Recently rational nature management of the urban flora in the sphere of the influence of anthropogenic factor on the life state of plants has become one of the urgent problems of the environmental protection. The urban flora used in urban floristry should include the adapted species resistant to abiotic and biotic stress-factors, as well as to damage by entomological and phytopathological agents. The assessment of flowering shrubs-introducents and native species in the urban environment of the city of Orel allowed us to rank the plantings of general and limited use andplantings for special purpose accordingto their life state for the tolerance to stress factors. The promising species for the urban floristry are: Berberis thunbergii, Chaenomeles japonica, Lonicera caprifolium, Physocarpus opulifolius, Philadelphia coronaries, Sorbaria Sorbifolia, Syringa velutina and Weigela florida.

The article presents the results of monitoring the entomo- and phytopathogenic organisms of Rosa L. in the conditions of the modern urban environment. In recent years, this issue is of particular relevance due to changing weather conditions and environmental anxiety, and the main developments on this topic date back to the middle of the last century. Monitoring studies have shown that the greatest harm to rose plantings is caused by sucking pests and fungal diseases. It is possible to reduce their aggressiveness by creating conditions for better growth and development of plants, increasing their resistance, which was achieved by a complex of applied fertilizing bases and biologically active substances.
