Environment protection is a very difficult and important problem and it covers many interconnected aspects. Among these aspects green planting management of a modern city is to be mentioned. Since green plantings are a sort of “lungs” of a city, therefore, especially today it is important to protect them from damage by pests and diseases. Our aim was to carry out a pathological research on green plantings of Tbilisi and to estimate a condition of the most common plants on this territory. With this end in view it was necessary to study the species composition of the pests (insects and diseases) on plants in Tbilisi plantings (parks, squares and roadside areas). The pathological monitoring of plants has been carried out in various districts of Tbilisi; visual observation has established that the plants of planes and box tree were the most damaged species. The detailed research also has revealed the pests: sycamore bug Corythucha ciliata and box tree moth Cydalima perspectalis. The bushes of box tree also were diseased by the phytopathogen organisms Volutella buxi and Alternaria alternata. Frequency of spread of plant pests and diseases, their pathological status, and condition have been studied.
