The comparative study of effects of different concentrations (g) of leaf powder of Erythrina senegalensis on maize weevil (Sitophylus zeamais Motschulsky) and percentage germination of treated grains at 336 hours (14 days) was carried out. Mortality and % mortality of weevils increased with time of exposure, up to 336 hours after treatment (HAT). Analysis of Variance (ANOVA) on these parameters indicated significant difference (P<0.05) of the effect of different concentrations of the plant extract over the control (0.0g). Similarly, there were significant reduction (P<0.05) in weight loss and grain perforation with increase in level (g) of leaf extract at 336 HAT. Weevil perforation index (WPI) revealed the highest protective potential of 13.64 and 22.73 for 10.0g and 8.0g (w/w) levels respectively at 336HAT. Germination test of treated grains at this period showed no significant difference (P>0.05) in % germination at 72 and 120 hours after planting (HAP), and significant difference (P<0.05) at 96 HAP, indicating the effectiveness of the leaf powder of Erythrina senegalenses as a good potential seed-dressing option, thus ensuring a sustainable preservation of planting stock with an eco-friendly strategy.
