Biofumigants and crop rotations are also among the environmental friendly methods that can be used to control soilborne pathogens especially Fusarium wilt. In addition, the research examined the possibility o Commonly used fungicides are usually inexpensive, but their efficacy is disputed due to the complications associated with diverse pest management strategies. DNA samples isolated from Forl ZUM2407, Forc V032g and Fox Fo47 strains were used to check the efficiency of the fragment amplification with primers OMP1049 and OMP1050. In our opinion, the combination of chemical fungicides and biological control agents can successfully inhibit soilborne pathogens, but more research is required to determine the effect of these methods on the soil microorganisms populations. The filamentous fungus Fusarium oxysporum causes vascular wilt disease in a wide range of plant species and opportunistic infections in humans. Cell fusion in yeast is negatively regulated by components of the cell wall integrity pathway. In addition, the occurrence of both pathogenic and nonpathogenic strains on the root stimulated resistance mechanism in plants, therefore demonstrating their importance in the induction of local resistance [11].

On the other hand, multicopy orthologuous sequences are convenient targets for qPCR due to the wide range of strains, which can be detected due to the high sensitivity of the reaction. This means that some of the unrelated Fox strains that are pathogenic to the same plant species can miss an anonymous fragment, which is the target for qPCR. In, Waite, B.H. ; visualization, M.L. There is evidence that nonpathogenic F. oxysporum, which is characterized among endophytic fungi, can stimulate the defense response of host plants when plant pathogens attach them; furthermore, it has been found to increase resistance to environmental stress and enhance the production of essential hormones such as auxins and gibberellins, which are known to activate the plant growth [11, 13, 14]. Fusarium oxysporum is a ubiquitous soilborne pathogen that causes vascular wilt and root diseases on a broad range of economically important crops such as banana, tomato, melon, and cruciferous vegetables.
