The influence of multi-component organic fertilizers and biopreparation on the prevalence of root rot and brown leaf rust and crop yield of grain-fallow crop rotation compared with mineral fertilizers and pesticides was studied. Organic technology of cultivation with integrated use of multicomponent organic fertilizers and biolog-ical preparations with functions of biofungicide and biobactericide provided an effective reduction of the inci-dence of field crops affected by root rot and brown leaf rust. The combined use of seed pelleting and bioprepa-ration during the vegetation period reduced the incidence of root rot compared to the control (without fertilizers and preparations) by 49.3 % in winter wheat, 45.8 % in spring durum wheat and 31.0 % in barley. On average by preparations, polyfunctional biopreparations with double treatment during the growing season gave an in-crease in yield of 6.0-8.2 % compared to the pesticide application variants.
