PLANT BLIGHT SUPPRESSING AND GROWTH PROMOTING AGENT COMPOSED OF DECOMPOSITION EXTRACTION PRODUCT OF FIBROUS MATERIAL

摘要

PROBLEM TO BE SOLVED: To produce a large amount of a substance having blight suppressing and growth promoting action on plant in high production efficiency by the decomposition and extraction of a fibrous material. SOLUTION: A fibrous material containing lignocellulose component is irradiated with radiation to effect the degradation of the fibrous material and facilitate the extraction of the decomposition product of lignocellulose component existing in the fibrous material. The treated fibrous material is brought into contact with hot water, an organic solvent such as ethanol or their mixture to extract the decomposed product of the lignocellulose component formed in the fibrous material into the solvent and obtain an extract containing the decomposed lignocellulose component. The extract is used as a substance having blight suppressing and growth promoting action on plants.
