Abstract Erythrophleum ivorense efficacy of its steep water extract to control yellow stem borer in maize plant during the growth and vegetative stages was investigated in the Science laboratory Department of Federal Polytechnic, Auchi, Edo State, Nigeria. The extract (steep water) was applied at the rate of 0 (control), 5, 10, 15 and 20 mlkg-1. The result obtained showed that Erthrophleum ivorense (water extract) at 10mlkg-1 to 20mlkg-1 were effective in the control of stem borer at 0.01% level of significance. It also revealed the strong insecticidal action of E. ivorense on maize insect pest. However, with increasing concentration of the E. ivorense at 20mlkg-1, giving the highest mortality rate residual action and the reproductive at 89.15%, 76% and 0% respectively. This finding provides a good resource for poor farmers in developing countries who will find this trial affordable than buying chemical pesticides. Keywords: Erythrophleum ivorense, (steep water extract) maize, stem borer and Bio-pesticides.
