Wheat root diseases can seriously reduce yields and quality of wheat. 1,2,4-Triazole benzoyl arylamine derivatives previously showed good activities against some wheat root fungal pathogens. To further systematically disclose the structure−activity relationship, a series of benzoyl arylamines were designed and prepared. Their structures were characterized and fungicidal activities against Gaeumannomyces graminis var. tritici and Fusarium graminearum were evaluated. The results indicated that the structure of the N-heterocyclic group and the substituted group and their position on the benzamide scaffold had an important influence on the activities, as predicted. Finally, compound 18f was found to show excellent activities against G. graminis var. tritici, F. graminearum, Fusarium culmorum, Fusarium pseudograminearum, and Fusarium moniliforme with half-maximum effective concentrations of 0.002, 0.093, 0.011, 0.881, and 0.287 μg/mL, respectively. These results proposed that compound 18f deserved serious consideration as a novel fungicide candidate for the control of wheat root diseases.

“…Physiological (relative water content, membrane stability index, and chlorophyll content) and non-enzymatic metabolites (soluble sugar, protein, soluble phenol, and flavonoid content) parameters of cereal plants inoculated with B. sorokiniana 191 are changed (Satti et al, 2021;Holz et al, 2022). Leaf sheaths and subroot internodes of barley and winter wheat seedlings can be affected by root rot by 64.7-99.6% (Saad et al, 2021). According to our data, 42-53% of winter wheat plants were healthy, 32-41% were slightly affected by common root rot disease and 10-21% were moderate to severely affected.…”

One of the main drawbacks of winter wheat varieties cultivated in Kazakhstan is their lack of resistance to common root rot. In 2020-2022, samples affected by root rot were taken in the earing phase in stationary experiments of the department of field crops and plant protection of the Kazakh research institute of agriculture and plant growing in the Almaty region. The research aimed to study the harmfulness of common root rot in commercial varieties of winter wheat. The weather did not significantly affect the harmfulness of common root rot. The harmfulness of the disease depended on the variety and degree of disease infestation. These indicators correlated with indicators of plant height, spike length, number of spikelets, and number and weight of grains (p<0.05). All varieties were affected by the disease to a low and moderate degree. In the varieties Almaly and Steklovidnaya 24, yield losses from the disease were 6.4-6.8%; in Farabi, Azharly, and Zhetysu 8.8-9.4%; and in Naz 13.0%. A total of 32-41% of plants were affected by the disease to a low degree and 10-21% to moderate and severe degrees. With a low degree of infestation, yield decreased by 2.4-7.1%, and with moderate and severe degrees by 4.5-12.1%. Factors of the degree of plant infestation and variety correlated (p<0.05) with dependent variables of productive business, stem length, spike length, number of spikelets, and weight of 1,000 grains. Using the method of linear regression, the authors concluded that the winter wheat spikelet number variable was significantly influenced by the variables of stem number (medium correlation) and spikelet length (strong correlation).

“…The disease can manifest itself as browning, yellowing, and mildew in young leaves (Rysbekova and Sultanova, 2022). Saad et al (2021) evaluated the ability of F. pseudograminearum, F. culmorum, F. graminearum, and B. sorokiniana to cause root rot in winter cereals. It was found that barley and soft wheat plants had the highest rates of disease development on leaf sheaths and root internodes (64.7-99.6%), while these indexes were low on oats (5%).…”

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).
