Abstract As a result, it was established that the greatest reduction in the development of root rot was noted in the variant with Hetomik. Thus, in the phase of entering the tube, the rate of development of the disease decreased by 2.4 times compared to the control and amounted to 5.3 % during the three years of research. The same trend persisted in other phases of crop development, namely flowering and waxy grain maturity, where the level of root rot development was 8.2 % and 27.3 %. Seed treatment with Azotobacterin-K and Ecophosphorin also had a positive effect on limiting the development of root rot. However, the lowest level of disease development was observed in the tube emergence phase – 10.4 % and 8.5 %, respectively, after seed treatment with Ecophosphorin and Azotobacterin-K. The development of powdery mildew on average over the three years of research in the control variant was 12.6 %, and when treating seeds with microbial preparations it varied from 1.6 % (after application of Hetomik) to 3.4 % (Azotobacterin-K) and 3.7 % (treatments with Ecophosphorin). During seed treatment with Hetomik, the development of brown leaf rust was 2.1 % and was the lowest compared to other options (Ekophosphorin – 3.9 %; Azotobacterin-K – 3.6 %) for 5.2 % – in the control. The maximum development of septoriosis of the leaves was observed in the control variant (7.9 %), but it decreased to 5.3–6.6 % when the seeds were treated with microbial preparations. When treated with the drug Hetomik, the yield increase on average over the years of research was 23.8 % compared to the control.The use of Azotobacterin-K also helped to increase the yield of this crop in all years of research by an average of 20.5 %. A slightly lower yield of winter triticale was noted for the use of Ecophosphorin, where the increase compared to the control was 18.7 %, compared to the previous options. The obtained results of the research indicate the promising application of microbial preparations in winter triticale cultivation technologies – Hetomik, Azotobacterin-K and Ecophosphorin, which can be used to limit the development of root rots to 5.3–27.3 %, leaf diseases – 1.6–5, 3 % for an increase in productivity by 18.7–23.8 %.
