✦ Synopsis
In the period of harvest at 1987 field samples of wheat heads with fusariosis symptoms were collected in 18 provinces of Poland. Subsamples of heads infected with Fusarium culmorwn ( W.G.Sm) Sacc. and Fusarium graminearwn Schwabe were analyzed for Fusarium metabolites. In fractions of kernels with visible Fusariumdamage deoxynivalenol (DON) was present in average amount of 18.7 mg/kg (range 9.6-25.3 mg/kg) and 3-acetyl DON 1.9 mg/kg. Fractions of kernels without symptoms of visible Fusurium-damage contained only DON at average 2 mg/kg (range 0.8-3.6 mg/kg). A method of approximate calculation of DON content in a given lot of grain is proposed which may be realized during samples grading.
