Abstract:
PURPOSE: A novel strain, Bacillus velezensis B-42 and culture thereof are provided to remove odor and to be used in microbe fertilizer. CONSTITUTION: A multifunctional novel strain with effect of preventing plant diseases and removing odor is Bacillus velezensis B-42(deposit number KACC 91543P). The multifunctional strain is isolated from a mushroom waste medium. A composition for preventing plant diseases contains the strain or culture thereof as an active ingredient. The plant diseases are caused by Sclerotinia sclerotiorum, Rhizoctonia solani, Phytophthora capsici, Pythium ultimum, Cladosporium cucumerinum, Collectotrichum gloeosporioides, or Botrytis cinerea.
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.
