Comparative study of the ability of three strains of Fusarium poae for the synthesis of trichothecen mycotoxins has been carried out. Studied strains were isolated from different habitats: forest soil, wheat (plant pathogen) and cranberry root (endophytic strain). All three strains were able to synthesize T-2 toxin, HT-2 toxin and T-2 tetraol but they were in various amounts. The soil strain 50660 was characterized by high level of synthesis of both HT-2 toxin and T-2 tetraol; plant pathogenic 50674 and endophytic 50685 strains were characterized by high level of T-2 tetraol synthesis and lower level of HT-2 toxin synthesis. The main trichothecene mycotoxin of this group - T-2 toxin - was detected in trace amounts for all three strains of F. poae.
