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. In order to increase the productivity, it is reasonable to develop an extractor of continuous action, and for this purpose the input and output channels should be designed so that their length corresponds to the length of the below cutoff waveguide that provides operation safety of the personnel working with the microwave device. For transfer of electromagnetic energy, it is rational to use horn antennas, and diameter of the channel through which raw materials with extractant pass should not exceed two depths of penetration taking into account the effect of thermal conductivity.
