“…The fungus B. sorokiniana has a wide geographical distribution area (Guest, 2017;McDonald et al, 2018;Özer et al, 2020). The low yield of barley in Kazakhstan is largely due to the susceptibility of the cultivated varieties to leaf spotting, while the yield and productivity of plants are significantly reduced by 30-40% (Cegiełko et al, 2018(Cegiełko et al, , 2019Haas et al, 2018;Pathak et al, 2020). Barley strips are covered with dark spots with a brown or dark gray coating, photosynthesis is disrupted, the growth and development of plants slow down and they form fewer primary and secondary roots.…”

Spring barley is an important high-value crop globally.However, it is highly susceptible to soil-borne diseases in Kazakhstan and the world. Bipolaris sorokiniana (Sacc.) Shoemaker is the most important soil-borne pathogen that causes root rot and spot blotch diseases in cereal crops. This study aimed to evaluate the ability of B. sorokiniana isolated from spring barley leaves to survive in plant residuals of different crops. The fungus was isolated from spring barley leaves from the Zholbarys agro farm of Kerbylak district of Almaty, southeastern Kazakhstan, in 2021. Laboratory experiments were conducted at Kazakh National Agrarian Research University. The study was conducted on 10 th days of seedlings of cereal, legume, and oilseed crops. The obtained results showed that seedlings of spring barley, spring wheat, and oats retained the B. sorokiniana infection. Interestingly, the infection of B. sorokiniana isolated from leaves of spring barley statistically significantly increased symptoms of spot blotch on spring wheat and spring barley seedlings, while symptoms decreased on oats (P-value <0.01). The introduction of rapeseed, chickpeas, peas, and oats into the crop rotation system in southeastern Kazakhstan could limit the volume of the B. sorokiniana infection in spring wheat and spring barley. On rapeseed, peas, and chickpeas seedlings no symptoms of spot blotch were observed (P-value <0.01).

“…e low barley productivity in Kazakhstan is to a greater extent caused by the susceptibility of the cultivated varieties to spot blotch [7]. e pathogen infects barley crops and causes spot blotch, leaf spotting, ordinary stem and root rot, and "black seed," and, ultimately, signi cantly reduces grain yield [8,9]. Symptoms of B. sorokiniana in cereal rots include chlorosis and necrosis of cotyledons, water-soaked lesions on the crown and lower stem, stunting, preemergence and postemergence damping-o , wilting, and brown to black rot in the lower taproot and lateral roots with decay in the cortical region, and discoloration [10].…”

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.
