The article presents the results of studies on the development of stone smut (Ustilago hordei Kell. et Sw.) in winter barley crops in the conditions of the Western Forest-Steppe of Ukraine during 2024–2025. It was established that this disease occupied a leading place among crop diseases and influenced the formation of yield. It was shown that the intensity of the development of ear disease was largely determined by meteorological conditions, in particular the amount and frequency of precipitation in the flowering–milk ripeness phase of the grain, which contributed to the intensification of the infectious process and the accumulation of the infectious background.
The effectiveness of pre-sowing seed treatment with Kinto Duo, hp (2.5 l/t) and Insur Perform, hp (0.5 l/t) was studied. It was established that the use of pesticides provided reliable control of the development of stone soot in the early stages of organogenesis and contributed to the formation of productive crops throughout the growing season. The highest biological and economic efficiency was obtained when using the drug Insur Perform, hp (0.5 l / t), which, due to its pronounced systemic action, provided the maximum reduction in the development of the disease during the grain filling period and the highest increase in yield.
The yield in the control variant was 3.7 t / ha, while the use of Kinto Duo provided its increase by 0.3 t / ha, and Insur Perform - by 0.5 t / ha. The economic assessment confirmed the feasibility of using pesticides, since the conditional net income increased by 2.3–4.33 thousand UAH / ha, and the level of profitability – up to 82.9%. The results obtained demonstrate the effectiveness of combining varietal characteristics with a scientifically based choice of fungicide for the full realization of the productive potential of winter barley in specific agroclimatic conditions
