In Kazakhstan, barley ( 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 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 isolates was made on barley seedlings in vitro. Inoculated seedlings showed clear symptoms of , 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 on barley production in Kazakhstan.
在哈萨克斯坦，大麦（L.）是继小麦之后的第二大重要谷物作物，年产量约为 190 万吨。本研究旨在对从大麦田中调查采集的分离物进行特征描述。共从位于哈萨克斯坦农业和作物生产研究所附近的实验田中采集了 21 片表现出斑点条斑症状的患病叶片，这些叶片是在 2020 年 6 月种植春大麦品种 Arna 的地方采集的。在哈萨克斯坦阿拉木图地区控制春大麦斑点病的总体策略应包括确定病原体分离物的侵袭性，以便更好地了解疾病的生物学特性，并最终制定出适当的控制策略。通过在大麦幼苗上进行离体接种，确定了分离物的致病性。接种的幼苗表现出明显的症状，因此，通过从人工接种的幼苗中重新分离病原体并根据标准形态学标准进行鉴定，满足了科赫假设。需要进一步的研究来了解在哈萨克斯坦对大麦生产的影响。
