Abstract
The results of three years of research on the development of a biological biocidal preparation for the control of harmful arthropods based on ethanol extracts of biologically active substances of Lobel’s hellebore are presented. The first experimental samples of the drug were tested on a number of arthropod phytophagous species. In laboratory experiments, the most effective and promising samples of the preparation for further research were determined. It has been established that their biological effectiveness depends on the technology of manufacturing preparations, the content of the active composition of substances, the concentration of the working solution and the species of phytophages. Individual samples were comparable in effectiveness with traditional insecticides from the avermectin group.
