To analyze the data in the available literature regarding the effect of various tillages on the development and prevalence of wheat pathogens.Discussion. According to the literature, the existing tillage technologies – classical, minimal and zero – significantly affect the development of pathogens that cause the development of wheat diseases in regions that differ in soil and climatic conditions. In Russia and other countries near and far, the issue of combating diseases of agricultural crops is dealt with by chemical, biological and agrotechnical methods. Despite the fact that agrotechnical methods are of the utmost importance in the general system of measures to protect plants from damage, for a long‐time agricultural technology as a means of plant protection was underestimated. However, many agricultural techniques, as well as genetics and selection, increase the resistance of plants to damage.Conclusion. As a result of these techniques, it is possible to create environmental conditions that will be unfavourable for the reproduction of diseases. At the present time, opinion is firmly established that separately undertaken, isolated methods cannot properly solve the problem of protecting plants from pathogens of agricultural crops. Only a set of methods combined into a system of measures provides a solid basis for plant protection. And in this system of measures, the role of agricultural practices is extremely large.","PeriodicalId":41300,"journal":{"name":"South of Russia-Ecology Development","volume":"36 1","pages":""},"PeriodicalIF":0.2,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85058777","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To study the structure of bacteria exometabolites of the Bacillus velezensis BZR336g strain using the GC×GC‐MS method when cultivated on nutrient media differing in the content of microelements.Material and Methods. The object of the study is the B. velezensis BZR336g bacterium strain. It shows promise for the development of a biopreparation on its basis for protecting plants against phytopathogenic fungi. Exometabolites were isolated from the liquid culture and their metabolomic profile was analysed with the GC×GC‐MS method using a LECO Pegasus BT‐4D device.Results. Among the identified compounds one can see the precursors of biologically active metabolites of bacteria of the strain B. velezensis BZR336g. Analysis of the total accumulation of fatty acids and their analogs, as well as of amino acids and peptides, by B. velezensis BZR336g bacteria on nutrient media differing in the content of metal ions, shows that Co2+ ions in combination with Mn2+ and Zn2+ ions play an important role in inducing their synthesis. The presence of the Co2+ ion in the nutrient medium has the greatest influence on the synthesis of peptide components. If it is removed from the nutrient medium, the amount of amino acids and peptides decreases by almost two times. Benzene compounds can act as precursors of aromatic hydrocarbons, which are also of interest in the analysis of bacterial metabolism, since they have antimicrobial activity.Conclusions. The number of compounds that are precursors of lipopeptide metabolites depends on the content of metal ions in the nutrient medium. This fact may vary depending on the combination in which the metals are present.","PeriodicalId":41300,"journal":{"name":"South of Russia-Ecology Development","volume":"49 1","pages":""},"PeriodicalIF":0.2,"publicationDate":"2022-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84833856","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To study the variability of the intrapopulation structure of the causative agent of wheat leaf rust (Puccinia triticina Erikss.) on the basis of pathogenicity under the influence of the combined fungicide Abacus Ultra, SE.Material and Methods. The studies were carried out in the greenhouse complex of the Federal Research Center of Biological Plant Protection on the winter wheat variety Krasnodarskaya 99 which is susceptible to leaf rust. The material studied was the combined fungicide Abacus Ultra, SE with application rates of 0.75; 1.0; 1.25; 1.5; 1.75 l/ha. The work was carried out according to generally accepted methods.Results. The influence of the impact of different rates of application of the fungicide Abacus Ultra, SE on the average virulence of the P. triticina population was established, this indicator varying from 40.0% (control [without treatment]) to 19.5% (fungicide application rate 1.75 l/ha). As a result of the analysis of the phenotypic composition of the population, 5 phenotypes were identified. A decrease in the viability of spores of the fungus P. triticina with an increase in the rate of application of the fungicide was established, this indicator varying from 69.1% (0.75 l/ha) to 29.2% (1.75 l/ha). A decrease in the aggressiveness of the population of the causative agent of leaf rust with an increase in the rate of application of the drug was established. The biological effectiveness of the fungicide Abacus Ultra, SE against the pathogen was 95.3–97.8% at the recommended application rate of 1.0–1.5 l/ha.Conclusion. The study showed that the population of the leaf rust pathogen treated with the chemical fungicide Abacus Ultra, SE is characterised by a change in structure in terms of aggressiveness and virulence, while the sensitivity remains high due to the combination of the active substances pyraclostrobin and epoxiconazole with a different mechanism of action in the preparation.","PeriodicalId":41300,"journal":{"name":"South of Russia-Ecology Development","volume":"5 1","pages":""},"PeriodicalIF":0.2,"publicationDate":"2022-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86939867","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Control plots located in different landscape provinces of the Volga‐Oka interfluve were compared in terms of the state of the vegetation cover, as well as the type of overgrowth.Results. Three types of overgrowing of postagrogenic lands characteristic of the initial and intermediate stages of overgrowing of pre‐climax communities have been identified: overgrowing of fields associated with a change in land use; overgrowing of fields with a nearby forest; and overgrowing of fields without a closely located forest.Conclusion. It was shown that as a result of the overgrowing of agricultural lands, the species diversity of plant communities is sharply reduced, the restoration of which is very problematic in the foreseeable future. While postagrogenic phytocenoses are able to