Summary Fields experiments were conducted in two growing seasons. The aim of studies was to evaluate the efficacy of different fungicides used separately and as a mixture with or without addition of adjuvants against leaf and ear diseases in winter wheat. The obtained results related significant differences in the efficacy of tested fungicides. The application of fungicide mixtures at lower doses, jointly with adjuvants resulted in their higher efficacy and longer action as compared to the treatments without adjuvants.
