The negative economic consequences of using sun-flower seeds infested by molds Phomopsis helianthi Munt. Cvet. et al. as inoculums are described in the article. The necessity of finding the ways of these molds inactivation alternative to the way of chemical disinfection, and the advantages of usage of electro-physical ways of seeds’ treatment for this purpose and in particular electromagnetic field (EMF) of microwave frequency (MWF) are explained. The construction of the laboratory experimental setup is shown, on the bases of which the process of Flagman variety of sunflower seeds disinfection EMF MWF is researched. The testing technique is described too. The observable sowing sunflower with the starting infection rate by phomopsis at 22% is treated for different durations in the EMF MWF, being in either static or continuously mowing layers. As result of these experiments the particular rates of treatment providing the total disinfection of sunflower seeds from molds Phomopsis helianthi Munt. Cvet. et al. are revealed and the discovered contradictions in the experiments’ results are explained
