Poland For winter wheat grown in Poland, the accuracy of prediction was very comparable for all four models, ranging amongst 69 (SVML) and 75 (DT) (Table five). On the other hand, greater differences were observed in the capability of the models to predict with accuracy DON levels 200 kg-1 . While the DT-based model had the highest accuracy and also the highest capability to recognise DON levels 200 kg-1 , it performed worst in identifying samples with high DON contamination levels (Table 5).Toxins 2021, 13,13 ofFigure 11.

The other three models showed SN-011 STING rather comparable accuracy. The RF model was better at recognising reduce DON levels, although the SVM models performed improved in recognising DON contamination levels 200 kg-1 (Table five). Amongst by far the most significant variables for the RF-based model were precipitation throughout heading and flowering, and precipitation and Tmean throughout milk development/dough development/ripening (Figures 12 and 13).Toxins 2021, 13,14 ofFigure 12.

Discussion The aim within this study was to create models for the prediction of DON contamination risk in cereal crops, based on the weather circumstances certain for nations within the Baltic Sea area. Field experiments with spring oats, spring barley and spring wheat were conducted throughout 2010014 in 15 counties across Sweden. In Lithuania, field experiments with spring wheat have been performed during 2013018 in seven districts. In Poland, field experiments with winter wheat wer.
