Використання нанопрепаратів у вирішенні проблем збереження зелених насаджень урболандшафтів

Abstract

Nowadays preservation and rehabilitation of green spaces is a priority task under conditions of increasing of the technogenic impact of urban environment on inhabitants of the city. Timeliness of these studies is necessity to solve the environmental problems of large cities on the one hand and the lack of scientifically well-grounded concept of stabilizing of green spaces under conditions of cost reduction from the other side. In landscape industry preparations of chemical, microbiological and plant origin are used for nutrition and plant protection. Taking into account that the use of pesticides on the territory of green spaces of megacities is limited or prohibited by law the use of nanoparticles is most appropriate. The purpose of the study is to analyze the market of biopesticides presented in Ukraine, systematization and generalization by the components of preparations authorized for usage and recommendations on their usage in greenery for increasing plant resistance against adverse environmental factors. According to the results of assessment of the positions of the list of the State Register of Pesticides and Agrochemicals Permitted for Use in Ukraine (List) it was found that only 3% of the total number of submitted preparations are recommended for use in greenery. Taking into account the prolonged influence of nanoparticles and their bioactivity after use of nanoparticles there is an increase in the efficacy of the physiological and biochemical processes, optimization of growth and development of trees, shrubs, herbaceous plants and their resistance to stress factors of the environment. Established that the sustainable development and conservation of biodiversity of urban spaces, reduction of pesticide load and environmental remediation can be ensuring by the effective usage in the greenery of nanoparticles. Keywords: urban spaces, greenery, nanoparticles
