Trichoderma viride was identified as a mycoparasite against Ceratocystis paradoxa. When grown near
the pathogen, T. viride was seen entwining around the pathogen mycelium. It was stimulated to
produce branches that grew directly to the pathogen mycelium. Firm attachment on the pathogen
conidia resulted in the penetration and successful growth of T. viride. Some of the impregnated C.
The oil palm (Elaeis guineensis Jacq.) industry provides
direct employment to about four million Nigerian people in
about twenty oil palm growing states in Nigeria, and
indirectly to other numerous people involved in processing
and marketing (Ahmed, 2001). Despite the enormous
potential of the oil palm, there is problem with soil
borne fungus C. paradoxa causing black seed rot disease
in oil palm sprouted seeds. The cause of the dry basal rot
in adult palm, conducted by Robertson (1962), was
shown to be due to the Ascomycete, C. paradoxa of
which the imperfect stage is known as Thielaviopsis
paradoxa. It is a soil inhabitant, widely distributed throughout
the tropics of Africa and Asia and causes disease
of several other crops (Rajagopalan, 1965).
