Fusarium and Aspergillus toxigenic species are considered to be the most common pathogens
in maize. Agroecological conditions in Serbia favour the development of numerous pathogenic
and toxigenic species of the genus Fusarium and Aspergillus. Global climate change may
favour the contamination of maize with high levels of aflatoxins and fusariotoxins in temperate
areas, such as Serbia. Fusarium graminearum synthesises mycotoxins from which the most
important are type B trichothecene - deoxynivalenol (DON), its acetyl-ester derivatives (3-
АDON and 15-АDON) and nivalenol (NIV). The two most important species of fungi
responsible for aspergillosis kernel and ear rot are Aspergillus flavus and Aspergillus
parasiticus, producers of aflatoxins (B1, B2, G1, and G2).
Isolates of F. graminearum and A. parasiticus identified from maize grain samples collected
over 12 years from 40 localities in Serbia were analyzed. Production potential of isolates were
determined by high-pe...rformance liquid chromatography method (HPLC).
Results of perennial research showed high variability in the concentrations of mycotoxins
deoxynivalenol and aflatoxins in maize kernels. Detected concentrations of DON varied from
10,9 to 154.6 µg/g (average 47,2 µg/g), while 3ADON concentrations ranged from 3.42 to 71.6
µg/g (average 15,6 µg/g ) and 15ADON from 5.4 to 121.3 µg/g (average 29,8 µg/g). Mycotoxin
15ADON were predominant in observed samples. The average synthesis of aflatoxin B1 was
4145.97 µg/kg (range 14.24 to 7361.03 µg/kg) by which the isolates of this group were
classified into strong producers of AFB1. The average synthesis of aflatoxin B2 was 403.55
µg/kg, aflatoxin G1 3490.07 µg/kg and G2 198.29 µg/kg averaging, respectivel
