“…phaseoli) are highly active and widespread among yellow-pigmented pathogens of legume bacterioses, affecting the aerial parts of plants and seeds. When using pesticides of both chemical and biological origin, these phytopathogens show sensitivity or resistance to them in a wide range of population heterogeneity, which leads to the continuing search for fundamentally new approaches to crop protection technologies ( Varympopi et al, 2022;Oliveira et al, 2023;Halfeld-Vieira et al, 2023). As of 2023, there are no officially registered drugs against phytopathogenic bacteria in Ukraine and the world, which increases the urgency of finding such drugs (Atiq et al, 2022, Taheri et al, 2023.…”

The causative agents of soybean blotch (Pseudomonas savastanoi pv. glycinea) and soybean pustular bacteriosis (Xanthomonas axonopodis pv. glycines) are common phytopathogenic bacteria. However, the lack of officially registered drugs against them stimulates the search for new solutions. The research aims to determine the effect of these micronutrient preparations obtained by electropulse ablation on bacteria during artificial infection of soybean with museum strains of pustular bacteriosis and angular spot pathogens. The antibacterial activity of the studied preparations was compared with the untreated variants and the effect of traditional chemical pesticides based on Fludioxonil and Metalaxyl-M. The spread and development of the disease were assessed by the number of affected plants using a scale from 0 to 4 points. It was found that varietal characteristics of soybeans affect the degree of infection by phytopathogenic bacteria. It was found that weather conditions, in particular air temperature, are a significant factor in the development of disease manifestations. It was proved that seed treatment with a chemical pesticide based on Fludioxonil and Metalaxyl-M in the absence of additional foliar treatment does not reduce the manifestations and degree of damage compared to the control (without treatment). Dressing and foliar treatment with a chemical pesticide based on Fludioxonil and Metalaxyl-M only partially reduce the manifestations of bacteriosis compared to the control variants (by about 15%). At the same time, the use of preparations obtained by electropulse ablation methods is promising against phytopathogenic bacteria in the system of soybean cultivation technology – namely, it was determined that under the condition of soybean plants treatment with experimental preparations according to the Comfort scheme (consumption – 150 ml/t of seeds) + Dobrodiy fertilizer (consumption – 2, 4 l/t of seeds) + microelement preparation “Micro Protect” (consumption of 500 ml/t of seeds) + two foliar treatments with the specified mixture of microelement preparations, the delay in the manifestation of plant damage until the time of harvesting is increased, which in turn is likely to lead to an increase in yields. The practical significance of the work is to determine effective methods of controlling phytopathogenic bacteria that harm soybeans
