The world market of synthetic pyrethroids is estimated more than at 2.5 bn. dollars and will grow in the next years. Numerous works of domestic and foreign authors are devoted to toxicology of pyrethroids, however the issues related to pathogenesis of an acute poisoning of animals with pesticides of that group as well as the principles of laboratory diagnostics at an early stage of intoxication and pathogenetic therapy at poisoning warrant further investigations. For many years deltamethrin has been successfully used in plant growing as well as in animal husbandry creating a poisoning hazard in case of violation of treatment regulations. Morbidity and clinical outcome depend largely on severity of functional endocrine and immune systems disorders. The purpose of the study was to determine dynamics of adaptive and compensatory reactions in animals at an early stage of an acute intoxication with deltamethrin. In experiment white laboratory rats as an established mammal model in biomedical research were used. The experiment was performed on male rats (weight of 180-200 gr) arranged in 6 groups (of 10-12 rats each). Animals from groups II, IV and VI have been subjected to an acute peroral intoxication with deltamethrin (Butox 50, Intervet, Netherlands) in a dose of 43.5 mg/kg of body weight. Rats of groups I, III and V served as control. Rats from different groups were put out of the experiment sequentially: I and II - in a day; III and IV - in three days; V and VI - in a week after the beginning of the experiment. Glucose content was estimated in whole blood of rats, and concentration of insulin and corticosterone was assayed in blood serum. Pieces of animal timus were fixed in 4 % neutral formaldehyde, dehydrated in alcohols with the increasing concentration and embedded into paraffin. Histologic sections at 3-5 microns in thickness were made with the rotational microtome and stained with haematoxylin and eosin, and also according to Van-Giezon. For identification of mast cells the histologic sections were stained with Bismarck brown to Shubich. Increase in blood corticosterone, insulin and glucose levels by 46.3 (p = 0.0001), 31.9 (p = 0.0139) and 25.6 % (p = 0.0052), respectively, was found in a day after poisoning with deltamethrin. On day 3 after poisoning the blood concentration of corticosterone and glucose in rats remained high along with a decrease in insulin content. Hypocorticosteronemia and hypoglycemia were observed on day 7 after poisoning, with the insulin level close to control values. Corticosterone and glucose content has been reduced by 17.3 (p = 0.0407) and 19.8 % (p = 0.0267), respectively, compared to control. Photomicrographs showed a reduction in the number of thymocytes, activation of apoptosis, an increase in quantity of mastocytes along with an intensification of degranulation as well as development of haemodynamic disorders in thymus when poisoning rats. In a week after intoxication the thymocytes level was partially restored. No animal died during experiment which evidences the efficiency of adaptation and compensatory mechanisms in experimental rats, including hypothalamic-pituitary thymic system. Results of our researches make a contribution to understanding compensatory and adaptive mechanisms under experimental intoxication, and allow estimating functional capabilities of body systems when developing pharmacological correction at poisonings. © 2016, Russian Academy of Agricultural Sciences.

One of the most important factors in the intensification of greenhouse tomato production is the introduction of new high-yielding hybrids which are adapted to new technologies and unfavorable climatic conditions. The present investigation was carried out in the Korkyt Ata Kyzylorda State University greenhouse between 2010 and 2015, to study the performance of different tomato hybrids in terms of growth, yield and quality inside the greenhouse in the PreAral area conditions in Kazakhstan. Seventeen tomato hybrids selected from the Netherlands, Israel and Russia were grown on a substrate of sawdust in the conditions of the extended culture. Based on the results obtained, the most productive hybrids and those best adapted to the climatic conditions of the area are identified and the fruits’ quality assessment and cost-effectiveness analysis are given. The best yield and fruit quality results were obtained from hybrids from the Dutch selection. The best variety for all indicators - productivity, yield of standard products, fruit taste and largest profit - was the Panekra hybrid. Lilos F1, Maxitos F1, Gravitet F1, Klepton F1, Esmira F1 and Clarabella F1 hybrids also had high productivity, good fruit quality and relatively high profit. These hybrids are recommended for greenhouse soilless culture in PreAral area conditions. © 2017 Elina Bakhtiyarovna Dyamurshayeva, Rakhym Iskendirovich Kudiyarov, Igor Aleksandrovich Bobrenko, Gulsym Zykriyaevna Sauytbayeva, Nurlan Zhetkergenovich Urazbayev, Galina Evgenyevna Dyamurshayeva and Salima Izbaskanovna Sadybekova.

