The article is devoted to the effect of biofertilizers (Bioklad and Vermix) on the severity of common diseases of spring barley in field trials conducted in the Orel region. The authors estimate risks of spring barley diseases and analyse the results of the three-year experiment, carried out under certain weather and climate conditions. The subject of the research is the spring barley crop Suzdalets under intensive farming (zoned for 2, 3, 5 regions of Russia). For a more comprehensive assessment, the experimental process includes separate and combined application of biofertilizers at two different doses. The results of the experiment shows that spring barley crops have responded to all tested combinations of treatment and, at the same time, biofertilizers Bioklad and Vermix, regardless of the doses of application used, had a positive treatment effect and reduced development of severe plant diseases such as root rot by 8.4%, Helminthosporium spot by 29.2%, powdery mildew by 28.9%, Rhynchosporium by 26.3%, stem rust by 65.9%, Septoria spot by 24.4%, and Fusarium head blight by 12%. The most productive agrocenosis of spring barley was formed with the use of Bioklad: barley yield was 0.59 t/ha at a dose of 1 L/ ha and 0.61 t/ha at a dose of 2 L/ha.
