Występowanie chorób grzybowych w zasiewach mieszanych i czystych zbóż jarych

The purpose of this research was to determine how mixtures can considerably restrict the development of main fungal diseases. In two vegetation seasons (2009 and 2010) at two locations (Research Station for Variety Testing Kościelna Wieś – Wielkopolska region and Plant Breeding Station Bąków – Opole region) field experiments were conducted with spring cereals pure stands and mixtures and their influence on disease occurrence was evaluated. Powdery mildew (Blumeria graminis f. sp. tritici) reductions from 1.1 to 65.6% (2009) and from 27.27 to 69.58% (2010) were noticed. Obtained results were similar to those presented by other authors.
