abstract = "One of the major problems in agriculture are Fusarium species which cause fusariosis in wheat,
corn, tomato, melon, watermelon, onion, peas, and beans. Also, Fusarium can synthesize
thermostable mycotoxins which can lead to certain diseases if they were found in food.
Currently, chemical fungicides are mostly used to prevent the occurrence of fusariosis disease,
but the resistance of pathogens to such treatment is being more and more widespread. Soil
microorganisms help in plant defense and growth. The rhizosphere fungi have an important role
in the mutual exchange of nutrients with plants and they can establish specific interactions with
plants. Such rhizosphere fungi are known as plant growth-promoting (PGP). These PGP fungi
affect the better plant growth through the synthesis of certain phytohormones but they also have
the function as biocontrol agents. They can inhibit the growth of phytopathogens through direct
mechanisms of antibiosis, mycoparasitism, and competition.
The goal of this research was an investigation of the antagonistic effect of Trichoderma
harzianum TR1 and Trichoderma citrinoviride 1V on Fusarium oxysporum and Fusarium
graminearum. The antagonistic effect was examined through two tests: Dual culture test (DUAL
test) and the effect of volatile organic compounds (VOCs) of Trichoderma strains on the growth
of Fusarium strains. Also, the cell-wall degrading enzymatic activity of T. citrinoviride and T.
harzianum was examined. The results showed that antagonistic activity of Trichoderma strains
varies from moderate to high. Mycelial growth inhibition by T. citrinoviride was 44% for F.
graminearum and 67% for F. oxysporum. T. harzianum inhibited F. gramminearum growth for
59% and F. oxysporum for 66%. Based on the results, it was concluded that T.harzianum and
T.citrinoviride can be considered biocontrol agents for F. oxysporum and F. graminearum.",
