Hyphal interaction mechanism between some fungal biocontrol agents and some cucurbitaceous damping-off pathogens [electronic resource].

Includes reference.

Light microscope was used to dual cultures, containing the tested fungal biocontrol agents: namely; Trichoderma harzianum, T. viride, T. konningii and Gliocladium roseum and some cucurbitaceous damping-off pathogens: namely; Rhizoctonia solani, Pythium ultimum, Fusarium solani and Alternaria alternata. Microscopic examinations indicated that growth of the mycoparasitic fungal mycelium was characterized by the formation of highly active, thin, dense and well-branched hyphae compared to those of the tested pathogens, where hyphae were thicker and less branched. This behavior was common in most of the tested mycoparasitic isolate/pathogen interactions.
