Tubaki & Nishih.) in the western Forest-steppe of Ukraine. The best rates of usage for preparations' input according to the studies results during 2021–2022. The fungicide highest efficiency against septoria leaf spot observed in the scope 0.8–1.0 l/ha. The preparation's technical efficiency consisted of 78.8–81.4%. The fungicide BAS 762 02 F usage against alternaria reduced the sunflower's plant disease development on 3.7–6.9 times at preparation's consumption rate 0,6– 1,0 l/ha in comparison with control. The preparation's technical efficiency consisted of 72.7 – 85.5%.
