Abstract
The studies of the phytosanitary condition of elm trees in plantations of different functional purposes have been carried out. It was established that in the urban agglomeration on elm trees stem and butt rots, necrosis of branches, mycoses and bacteriosis predominate. Factors causing the development of infectious diseases Ulmus L., which can be attributed to a high anthropogenic load on the soil, mechanical damage to the trunks, violation of the technique of pruning the crown were identified.
