Although Trichoderma species are sometimes found associated
with Meloidogyne spp. in field soils and can penetrate
their eggs and females, their successful deployment as a biocontrol
agent against nematodes may depend on a thorough
understanding of this fungus. Compatibility between the fungal
isolate, host cultivar and soil substrate may, therefore, play
an important role in the proliferation and persistence of
Trichoderma spp. in soil. It is important that biocontrol isolates
are able to compete and persist in the environment,
rapidly colonize and efficiently proliferate on newly formed
roots
