Для предотвращения потерь урожая необходим регулярный мониторинг болезни в посевах, позволяющий своевременно применять средства защиты растений. Выявление болезни на начальной стадии возможно при раннем обнаружении возбудителя. Установлено, что спороулавливающие устройства позволяют выявлять возбудителей инфекций при развитии болезней менее 1%, когда мониторинг классическими методами менее эффективен. Цель данных исследований – изучить динамику лета конидий B. graminis в условиях центральной зоны Краснодарского края и выявить корреляцию между заспоренностью воздуха и развитием мучнистой росы в посевах озимой пшеницы, что позволит оценить эффективность использования спороулавливателей для мониторинга и прогнозирования развития этого заболевания. Исследования проводились на базе ФГБНУ ФНЦБЗР в 2022–2024 гг. Для исследований были выбраны следующие сорта озимой пшеницы: Гром, Безостая 100, Юка, Алексеич и Сварог. Отбор конидий осуществлялся флюгерной спороловушкой и устройством для определения заспоренности растений. Параллельно были проведены учеты развития мучнистой росы по классической фитопатологической методике. Изучена динамика лета конидий B. graminis в условиях Центральной зоны Краснодарского края: начало лета конидий начинается с момента весеннего возобновления вегетации пшеницы, пик лета приходится на фазу вегетации «Выход в трубку», а с появлением флагового листа количество конидий в воздухе постепенно снижается. Выявлена корреляция между заспоренностью воздуха и развитием мучнистой росы в исследуемых посевах.</p></abstract><trans-abstract xml:lang="en"><p>Wheat powdery mildew, caused by Blumeria graminis f. sp. tritici, is a widespread disease capable of causing yield losses of up to 100% under high infection pressure. To prevent such losses, regular monitoring of crops is essential to ensure the timely application of plant protection products. Identifying the disease at its initial stage is possible through the early detection of the pathogen. It has been established that spore-trapping devices can detect pathogens when disease development rate is still below 1%, when classical monitoring methods are less effective. This study aimed to investigate the dynamics of B. graminis conidial flight in the Central zone of the Krasnodar Territory and to identify the correlation between airborne spore concentration and powdery mildew development in winter wheat crops. This evaluation assesses the effectiveness of spore traps for monitoring and forecasting the disease. The research was conducted at the Federal Scientific Center for Biological Plant Protection (FRCBPP) in 2022–2024. The following winter wheat varieties were selected for the study: Grom, Bezostaya 100, Yuka, Alekseich, and Svarog. Conidia sampling was performed using a vane-type spore trap and a plant spore load assessment device. Simultaneously, powdery mildew development was recorded using classical phytopathological methods. The study characterized the dynamics of B. graminis conidial flight in the Central zone of the Krasnodar Territory: dispersal begins with the spring resumption of wheat vegetation, peaks during the stem elongation stage, and gradually decreases after the emergence of the flag leaf. A significant correlation was found between airborne spore concentration and the development of powdery mildew in the investigated crops.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>фитосанитарный мониторинг</kwd><kwd>пшеница озимая</kwd><kwd>мучнистая роса</kwd><kwd>конидии</kwd><kwd>споры</kwd><kwd>спороулавливатель</kwd></kwd-group><kwd-group xml:lang="en"><kwd>phytosanitary monitoring</kwd><kwd>winter wheat</kwd><kwd>powdery mildew</kwd><kwd>conidia</kwd><kwd>spores</kwd><kwd>spore trap</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено за счет гранта Российского научного фонда № 25–26–00273; https://rscf.ru/project/25–26–00273/</funding-statement><funding-statement xml:lang="en">The research was funded by the Russian Science Foundation, grant No. 25–26–00273, https://rscf.ru/en/project/25–26–00273/</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Dean R., Van Kan J.A.L., Pretorius Z.A., Hammond-Kosack K.E. et al.
