Fungal diseases of leaves are the dominant biotic factors of deterioration of sanitary state of main wood species, used in planting of greenery in Belarusian cities. 24 phytopathogenic species are discovered in the green plantations. The following measures allow to control development of fungal leaf spots: from agrotechnical – type of planting, timely care of woody plants; from chemical – 3–4-fold spraying of fungicides scor, falcon, prozaro, previcur in nurseries. Times of treatment are coordinated with dynamics of pathogens. At the sametime biological efficacy reaches 79–100%. Application of biological preparation frutin is effective on the horse-chestnut and maple plantings in the urban conditions. Biological efficacy reaches 80–86%.
