Can lichen secondary compounds impact upon the pathogenic soil fungi Fusarium oxysporum and F. avenaceum?

The antifungal activity of secondary lichen metabolites extracted by means acetone and ethanol from Cetraria islandica, Cladonia mitis, C. rangiferina, Pseudevernia furfuracea Usnea dasopoga on the pathogenic fungi Fusarium oxysporum F. avenacuem was examined. compounds tested after their mixture with PDA medium before solidification. most active extracts inhibiting growth fungal mycelia contained fumarprotocetraric, salazinic usnic acids, atranorin. Unparalleled demonstrated an extract mixed islandica P. thalli, which accelerated avenaceum compared control test ethanol. rate two representatives strongly inhibited both alcoholic mitis more than thalli terricolous taxa. A dose 1 ml added to had no significant effect fungi; it indicates usefulness as a solvent for some in this type experiment.
