Abstract:
The corn root rhzosphere and 23 local microorganisms strain belonging to the Trichoderma
family were isolated from other sources. From these strains, during the experiments,
Trichoderma sp 4 micromiset strain was selected due to its high antifungal activity. The
temperature of 24-28°? for the growth of the fungal strain of Trichoderma sp 4, the nutrient
medium was determined to be optimal in the potato dextrose agar with a ?? of 5-7. Fusarium
oxysporum, Verticillium dahliae and Alternaria alternate were found to exhibit active
antagonistic properties against phytopathogenic fungi.
