The effect of new biological preparations on economically valuable signs of spring wheat Daria

The article is devoted to the study of the effect of biological preparations in comparison with a chemical fungicide on the economically valuable indicators of spring wheat Daria. The chemical fungicide Alto Super and Oscar, the biological preparation Baksis, 1 l/ha + Rhizoplan, 1 l/ha, multiplicity - 2; Nigor++, 0.1 l/ha, multiplicity - 2; Baksis 1 l/ha + Rhizoplan, 1 l/ha + Nigor++ were studied in the work. It was found that at the 91st stage, the phase of full ripeness of grain. On control plants, the prevalence of diseases was 82%, 26-50% of the plant surface was affected. On plants treated with a chemical fungicide, the prevalence of diseases was 26%, 19% of plants were affected, on plants treated with Bacsis+ Rhizoplan affected 26 - 50 % of the plant surface; on plants treated with Nigor++, the prevalence of diseases was 73% and 26-50% of the plant was affected; on the variant with the combined use of Nigor++, Rhizoplan and Baksis, the prevalence of diseases was 63%, and 26-50% of the plant was affected. The yield of spring wheat grain in the variants was 12.8% with seed moisture, 2.4% grain impurity, 3.4% weed impurity: the control had 54 c/ha (table), and the fungicide variant had a yield increase of 25.4%, when processing Baksis+Rhizoplan increased by 6.5%, when processing Nigor++ - by 2.8%, and with the joint processing of Baksis + Rhizoplan + Nigor++, the yield increase was 7.4%.Under the influence of drugs, the protein and gluten content increases, to a greater extent in the variant with a chemical fungicide and with the combined use of Baksis 1 l / ha + Rhizoplan, 1 l /ha + Nigor ++. All indicators of flour quality have improved
