Abstract
A use of an inoculum of a geldanamycin-producing strain able to survive in a plant rhizosphere as a biocontrol of common scab affecting the plant and a method for biocontrolling common scab comprising the use of such strain. A biologically pure culture of a Streptomyces strain deposited at the American Type Culture Collection (ATCC) Accession number BAA-668, or a variant thereof.

A method of biocontrolling common scab comprising applying on a plant an effective amount of an inoculum of a geldanamycin-producing strain able to survive in the plant rhizosphere.
A method for modifying the biocontrol efficiency of a bacterial strain comprising intraspecific protoplasm fusion of the bacterial strain with an other strain having a desirable biocontrol property against common scab.
A method for making a biocontrol agent against common scab, which comprises the steps of:
- obtaining a microbial strain susceptible of producing geldanamycin;
- contacting the nucleic acids or the proteins of said strain with a ligand specific to geldanamycin or to a nucleic acid encoding geldanamycin;
- detecting the formation of a complex as an indication of the presence of geldanamycin or of a nucleic acid encoding geldanamycin in said strain,
- whereby said strain or a geldanamycin-producing part of said strain may be used as a biocontrol agent against common scab.
