ABSTRACT

Fortuitous growth of an actinomycete on Fusarium oxysporum f. sp. albedinis culture has shown a host-parasite process. As a response to the actinomycete, the fungus produces thallospores with various forms which can germinate faster than the non-parasited F. o. albedinis microconidies. However, the strains obtained from thallospores showed as sensible as the mother strain towards actinomycete action.
