“…The effectiveness of the use of biologies based on bacterial and fungal preparations depends on their competitiveness in relation to pathogenic microflora and increased resistance to environmental conditions [2]. One of the current trends is an increase in the use of biologies for seed treatment and spraying of crops during the growing season [3].…”

The analysis of the effect of the applied biologies and chemical protectant in seed treatment carried out using paper rolls showed germination against the background of chemical dressing + bacteria – 85-96% at the control of 88%, against the background of pure bacteria 81-88% decrease by 2-10% from the background with chemical dressing. The root length was 11-13 cm, the root mass significantly exceeded the control on the variants of mixtures of chemical dressing and biopreparation. The length of the coleoptile significantly decreased by 1.6-2.6 cm according to the chemical dressing options, the sprout length varied between 9.6-12.0 cm, and a decrease in the sprout length was observed in most variants with a chemical protectant. Against the background of pure chemical protection (seed dressing), the protection efficiency was 100% during the tillering phase and 86% by the end of the growing season of the crop against root rot, mixed versions of the protectant with bacteria reduced faster the protection level. As a result, experimental data were obtained for testing mixtures of bacterial strains of R. Bacillus in the system of pre-sowing dressing of spring wheat seeds, with a positive effect on yield, strains of biological products were isolated (szr + 875 x 9-08; szr + 875 x Mm8; szr + 9-08 x Mm8).

In 2018–2019, the studies were carried out in order to assess the effectiveness of the use of various biofungicides on spring bread wheat (Triticum aestivum L.) on grey wood soil in the Predkamsk zone of the Republic of Tatarstan. The agents based on Bacillus subtilis strain 63-Z (Baxis®) and Pseudomonas aureofaciens strain (Pseudobacterin 2®) were used as biofungicides. The chemical fungicides were used as a standard (for seed treatment – prothioconazole + tebuconazole (Lamador®); for spraying – spiroxamine + tebuconazole + triadimenol (Falcon®)). The research results showed that the use of biofungicides for seed treatment and spraying during the earing phase of wheat has a pronounced effect on the length of the stem and the number of grains in the ear. Under the influence of the use of biofungicides, the damage to plants by root rot, leaf septoria and powdery mildew was reduced. In terms of their effect on leaf septoria and powdery mildew, the chemical fungicides were somewhat superior to biological ones. The highest yield of spring soft wheat was obtained using the scheme in which the seeds were treated with Baxis and the plants in the earing phase were sprayed with Pseudobacterin 2. This scheme provided the increase in yield by 1.1 t / ha compared to control and by 0.29 t / ha when using standard chemical fungicides for seed treatment and spraying of crops. The use of such a scheme significantly reduces the cost of the protection of wheat plants from diseases. As a result of research, it was shown that with a weak and medium development of diseases, the use of biofungicides can be an effective alternative to the use of standard chemical fungicides.
