Abstract:
PURPOSE: A microbial agent containing Bacillus subtilis R2-1 or a culture medium thereof for preventing powdery mildew, and a prevention method using the same are provided to effectively prevent powdery mildew with an eco-friendly method. CONSTITUTION: A microbial agent for preventing powdery mildew contains Bacillus subtilis R2-1(deposit number: KACC 91542P) or a culture medium thereof. The culture medium contains rice or barley. The culture medium also contains: a liquid fertilizer of fish amino acid, humic acid, and molasses in a ratio of 1:8-12:8-12, or a liquid fertilizer of fish amino acid, glucose, and molasses in a ratio of 1:3-7:8-12; 1-3 wt% of molasses, 0.1-3 wt% of glucose, and 0.01-0.5 wt% of soytone; and an organic fertilizer which contains 4-6 wt% of nitrogen, 1-3 wt% of phosphoric acid, 0.3-2 wt% of potassium(40-50 wt% of caster bean waste, 30-50 wt% of rape seed waste, 8-12 wt% of rice bran, and 3-7 wt% of palm waste). The microbial agent prevents Rhizoctonia solani, Phytophthora capsici, Fusarium oxysporum, or Colletotrichum acutatum. A method for preventing powdery mildew includes a step of treating a plant with the microbial agent. Powdery mildew is caused by Leveillula taurica or Erysiphe cichoracearum.

Abstract:
PURPOSE: A medium for culturing fungi with excellent fungi growth ability is provided to cheaply and easily distinguish eco-friendly organic agricultural materials. CONSTITUTION: A medium for culturing fungi contains 2.5% of anhydroglucose, 1.8 weight% of yeast extract, 0.02% of bay salt, agar, and remaining amount of water. The medium is used for testing activity of eco-friendly organic agricultural materials. The fungi are Colletotrichum gloeosporioides.
Abstract:
A Bacillus amyloliquefaciens CC178 strain is provided to control various plant diseases such as gray mold effectively, thereby being used as a biotic pesticide against plant pathogens with no environmental harm. A Bacillus amyloliquefaciens CC178 strain controlling plant pathogens is deposited as a deposition no. KACC 91292P. A plant pathogen controlling agent comprises a fungus body of the strain, a culture solution of the strain or a mixture of the fungus body and the culture solution, wherein the plant pathogen is selected from the group consisting of Botrytis cinerea, Colletotrichum gloeosporioides, Sclerotinia sclerotiorum, Sclerotium cepivorum, Sclerotium sp., Rhizoctonia solani, Didymella bryonia, Alternaria solani, Corynespora cassiicola, Fusarium oxysporum, and Phytophthora capsici. To control the plant pathogen, a plant is treated with the strain or the controlling agent.
