White mistletoe as a semi parasite plant with a wide selective ability parasitizes many autochthonous species of willow and poplar. The problem seems topical since the mistletoe invasion is rather extended and is almost extreme and Ukraine may face an ecological disaster. If all the trees in the state are not cleared from this hemiparasite in two or three years, the invasion will go on a new circle and in 10-15 years it will practically be too late to control mistletoe. That’s why we used a rating estimation by V.P. Shlapak and others (Shlapak, Muzyka, Sobchenko, Marno, Tysiachnyi, 2010) which estimates the damages of woody plants affected by white mistletoe after two 7-rating estimation and index of complex estimation of damaged plants with mistletoe (CEDM). Researches were conducted in Bila Tserkva town (Tabl. 1).

High level of damage has Populus alba L., Populus nigra L., Populus balsamifera L., Salix alba L., Salix alba L. ‘Viteline Pendula’. Low damage level of crown is characteristic of Populus italica (Du Roi Moench.), Salix caprea L., Salix fragilis L., Salix pentandra L., Salix matsudana Koidz. As usual, crown suffers the most damage (16-25 “bushes”) on one tree and the trunks of affected trees suffer the least damage. We noted very intense damage of 11-12 scores at roadside plantings with Populus alba L., Populus nigra L., Salix alba L. The varieties with middle and low level of lesion caused by Viscum album are promising for use in landscaping and planting settlements in Ukraine. Nowadays Viscum album is one the most dangerous factors which influence viability, longevity and ornamentality of Salicaceae representatives at green planting in Bila Tserkva town. There is a great number of trees affected by mistletoe whose fruits promote its propagation and birds that eat its fruits promote its expansion. It’s necessary to cut trees systematically for avoiding its fruiting in order to destroy mistletoe. Strongly affected trees must be chopped off. To solve this problem, we need to embrace municipal and state course of controlling actions with white mistletoe. Besides it must be authority to allocate funds for carrying out these actions. Promising species for landscaping and gardening of settlements in Ukraine: Populus italica (Du Roi Moench.), Salix caprea L., Salix fragilis L, Salix pentandra L., Salix matsudana Koidz.
