| Abstract | ||
| The antimicrobial action of various concentrations of Peganum harmala extracts on growth of four isolates of pathogenic bacteria and toxigenic isolate of Fusarium acuminatum producing T-2 toxin were studied . The results showed that gram positive bacteria ( Staphylococcus aureus and Bacillus subtilis ) were more sensitive to different concentrations ( 125 – 500 mg /Disk) of harmal extracts than gram negative bacteria ( Escherichia coli and pseudomonas fluorescens ) . S. aureus was highly affected than the other bacteria . The results obtained during this study also showed that the harmala extracts were highly active against both of Fusarium acuminatum growth and T-2 toxin at the concentration of harmala which varied from 400 to 600 ppm which showed decreased in mycelial growth from 1.90 to 1.33 ug / 50 ml and from 119.1 to 96.5 ug / ml for T-2 toxin production in liquid medium after 20 days of incubation at 25 C . | ||
