The objects of study were coniferous plants aged from 6 to 10 years. The study involved such plants as Siberian spruce (Pícea obováta), prickly spruce Hoopsi (Picea pungens Hoopsii), western thuja Smaragd (Thuja occidentalis Smaragd), thuja western Brabant (Thuja occidentalis Brabant). The subject of the study was the pathological symptoms manifested on the aboveground plant organs. The plants were planted in 2015 at the age from 6 (thuja Smaragd and thuja Brabant) to 10 (prickly spruce and Siberian spruce) years. The studies were conducted from May 2016 to September 2018 inclusive. During the initial examination, which was carried out on May 28, 2016, on all conifers, there was a loss of decorativeness, partial premature drying of shoots and falling of needles. When using biological products, a persistent stimulating effect is very noticeable — the general condition of conifers improves, this makes it possible to recommend tank mixtures for use, the composition of which is less toxic. Thuja Brabant turned out to be the most unresponsive to drug treatment.