gradually restore their production potential to the level of natural phytocenoses, however, their productivity will occur with a different species composition of herbaceous plants with low biodiversity.","PeriodicalId":41300,"journal":{"name":"South of Russia-Ecology Development","volume":"1 1","pages":""},"PeriodicalIF":0.2,"publicationDate":"2022-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90935448","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To systematise data on pathogens of viral diseases of garden and berry crops in the south of the Russian Far East.Discussion. The peculiar climatic features of the Far East limit the range of garden and berry crops. However, there are a significant number of species of wild fruits and berry plants in the region, which have increased (often – record breaking) frost resistance and are therefore actively used for breeding new cultural forms. At the same time, for the last century and a half new varieties of garden crops have been actively introduced to the Far East, which has lead to an increase in the risk of penetration of entire phytovirus complexes together with vegetatively propagated (cuttings, vaccinations) plants. The greatest damage to garden crops in the Far East is caused by a number of representatives of the genus Nepovirus (Picornavirales: Secoviridae): Tomato ringspot virus, Arabis mosaic virus, Raspberry ringspot virus, Grapevine fanleaf virus, Grapevine linear pattern virus as well as several still unidentified viruses. Among other taxonomic groups of phytoviruses dangerous for fruit and berry crops one could point out Potato virus Y (Patatavirales: Potyviridae, Potyvirus), Carnation ringspot virus (Tolivirales: Tombusviridae, Dianthovirus), Clover yellow mosaic virus (Tymovirales: Alphaflexiviridae, Potexvirus), Cucumber mosaic virus (Martellivirales: Bromoviridae, Cucumovirus), Alfalfa mosaic virus (Martellivirales: Bromoviridae, Alfamovirus). The paper considers the species composition of aphids‐carriers of phytoviruses affecting garden crops of the region.Conclusions. In connection with the further prospects for the development of horticulture in the Russian Far East, it is necessary to intensify ecological and virological studies of this section of phytovirology as well as to increase access to agricultural producers with available test systems.","PeriodicalId":41300,"journal":{"name":"South of Russia-Ecology Development","volume":"23 1","pages":""},"PeriodicalIF":0.2,"publicationDate":"2022-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91310733","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Assess the change in the hydrological regime of the Torey Lakes based on a probabilistic forecast of the parameters of the water balance of these reservoirs, taking into account anthropogenic influence.Material and Methods. The study used materials from the state observation network of Roshydromet, Earth remote sensing data, research materials from scientific organisations and other sources of information that are in the public domain. Methods of statistical data analysis, mathematical modeling, hydrological calculations, including the water balance method and methods of processing and decoding satellite information were used.Results. With the implementation of the planned water management project, accompanied by additional non‐returnable water consumption in Mongolia, the consequences for the water regime of the Torey Lakes can be significant, especially in the low‐water phase of the water cycle, when the level decrease in the Barun‐Torey Lake will average 70 cm and in Zun‐ Torey – 80 cm. Through this project, the faster drying of the lakes, on average 2–3 years earlier, will be avoided.Conclusions. The ecological systems of the Dauria region are characterized by a process of cyclic succession and are mainly adapted to the contemporary climatic moisture cycle. For these ecosystems, any changes in external factors are fundamentally important, since they can lead to the irreversibility of natural processes. Based on the results obtained in this study, it is possible to conduct a comprehensive analysis of the anthropogenic impact on the state of the Torey Lakes and nearby ecosystems.","PeriodicalId":41300,"journal":{"name":"South of Russia-Ecology Development","volume":"66 2","pages":""},"PeriodicalIF":0.2,"publicationDate":"2022-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72420031","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of the work was to study the possibility of using an environmentally friendly strain of yeast of the genus Rhodotorula for the bioconversion into fodder carotenoid‐containing biomass of the secondary product of processing pea flour into a protein concentrate (whey).Material and Methods. We used a new strain of Rhodotorula mucilaginosa 111 and by‐products of processing pea and chickpea flour into protein concentrates and potatoes into starch (whey). We used standard and special methods for the analysis of serum and microbial‐vegetable concentrate (FMVC) namely: chemical; biochemical; microbiological; and the determination of toxicity with ciliates.Results. Optimal conditions for growing R. mucilaginosa 111 on pea whey were determined (temperature 16.9°C, pH 7.8, amount of inoculum 1.85%). More biomass was synthesized on pea whey than on chickpea and potato whey – 81 g/dm3. The mass fraction of protein in the biomass is 58.90±3.03% on dry matter and the rate of essential amino acids is 119– 243%. Lipids included 20% saturated and 78% unsaturated fatty acids, linoleic acid – 45.26±0.70%, oleic – 24.04±0.76%, palmitoleic – 6.46±0.31%, palmitic – 13.70±0.81%.

In vitro analysis of the inhibitory activity of dry ethanol extracts of some Artemisia spp. growing in the Novosibirsk region for SARS‐CoV‐2 replication.Materials and Methods. The laboratory strain SARS‐CoV‐2/human/RUS/Nsk‐FRCFTM‐1/2020 was passed on Vero cell culture. Dry ethanol extracts of plant parts (stems, flowers, leaves) of six types of Artemisia were prepared. The types used were: A. vulgaris L.; A. glauca (Pall. Ex Willd.); A. dracunculus L. (from three growth locations); A. absinthium L.; A. frigida Willd.; and A. sieversiana Ehrh. ex Willd. Dry extracts were dissolved in DMSO. In vitro analysis of the inhibitory activity of extracts against SARS‐CoV‐2 (an infectious titer of 103 TCID50/ml) replication was performed in a Vero E6 cell culture. To do this, the method of direct inactivation (neutralization) of virions, as well as schemes of “preventive” and “therapeutic” of cells, were used.
