Objective. To study the effectiveness of winter wheat seed treatment with chemical disinfectants and a complex preparation based on Azotobacter vinelandii 7 AI, A. chroococcum 8 AI and Bacillus megaterium 39 AI. Methods. The microorganisms that form the basis of the complex biological product were tested for compatibility with fungicides in the laboratory. For this purpose, the bacteria were incubated with a chemical disinfectant and their titer was subsequently determined. The effectiveness of the microbial preparation alone and in combination with chemical fungicides was tested in the fields of the Skvyra Experimental Station of Organic Production of the Institute of Agroecology and Environmental Management of the National Academy of Agrarian Sciences. All records, observations of the growth and development of plants in crops, morphological parameters and analyses in the experiment were carried out in accordance with generally accepted methods. Results. While testing the compatibility of microorganisms with agrochemicals, it was found that the fungicide Weibrans Trio (sedaxane 25 g/l, fludioxonil 25 g/l, tebuconazole 10 g/l) provided a slight decrease in the number of bacteria tested (up to 10 %). The fungicide Avicenna (tebuconazole 50 g/l, prochloraz 250 g/l, cresoxim-methyl 50 g/l) led to a critical reduction in the titer of bacteria, especially representatives of the genus Azotobacter. The fungicide Acanto Plus (picoxystrobin 200 g/l, ciproconazole 80 g/l) had a slight effect on the number of bacteria studied over time. The complex treatment of winter wheat seeds, even in the mixture of the microbial preparation with Weibrans Trio and Acanto Plus fungicides, respectively, had a positive effect on the growth and development of wheat plants, increasing the yield of the crop. Conclusions. The results obtained indicate the effectiveness of the use of a new complex microbial preparation in the cultivation of winter wheat. The negative effect of the fungicide Avicenna on the components of the biological product when used in the same tank mixture for seed treatment was established. The combined use of the microbial preparation with the fungicides Weibrans Trio and Acanto Plus in the technology of winter wheat cultivation is acceptable.
