Efficacy of Jute Bags Impregnated with Plant Extracts in the Post-Harvest Protection of Cowpeas in Benin

Abstract

The biological efficacy of jute bags impregnated with Eucalyptus camaldulensis, Cymbopogon citratus essential oils, and vegetable oil of Azadirachta indica was evaluated on the adults of Callosobruchus maculatus of cowpea and the molds of the genus Aspergilus and Penicillium, in post-harvest conservation conditions. The results reveal that the jute bags tested have significant insecticidal and antimicrobial activity on Callosobruchus maculatus adults, when the dose and exposure time increase from 0 to 2% for 26 weeks.
