The occurrence of fungal diseases in spring barley, cultivated in cereal crop rotation depending on the intensity of production technologiesWystępowanie chorób na jęczmieniu jarym uprawianym w płodozmianie zbożowym w zależności od stopnia intensywności technologii produkcji

Summary Field experiments were conducted at the Experimental Station Osiny (Institute of Soil Science and Plant Cultivation, Pulawy, Poland) in 2005–2007. Since 1998 spring barley was cultivated in cereal crop rotation under three technologies characterized by different in production intensity. The aim of this study was to determine the occurrence of leaf, stem base and root diseases on spring barley of depending different production intensity (intensive, integrated, economic). The level of production intensity was diversified by plant protection strategy, and did not influence the healthiness of spring barley. The level of infection of spring barley with Gaeumannomyces graminis and the fungal–stem base diseases did not differ between the tested technologies. No leaf infection was recorded in 2005–2006. In the 2007 the percentage of leaf area infected by Pyrenophora teres in all applied technologies was low.
