Abstract
This research was carried out at the Teaching and Research Farm of the
University of Ilorin, to evaluate the use of some fungi as bio-agents in
management of nematode pests of two varieties of maize. The
experimental design was a Randomized Complete Block Design (RCBD),
having two plots and four treatments with Fusarium oxysporum,
Phomopsis sp., their combination and the control. Treatments were
replicated three times. The varieties used were EVDT 99 and Oba Super
II. The initial soil nematode population was increased by chopping galled
roots of Celosia argentea into the soil. Two seeds per hole were planted
out on the ploughed and harrowed ridges and were later thinned down to
one seedling per stand. Data collections were done for a period of nine
weeks and at harvest. The results showed that the plants on the treated
plots performed significantly higher (P=0.05) than the control in terms of
height, number of branches, yield and the reduction of soil nematode
population and root galls. This study, established that at certain levels of
application, Fusarium oxysporum and Phomopsis sp. exhibited fungal
endophytes against parasitic nematodes of plant. Therefore, there is a need
to identify the strains of the fungi which were used in this study in order to
increase and incorporate them in sustainable agriculture
