Abstract

The conducted study has shown that growth regulators have a significant effect on the yield of winter wheat, both when used separately and in combination with fungicides. Processing crops with growth regulators increased the yield of winter wheat from 0.29 to 0.56 t/ha. The introduction of growth regulators in the tillering stage of winter wheat turned out to be more preferable. The yield increase from growth regulators in this phase compared with the phase of output into the tube was 5%. The combined use of growth regulators Silk and Immunocytophyte with the fungicide Colosal Pro significantly reduced the level of malondialdehyde (MDA) in comparison with the control variant. This indicates the anti-stress effect of the drugs, as well as the rapid transition from the beginning of the signal stress stage to the adaptation stage to the stress factor. The use of fungicides had a significant stressful effect on the growth and development of the root system of winter wheat. When using Immunocytophyte, the greatest decrease in the adverse effect of fungicides on winter wheat plants was observed. The combined use of Immunocytophyte with Kolosal Pro increased the daily growth of the roots of the culture by 40% compared with the option where only one fungicide was used.
