In this work the fungi Fusarium oxysporum was evaluated as bioindicator of contamination by a triazine class herbicide, through the screening of the fungal growth. For so, micelial growth measurement was done in culture medium of malt extract and agar in the presence of different concentrations of the herbicide ametrine. The micelial growth measurement was done by the ergosterol content. The ergosterol content was determined by HPLC/DAD, in the wavelength 282 nm, after sample extraction and pre-treatment. The results showed good correlation among fungal biomass and ergosterol content. The fungi growth was reduced by the increase of the ametrine concentration. This shows that using that fungi may be a good alternative for contamination screening.
