The Effect of Foliar Fertilization with Micronutrients on Disease Severity and Mycotoxin Concentrations in the Grain of Winter Spelt (Triticum aestivum spp. spelta L.): A Case Study

The effect of mineral fertilization (NPK), foliar with micronutrients (Cu, Zn and Mn) the NanoGro biostimulant on severity leaf, spike, stem base root diseases in winter spelt cv. Schwabenkorn was evaluated a field-plot experiment. A mycological analysis performed content Fusarium mycotoxins grain determined. Mineral exerted varied effects Septoria leaf blotch glume blotch, they promoted spread brown rust (excluding NPK + treatment) inhibited black head mold treatment), eyespot foot rot Mn treatment). Fertilization had no influence yield or grain. concentrations deoxynivalenol (DON), nivalenol (NIV), zearalenone (ZEA) fumonisins FB1 FB2 did not exceed maximum permissible levels (except for DON Cu treatments). Throughout experiment, ergosterol (ERG) were highest unfertilized plants.
