Winter wheat cv. Zyta was grown in organic and integrated farming systems as part of a field experiment conducted in north-eastern Poland in 2008-2010. The aim of the study was the assessment of the effect of different farming systems and various protective treatments on plant health status. The severity of infections caused by Septoria spp., Blumeria graminis and Puccinia recondite, affecting the leaves of winter wheat plants, was determined mainly by weather conditions and the applied cultivation system. 2009 was a rainy year which supported the development of Septoria diseases, whereas the dry year 2010 was favourable for the growth of powdery mildew of grasses and cereals. The leaves of winter wheat plants grown in the organic farming system were more often infected with brown rust, whereas plants grown in two variants of the integrated farming system were more likely to be affected by Septoria diseases and powdery mildew. The severity of stem-base diseases varied depending on the year of the study and the applied forecrop. The highest infection rates were reported when winter wheat was grown as a forecrop. The rainy year 2009 stimulated the development of stem-base diseases. The positive effect of EM biopreparation on the health status of winter wheat was observed only in the organic farming system.

W latach 2008-2010 w północno-wschodniej Polsce uprawiano pszenicę ozimą odmiany Zyta w systemie ekologicznym i integrowanym. Celem badań była ocena wpływu płodozmianów, agrotechniki i zabiegów ochronnych na zdrowotność roślin. Nasilenie infekcji liści pszenicy ozimej wywołanych przez Septoria spp., Blumeria graminis i Puccinia recondite uzależnione było od warunków atmosferycznych i zastosowanego systemu uprawy. Rok 2009 był deszczowy, co sprzyjało rozwojowi septoriozy, natomiast suchy 2010 rok sprzyjał rozwojowi mączniaka prawdziwego zbóż i traw. Liście pszenicy ozimej uprawianej w systemach ekologicznych częściej wykazywały objawy rdzy brunatnej, w dwóch wariantach systemu integrowanego były bardziej narażone na infekcje patogenami powodującymi septoriozy i mączniaka prawdziwego. Nasilenie chorób podstawy źdźbła było zróżnicowane w latach badań i uzależnione od przedplonu. Najwyższe wskaźniki zachorowalności odnotowano w przypadku, gdy pszenicę ozimą uprawiano po pszenicy. Deszczowy rok 2009 przyczynił się do rozwoju chorób podstawy źdźbła. Pozytywny wpływ biopreparatu EM na zdrowotność pszenicy ozimej stwierdzono tylko w systemach uprawy ekologicznej.
