Abstract:
PURPOSE: A controlling method of a phytopathogen is provided to restrain growth of phytopathogen by blue light-irradiating plants. CONSTITUTION: A controlling method of a phytopathogen comprises a step of irradiating a plant with blue light. The blue light is irradiated from an LED source. The blue light has a wavelength of 400nm - 550 nm. The wavelength of the blue light is 460 nm. The phytopathogen is gray mold phytopathogen.
Abstract:
본 발명은 옥수수대 펠렛으로부터 추출한, 오염물질 제거능이 우수한 천연 바이오매스 실리카 나노분말 및 그 제조방법에 관한 것으로, 본 발명에 의할 경우, 무용히 폐기되는 친환경적 농업부산물인 옥수수대를 바이오매스 자원으로 재활용함으로써 광물성 실리카를 대체할 수 있고, pH 조절을 통해 특급실리카인 무정형 실리카를 선택적으로 조제할 수 있으며, 또한, 오염물질 제거능이 우수하고, 특히, 납 등 중금속 흡착능이 매우 뛰어난 효과를 지니고 있다.
Abstract:
PURPOSE: Bacillus subtilis L32 and Saccharomyces cerevisiae L13 isolated from soil are provided to lower salinity in soil, to prevent plant pathogen, to reduce stress and disease in crops, and to enhance crop yield. CONSTITUTION: Bacillus subtilis L32 prevents plant pathogen. Saccharomyces cerevisiae L13 is inoculated to soil and changes insoluble phosphate into soluble phosphate. Bacillus subtilis L32 and Saccharomyces cerevisiae L13 are cultured in a solid medium contains 5 g/L of a yeast extract, 2 g/L of a malt extract, 10 g/L of peptone, 10 g/L of dextrose, 2 g/L of sodium chloride, and 15 g/L of agar in 1000 ml of distilled water.
Abstract:
Provided is a strain bacillus subtilis KKG-1, which has fungicidal activity and tolerances to agricultural chemicals and secures a pesticides decomposition function and an organic matters decomposition function. A strain bacillus subtilis KKG-1 includes antibacterial activity against phytophthora capsici and expresses a 1-aminocyclopropane-1-carboxylate deaminase(ACCD) gene in order to promote crops' growth. Microbial agents or biopesticides for suppressing the phytophthora capsici includes the strain or its culture solution as active ingredients.
