Abstract
A method is disclosed for preparing an immobilized microorganism-complex having controlling activity against plant pathogenic microorganisms. The method comprises adding an inorganic salt of a polyvalent metal to a liquid containing microorganism cells antagonistic to plant pathogenic microorganisms, drying the resulting microorganism cells so as to obtain a powder, mixing the powdered microorganism cells with particles of humic acid obtained by extraction from compost to obtain aggregates of the microorganism cells, mixing the aggregates with an aqueous carrageenan solution, and then drying the resulting mixture.
