Abstract:
An agent for inducing resistance against phytopathogenic microorganisms in plants wherein the agent is an extract of a biomass, said biomass being derived from a biotechnological fermentation process, from non-plant-pathogenic microorganisms, not including microorganisms of the Saccharomyces genus, wherein said fermentation process results in a wet biomass phase and a liquid phase, said wet biomass is separated from said liquid phase by filtration and dried for at least 4 hours at a temperature of at least 130.degree. C. to give a dried biomass, said agent obtainable from said dried biomass by the following process:a) resuspending 50 g to 200 g (dry weight) of said dried biomass per liter of inorganic or organic solvent to yield a suspension;b) stirring said suspension at room temperature for 1 to 12 hours;c) incubating said suspension;d) resuspending the result of step c;e) allowing the result of step d to cool to room temperature; andf) optionally filtering the result of step e.
