Purpose&Contents
○ Development of beneficial microorganisms to control the Sclerotinia rot (Sclerotinia minor) of Aster yomena
○ For the development of potential bacterial strains for controlling of Phytophthora root rot in gom-chwi, we selected antagonistic bacterial strains, analyzed the control efficacy and investigated on biocontrol mechanisms.
○ Development of beneficial microorganisms to control the leaf spot disease of Chwinamul(Aster scaber).
○ Development of beneficial microorganism for control of diamondback moth and investigation of insecticidal efficacy of developed microbial at field

Results
○ The first report of Aster yomena Sclerotinia rot caused by Sclerotinia minor in Korea by Lee S.Y etc..
○ Control efficacy for Sclerotinia rot of Aster yomena by management system of dipping of seedling roots of Aster yomena before planting, drenching in soil after planting, and drenching in soil with 4 times at 7 day interval with 20-fold diluted cultured liquid of Bacillus siamensis 2CON31 and 2CHR35 which isolated from inside Aster yomena was 65.0% and 67.8%, respectively in the greenhouse.
○ A total of 385 bacterial strains were isolated and of which, 49 strains showed antagonistic activity by dual culture assay. Five out of the 49 strains showed dominant suppressive effects on P. drechsleri by seed dipping treatment. Among these strains, ObRS-5 strain showed remarkable antagonism, wherein the control efficacy was 80.1% by seed dipping, 90.5% by soil drenching and 78.1% by root dipping treatments.
○ In the greenhouse experiment, three times treatment had effects on suppression of Phytophthora root rot (53.6-66.2%). The changes of rhizosphere bacterial community structure resulted from treatment of ObRS-5 strain and the relative abundance was increased in Bacteriodetes phylum and Cellvibrio and Pseudomonas genus. Treatment of ObRS-5 strain resulted in inhibition of zoosporangia formation at 87.4-100%, zoospores germination at 6.4%–90.4% and enhancement plant defense gene expression.
○ Selection of Paenibacillus polymyxa JE201 with antifungal activity against fungal leaf spot disease of Aster scaber
- Control effect of leaf spot disease was 62.4%
○ We selected high virulent entomopathogenic fungi Metarhizium anisopliae FT319, Isaria javanica FT337 against diamondback moth, established proper fermentation condition and investigated insecticidal efficacy of two selected isolates at field.

Expected Contribution
○ producing high-quality safe Aster yomena. by eco-friendly control on Sclerotinia rot using microbial agents
○ Improvement of eco-friendly production technology of wild vegetable, gom-chwi plants using useful agricultural bacteria which can contribute of controlling of Phytophthora root rot.
○ Utilize result for technical guidance and consulting at farm
○ Improve of commercialization of technology by sharing research results with industry.
