Aim. Determination of the ivermectin influence on plant pathogenic species of Fusarium genus; particularly, F. graminearum and F. oxysporum. Methods. The susceptibility of studied strains (F. graminearum F-55756 and F. oxysporum F-54635) to ivermectin was measured in vitro with the agar diffusion method. Ivermectin in concentrations from 0 to 3 mg/ml was poured into the wells made in media for that purpose. Further, mycelial discs of F. graminearum and F. oxysporum strains were placed into the central regions of Petri dishes, which were then maintained in the dark at 25 °С. Ivermectin influence on growth and morphology of studied strains was estimated after the 7 days using the ImageJ software and methods of statistical analysis to determine the most effective concentrations. Results. As the result, it was found that at 1 mg/ml concentration and above the fungistatic effect is observed and the 3 mg/ml concentration appeared to be the most effective one. Thus, the percentage of mycelium area in comparison with control at this concentration was 83,91 % for F. graminearum F-55756 and 69,95 % for F. oxysporum  F-54635. Conclusions. The ivermectin effective fungistatic action on the studied strains was observed giving the reason for further analysis of the ivermectin influence on other strains of Fusarium complex species and search of molecular targets of its action.
