Impact of biofertilizers on resistance to diseases of spring barley

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