The aim of the research was to identify the effect of new domestic fungicides on seed germination, disease resistance and yield of white lupine. The studies were conducted in 2018-2020 on dark gray forest soil. The object of the research was the agrocenosis of the white lupine variety Dega. The registered area of the experimental plots was 20 m2. The placement of plots is systematic. The experience is repeated three times. Spring wheat was a precursor to lupine. Under the precursor, 2 c/ha of azophoskа were introduced into the soil. Tillage did not differ from the generally accepted one. Sowing was carried out in mid-May in a narrow-row method with row spacing of 7.5 cm. In the experiment, the fungicides Scarlet, 0.4 l/t; Benefit, 0.8 l/t; Palaris, 1.4 l/t were used for pre-sowing seed treatment, and the systemic insecticidal mordant Kruiser, KS - 1 l/t was used for all the options. During the growing season, the first preventive treatment was carried out in the branching phase for all the options with the fungicide Azorro, 1 l/ha, and the second - in the budding phase - the beginning of flowering with the fungicides Benazol, 0.8 kg/ha; Titul Duo, 0.4 l/ha and Triad, 0.6 l/ha. The crops were sprayed in the phase of 3-5 true leaves with the herbicide Pivot at a dose of 0.5 l/ha Against annual and perennial grasses and annual dicotyledonous weeds,. The treatments were carried out with a manual sprayer based on the flow rate of the working solution of 200 l/ha. As a leaf dressing, a complex preparation Ultramag combi was used. It was revealed that on the option Scarlet + Kruiser + Azzoro + Triad +Ultramag combi, the yield increase was 23.5% compared to the control group Scarlet + Kruiser. The biological effectiveness of the protective measures in this option was 85.7%.
