ABSTRACT:
Disease in plants caused by infection with cercosporin producing strains ofCercosporamay be controlled by application of laccase. When applied to the locus of the plant, or parts or seed thereof, the cercosporin toxin produced by this pathogen is degraded by the enzyme, thereby preventing or minimizing damage to the plant. The laccase may be applied alone, or in combination with one or more laccase-producing microorganisms.
