Experimental wheat was cultivated after spring cross plants such as spring oilseed rape (Brassica napus ssp. oleiferus Metz.), white mustard (Sinapis alba L), chinese mustard (Brassica juncea L.), oleiferous radish (Raphanus sativus var. oleiferus L.), false flax (Camelina sativa L.), crambe (Crambe abbysinica Hoechst.) and after oats (Avena sativa L.) as a control. The other experimental factor was the method of after-harvest residue management, i.e. ploughing in the stubble, ploughing in the stubble and straw, ploughing in the stubble and straw with nitrogen added. The occurrence of root rot and stem base diseases was affected by weather conditions and forecrop species. Winter wheat roots were attacked to the lowest degree when spring rape and radish were used as forecrops, and to the highest degree - when grown after oat. The culm base was most intensely infected with fusarium foot rot (Fusarium spp.). The remaining root-rot diseases occurred every year but with different intensity. The method of utilization of after-harvest residues did not have a clear effect on the intensity of infection of the roots and culm base of winter wheat
