This study was carried out to survey the mycoflora of maize grain stored in the
autumn season in 2011. Special attention to was paid to Fusariumverticillioides and
detection of chemical analysis on the toxins Fumonisin(FUM) and zearalenone
(ZEA) p
roduced from F.verticilloides in three locations for the receipt and storage
of grain in Deirezzor and Raqqa and Hasaka. The results showed that maize kernels
discolored in rate of between 28.9, 32.5 and 36.4% respectively in Hasaka,
Deirezzor and Raqqa. There was a positive coloration between maize kernels
discolored and grain moisture percent. Microbial analysis showed associated fungi
were Penicillium spp. (40.2%), Aspergillus spp. (37.4%), Fusariumspp. (12.6%),
Rhizopus spp. (4.5%), Mucor spp. (3.8%) and Alternaria spp. (1.4%). F.
verticillioides was the most frequency of Fusarium spp. Rates 83.8, 78.9 and 82.0%
respectively in Deirezzor, Raqqa and Hasaka.Toxins (FUM) in Deirezzor was
between 0.6 -5.3 mg / kg, and between 0.9 - 6.7 mg / kg in Raqqa, and from 0.2 to -
2.3 mg / kg in Hasaka, while Toxins (ZEA) were between 0.2-2.1, -0.5 7.6 and
0.03-0.8 mg / kg respectively in the three locations.Chromatographic analysis
showed that the isolation of 42 out of 60 isolates of F. verticillioides was producing
Toxins (FUM), were more isolates producing isolates Raqqa by 80%, in Deirezzor
70% and 60%. In Hasaka.
