from tomato leaves were inoculated to tomato plants, and the occurrence of the same disease was confirmed based on the symptomatology and the morphology of the pathogen reisolated.

  • A new bacterial disease was found on leaves of Kalanchoe blossfeldiana plant grown under vinyl-house condition in winter of 1998 in Taejeon. the first symptoms of the disease are the appearance of the water-soaked and light brown spots. Later they become soft rot with brown color. Causal bacteria were isolated from diseased tissues and the same symptoms as the natural infection were developed on Kalanchoe blossfeldiana leaves by needle-prick inoculation. The causal bacterium was identified Erwinia hervicola by its bacteriological characteristics. This is the first reported of this bacterium to occur on kalanchoe blossfeldiana plant in Korea. Therefore, we proposed to name the diseases as \"bacterial soft rot of Kalanchoe blossfeldiana\" by E. herbiocla.

  • Biocontrol of plant pathogens provides an alternative means of reducing the incidence of plant diseases without the negative aspects of chemical pesticides. Nowdays, as the resistant fungi about the chemical fungicides have revealed and the concern of environment has increased, the biological control of phytopathogenic fungi by the antagonistic microorganisms is very much indispensable. For the selection of strong antagonistic bacterium for biological control agent of rice leafblast and cucumber gray mold rot, the antifungal strain KL-3 strain was selected among 120 strains isolated from the rhizosphere soils. And the strain was identified to be a species of Bacillus subtilis or closely related strain. In several biochemical and in vitro antibiosis tests, antifungal substances of Bacillus sp. KL-3 were presumed heat stable, micromolecular antibiotic substances. In vivo test and vinyl house field test, the antifungal substances of Bacillus sp. KL-3 represented excellent biocontrol ability aganist Alternaria mali, Phyricularia oryzae, and Alternaria kikuchiana as well as broad spectrum of other fungi. In particular, Bacillus sp. KL-3 strain showed more predominant activity than some chemical fungicides against fungi shown to resist chemcal fungicides.
