| Summary: | The study of the effect of the strains of the fungus Trichoderma: Trichoderma atrobrunneum VKPM F-1434, Trichoderma harzianum 5/14, Trichoderma Lixii T4/14 on the number of micromycetes populations of the pathogenic fungi Fusarium oxysporum isolate B/14, Fusarium oxysporum isolate MOS509, Fysarium oxysporum isolate IMI58289 in vitro. It was found that the Trichoderma atrobrunneum fungus strain VKPM F-1434 showed the highest degree of inhibition on 10 days of cultivation with phytopathogenic microorganisms, which was 100 %. The study revealed that all Trichoderma species are capable of producing lytic enzymes. Trichoderma atrobrunneum strain VKPM F-1434 exhibits strong lipase and chitinase activity and average proteinase activity. In addition, Trichoderma atrobrunneum strain VKPM F-1434 has a growth-promoting ability, which was reflected in the germination of seeds of cucumber “German F1”. The maximum values of indicators of germination energy were noted – 98.4 % and germination – 100 %.
