Abstract
The effect of fungicides on the production of aflatoxin byAspergillus flavus IMI 89717, diacetoxyscirpenol and zearalenone byFusarium graminearum was studied. In a yeast extract - sucrose medium, dicloran, iprodione and vinclozolin fungicides significantly inhibited mycelial growth ofA. flavus at 250 ppm and significantly decreased aflatoxin production at 100, 250 and 500 ppm, respectively. In potato — dextrose broth, these fungicides diminished the mycelial growth ofF. graminearum and production of diacetoxyscirpenol and zearalenone at 100 ppm. Sensitivity of toxigenic mycelia to fungicides increased approximately five-fold in a yeast extract-starch medium with an appreciable reduction in sugar uptake andα-amylase activity.
