Abstract

Now in the Republic of Kazakhstan the environmental problem, the bound to consequences of longterm use in agriculture for pest control of agricultural plants of pesticides chemical means of protection ofplants is particularly acute. Though now their use is almost forbidden, owing to high toxicity concerningbioobjects of soils and reservoirs, there was other problem, the bound to need of creation of new ecologically dangerous objects – storages (warehouses) for huge amounts of unused pesticides the substanceshighly dangerous to all alive organisms. Construction of such storages was dictated in due time by whatin recent years, in the conditions of noticeable decrease in demand for pesticides, owing to their poortarget effectiveness, negative impact on objects of a surrounding medium, use of these medicines con siderably decreased, but, considering a possibility of their application in the long term in the presence ofdevelopments for successful protection of the organisms occupying objects of the external environmentthe soil, water and air from effect of pesticides, in a number of regions express storages for the pesticideswhich are available in warehouses were constructed. In particular, in Talgarsky district of Almaty region.Most of the research conducted in this direction is devoted to the study of the target activity of pesticides in the process of their application in agriculture.However, the great attention of researchers is also required by the problems associated with the influence of pesticide storage facilities on the ecology of the environment, on the physiological activity ofmicroorganisms and other components of water and soils, which in such studies can serve as markers ofchanges caused by the presence of pesticides and products of their disintegration in the medium. In particular, on their metabolic activity it is possible to estimate intensity and the nature of influences of toxicsubstances, for example pesticides, on metabolic processes in cages of soil microorganisms immediately,i.e. the metabolic capacity of soil microbial communities in areas of burial of pesticides.Such researches, on the one hand, will allow to obtain reliable information not only about influence ofstorages of pesticides on an ecological situation of the explored region, but also have the prognostic valuesince allow to judge possible changes of microbial potential in objects of the external environment in thepresence of the significant amounts of pesticides in storages. Not less important and the fact that studyingof microbial communities of the soils polluted by pesticides is necessary both for assessment of biologicalrisk, and for selection of perspective agents for technology of bioremediation of natural objects.Key words: microorganisms, pesticides, microbial diversity, strain, identification, genetic information.
