This paper aims to provide the basic data about the uses of agricultural products related to food, cloth and shelter in the late Joseon Dynasty by analysing$\ulcorner$Kyuhap-Chongseo$\lrcorner$(1809). The results of this study are as follows: 1. The agricultural products related to cloth, food and shelter were of 95 species total(horticultural crops 37.9%, industrial crops 22.1%, food crops 13.7%, floricultural crops 13.7%. and animal products 12.6%). 2. The agricultural products(24species) related to clothing were used for weaving, dyeing, laundering and starching textiles. 80 species of agricultural products were used as ingredients in about 140 dishes. As for shelter, the agricultural products(30species) were used for making stationaries. managing vessels and illumination, and building structures.

Solanaceous crops grown in greenhouses and fields in Korea were surveyed from 1994 to 2000. Sclerotinia rot most severely occurred up to 60% in potato. Incidence of the disease was as high as 20% at its maximum in tomato and 5% in eggplant, but as low as less than 1% in red pepper. Symptoms of Sclerotinia rot commonly developed on stems of the solanaceous crops but rarely on fruits of eggplant and tomato. A total of 169 isolates of Sclerotinia species was obtained from the diseased solanaceous crops. Out of the isolates, 165 isolates were identified as S. sclerotiorum, and the others as S. minor based on their morphological and cultural characteristics. S. sclerotiorum was isolated from all the solanaceous crops, while S. minor was only isolated from tomato. Eight isolates of S. sclerotiorum and two isolates of S. minor were tested for their pathogenicity to the solanaceous crops by artificial inoculation. All the isolates of the two Sclerotinia spp. induced rot symptoms on stems of the solanaceous crops tested, which were similar to those observed in the fields. The pathogenicity tests revealed that there was no significant difference in the susceptibility of the solanaceous crops to the isolates of S. sclerotiorum. However, in case of S. minor, the potato cultivar Sumi was relatively less susceptible to the pathogen.

Four leguminous crops grown in greenhouses and fields in Korea were surveyed from 2000 through 2002. Sclerotinia rot most severely occurred up to $60\%$ in Phaseolus vulgaris grown in greenhouses but occurred as low as $0-0.5\%$ in that grown in fields. Incidence of the disease in Pisum sativum grown in greenhouses ranged $1-5\%$, and that in Vicia Java and Vigna sinensis grown in fields was $0.8\%$ and $2\%$, respectively. Symptoms of Sclerotinia rot commonly developed on stems and pods of the crops. A total of 59 isolates of Sclerotinia species were obtained from diseased stems and pods of the crops. All of the isolates were identified as Sclerotinia sclerotiorum based on their morphological characteristics. Eight isolates of the fungus were tested for their pathogenicity to four host crops by artificial inoculation. All of the isolates induced rot symptoms on stems of the host crops tested, which were similar to those observed in the fields. The pathogenicity tests revealed that there was no significant difference in the susceptibility to the isolates among the leguminous crops tested This is the first formal report that S. sclerotiorum causes the Sclerotinia' rot of the four leguminous crops in Korea.

The coexistence policy of GM and non-GM crops is still on the debates in EU since “the recommendation on guidelines for the development of national strategies and best practices to ensure the coexistence of GM crops with conventional and organic farming” has been reported in 2003. The major issues are maximum tolerance level of GMO admixture and minimum isolation distances of GM fields with others including conventional, organic and seeds production. Majority of member states in EU proposed that the tolerance level of GMO admixture must be more strictly controlled, in particular in the fields for organic crops and seeds production. To this end, it was proposed that minimum isolation distances to segregate GM crops from fields with organic crops and seeds production need to be further extended than those of conventional crops since cross pollination with other crops adjacent GM fields is known as the most prevalent source for GMO contamination. In these circumstances, it is strongly suggested that the current legislations need to be revised including the minimum isolation distances of fields for each species before field cultivation for a commercial GM crop is approved for the first time in South Korea.

An extrapolation of residue data of seven commonly used pesticides namely bifenthrin, chlorothalonil, cypermethrin, diazinon, fenvalerate, phenthoate and procymidone on a total of 22 minor crops has been carried out in an experimental field trial. The pesticides were applied to 11 leafy-, 5 root- and 6 stem-crops grown in the experimental green-house and the crops and plants were randomly collected at 1, 3, 5, 7 days after application. The average recoveries of applied pesticides were ranged from 72.0 to 117.0% in leafy crops, from 81.3 to 105.0% in stem crops and from 70.1 to 108.1% in the root-crops. Limits of detection (LODs) were 0.005-0.1 mg/kg in the leafy crops and 0.001-0.005 mg/kg in both the stem & root crops. Based on the results of residual dissipation pattern and their morphology, all crops were classified into high and low residual groups. The results showed that it might be possible to extrapolate residual data of stem-crops to root-crops within the same group. Crops that have currently no registered pesticide for use, would be possible to use the pesticides which are already been registered for the similar crops.

Objective : The study was for researching the activation methods about Korean overall medical crops business from 2010 to 2016. In addition, it was to be given to examining complement points and improving methods to the changeable domestic market of medical crops caused by a considerable export-import amount of them. Methods : By examining and analyzing data for the trend of medical crops production and their export-import trend from 2010 to 2015, I found it valuable to use it as the basic resources for researching the urgent problem of medical crops' business and its improvement. Results : 1. As surveying the trend of the domestic medical crops over the recent six years, I found that the export amount of them has drastically decreased, while the import amount has increased. And so, the prices of the domestic medical crops and their production are unstable. 2. By developing standardized medical crops which a trading counterpart country could prefer, we have to promote the export competitiveness. 3. We should reinforce an origin mark and geographical mark practice for domestic herbal materials and expand GMP. 4. We should prepare a standardization of herbal medicines by setting up an independent governmental department. Conclusion : 1. The government should present an appropriate supply-demand amount of the medical crops depending on the domestic needs and the export-import transactions. 2. There should be an institutional supportive system which is able to guarantee stable incomes of farmers through contract cultivation. 3. We should develop high value standardized medical crops.
