Native Biocrust Cyanobacteria Strains Showing Antagonism against Three Soilborne Pathogenic Fungi.

The biocontrol potential of three native soil cyanobacteria from biological soil crusts (, , and ) was tested by means of in vitro mycelial growth inhibition assays for eighteen cyanobacteria-based products against three phytopathogenic soilborne fungi (, , and f. sp. ).
