We screened preventives (preventers) from natural resources to prevent the rust phenomenon in ginseng roots. We examined that how these influence on the rusty phenomenon and the growth of 2 years old ginsengs treated in the preventers. All treats which was compounding preventers & improvers were so excellent of the ginsengs growth. Especially, the growth of 2 years old ginsengs treated with bio-preventer of ICPE-C105 and ICPE-P107R were increased to 73%, 28% compared with nontreatment, respectively. Though rusty ginseng of rate was emerged 58% in control, preventers ICPE-C 105 and ICPE-P107 were emerged of each 16.7%, 20%. It was affirmed effective of preventer. On the other hands, amounts of ginsenoside treated with preventatives showed to be changed. The total ginsenoside was increased to 71% with treatment ICPE-C105R which is the highest among groups compared to control, and ICPE-P$\_$107/R was increased to 50%. To sum up with total results, it is biotic preventatives (ICPE-C$\_$105/R and ICPE-P$\_$107/R) which we created improve both a high yield of ginseng roots and the inhibition of the rusty phenomenon. phenomenon.

We screened biotic and abiotic preventative,i(preventers) from natural resources to prevent the rusty phenomenon in ginseng roots. To select preventatives(preventers), soil microbes such as Agrobacterium and certain microbes isolated from the rusty ginsengs and the soil in which the rusty ginsengs were planted and used. It is also performed with germination tests of the seeds of Latuca Sativa L. We identified that how selected preventatives(preventers) effect the germination of ginseng seeds. Furthermore, how these influence on the rusty phenomenon and the growth of 1 -year-old ginsengs treated in the pavement. The final preventatives; ICPE-C1$\sub$05/, ICPE-P$\^$107/ were effective in not only the growth of ginseng, but also inhibition of the rusty phenomenon. Moreover, we selected abiotic soil improvers; called P, R, and W, respectively; to promote the effects of preventatives. R and W was excellented among choring improvers. The germination rate of 2-year-old ginsengs treated with ICPE-C$\sub$105/P, and ICPE-P$\sub$107/P was the highest under the effects of naturally selected preventatives mixing with abiotic soil improvers. All treat which was compounding preventers & improvers were so excellented of growth ginseng. Especially treats of ICPE-C$\sub$105/R and ICPE-P$\sub$107/R showed growth increased of each 67.3% and 52.7% As well, the growth of ginseng was the highest in the treatment of ICPE-C$\sub$105/R, and ICPE-P$\sub$105/R. Though rusty of rate was emerged 35% in control, preventers ICPE-C$\sub$105/R and ICPE-P$\sub$107/R were emerged 5.3%. It was affirmed effective of preventer. On the other hands, amounts of ginsenoside treated with preventatives showed to be changed. The ginsenoside was increased to 14.2% with treatment with ICPE-P$\sub$107/R which is highest among groups compared to control, and ICPE-C$\sub$105/P was increased to 5.0%. To sum up with total results, it is judged that biotic preventatives (ICPE-C$\sub$105/R, and ICPE-P$\sub$107/R) which we created improve both a high yield of ginseng and the inhibition of the rusty phenomenon. phenomenon.
