Abstract: | Propolis ethanolic extract (PEE) at 3 and 4 g/L and ultragriseofulvin (UG) at 0.75 and 1 g/L reduced the percentage of conidia
germination in twoAspergillus flavus isolates. PEE at 1–4 g/L decreased the mycelial dry mass ofA. flavus isolates by 11–80%, and aflatoxin B1 production by 34–100%. UG concentrations of 0.25–1 g/L reduced the growth and aflatoxin B1 production of the isolates by 16–88 and 48–98%, respectively. Any increase in PEE and UG concentration was accompanied by
a clear decrease in the per cent conidia germination, growth and aflatoxin B1 production. At equal concentration, UG was about 4-times more effective than PEE. |
