Title : Development of a bionano-insecticide and efficient PGPR microorganisms synthesized with nanoparticles for organic cotton (Gossypium) cultivation
Abstract:
Objective: The study aims to investigate bionano-insecticides and efficient Plant Growth-Promoting Rhizobacteria (PGPR) microorganisms synthesized with nanoparticles, containing halophilic and extremophilic PGPR microorganisms, and toxins from the Bacillus thuringiensis strain for the cultivation of organic cotton (Gossypium).
The utilization of entomopathogenic microorganisms and effective halophilic and extremophilic PGPR microorganisms in the creation of a nanobiotechnological product represents a new direction in Kazakhstan's biotechnology. It is worth noting that the application of entomopathogenic microorganisms and effective halophilic and extremophilic PGPR microorganisms in the development of a bionanotechnological product for the cultivation of organic cotton (Gossypium) will be studied for the first time in Kazakhstan, as they are underexplored globally and require in-depth investigation in this field.
Sustainable agriculture requires addressing issues related to both agriculture and the environment. High crop yields amidst environmental degradation can be achieved through the efficient use of biofertilizers and biopesticides. In recent years, there has been a slowdown in the growth of the global market for chemical pesticides and fertilizers, coupled with an increase in the development and production of biological preparations. It is expected that by 2050, sales volumes of chemical and biological pest control agents will reach an equivalent level. An object of great value, with significant potential in agriculture and of high interest for the development of an insecticide, is the toxins produced by the Bacillus thuringiensis strain and the growth-promoting, indigenous halophilic and extremophilic PGPR bacteria resistant to local climatic conditions.
Within the framework of this study, experimental research will be conducted to acquire new knowledge in the field of bionanotechnology, encompassing halophilic and extremophilic PGPR microorganisms and toxins from the Bacillus thuringiensis strain for the cultivation of organic cotton (Gossypium).
The search and selection of strains from natural sources (soil and cotton rhizosphere) are ongoing for the creation of new bionanopreparations. In the implementation of this project, indigenous strains of entomopathogenic microorganisms, as well as halophilic and extremophilic microorganisms possessing PGPR properties, isolated from the soils and rhizospheric microbial populations of cotton, will be studied. To carry out this project, bionano-insecticides and growth-stimulating modified bionanopreparations synthesized with silver, silicon, and other elements containing toxins from entomopathogenic microorganisms and the PGPR properties of bacteria will be developed.
Testing of the bionano-insecticide and effective PGPR microorganisms modified with nanoparticles, containing halophilic and extremophilic PGPR microorganisms, will be conducted in model experiments under both laboratory and field conditions. An economic evaluation of the effectiveness of applying bionanopreparations will be provided based on key production indicators.
