국내 주요 인삼재배 산지 기반을 가진 전북 진안지역의 인삼 홍삼산업은, 재배농가 895호, 재배면적 402ha, 생산량 1,628톤, 홍삼가공업체 80개소, 판매업소 50개소로 지역경제의 25% 이상을 차지한다. 그러나 재배농가의 계열화 미흡(22%), 산지수집상(포전매매)에 의한 인근 유사 도매시장으로 재배물량과 부가가치 유출(78%), 가공시설의 노후화, 가공업체의 영세성(매출규모 연평균 2억11백만원)과 함께 중국, 캐나다, 미국 등의 국제 가격경쟁과 국내의 대기업 및 인삼산업 주요지역과의 경쟁이라는 상황에 직면하고 있다. 이러한 상황을 극복하고 지역특화명품산업으로 발전할 수 있는 방안으로, 인삼재배산지로서 원료공급지를 기반으로 하는 재배, 유통, 가공, 품질관리, 시설분야에 이르는 발전방안을 연구하였다. 산업원료 확보를 위해서는 인삼계열화 확대를 통해 원물 확보력을 강화하여야 한다. 재배분야의 경우에는 친환경재배 확대와 GAP 확대를 통해 원물의 품질경쟁력 뿐만 아니라 시장수요에 따른 브랜드마케팅 요인으로 특성화해야 한다. 유통분야는 계열화 확대를 통한 원물확보라는 산업경쟁력을 바탕으로 원료중심의 수취, 매취, 보관, 가공, 대형거래, 도소매 등 유통활성화와 유통규격포장 및 선별등급표준화를 통한 유통표준화를 추진하여야 한다. 가공의 경우, 원료홍삼 공급기능을 중심으로 가공산업을 선택 육성해야한다. 품질관리는 원물중심관리(성분, 잔류농약, 식품위생), 유통중심관리(연근, 등급), 경작중심관리(재배지, 재배자, 경작), 프로세스중심관리(재배 유통 가공 판매정보)로 구체화해야한다. 시설분야는 유통시설(대규모 집하시설, 보관시설 등 종합유통처리시설)과 가공시설(가공설비현대화, 가공공장 공인규격화;ISO, GMP, HACCP)의 지속적인 시설개선과 현대화를 추진하여야 한다.

BACKGROUND: It is hard to control the agricultural products exceeding MRL (maximum residue limit) before forwarding. Therefore, NAQS (National Agricultural Products Quality Management Service, South Korea) established PHRL (pre-harvest residue limit) on agricultural products during their cultivation periods. This study was performed to set the PHRLs of peach during cultivation period, and also to estimate biological half-lives for residues of clothianidin and fluquinconazole. METHODS AND RESULTS: Two groups of peach were treated under Korean GAP (Good Agricultural Practices) with application time, single and triple treatments. Sample was collected over 14days (each after 0, 2, 4, 6, 8, 10, 12, 14 days. 8times), and clothianidin and fluquinconazole were analyzed by HPLC/DAD and GC/ECD, respectively. CONCLUSION: The biological half-life of clothianidin in single treatment and triple treatment was 5.2days and 7.0days. That of fluquinconazole was also 3.9days and 4.1days, respectively. The PHRL of peach on 10days before harvest was 1.4 mg/kg in clothianidin and 1.8 mg/kg in fluquinconazole.

BACKGROUND: The healthy food trend has encouraged the consumption of natural products, including berries. This trend is expected to increase the strawberry consumption. There has been a concern about the exposure of pesticides approved for use on strawberry. In this study, the dissipation patterns of systemic and non-systemic pesticides were evaluated in strawberry under plastic-covered greenhouse conditions. METHODS AND RESULTS: Cyflumetofen and dimethomorph were applied on strawberry in the critical GAP (Good Agricultural Practices). Strawberries were harvested at 0, 1, 2, 3, 5, 7 and 10 days after final application of the pesticides. The analyses of the residual pesticides were performed by HPLC-DAD with C18 column. The limits of quantitation (LOQ) of cyflumetofen and dimethomorph were 0.04 and 0.02 mg/kg, respectively. The recovery of cyflumetofen and dimethomorph were 88.1 ~ 103.3% and 79.0 ~ 110.2% for the spiked two levels (LOQ and 10LOQ), respectively. The biological half-lives of cyflumetofen and dimethomorph werer 7.5 and 8.9 days, respectively. The dissipation rates in strawberry were calculated by the statistics method at a 95% confidence level. The distribution showed that pesticides with low log Pow were indicated by the decreased dissipation rate and pesticides with similar log Pow and low solubility also showed the decreased dissipation rate. CONCLUSION: The residues of cyflumetofen and dimethomorph in strawberry at time 0 after the final application were below the established MRL in Korea. The dissipation behavior of systemic and non-systemic pesticides in strawberry is affected by their log Pow and water solubility values.

