The paper presents the results of a two-year experiment on fungicide Deposit, muE (1.0 l/t and 1.2 l/t) and its combinations with fungicide Optimo, EC (0.5 l/ha). The experiment was conducted in the south of the Russian Far East in 2021-2022. The first step was a phytophathological inspection of the seeds treated with the fungicide in the laboratory conditions. Deposit was noted to have an antibacterial and antifungal effect. A rhizotron was used for further experimental work to observe the growth and development of soybean plants. It was established that Deposit did not have a negative effect on the crop and facilitated a slight increase in plant weight. The last step of the research was field plot experiments aimed at studying the efficacy of the fungicides against root rot and leaf and stalk diseases of soybean. Deposit was observed to inhibit root rots damaging the crop. At the stage BBCH 62, the fungicide decreased the intensity of infection progression by 11.0% (1.0 l/t) and 15.6% (1.2 l/t). Deposit and Optimo had a high antipathogenic activity against leaf and stalk diseases of soybean. It was established that the fungicides and their combinations were effective against Septoria blight (22.1-35.5%), Cercospora leaf blight (29.7-70.4%), and Ascochyta blight (20.4-58.4%). Additionally, they increased the thousand kernel weight (TKW) and soybean yield.
