Over the years, use of biological preparations to control causal agents of plant diseases has become increasingly significant. In addition, the contribution may be attributed to the advantages of the preparations manifested in environmental protection and safe food production. Besides their efficacy approved on individual pathogens, these preparations often increase the resistance and act as growth promoters as well. A 2% concentration of the Ekstrasol 55 preparation has proven to be the most efficient, as the growth of Cochliobolus sativus ceased completely. Between the applied concentrations of 1% and 2% there were no statistically significant differences in the growth of mycelia of the fungus Fusarium graminearum. Between the growth of Cochliobolus sativus and the width of the inhibition zone, a very intensive negative correlation was found (r=-88.9%). The principle of electron treatment is the limitation of the effect of low-energy electrons to the outer layers of the seed in order not to damage the embryo. This technique is especially advantageous because of its compatibility with integrated plant protection systems. Efficacy in field conditions in Tilletia tritici after e-treatments was 92.7% at Novi Sad and 91.5% at Kragujevac.
