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).</p></abstract><trans-abstract xml:lang="ru"><p>Представлены результаты исследований по применению регуляторов роста против грибных болезней на сое в условиях Приморского края. Изучение препаратов производили на растениях сои сорта Бриз. Опыты закладывали на лугово-бурой тяжелосуглинистой почве в ФГБНУ «ФНЦ агробиотехнологий Дальнего Востока им. А.К. Чайки». В полевом мелкоделяночном опыте проведена оценка эффективности регуляторов роста Цитодеф-100 и Гиберелон, биостимулятора Биостим Рост. Обработка семян и растений препаратами Цитодеф-100 и Гиберелон способствовала снижению проявлений септориоза на 7,7–7,8%, а биологическая эффективность составила 32,3–32,7%. Регулятор роста Цитодеф-100 (комплексная обработка) обеспечил эффективность против пероноспороза на 45,7% и церкоспороза на 41%. Биологическая эффективность против корневой гнили в вариантах опыта при использовании препаратов составила 32,6–43,5% в фазе полных всходов, 18,5–34,6% – в фазе цветения и 15,4–35,5% – в фазе налива бобов. Высокие показатели урожайности были достигнуты в варианте с применением регулятора роста Цитодеф-100 (4,8 т/га), по сравнению с контролем (3,6 т/га), прибавка составила 1,2 т/га.</p></trans-abstract><kwd-group xml:lang="en"><kwd>soybean</kwd><kwd>growth regulators</kwd><kwd>fungal diseases</kwd><kwd>efficacy</kwd><kwd>productivity</kwd><kwd>yield</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>соя</kwd><kwd>регуляторы роста</kwd><kwd>грибные болезни</kwd><kwd>эффективность</kwd><kwd>продуктивность</kwd><kwd>урожайность</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Проведение работы и публикация статьи осуществлены на личные средства авторского коллектива</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Rizzo G., Baroni L.
