HOT WATER EXTRACT, PLANT PATHOGENIC MICROBE INHIBITOR AND SOIL MODIFIER

摘要

PROBLEM TO BE SOLVED: To provide a hot water extract capable of inhibiting plant pathogenic microbe as a soil modifier.;SOLUTION: The hot water extract is a hot water extract of biomass and has mass percentage of acetic acid to total mass of acid contained of 5 to 50%. Percentage of glucose in contained saccharide is 7.0 mass% or less. Absorbance at wavelength of 420 nm is 0.05 or more when saccharide concentration of contained saccharide is 1 mass%. It has proliferation inhibition effect on plant pathogenic microbe. The plant pathogenic microbe is microorganism belonging to Fusarium.;SELECTED DRAWING: None;COPYRIGHT: (C)2018,JPO&INPIT
