The impact of urban ecosystem factors leads to the weakening of introduced and wild-growing tree and shrub plants, which makes them more accessible to diseases and can eventually lead to the loss of decorativeness, fragility and even plant death. Phytopathological monitoring was carried out using routing research methods. They examined the urban plantings of 5 categories, which differ in the degree of anthropogenic change. During the research, they determined the type and the nature of specific species diseases, the pathogen causing it, and the intensity and the prevalence of a number of diseases. An ocular 5-point scale was used to take into account the intensity of diseases: 0 points - the absence of lesions; 1 point - up to 10% of the surface is damaged; 2 points - 11 - 25% is damaged; 3 points - 26 - 50% is damaged; 4 points - more than 50% of the surface is damaged. The prevalence of the disease was calculated in %, to the total number of inspected plants. The result of research showed that trees and shrubs were affected by three groups of diseases most often: spotting, rust and powdery mildew. The most affected species in the urban environment under study: Tilia córdata Mill., Malus domestica Borkh., Acer platanoides L. Key words: plant diseases, green plantations, pathogens.
