Purpose of this work is to select plant growth regulators and biological preparations of fungicidal action that have a positive effect on the germination energy, germination, growth and development of tomato plants of the Trans Rio variety. The effect of plant growth regulators and microbiological preparations on germination energy, germination, growth and development of plants was determined in laboratory conditions at the base FSBSI FRCBPP by placing treated seeds in a humid chamber. The objects of the study were plant growth regulators: Biodux, F, Obereg, P, Immunocytophyte, TAB; Ribav-Extra, P; biological fungicides based on live cultures of microorganisms: Gamair, SP; Trichoderma Veride 471, SP, Pseudobacterin-2, F, Sporobacterin, SP, as well as strains of B. velezensis BZR 517, B. velezensis BZR 336g. The dye Sapphire Seed Coat, approved for use in the EU in organic farming, was used in the work. The compatibility of biological products was determined by the method of diffusion into agar. The method of diffusion into agar showed that the Sapphire Seed Coat does not have an inhibitory effect on the microbiological preparations Gamair, SP; Trichoderma 471, SP; Pseudobacterin-2, W; Sporobacterin, SP and the strains B. velezensis BZR 517, B. velezensis BZR 336g. A positive effect on the growth and development of tomato preparation Gamair, SP and strain B. velezensis BZR 336g was noted: an increase in root weight by 23.5–52.9% and shoot weight by 36.5–70.3%. There was a statistically significant increase in all biometric indicators when using a mixture of Immunocytophit, TAB and Sapphire Seed Coat: an increase in root weight by 36.4%, length and weight of the shoot by 7.9 and 1.5%, respectively. Biological products have been selected that will be used in the further stages of work as environmentally safe means for processing tomato seeds for long-term storage (Gamair, SP and B. velezensis strain BZR 336g).
