It was found that in the conditions of 2023, the yield of potatoes was in the range from 17.8 to 39.6 t/ha, and the increase, compared to the control, was from 9.9 to 21.8 t/ha, and on average for three years - 20.0 44.0 and 11.4 24.0 t/ha, respectively. The highest yield was provided by the variant (against the background of double sider steam + Bioinsecticide) with combined protection according to the scheme – treatment of tubers – BAR + Organic fertilizer + 3 plant treatments Biofungicide 3 + BAR + Organic fertilizer + Organo-mineral fertilizer, which in 2023 was at the level 39.6 t/ha (difference compared to control – 21.8 t/ha), in 2021-2023 – 44.0 t/ha (difference compared to control – 24.0 t/ha). In the reporting year, all options for protecting potatoes from diseases were effective. It was noted that the level of effectiveness of the preparations Biofungicide 2 and Biofungicide 3 against the background of a double sideral pair + Bioinsecticide, in comparison with Biofungicide 1, was higher. The highest level of effectiveness was noted for combined protection (background + treatment of tubers, + 3 treatments of plants), both for Biofungicide 2 and for Biofungicide 3 - against Alternaria - 73.3 and 75.8%; dry rot – 63.8 and 66.7%; rhizoctoniosis – 72.7 and 74.8%; common scabies – 72.8 and 75.6%. On average, this trend was maintained over three years. Thus, the effectiveness of biofungicides in protecting potatoes was: against Alternaria – 71.6 and 71.9%; dry rot – 82.3 and 84.9%; rhizoctoniosis – 79.4 and 81.8%; common scabies – 76.6 and 79.4%, respectively.
