Изучена чувствительность двух географически отдаленных популяций возбудителя розовой снежной плесени (юга России и Республики Беларусь) к девяти современным фунгицидам. Для исследования отобраны фунгициды, включенные в Государственный каталог пестицидов и агрохимикатов, разрешенных к применению на территории Российской Федерации и рекомендуемые для обработки против снежной плесени. Материалом для изучения служила чистая культура гриба M. nivale. В исследовании использован метод агаровых блоков. Внесение растворов фунгицидов в питательную среду осуществляли двумя стандартными методами – вмешиванием в среду и растиранием препарата по поверхности среды шпателем. Выявлены препараты, обладающие 100%-м фунгицидным действием против обеих изучаемых популяций: Поларис, МЭ, Кинто Дуо, КС и Баритон Супер, КС. Препараты Оплот Трио, ВСК, Вайбранс Трио, ТКС, Максим Форте, КС показали 100%-ю эффективность только против белорусской популяции патогена. Определено, что применение двух методов внесения препарата в питательную среду (вмешивание и растирание по поверхности агара) имеет высокий коэффициент корреляции (для белорусской популяции – rxy= 1,0, для северокавказской – rxy= 0,99). Однако вмешивание меньше ингибирует рост колоний, поэтому является более предпочтительным в исследованиях по изучению чувствительности к препаратам чистой культуры гриба M. nivale. Выявлена статистически достоверная разница между чувствительностью к фунгицидам популяций географически отдаленных регионов (при использовании метода вмешивания Ft 5,32 &lt; Ff 23,2, метода растирания – Ft 5,32 &lt; Ff 37,7). Данные свидетельствуют о гетерогенности возбудителя снежной плесени по чувствительности к современному ассортименту протравителей семян.</p></abstract><trans-abstract xml:lang="en"><p>Pink snow rot (pathogen Microdochium nivale) is the most common low-temperature pathogen worldwide. Sensitivity of two geographically distant populations of the pink snow rot pathogen (southern Russia and the Republic of Belarus) to nine modern fungicides was studied. The fungicides included in the State Catalogue of pesticides and agrochemicals permitted for use in the Russian Federation and recommended for treatment against snow rot were selected for the study. The material for the study was a pure culture of the fungus M. nivale. The agar block method was used in this study. The fungicide solutions were introduced into the nutrient medium using two standard methods: by interfering with the medium and by rubbing the preparation on the medium surface with a spatula. The preparations with 100% fungicidal effect against both studied populations were identified: Polaris, OE, Quinto Duo, SC and Bariton Super, SC. Oplot Trio, WS, Vybrance Trio, FC, Maxim Forte, SC showed 100% efficacy only against the Belarusian population of the pathogen. It was determined that the use of two methods of introducing the preparation into the nutrient medium (intervention and rubbing on the agar surface) has a high correlation coefficient (for the Belarusian population - rxy = 1.0, for the North Caucasian population - rxy = 0.99). However, intervention is less likely to inhibit colony growth and is therefore preferable in drug sensitivity studies of pure culture of the fungus M. nivale. A statistically significant difference was found between the sensitivity to fungicides of populations from geographically distant regions (Ft 5.32 &lt; Ff 23.2 for the intervention method, Ft 5.32 &lt; Ff 37.7 for the rubbing method). The data indicate the heterogeneity of the snow rot pathogen in terms of sensitivity to the modern assortment of seed dressing agents.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>снежная плесень</kwd><kwd>выпревание</kwd><kwd>Microdochium nivale</kwd><kwd>озимые зерновые культуры</kwd></kwd-group><kwd-group xml:lang="en"><kwd>snow rot</kwd><kwd>rotting</kwd><kwd>Microdochium nivale</kwd><kwd>winter cereals</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследования выполнены при поддержке грантов РФФИ № 20-54-00026 Бел_a и БРФФИ № Б20Р-2727.</funding-statement><funding-statement xml:lang="en">The research was supported by RFRF grants No. 20-54-00026 Bel_a and BRRFRF No. B20R-2727</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">Gagkaeva T.Y., Orina A.S., Gavrilova O.P., Gogina N.N.
