Abstract
The paper presents the results of a study on the use of growth regulators against fungal diseases and root rot diseases of soybean under the conditions of Primorsky Territory. The bioproducts were tested on plants of soybean variety Briz. The experiments were performed in meadow-brown clay soil at FSBSI “FSC of Agrobiotechnology of the Far East named after A.K. Chaika”. The small-plot experiment was aimed at evaluating the efficacy of growth regulators Cytodef-100 and Giberelon and biostimulator Biosteam Rost. Treating seeds with Cytodef-100 and Giberelon decreased the progression of Septoria leaf spot by 7,7–7,8%; the biological efficacy was 32,3–32,7%. The efficacy of the growth regulator Cytodef-100 (a complex treatment) reached 45,7% against downy mildew and 41% against Cercospora leaf blight. The biological efficacy of the studied bioproducts against root rot varied within 32,6–43,5% at the emergence stage, 18,5–34,6% at the blooming stage, and 15,4–35,5% at the full pod stage. The highest yield was achieved in the variant with Cytodef-100 (4,8 t/ha). The yield gain was 1,2 t/ha compared to the control (3,6 t/ha).
