Mycoparasitism of Trichoderma species: A SEM photomicrographs indicate the holes (yellow arrows) caused by the interaction between Trichoderma harzianum and root rot pathogen (Rhizoctonia solani) after 4 days of incubation, (magnification 500 ×: bar = 10 μm). B Dual culture assay shows the T. harzianum interact with R. solani in vitro. C Hyphal interaction of Trichoderma asperellum and a root rot pathogen (Fusarium solani) after 5 days of incubation, yellow arrows show the coiling of hyphae (magnification 1000 ×: scale bar = 10 μm). D Antagonism of T. asperellum strains against F. solani following a confrontation test