The purpose of this study was to analyze microbiological hazards for plants, cultivation environments and personal hygiene of perilla leaf farms at the harvesting stage. Samples were collected from three perilla leaf farms(A, B, C) located in Gyeongnam, Korea and tested for sanitary indications, fungi and pathogenic bacteria(Escherichia coli O157:H7, Listeria monocytogens, Salmonella spp., Staphylococcus aureus and Bacillus cereus). As a result, total bacteria and coliform in perilla leaf were detected at the levels of 4.4~5.2 and 3.4~4.3 log CFU/g, respectively, but E. coli was not detected in all samples. Among the pathogenic bacteria, B. cereus(perilla leaf: 2.0~2.4 log CFU/g, stem: 1.4~2.1 log CFU/g, water: 0.7 log CFU/ml, soil: 4.2~5.0 log CFU/g, hands: 3.0 log CFU/ hand, gloves: 2.1~2.4 log CFU/100 $cm^2$, glothes: 1.5~2.8 log CFU/100 $cm^2$) and S. aureus(3.4 log CFU/hand) were detected in all samples and worker's hand from farm A, respectively. However, other pathogenic bacteria were not detected. This study demonstrates that perilla leaf at the harvesting stage was significantly contaminated with microbial hazards.

This is a survey on farming activities of intensive major course's graduates of Korea National College of Agriculture and Fisheries(KNCAF). Above all, major characteristics of graduates of intensiv major course cases are as follows. First, They make an effort to secure of agriculture competitiveness through an increase in farm size, and then strive for their specialty. Second, They are leading value based agriculture through an innovations in techniques. According to analysis results, intensive major course's examples have the following features: aim at environmentally-friendly agriculture, actively introduction of new technology, continued research activity, community reinvigoration and leading development of agriculture through active network. Finally, This result in various certifications and awards(environment friendly certification, HACCP certification, non antibiotic/pesticide-free certification, organic certification etc.). Therefore, there are necessity of various intitutional and political supports in order that they grow the core people and leader of farm village.

This study was performed to investigate effect of different soil managements on physical properties and microbial activities in volcanic ash citrus orchard soil. Experiment plots had managed to control weeds on soil for 4 years with clean cultivation (CCM) used with herbicide, natural sod cultivation (NSCM), kentucky blue grass sod cultivation (KBG). Soil samples were taken on October, in both 1998 and 2000 from 3 experimental plots. In NSCM, Soil hardness was lower at 11.8 mm than in CCM. And water stable Aggregation coefficient(>0.5 mm) was high at 26.7% compared with CCM. Soil bulk density and porosity showed no significant among the treatments. Soil acid phosphatase was high in sod cultivation plots and the amount of microbial biomass C was about twice higher at $525.4mg\;kg^{-1}$ in KBG than in CCM. Conclusionally, Sod cultivation improved soil physical properties such as aggregation, hardness and increased microbial activities compared with clean cultivation in citrus orchard soil. Soil total PLFA, acid phosphatase, and microbial biomass C contents were investigated on May in nonvolcanic ash citrus soil. Soil samples were collected at 5 sites each; convention cultivation grown with herbicide, natural sod cultivation grown with 1/2 chemicals, organic cultivation. That sites have been managed for 5 years over. PLFA contents were two times higher at $112.2n\;mol\;g^{-1}$ in organic cultivation than in convention cultivation. According to the PLFA indicator, Gram negative bacteria and actinomycetes in organic cultivation were high compared with convention cultivation, which were at 15.1%, 6.6%, respectively. Soil microbial biomass C contents was about twice higher in organic cultivation than in convention cultivation. Soil acid phosphatase was high at 17.6% in organic cultivation compared with convention cultivation.
