Throughout the research, it was found that the seed treatment with EHF MWF of EHF in the determined irradiation modes or with the additional treatment with the growth regulators Mars EL (wheat) and Radostim or Albit (barley) causes a decrease in the spread and development of root rots in the crops of these agricultural plants. In the case of winter wheat, the spreading and development of root rot in the full ripening phase when treated with MWF of EHF of 1.8 kw/kg 15 sec., MWF of EHF of 0.9 kw/kg 45 sec and MWF of EHF of 1.8 kw/kg 15 sec+Mars EL made up 4.9 and 2.1%, 5.4 and 2.0%, 4.9 and 2.1% respectively, while under control these indices were 9.7 and 4.0% respectively, and in the case with Vitavax 200 FF-6.1 and 2.4%. The pre-sown seed treatment with EHF MWF of EHF in the modes of 0.9 kw/kg, 45 s or 1.8 kw/kg, 20 sec., with Radostim and Albit growth regulators, as well as in their combination, causes a decrease in the spread and development of root rots throughout the growing season of barley varieties. The application of MWF of EHF in the modes of 0,9 kw/kg, 45 s. or 1,8 kw/kg, 20 sec. followed by treatment at a half-reduced rate of Vitavax 200 FF rate (1.25 L/ha) provided a lower degree of root rot of plants of the Aspect barley varieties in the stalk shoot phase than the application of the full rate of the treatment agent when the spread was lower by 2.4 and 2.2%, respectively, and the development by 0.3 and 0.5%.
