Abstract
Evaluation on the Effect of Sustainable Environmental Friendly Bio Pesticides Application on the Growth of Seed borne Fungi on Cowpea (Vigna unguiculata L. Walp.) was conducted at the Department of Crop and Soil Science Laboratory, Niger Delta University, Wilberforce Island, Bayelsa State, Nigeria. To determine the percentage (%) efficacy of plant essential oils and to evaluate the best plant essential oil on the suppression of the pathogen cultured and treated Potatoes Dextrose Agar (PDA) plates with the different plant essential oils concentration levels (0.1, 0.01, and 0.001%). This experiment was arranged in Complete Randomized Design (CRD) and each treatment was replicated three times and each replicate contained 12 petri dishes. The result shows that ginger oil at 0.1 in all the days of the bioassay assessment, particularly, from day 6-day10 proved more effective in suppressing the teste pathogen (A. niger), this could be the present of the active ingredient (Zingerone) on the treatment. Therefore, this result should be encouraged for Cowpea farmers as seed treatment before storage to prevent Cowpea weevils (Callosobruchus maculatus) as a grain storage insect pest, that causes serious destruction on the stored grains.
