Background and objective: This study was conducted as part of research to promote garden diversity and seek sustainable garden management plans, as well as to determine the trends in understanding and use of companion plants as an eco-friendly farming method and provide the results as the basic data for sustainable urban agriculture. Methods: To determine the trends in garden activities, eco-friendly pest control, and use of companion plants, a survey was conducted on 230 urban residents participating in the Urban Agriculture Expert course. 223 copies of the questionnaire were collected excluding missing values, and IBM SPSS statistics Ver. 25 Program was used for frequency analysis, descriptive statistics, and regression analysis. Results: Most of the respondents were female (71.3%), homemakers (26.5%), were in their 50s (29.1%), and had 2 members in the family (27.8%). 164 respondents (73.5%) had experience in gardening, most of them once a week (31.7%) and for self-consumption (55.5%). Both men and women raised crops for safe food production (32.3%), and they most preferred the city garden type (39.9%). For the preparation of nourishment for eco-friendly garden management, most respondents (60.1%) purchased fertilizers from the market. For the reason why eco-friendly pest control is necessary, all respondents except 4 of them (98.2%) responded that it is necessary 'because it affects my health as I eat it (73.5%)', indicating that they still had a high level of interest in health. Only 43.9% of the respondents said that they had heard of companion plants, 89.2% responded that companion plants were effective in eco-friendly management, and 87.4% showed the will to participate in gardening using companion plants in the future. Finally, the regression analysis confirmed that the awareness of companion plants and satisfaction with gardening activities are key variables that increase the intention to participate in gardening activities in the future. Conclusion: Since plants require special care depending on the period and various diseases and insect pests occur, there must be continuous research on companion plants as an eco-friendly farming method. Moreover, by actively using companion plants in urban gardens with the utility value in not only eco-friendly pest control but also in helping plant growth, urban agriculture is expected to be continuously activated and promoted by increasing satisfaction in gardening activities with aesthetic landscaping and pest control.

This study was conducted to investigate the influence of eco-friendly restoration in forested bog on the structure of benthic macroinvertebrate community. The benthic macroinvertebrates collected from the surveyed sites were composed of 1,071 individuals, 60 species, 40 families, 13 orders, 6 classes and 5 phyla. At the control and Site 3(small dam), the number of species and individuals were larger than that of other sites, and EPT group ratio was same as well. Considered by index, the dominance index (DI) was found the highest at the biotope area. The diversity index (H') and richness index (RI) were the highest at the control and Site 3. In addition, the ecological score of benthic macroinvertebrate (ESB) showed the highest at site 3, while the lowest at biotope area. The stability and recovery of benthic macrointebrates showed different according to restoration types at forested bog. After restoration project, the benthic macroinvertebrates were observed to get recovery at Site 3, and to have the highest communities stability at control and Site 3. At biotope areas (Site 4, Site 5 and Site 6) communities stability were the lowest, but showed different community stability values according to the presence of water. It is confirmed that the eco-friendly restoration projects indeed provided the better environment for the inhabitation of benthic macroinvertebrate community. The change of community index depending on the restoration projects suggests that the eco-friendly restoration can provide a more suitable environment for benthic macroinvertebrate ecosystem that prefers the stream environment.

Recently, the rate of cultivation of such as hairy vetch was increased as a way of reducing the current soil problem. However, the occurrence of insect pest such as bean bugs, Riptortus pedestris, were increased in the field of green manure crops and their injuries to hairy vetch were observed. While minimizing insecticide use for the environmental friendly agriculture, the control of the bean bug can be utilized environmental friendly agricultural materials (EFAMs) in the green manure crop fields. The control effects of some EFAMs and most of chemical insecticides to the bean bug were significantly high. As a result of direct spray of EFAM that contained sophora extract or neem extract, the control effects of six EFAMs were higher than 70% at 120 hours after treatments. Among them, three EFAMs were showed over 90% of control effects. On the other hand, most of chemical insecticides were showed 100% of control effect against the bean bug at 48 hours after treatment. As mortality effects of EFAMs were sloely observed until 120h after treatment, we must use selected EFAMs at the beginnibgs of occurrence and entrance in the field of green manure for effective control of bean bugs.

Melanose, caused by Diaporthe citri, is one of severe diseases in citrus, a major economic resource in Jeju island. To reduce the usage amount of organic synthetic fungicide, bio-sulfur was tested as an alternative chemical to control citrus melanose in the present study. Direct antifungal activity of bio-sulfur against D. citri was determined through in vitro experiment using artificial nutrient media. Disease severity of melanose on bio-sulfur pretreated citrus leaves was lower than that on untreated ones. To illustrate the mechanism of disease suppression by bio-sulfur, infection structures were observed with a fluorescent microscope and a scanning electron microscope. In fluorescent microscopic observation, most conidia rarely germinated. In addition, hyphal growth on leaves pretreated with bio-sulfur was inhibited compared to that on untreated ones. In scanning electron microscope images of bio-sulfur pretreated leaves, surfaces of most conidia were shrunk while hyphae were morphologically changed and frequently branched. Such microscopic observations were also found for leaves pretreated with a commercial fungicide Dithianon. These results suggest that bio-sulfur may be used to control citrus melanose as an environment friendly alternative to organic synthetic fungicides

무당벌레(H. axyridis)는 세계적으로 진딧물의 포식자로 널리 알려지면서 농생태계내에서 진딧물을 방제하기 위한 방제인자로 많이 사용하고 있다. 또한 국내에서는 농약의 사용을 억제하는 정부정책과 소비자의 요구 등으로 인하여 친환경농업이 확대되면서 친환경농자재들이 많이 사용되고 있다. 따라서 친환경농자재의 사용은 무당벌레에 직간접적으로 영향을 미칠 수가 있다. 살충성친환경농자재(IEFAMs)의 경우 무당벌레의 각 발육단계에 대하여 대부분 안전한 경향을 나타내고 있다. 살균성친환경농자재(FEFAM)의 경우에도 FEFAM A를 제외한 다른 종류들은 무당벌레에 대하여 영향이 적다. 토양미생물친환경농자재(EFAMSM)인 EFAMSM C와 H는 무당벌레 알의 부화율을 떨어뜨릴 수가 있으며, EFAMSM A와 F는 1령 유충에 피해를 줄 수 있는 것으로 조사되었다. 식물성추출물친환경농자재(EFAMPE)는 EFAMPE A와 D는 무당벌레 알에 치명적인 독성을 보이고 있는 것을 알 수 있다. 그 이외의 다른 조사된 농자재들은 무당벌레에 비교적 독성이 약한 것으로 평가되었다.
