Abstract: Wheat from two cultivars with contrasting characteristics were harvested in ten experimental plots located in wheat producing areas of the State of Sao Paulo, Brazil. The samples (10 of each cultivar) were analyzed by a gas-chromatographic method for deoxynivalenol (DON), nivalenol (NIV), diacetoxyscirpenol (DAS), toxins T-2 (T-2) and HT-2, T-2 tetraol, T-2 triol, and by a thin-layer chromatographic method for zearalenone (ZEN), aflatoxins B-1, B-2, G(1), G(2), ochratoxin A and sterigmatocystin. No mycotoxins were detected in 13 samples. DON was found in four samples (0.47-0.59 mu g/g), NIV in three samples (0.16-0.40 mu g/g), T-2 in two samples (0.40, 0.80 mu g/g), DAS in one sample (0.60 mu g/g), and ZEN in three samples (0.04-0.21 mu g/g). The wheat samples were also examined for the incidence of fungi. Alternaria, Drechslera, Epicoccum and Cladosporium were the prevailing genera. Among the Fusarium spp., F. semitectum was present in 19 samples and F. moniliforme in 18 samples. No F. graminearum was isolated in the samples.
