Annotation

The field experiments were carried out in accordance with the method of state variety testing, on the areas of 10 m2 in 6-fold repetition. The used agrotechnics was common for spring wheat in the conditions of the Right-bank Forest Steppe of Ukraine. The researchers studied the fungicides Akula EC (prochloraz, 300 g/l + tebuconazole, 140 g/l + cyproconazole, 50 g/l) and Soligor 425 EC (protioconazole, 53 g/l + tebuconazole, 148 g/l + spiroxamine, 224 g/l) on soft and hard spring wheat varieties, i.e. MIP Zlata, Bozhena, MIP Raiduzhna and Diana. The plants were treated at the IV, VIII and X stage of organogenesis. The use of fungicides provided their technical efficiency in the phase of milky ripeness against powdery mildew at the level of 35–71 %, septoria – 31–60 %, brown rust – 65–100 %. A higher efficiency against the diseases was observed in the variant of threefold treatment with Soligor 425 EC (0.6 l/ha) at the IV, VIII and X stages of organogenesis. Application of the fungicides Akula and Soligor 425 EC increased the yield of the varieties by 0.25–0.47 t/ha. The highest yield (3.68–4.23 t/ha) was obtained in the variants with the use of fungicides at the IV, VIII and X stages of organogenesis. On the varieties of MIP Zlata, MIP Raiduzhna and Diana, the highest increase of yield was provided by the fungicide Soligor 425 EC, and on the variety Bozhena – Akula EC. The grown seeds showed the tendency to increase the indices of germination energy and laboratory germination (up to 3 %, SSD05–2.7 %), as compared to the seeds collected from the control variants. Those figures were the highest in variants with triple treatment with fungicides and the indices were 89.5–94.5 % and 91.5–95.5 %, respectively, in control – 86.0–90.0 % and 89.5–92.5 %.
