“…The population of fungi having an antagonistic effect towards selected fungi pathogenic to cereal was determined according to the method described by Mańka and Mańka (1992). The antagonistic effect of all isolates Trichoderma spp., Clonostachys rosea, and Talaromyces flavus obtained from the soil, was determined in relation to Fusarium avenaceum, F. culmorum, F. equiseti, F. graminearum and Bipolaris sorokiniana strains, whose pathogenicity to cereals has been confirmed in previous studies (Kiecana et al 2014, Cegiełko et al 2019, Mielniczuk 2018.…”

The aim of the research was to determine the quantitative and qualitative composition of soil-borne fungi in the cultivation of oat, as well as to assess the healthiness of this cereal. The experiment considered spring barley and potato as forecrops, and white mustard or lacy phacelia cultivated after spring barley as catch crops before oat. The population of fungi showing antagonistic effect towards selected fungi pathogenic to cereal was determined. The most fungi (pathogenic and antagonistic) were found in the soil under oat cultivation after spring barley, while the least after potato. The cultivation of oat after spring barley with the use of catch crops significantly influenced a reduction in the number of fungi obtained from the soil. On the other hand, catch crop cultivation increased the share of antagonists in the soil fungus population. Among the species recognised as antagonistic, Clonostachys rosea, Trichoderma viride, T. koningii, and T. harzianum predominated. The introduction of catch crops, especially white mustard, also positively influenced the healthiness of oat. The average disease index for the tested oat cultivars grown after potato and after spring barley with white mustard and lacy phacelia as catch crops was 11.02, 12.78 and 15.90, respectively, whereas after spring barley it was 21.75.

“…The low barley productivity in Kazakhstan is to a greater extent caused by the susceptibility of the cultivated varieties to spot blotch [ 7 ]. The pathogen infects barley crops and causes spot blotch, leaf spotting, ordinary stem and root rot, and “black seed,” and, ultimately, significantly reduces grain yield [ 8 , 9 ].…”

In Kazakhstan, barley (Hordeum vulgare L.) is the second most important cereal crop after wheat, with an annual production of approximately 1.9 million tons. The study aimed to characterize Bipolaris sorokiniana isolates obtained from barley fields surveyed. A total of 21 diseased leaves showing spot blotch symptoms were collected from experimental plots located close to the Kazakh Research Institute of Agriculture and Crop Production, where the spring barley Arna cultivar was planted in June 2020. The overall strategy for control of spring barley blotch in the Almaty region of Kazakhstan should include the determination of the aggressiveness of the pathogen isolates to better understand the biology of the diseases and ultimately proper control strategy. Pathogenicity of B. sorokiniana isolates was made on barley seedlings in vitro. Inoculated seedlings showed clear symptoms of B. sorokiniana, and therefore, Koch’s postulates were fulfilled by reisolating the pathogen from artificially inoculated seedlings and identifying it based on standard morphology criteria. Further investigation is needed to understand the impact of B. sorokiniana on barley production in Kazakhstan.

В статье представлены результаты исследований по оценке влияния фактора сорта истепени пораженности пятнистостями листьев на физиологические параметры генофондаярового ячменя, представленного 103 образцами международного питомника ИКАРДА (2ndISBDSN), содержащего сорта и линии - дифференциаторы устойчивости к указанномупатогену. Полевыми исследованиями (2019-2020 гг.) на стационарных опытах отделагенофонда полевых культур и защиты растений Казахского научно-исследовательскогоинститута земледелия и растениеводства в предгорной зоне Юго-востока Казахстанапроведена классификация материала по степени устойчивости к патогену. Выделены триустойчивых к пятнистости листьев сорта ячменя -V Morales, Prikka и Trebi (R-0-10%). Ксравнительно устойчивым к болезни отнесены 5 сортообразцов - Р-20, Р-16,J02006004_09/2T0095, DZ-9-8, ALGERIAN (MR-10-20%).Использованием в НИР нового оборудования - аппарата MultispeQ на платформеPhotosynq.org. установлено, что факторы сорта и уровни развития пятнистости листьевячменя статистически значимо оказывали влияния на индексы фракций хлорофилла -PhiNPQ, NPQt, PhiNO, LEF, фракцию остаточного хлорофилла, уровень температуры листьев(значение P<0,01).
