Abstract
The comparison between the effects of the used different media (PDA, Czapek-Dox agar, malt extract agar and soil extract agar) in growing both parasitic fungi (Rhizoctonia solani, Fusarium oxysporum F. sp. cucumerinum and Sclerotinina sclerotiorum and the antagonistic fungi (Trichoderma harzianum, Gliocladium roseum and G. virens) showed that the available media for growing the antagonistic fungus T. harzianum in the presence of the pathogen R. solani were respectively molt extract agar followed by P.D.A., while the opposite results for growing the pathogenic fungus R. salani in the presence of T. harzianum was soil extract agar followed by Czapek-Dox agar.
Also, we found that the available media for growing the antagonistic fungus T. harzianum in the presence of the pathogen F. oxysporum were Czapek-Dox agar followed by soil extract agar, P.D.A. and malt extract agar, respectively. While \the best media for growing the same antagonistic fungus T. harzianum in the presence of S. sclerotiorum were soil extract agar, Czapek-Dox agar, P.D.A. and malt extract agar media, respectively. In case of the antagonist G. virens with the R. solani, we found that the available media for the best growth was the P.D.A., while the other three media type gave negative growth for G. virens and positive growth for R. solani. Also, the whole media were available for growing the antagonist G. virens  in the presence of the pathogen F. oxysporum cucamerinum but the P.D.A. was the best between all media for growing the two fungi, while the best media for growing the same antagonistic fungus in the presence of the pathogen S. sclerotiorum were malt extract agar and soil extract agar followed by P.D.A. and Czapek-Dox agar media. In the presence of Gliocladium roseum with the three pathogenic fungi (R. solani, F. oxysporum F. sp. cucumerinum and S. sclerotiorum), all media gave less growth (decreased) for the antagonistic fungus G. roseum and positive growth (increased) all pathogenic fungi.
