Ten of 19 (53%) tested isolates of Fusarium acuminatum , from different geographical origins and sources, showed in vitro antagonistic activity (inhibition at distance) to mycelial growth of F. moniliforme. Moreover, when F. acuminatum ITEM‐728 was tested against 25 different fungal species, an initial inhibition at a distance was observed which was followed by the spread of the F. acuminatum mycelium over the opposite fungal colony to various degrees. Most of the F. acuminatum isolates which showed antagonistic activity proved to be enniatin B (EB) producers, and some of them also formed moniliformin (MF). The toxic activity of the methanol extract of F. acuminatum ITEM‐728 towards some test microorganisms was closely related to the EB concentration. In particular, Bacillus subtilis proved to be a very sensitive test microorganism.
