The drawbacks of the existing methods of disinfection of grain and seeds are shown, a conclusion is made about the absence of a highly effective “green” method, which may be based on low frequency electromagnetic oscillations (up to 1 kHz), which have an inhibitory me chanism. The possibility of deep disinfection and an increase in laboratory germination of seed satcertain low frequencies has been investigated; thanks to their directional (resonant) action, energy savings and other advantages are achieved.

The disinfecting effect of the higher harmonics of the magnetic field has been substantiated, and their relationship with the equipment parameters has been shown. Using the analysis of spectrograms and a laboratory experiment, the inhibitory 23rd, 25th, and 30th harmonics were established, the presence of which in the spectrum of a two-pole electromagnet provides a high disinfection effect. The necessity of concentrating the spectrum of magnetic disinfecting equipment at the frequencies of the indicated harmonics in order to increase the efficiency of the method has been proved.
