The studies were conducted in 2023-2025 under in vitro conditions and in field trials using the Sadon cultivar. Rhizoctonia disease development and incidence, yield, and tuber size distribution were evaluated. The results obtained confirm the potential of Rondash, ME and Byside, SC as effective crop protection products for controlling Rhizoctonia disease in potato.
