C. citratus or lemongrass is a perennial tropical grass; it is resistant to different temperatures and can grow in all climates. The essential oil from C. citratus, besides having antimicrobial effects, has been shown to have anti-inflammatory, analgesic and antipyretic properties (Kpoviessi et al., 2014; Vázquez-Briones et al., 2015). Mentha piperita L., a medicinally important plant belonging to the family Lamiaceae and commonly known as peppermint is a hybrid of Mentha spicata L. and Mentha aquatic. The extracts of Mentha piperita are found to possess antibacterial, antiviral and antifungal activities (Singh et al., 2016; Ilboudo et al., 2016). The leaves of Eucalyptus camaldulensis are usually used for various purposes, including treatment of infections. All these plants are grown traditionally on small or large areas everywhere in Burkina Faso, so interesting candidates for biological control of bacterial diseases.
