Bioherbicidal Activity of Aromatic Plants’ Hydrodistillation Water Residues Against Avena sterilis and Echinochloa crus-galli, with Selectivity for Zea mays

The demand for sustainable weed management and the limited discovery of new herbicide molecules have led to high interest in plant-derived bioherbicides, such as the water residues (WRs) from the hydrodistillation of aromatic plants, which contain biologically active secondary metabolites. Here, the bioherbicidal activity of WRs of four aromatic plant species was investigated. Chemical composition of WRs was determined by solid-phase microextraction (SPME) coupled to gas chromatography–mass spec
