## 3 Results and Discussion
### Mycotoxin Occurrence
(2015) also reported that cereal grain infection by fungi depends on many factors, including environmental conditions, agricultural practices (e.g., crop production technology) and mostly the level of resistance of the host variety [48]. In our experiment, most of the mentioned practices and conditions were the same for all experimental plots. Hence, it appears that the observed mycotoxin contamination was mainly due to cultivar features. \begin{table} \begin{tabular}{l c c c c c c c c c c} \hline \hline  & **OTA 1** & **FB1 2** & **FB2 3** & **FB1 + FB2** & **ZEA 4** & **HT-2 5** & **T-26** & **HT2 + T2** & **DON 7** & **15-AcDON 8** \\ \hline Maximum levels for mycotoxins in cereal grains 9 & 5.0 & - 10 & - & - & 100.0 & - & - & 200.0 & 1250.0 & - \\