The spring wheat belt of Western Siberia and Northern Kazakhstan covers more than 15 million ha. While moisture stress is the main factor limiting production, rusts also represent a major challenge, especially in years with higher rainfall. Stem rust was not considered economically important until 2015 when a local epidemic occurred in the Omsk region of Russia and neighboring areas of Kazakhstan and affected more than 1 million ha. It occurred again in 2016 though the spread, severity and losses were less. This study used 16 pathotypes and 17 molecular markers to characterize a set of 146 spring wheat varieties and breeding lines identified as stem rust resistant in Kenya and the Kazakhstan–Siberia region for the presence of major genes. The genetic basis of resistance in the material was limited to Sr25, Sr31, Sr36, Sr6Ai, Sr6Ai#2, and some unknown major genes. Genes Sr25 and Sr6Ai#2 also provided high levels of resistance to leaf rust through linkages with Lr19 and Lr6Ai#2. Adult plant resistance to stem rust was observed in 26 genotypes (16.5 %), including eight possessing Sr57 gene. The high risk of stem rust—as indicated by the 2015 Siberian epidemic—means that there is an urgent need to diversify the genetic bases of resistance and to promote resistant varieties with farmers. © 2016 Springer Science+Business Media Dordrecht

Leaf rust represents the major threat to wheat production in Russia and Ukraine. It has been present for many years and epidemics of the pathogen occur in different regions on both winter and spring wheat. In some regions there is evidence of more frequent epidemics, probably due to higher precipitation as a result of climate change. There is evidence that the virulence of the leaf rust population in Ukraine and European Russia and on winter wheat and spring wheat is similar. The pathogen population structure in Western Siberia is also similar to the European part, although there are some significant differences based on the genes employed in different regions. Ukrainian wheat breeders mostly rely on major resistance genes from wide crosses and have succeeded in developing resistant varieties. The North Caucasus winter wheat breeding programs apply the strategy of deploying varieties with different types of resistance and genes. This approach resulted in decreased leaf rust incidence in the region. Genes Lr23 and Lr19 deployed in spring wheat in the Volga region were rapidly overcome by the pathogen. There are continuing efforts to incorporate resistance from wild species. The first spring wheat leaf rust resistant varieties released in Western Siberia possessed gene LrTR which protected the crop for 10-15 years, but was eventually broken in 2007. Slow rusting is being utilized in several breeding programs in Russia and Ukraine, but has not become a major strategy. © 2010 Springer Science+Business Media B.V.

This article defines the possibilities of using the cluster approach in vegetable and potato cultivation, by forming vegetable micro-clusters, which, unlike the ones used today, require the formation of a favorable institutional environment for innovative development of the industry. It has been substantiated that cluster development of vegetable and potato cultivation is the basis of sustainable development of rural territories, resolving the social and economic problems and development of local self-government. The main role in stabilizing the business sector belongs to the infrastructure support in the market of the region. © Oksana viktorovna shumakova, 2016.

The distribution of stomatocysts of chrysophyte algae in the plankton of bodies of water of different types in the basin of the middle reach of the Irtysh (at the Omsk Region), as well as in the plankton and in fouling of the deep-water oligotrophic lake Teletskoe (Gorny Altai) has been considered. The classification of morphotypes of stomatocysts has been carried out. The number of morphotypes found in plankton samples from bodies of water of the middle Irtysh basin is 30 and, in Lake Teletskoe, 60. Four similar morphotypes of cysts were revealed for the bodies of water under investigation. © 2012 Pleiades Publishing, Ltd.
