Development of bioherbicides combining essential oils and organic acids

This poster presents the development and evaluation of a bioherbicide within the framework of the European CONSERWA project, which supports agroecological approaches to weed management. Various essential oil compounds were screened for their phytotoxic effects in both pre-emergence and post-emergence assays. Their surface-active properties, including wettability, were assessed to better understand their behavior on plant surfaces. These results served as a foundation for formulating combinations with organic acids (acetic and lactic), aiming to enhance herbicidal efficacy while reducing the required concentration of essential oils.
