The box tree moth Cydalima perspectalis (Walker) (Lepidoptera: Crambidae) is one of the most alien insects found in the Buxus areas of Georgia and World. Many methods have been used to control this pest up to now. But, the problem is still going on. In this study, insecticidal effects of the essential oils obtained from plants Artemisia absinthium L., Seriphidium santonicum (L.) Sojak, Seriphidium spicigerum (K.Koch) Poljakov, Cuminum cyminum L., Mentha pulegium L., Origanum majorana L., Origanum onites L., Origanum syriacum L., Origanum vulgare L., and Satureja hortensis L. on C.perspectalis were tested in laboratory conditions. In this context, larvae of the 2nd and 5th instars of C.perspectalis were exposed to essential oils at doses of 10, 15 and 20 μl/petri for 24, 48, 72 and 96 h. All of the essential oils used in the study caused mortality at different rates; the highest effect on 2nd and 5th instar larvae of C.perspectalis was obtained with the essential oil from O.onites with a mortality rate of 80.0-71.6%. The oils from O. onites (73.3-65.0%),

The significance of organic plant growth stimulants, in the development of sustainable agriculture and increasing the fertility of degraded soils has sparked the interest of scientists and practitioners working in the field of agriculture in recent decades. On the world market, there are numerous plant growth biostimulants of various origins and compositions, as well as numerous research analyzing their impacts and roles. The study aimed to determine the novel biological activity of the new Georgian biostimulants Bactofert-L Blatt, Bactofert-L Boden, and Bactofert-L Si, which were developed by "Geofert" LTD. For this reason, Cucumber seedlings were obtained, and their growth intensity was studied according to root and stem length, leaf assimilation surface, and seedling mass under the action of 0.15 percent solution of biostimulants in laboratory conditions. Other biostimulators of Georgian and foreign origin available on the Georgian market were also included in the study to examine the biological activity of biopreparations.The research was carried out using the GOST-54221-2010 technique. In comparison to the control variant and other experimental stimulants, studies have shown that all three Georgian bio preparations - Bactofert-L Blatt, Bactofert-L Boden, and Bactofert-L Si - have strong biological activity. The best biostimulator for plant growth boosters has been determined as Bactofert-L Boden.
