The formation of grain yield and reduction of infestation of spring wheat root rots in the use of biologics

The article presents the results of studies on the influence of growth microfertilizer and fungicides on the development of diseases and productivity of spring wheat in the conditions of the Kurgan region. Currently, the identification of new strains of microorganisms that are able to suppress the development of pathogenic microflora, which ultimately reduces the incidence of plants, increases productivity, improves the quality of the crop production and allows to reduce use of fungicides on crops. In our research seed treatment with biological preparations helped to reduce the development of root rot. Biological preparations acting on the basis of the antagonism of microorganisms, reduce the damage of wheat by 3.6% relative to the control,biological efficiency was 52.5%. Seed treatment gumimaksom 0.5 l/t reduced development of root rot by 2.5% relative to the control. This option was ineffective in combating the disease (35.2%). The maximum increase was noted when using fitosporin-M, where she was 2.4-2.8 t/ha. As a result of years of research conducted in the Kurgan Agricultural Research Institute for the Study of a wide range of biological products found that their environmentally appropriate to apply to spring wheat in order to protect from external infection (root rot), and to provide a stimulating effect on plants by increasing vigor and improving the quality of the grain. In all the studied variants produced a significant increase in the productivity of spring wheat.
