The study was conducted for the purpose to determine the efficiencies of alternative biopesticides to be used in the control against Halyomorpha halys. NeemAzal® and water were used for the control. The most commonly-seen efficiency rates were determined to be 72% with NeemAzal® in the nymph stage.
A method for obtaining biopesticides from plant materials based on application of a microwave electromagnetic field in the process of extraction is being studied. The article presents results of an experimental study of the efficiency of microwave extracts. The expediency of extracting biologically active substances in a microwave field is shown. The application of the method makes it possible to proceed to the production of large volumes of preparations and to reduce the volumes of chemical agents. A device is proposed for implementing this method.
