The aim of this study was to isolate bacteria from silage based on corn or alfalfa and haylage, which are a rich source of lactic acid bacteria. During the experiments fungistatic properties against some pathogenic fungi belonging to Fusarium genus were evaluated. The present study examined 46 isolates from silage and haylage. Most of the lactic acid bacteria isolates reveal fungistatic activity against eight tested indicator strains. Results depended in a large extent on the species and strain of the fungus.
